Thermostats

By | Commercial, Cooling, Heating, Home Monitoring, Residential, Thermostats

In 2018 the Miami Valley probably used their heating and cooling systems a lot. According to Wunderground, we had 178 days with temperature highs below 60° Fahrenheit, and 108 days with temperature highs over 80° F. That means that for most people they could have their HVAC systems on over 75% of the time. It could be argued that the single, most important part, of any heating and cooling system is the control that operates the system. A low voltage thermostat is the main control for your building that determines how much heating or cooling will be delivered to satisfy the temperature set on the thermostat. Thermostats have advanced a long way in the past 10-20 years as much technology has. The focus for updating thermostats has been on energy savings, cleaner air, comfort, simplicity, quality, accessibility, and easy to understand information among other issues all related to customer satisfaction. Modern thermostats have a lot of features to appeal to everyone, from simple to read displays to utility savings a modern thermostat is an easy upgrade to add to your system to start saving money for years to come. According to First Energy, based on typical energy costs, a smart thermostat can save up to $145 a year. Models rated for Energy Star compliance offer rebates from utility companies as well.

How it Works

Whether a low voltage thermostat is old or new, the way it works is pretty similar even if the parts inside are not. A part of the thermostat is a way to measure the current temperature in the area it is installed, older models had bimetallic strips, while modern models use electronic controls to sense temperature changes. When the strip or thermistor registers a temperature below or above the set temperature it triggers the heating or cooling unit to turn on to maintain the temperature set. Programmable thermostats allow the user to preset temperatures, allowing them to change according to the owner’s programmed settings. Some of those programmed settings examples could be temperature set points at night, work, and vacations. Wi-Fi enabled thermostats allow the owner to check on their system wherever and whenever they like, assuming they have Wi-Fi and/or cellular service. Other features such as maintenance reminders, humidity level display, weather forecasts, energy reporting, zoning compatible, wireless room sensors, smart recovery, AC overcool to dehumidify, service alerts, and more can be found on certain thermostats.

Types

  • Non-Programmable – Non-Programmable thermostats can be mechanical or digital. To adjust the temperature or change from heating to cooling the owner would walk directly to the thermostat to make changes.
  • Programmable – Programmable thermostat come in a variety of programming options, some models makes changes for a week, some for weekdays and weekends, and some models offer more in-depth programmable options including each individual day. Once the thermostat is programmed the idea is that the owner would set up the thermostat according to their own comfort level and the thermostat would adjust on its own as needed, to the schedule you have programmed.
  • Wi-Fi – Wi-Fi thermostats or smart thermostats give the owner the option to not only program the thermostat but to have it adjust to you as well. With features like room sensors, occupancy sensor, and learning technology. These thermostats can adjust to your schedule inside the building. Some models can even change from heating to cooling or vice versa when needed to maintain the set temperature on the thermostat. These models can give even more features to the owner such as enhanced fan control, IAQ integration, weather forecasts, maintenance reminders, smart home/away, and more. A few of these models qualify for utility company rebates.
  • Communicating Controller – Available with variable speed equipment, communicating controllers allow the owner to be the most comfortable. With longer heating and cooling cycles at lower fan speeds, the air is better treated to ensure the best air quality and comfort possible. Other features include energy tracking and reporting, better humidity control, better dehumidification control, and multi-zone compatibility. These models can even alert Hauck Bros. of a major service issue as it happens so we can assist you as quickly as possible.

Comfort

Comfort starts with the thermostat and is backed up by the equipment and Indoor air quality products that maintain your personal comfort level. The thermostat is the control of comfort for your home or business. Depending on the model, the thermostat can save money via programming, provide ease of access with Wi-Fi, send reminders for maintenance alerts, learn to adjust to your comfort level on your schedule, manage humidity levels, and much more.

Features

  • AC Overcool, uses the condensing unit to reduce humidity by cooling your building beyond the desired temperature until the desired humidity level is reached in your home or business.
  • Auto change, also called Auto Mode, Allows the thermostat to switch from Heat to Cool or Cool to Heat automatically.
  • C-Wire, “Common” wire, enables 24 VAC power to the thermostat continuously.
  • Dual Fuel Capable, when a gas furnace and Heat Pump are used in a building. Allows the furnace to take over heating when the heat pump is inefficient.
  • Energy Star Qualified, required to work as a basic thermostat if on-line service is lost, provide information about HVAC energy usage, give residents feedback about energy consequences of changing settings, and provide the owner the ability to schedule or program. By adjusting the temperature down or up by 7-10 degrees from the normal setting owners can save up to 10% on heating and cooling costs.
  • Enhanced Fan Control, with a communicating controller, allows the user to adjust the continuous fan speed to low, medium, high, or off.
  • Thermostat Occupancy Sensor, indoor motion detecting sensor that can detect the presence of a person to automatically control the thermostat to adjust to a temperature preset setting.
  • Outdoor Air temperature Sensor, on select models of thermostats and zoning systems, provides outdoor air temperature information for the control system and the owner as well.
  • Thermostat Maintenance Reminder, certain models will remind owners to change the filter, ultraviolet light bulb, humidifier pad, and even the ventilator pre-filter
  • Thermostat Password Protection, certain models allow the owner to lockout the control by programming a password to prevent changes.
  • Programmable Thermostat, allows the user to schedule the thermostat to maximize home comfort and save money on utilities.
  • Self-Programming Thermostat, certain models learn what temperature you like and adjusts the schedule automatically
  • Service Safety Alerts, depending on the model some thermostats have the ability to notify you via your smart device, e-mail, and even send out an alert to your HVAC service provider when your HVAC system might be having an issue. Some examples of alerts are too high of humidity in the building, HVAC system not operational, and too high or too low of a temperature
  • Smart Home / Away, some models of thermostats have an occupancy sensor that detects when someone is home or not. These models have the ability to go into energy saving mode when you are away or to override the energy saving mode to ensure your comfort is met when you are home, regardless of the programming.
  • Smart Recovery, depending on the thermostat, some models have the ability to start cooling or heating your building so that at the time set for a certain temperature set point the temperature will already be at the set point.
  • Smart Speaker Compatible Thermostat, certain models of thermostats have the ability to be connected to your home automation provider. This allows the owner with proper registration to control the thermostat by voice or within that providers app.
  • Staging Settings, with multi speed HVAC equipment, having the proper thermostat to control the which stage the equipment is necessary. This allows the equipment to run in the lower stage or stages before going into higher stages.
  • Touchscreen, with technology improvements in thermostats, most modern digital thermostats come with a touchscreen, similar to that of a smart device.
  • Wi-Fi, A lot of modern thermostats have Wi-Fi capability. Wi-Fi allows the owner to control the thermostat from their smart device or within an app, keep the thermostat updated and secure, and help on energy savings.

 

Efficiency

Using a programmable thermostat in your building will let you run a scheduled heating and cooling program without having to manually adjust the settings throughout the day. Depending on the thermostat setting up a program can be done on the thermostat and if the thermostat is connected to an app or a smart device, it can be done on the computer or smart device. Adjusting the program to lower or allowing the temperature to rise by 7-10 degrees can save up to 10% in utility costs.

DIY

Make sure to check your thermostat once a year to ensure (depending on the model) that it is level, batteries are replaced (if applicable), and clear of dust and debris. It’s always a good idea to test the heating and cooling equipment before their season to ensure the thermostat is operational and the equipment responds as well. Some models with automatic reminders set up will need the reminders reset ex. change air filter or humidifier pad.

Service or Replace

The thermostat should be maintained and checked once a year, if it has no power, doesn’t respond to settings changes, heating or cooling won’t turn on, or loses its programming it might be time to consider a replacement. If your system is being replaced and it was over 15 years old and you would like to take advantage of the energy efficiency of a modern thermostat, replacement should be considered. Even if you have a programmable thermostat but you want the benefits of the features modern thermostats offer, consider replacement.

Accessories

  • Backplate, in some cases new thermostats are smaller than old thermostats, these backplates are needed to cover the space used by the old thermostat for cosmetic appeal.
  • Thermostat Cover, in some buildings commercial and residential, the thermostat needs to be protected and secured to limit access. A cover goes over the thermostat while providing airflow to the unit to ensure proper temperature control.
  • Room Sensor, some models of thermostats have the ability to have a wired or wireless room sensors connected to it. This allows for the user to adjust temperature based not only on the main thermostat but with input from the sensor as well. The most common options for sensors within the thermostat are to average the two or more temperature readings, use the sensor as the main temperature set point, and to follow the sensor wherever it is moved in the house to maintain the set point.
boilers

Boilers

By | Boilers, Heating

In the Miami Valley, boilers still have a role to play in heating your house or business. Modern boilers heat and treat indoor air while being more energy efficient than older units. You can rely on the professionals at Hauck Bros., Inc. to install a boiler for the first time, replace an outdated or boiler, or service your current system. Since 1921, we proudly serve both residential and commercial customers with the industry’s leading equipment that will provide comfort for years to come.

How it works

A boiler is a sealed system that contains the combustion of fuel, including coal, oil, natural gas, and liquid propane to heat water. Boilers use hot water distributed throughout the building in pipes to provide heat a heat transfer. This allows for individual controlled heat to each room, or zoning.

Types

  • Fire Tube – Fire tube boilers confine the combustion process and gases in tubes and water circulates around these tubes. Some fire tube boilers have turbulators inside of the tubes to cause turbulence of the flue gases. This increases the heat absorption into the water which makes the boiler more efficient. They are generally used for medium to large boiler commercial/industrial applications. These boilers can be either steam or hot water boilers in low to medium pressure applications.
  • Water Tube – Water tube boilers have many different tubes inside of it that have water circulating through them. Hot combustion gases surround these tubes and an exchange of heat is realized. The heat exchange is between the combustion gases and the tubes and water. The water tube boilers can be built for higher capacities and pressures than the fire tube boilers because the steam and/or hot water is confined in the tubes. These boilers are generally found in medium to large commercial/industrial applications.
  • Steam Boiler – delivers hot steam to radiators and bring back cooled condensation into the boiler system to be reheated. Steam boiler need a pressure relief valve and a low water cutoff. Most steam boiler have manual valve to allow for added water to enter the system when needed.
  • Hot Water Boiler – use a series of pumps to circulate heated water through the building and into the radiators. Hot water boiler systems typically have an expansion tank.

Fuel Types

When it comes to boilers, the fuel type helps distinguish which type of boiler you may need and the features available to your setup as well. For most residential and commercial applications, natural gas, liquid propane, electric, and oil are the main source of fuel.

Comfort

Modern boilers have the ability to keep you comfortable during the heating season in a variety of ways. Some models are designed to be easy to service, with annual maintenance recommended on every boiler, having the unit easy to service makes it easier to repair a problem which could save you time and money. The more efficient the boiler the more it saves you on heating bills, especially over 15 years. Some models are quieter than others depending on the design and functionality.

Features

Efficiency

Older units have a rating of 56%-70% AFUE rating. Newer non-condensing units have a 80%-88% AFUE rating. Newer condensing units have an 89%-95% AFUE rating. Condensing units have a secondary heat exchanger for better efficiency. Based on the US National Average for 2017, an 80% AFUE unit would save over $7,500 vs a 60% AFUE over 15 years. A 90%+ AFUE unit would save over $10,000 over 15 years.

Combination Boiler

Traditional boilers and combination boiler share the same task of heating your home by going through your system to radiators or radiant floor systems where it provides heat to warm the air. Traditional boilers heat water in a tank on constantly, ready to provide heated water when needed. Combination boilers has no storage tank, it heats the water as needed and can provide hot water for the whole house, one source at a time. A combination boiler is great choice for a smaller building, with little need for constant hot water.

Ease of Service

Look for models that are easy to service to save time and money on annual maintenance charges. Make sure a certified technician proves annual maintenance to avoid breakdowns and extend the life of the boiler.

Heat Exchanger

When doing a replacement or refurbishment project, the existing heating design dictates what can and cannot be done. New construction or builds offer more freedom in the heating design, but can be more restrictive on building regulations. There are 4 different main heat exchangers to choose from.
1. Cast Iron, heavy, but not easy to break, cast iron feature a sectional heat exchanger design. Ideal for replacements due to their ability debris from the older system. Tend to not be energy efficient unless they have a secondary heat exchanger that enables the boiler to condense.
2. Aluminum, lightweight and excellent at heat transfers, they can be used with other materials to enhance their overall strength. Good water quality must be provided to avoid corrosion.
3. Stainless steel, heavier and able to take more corrosive water. Grade 316 is the most common type, which allows for good welding and heat transfer properties
4. Steel and Tube, used in higher output systems. They can corrode easily, and our not suitable for condensing without a secondary heat exchanger. Usually used in commercial and industrial type buildings.

Energy Efficiency

For residential units under 300,00 BTUH of input, boiler efficiency is measure by AFUE (Annual Fuel Utilization Efficiency). AFUE is a calculated efficiency which attempts to estimate how well the boiler coverts the energy in its fuel to heat over the course of one year. Simply put, older furnaces had as low as a 56% AFUE rating, there are models today that can get above a 95% AFUE rating. The higher the AFUE the more efficient the unit is, this saves money on utility bills in the future. Based on the US National Average for 2017, an 80% AFUE unit would save over $7,500 vs a 60% AFUE over 15 years. A 90%+ AFUE unit would save over $10,000 over 15 years.

DIY

Boilers need regular maintenance to prevent breakdowns and, in some cases, to keep the warranty valid and active. There are some simple checks you can do to make sure your boiler stays out of trouble.

  • Make sure all air vents are working, not blocked, and clear of debris around them on the interior and exterior of the building.
  • Make sure to check the water level, if it operates without water the boiler could be seriously damaged.
  • Make sure the pilot light is light (if applicable)
  • Check for leaks and cracks
  • Keep the room the boiler is in as dust free as possible

If you are uncomfortable doing any of these tasks, please contact us at 937-325-0636 or fill out this form and we will reach out to you within 24 hours.

Service

Boilers need regular maintenance once a year. There are two great reasons to have a boiler maintained annually. First, having an annual maintenance check done helps prevents sudden failures. Second, some manufactures require annual maintenance to keep their warranties valid. During the inspection our technician will check shut off valves to ensure they are working properly, check the refractory, check for cracks, check the controls, check indicators, and safety devices to ensure they are all working properly. The technician will also inspect the fuel feed systems and clean the burners to ensure they are working properly.

Signs your boiler may need replaced

  1. Increased failure rate of the boiler
  2. Yellow flames on gas burners and black soot on oil boilers, indicates the fuel is not burning properly, this can create carbon dioxide.
  3. Leakage, if the boiler needs more water to run than it might have a leak. Consider replacing before flooding occurs.
  4. Age, most condensing boilers last for 15+ years, cast iron 20-30 years, with proper annual maintenance by a licensed technician.
  5. Energy use, older boilers are not as energy efficient as modern boilers
  6. Comfort, if your building starts to have hot or cold spots in areas that it didn’t before, it could be that the unit is not operating as efficiently as it once did.
furnaces

Furnaces

By | Heating

In the Miami Valley, a reliable furnace is a necessity.  Modern furnaces’ equipment heats and treats indoor air while being more energy efficient than older units.  You can rely on the professionals at Hauck Bros., Inc. to install a new furnace for the first time, replace an outdated furnace, or service your current system. Since 1921, we proudly serve both residential and commercial customers with the industry’s leading equipment that will provide comfort for years to come.

How it works

Depending on the fuel type, natural gas, liquid propane, electric, or oil, a furnace operates using forced air to transfer heat to air.  The blower then sends that air throughout the connected duct work into the house or business, and then out through the vents.  In a natural gas, oil, and liquid propane furnace, a pilot light ignites a series of burners inside the combustion chamber. The heat created from the burner enters the heat exchanger and transfers the heat to the air while raising the temperature set at the thermostat. The blower then takes the air and sends it through the ducts.  An electric furnace uses an electrical ignition source instead of a pilot light to start the heating process. An electric furnace has conductive coils that work to heat the air for the blower to use in heating.

Types

Fuel Types

  • Oil, with AFUE ratings up to 86.6% efficiency, and some other models offer variable speed operation. Oil furnaces provide dependable heat and can be paired with a heat pump or an air conditioner to provide maximum comfort throughout the year. Offering flexible installation options, oil furnaces come in traditional multi-poise models or low boy models.
  • Gas, Natural Gas or Liquid Propane, with AFUE Ratings up to 98.3% and a model with modulating gas valves and a variable speed fan, gas furnaces provide dependable heat and can be paired with a heat pump or an air conditioner to provide maximum comfort throughout the year. These models can be installed vertically or horizontally to accommodate various installation needs.
  • Electric, available as an all-electric furnace or an air handler with electric strips paired with a heat pump. These models can come with Variable Speed operation and paired with a heat pump can provide maximum comfort throughout the year. These models can be installed vertically or horizontally to accommodate various installation needs. Heat strips can be used in an air handler paired with a heat pump to serve as a back up to the heat pump for extreme cold situations.
  • Available in:
    • Single Stage
      • A single stage unit turns on when indoor temperatures exceed the temperature setting on your thermostat. Once the temperature set on the thermostat is reached it turns off again. Single stage furnaces always operate at 100% capacity.
    • Two Stage
      • More efficient than single stage units, these units vary their output between two levels: high and low. Ideally, the low stage would satisfy the thermostat most of the time. When necessary, the high stage would turn on. This helps eliminate temperature swings and helps to better condition the air, making you feel more comfortable for longer periods of time.
    • Variable Speed
      • Variable speed units precisely control the airflow throughout your home in order to maintain the highest level of comfort. This allows the unit to run continuously, while consuming far less electricity than a single stage unit. The constant airflow has some key benefits, maximum conditioning and treatment of the air, less hot and cold drafts, and quieter operation.

Comfort

Furnaces play a big role in keeping home and businesses comfortable during cold days. Being able to raise the temperature inside allows for people to stay warm and comfortable.

The temperature that feels comfortable may be different for everyone. With variable speed furnaces, having the air move constantly allows for better dehumidification during the cooling season when paired with an air conditioner or a heat pump and better humidification when paired with a humidifier during the heating season. Variable speed fans help better filtration and the lessening of hot and cold spots as well. Even with two-speed operation, having the low speed on the majority of the time makes the treated air feel more comfortable.

Features

Variable speed ECM Blower, the variable speed electronically commutated blower precisely and efficiently controls the flow of heated or cooled air throughout your home via ductwork. This allows for better airflow that reduces temperature swings as well as constantly treating the air for filtration and humidity management.

Multi Speed ECM Blower, the multi speed electronically commutated blower can also adjust airflow like a variable speed blower but less precisely.  They have up to 5 speeds available that change based on your airflow needs.

PSC blower, the permanent split capacitor blower does not adjust airflow. It is set to one speed and operates at that speed 100% of the time.

Modulating Gas Valve, found in the most efficient gas furnaces, the modulating gas valve allows for better comfort by turning on more frequently but at a lower stages to condition the air before 100% capacity is needed.

Energy Efficiency

The efficiency of furnaces is measured by Annual Fuel Utilization Efficiency (AFUE). AFUE is a measure of how efficient the unit is in converting energy from its fuel source to heat over the course of a typical year. AFUE is the ratio of annual heat output of the furnace compared to the annual fossil fuel energy consumed by a furnace. An AFUE rating of 95% means that 95% of the energy in the fuel type becomes heat for the building and the other 5% escapes to the outside of the building through the ventilation system. Electric furnaces installed inside a building have zero loss.  The Federal Trade Commission (FTC) requires all new furnaces to display their AFUE ratings so consumers can compare their different efficiencies.

Older units have a rating of 56%-70% AFUE rating. Newer non-condensing units have a 80%-83% AFUE rating. Newer condensing units have an 90%-98.5% AFUE rating. Condensing units have a secondary heat exchanger for better efficiency. Based on the US National Average for 2017, an 80% AFUE unit would save over $7,500 vs a 60% AFUE over 15 years.  A 90%+ AFUE unit would save over $10,000 over 15 years.

DIY

  • Check to make sure the furnace pilot light is on, if not lit re-light according the manufacturer owners manual.
  • Make sure all return and supply registers are clean and unobstructed.
  • Make sure to check and change or clean the air filter, on some models at least once a month.
  • Make sure the area around the furnace is clear of debris and combustible materials.
  • Check your thermostat and turn to heat to make sure it comes on.
  • Check to make sure your Oil or Liquid Propane tanks are full. Generally, they are cheaper to fill during the cooling season than the heating season.

Service

With normal maintenance and care, furnaces can last over 20 years!  Our experienced technicians can help you maintain the life of your equipment by performing a Home Comfort Protection Plan check on your furnace. Some inspections the technician will perform are checking the air filter, blower motor, blower wheel, transformer, gas leaks, flame sensor, thermostat, and more!

mini splits - ductless

Mini Splits/Ductless Systems

By | Cooling, Duct Free Systems, Heating

How it works

There are a lot of applications that a ductless system can be used for In the Miami Valley. Mini split systems can be used for alleviating a hot or cold spot, help heat and cool a renovation or new construction, and even provide comfort for light commercial use. With many types of installation options available there aren’t many situations that a ductless system can’t help with.

Similar to standard air-source heats pumps, mini split systems have two main components, an outdoor condensing unit and an indoor air-handling unit. The link between the two units is called the conduit, it houses the power cable, refrigerant tubing, suction tubing, and a condensate drain. Ductless systems are available where no ductwork is needed while ducted mini split systems can use little ductwork in the ceiling or below the floor. The unit or units will operate to reach the temperature set on either thermostat or remote control. Some models can be controlled via a smart device as well.

Types

With many different application types and installation options their are a lot of options available:

Outdoor Units

  • Single Zoned Cooling Only, designed to provide a high comfort level to a single room for cooling purposes only while being energy efficient (up to 24.6 SEER) and very quiet (low as 48 dB).
  • Single Zoned Cooling and Heating, designed to provide a high comfort level to a single room for cooling and heating purposes year-round. Some models are designed to provide outstanding heating performance even in extreme cold. Models can be energy efficient (up to 42 SEER & 15 HSPF), quiet (as low as 47 dB),
  • Multi Zoned Cooling and Heating, Designed for whole building comfort for cooling and heating purposes. One outdoor unit can support up to 8 indoor units and each zone can be individually controlled to meet personal comfort needs. Units can be energy efficient (up to 23.8 SEER & 12 HSPF) and quiet, (as low as 49 dB)

Indoor Units

  • Wall Mounted, designed to provide cooling and heating to an individual room while monitoring room conditions and self-adjusting the fan for ideal personal comfort. Units can be very energy efficient (up to 33.1 SEER & 13.5 HSPF) and quiet (as low as 19 dB), cooling only, and available in 3 speed or 5 speed fan speeds.
  • Horizontal Ducted, designed to use ductwork which can be concealed in the ceiling or below the floor. Ideal for new construction or renovations. Units can be energy efficient (up to 19.6 SEER & 12.1 HSPF), quiet (as low as 23 dB) with 3 fan speeds.
  • Ceiling Cassette, designed to fit between standard 16” joists to provide cooling and heating to one area. Great option for renovations, new construction, and light commercial. Units can be energy efficient with SEER Ratings up to 19.6 and HSPF up to 12.1 while be quiet with Db levels as low as 24, with 3 fan speeds
  • Floor Mounted, designed to fit in rooms with little vertical wall height where a wall unit or ceiling unit will not fit to provide a room with cooling and heating. Units can be energy efficient with up to 28.2 SEER and up to 13.6 HSPF, while being quiet with dB rating as low as 21, with 5 fan speeds.
  • Ducted Air Handler, designed to accommodate new construction, renovations, replacements, and light commercial to provide heating and cooling through ductwork. Can be installed vertically or horizontally. Can be broken down to fit through tight access points and reassembled. Units can be energy efficient with SEER ratings up to 21.4 and HSPF up to 10.4 while be quiet with dB levels as low as 27 with 3 fan speeds.

Comfort

Mini split systems are designed to offer cooling and heating to rooms or areas to provide comfort to occupants. Designed to be energy efficient, easy to install, quiet, and easily adjustable to provide year-round comfort to make your living space comfort what you want it to be.

Features

Indoor Air Quality (IAQ), mini splits are designed to treat the air in the area in which it installed. Filters are installed on all indoor units and some models can capture and remove allergens, odors, and other contaminants to make your air clean and keep you healthy.

Extreme Low Temperature Heating, some models are designed to provide comfortable indoor temperatures even during the coldest days (as low as -13 degree F)

Quiet, without ductwork or with little ductwork mini split systems are designed to deliver cooling and heating directly to the rooms they are intended to serve which means there is no need for fans, keeping the noise down, outdoor units as low as 48 dB and indoor units as low as 19 dB.

Energy Efficiency

SEER (Seasonal Energy Efficiency Rating) is a ratio of the amount of cooling produced (BTU) divided by the amount of electricity (watts) used. The difference between SEER and EER is that SEER accounts for changes in outside temperature instead of just one temperature. EER should be used as a comparison when the outside temperature is consistently over 95 degrees F.

The higher the SEER the greater the heat pump’s efficiency could be. Generally, most single stage heat pumps rate from 14 to 16 SEER. Two Stage units rate from 17 to 19. Variable speed units rate from 18 to 21. Comparing against a 10 SEER heat pump over 15 years*, a 14 SEER could save $1395, a 16 SEER could save $1,830, and a 21 SEER could save $2,550.

HSPF (High Seasonal Performance Factor) represents the total heating output of a heat pump (including supplementary electric heat) during the normal heating season (in BTU) as compared to the total electricity consumed (in watt-hours) during the same period.

DIY

With normal maintenance and care mini split systems can last over 20 years. Make sure to keep the filters and coils clean. Make sure the outdoor unit is free from obstruction and the unit is free of debris. Check the drain pan to ensure it stays clear of moisture. Inspect the refrigerant lines, visually confirming the lines are insulated and not damaged.

Service

Our experienced technicians can help you maintain the life of your equipment by performing a HCPP check on your mini split system. Some checks the technician will perform are refrigerant levels, ensure the coils are clean, check the drain pan, check the entire outdoor unit, inspect the refrigerant lines, and ensure the units are set to manufactures specifications.

evaporator coil

Evaporator Coils

By | Cooling, Heat Pumps, Heating, Residential

An evaporator coil is the part of an air conditioner or heat pump that absorbs the heat from the air in your house. It is located inside the air handler or attached to the furnace.

How it works

Located inside the blower compartment or air handler, the evaporator coil holds the chilled refrigerant that the compressor moves into it.  As the air from the blower fan moves over the coil, the cold refrigerant removes the heat from your home’s air. The refrigerant becomes warmer and travels to the condenser coil outdoors.

With a heat pump, the process reverses in the winter and the evaporator coil expels heat from the refrigerant into your home, instead of absorbing it and taking it outdoors. Most heat pumps have auxiliary heating elements that are part of the evaporator coil components to supply heat when temperatures fall below a certain point.

Types

  • A-Coils – Shaped like an A, produce better airflow which allows for the most efficient airflow allowing for high efficiency ratings.
  • N-Coils – Shaped like an N, are more compact than A-coils and are better suited for tighter applications.
  • Slab Coil – When the coil has to be installed horizontally, these are preferred.

Features

  • ENVIRONMENTALLY SOUND, ENERGY-EFFICIENT – Bryant® Preferred™ Series aluminum evaporator coils are designed for use with Puron® refrigerant to provide years of environmentally sound, trouble-free performance.
  • ENHANCED COMFORT – Our Thermostatic Expansion Valve (TXV) ensures proper refrigerant flow during fluctuating pressures and conditions for top reliability and energy-efficient operation.
  • DURABILITY AND DRAINAGE – Our base pan is made of a corrosion-resistant composite material. Integrated sloped drainage helps reduce build-up of mold, bacteria and other airborne pollutants.
  • LASTING LOOKS AND PERFORMANCE – The sturdy cabinet on our cased models is painted to match your Bryant® furnace to provide years of scratch resistant good looks. (Models CAPVP, CAPMP, CNPVP, CNPHP, CSPHP)
  • LONGER LIFE – Bryant advancements in aluminum manufacturing technology result in higher product reliability.

heat pump comfort features

Comfort Features – Heat Pump

By | Cooling, Heat Pumps, Heating

It might seem difficult to think about something called a “heat pump” being of practical use in the summer, but fear not – a heat pump can also cool your home!  Not only that, it does so in an efficient manner and can save you money in energy costs.  ENERGY STAR certified heat pumps have higher ratings for seasonal energy efficiency ratio (SEER), energy efficiency ratio (EER), and heating seasonal performance factor (HSPF) and use about 5% percent less energy than conventional new models.

Most importantly though, it does a great job of keeping you comfortable in your home.

Thermostat

Heat pumps, like traditional central air conditioning and furnaces, can be controlled with a thermostat.  Having a thermostat that can auto change between heating and cooling is essential. New technology like Bryant Evolution Connex and Bryant Housewise allow Wi-Fi connections that allow you to manage your home’s temperature settings from anywhere, keeping you cool in the summer and warm in the winter.

Back-Up Heating

Normally, air-source heat pumps contain a second source of heat that help warm your home on days when the unit is unable to draw enough warmth from outdoor air.  This is done using electric heat strips within the unit.  Hybrid units combine an electric heat pump and a propane or gas furnace into one, providing a much more energy-efficient alternative.

Dehumidification

We’ve talked about variable fan motor speeds in this space previously, and an added benefit for comfort is a two-stage or variable speed heat pump.  These units run with lower airflow, which reduces temperature swings as well as humidity in the space, making you more comfortable.  The compressor will run longer, but at a lower speed, allowing the air to be treated more efficiently.

Quality Features – Heat Pump

In the Miami Valley, air source heat pumps can be a viable option for your heating and cooling needs. They use electricity and are much more efficient than resistance heating units like furnaces and baseboard heaters. High efficiency air source heat pumps can also dehumidify better than standard air conditioners, resulting in less energy use and more thermal comfort during the summer months.

How it works

How does an air source heat pump work?

Like an air conditioner, air source heat pumps have the ability to transfer heat between the building and outside air.  Air source heat pumps also have the ability to heat your building as well.  Each Heat pump has   refrigerant system, which is a compressor and two copper tube coils, one outside and one inside, and the outside coil, which is encased in aluminum fins.  The refrigerant system extracts heat from the refrigerant as it condenses back to liquid for both heating and cooling with a reversing valve. The blower than moves that air though the building ductwork. When the thermostat is satisfied, the unit shuts off.

Compressor Type

When heat pumps were first developed, they used a single speed compressor that only operated at full capacity, thus using more energy and causing it to wear out faster.  Two-speed compressors allow operation at a lower level, which reduces wear and tear and can allow the heat pump to keep different rooms at different temperatures, provided a zone control system is installed.

Single Stage

A single stage air source heat pump turns on when indoor temperatures exceed or are below the temperature setting on your thermostat. Once the temperature set on the thermostat is reached it turns off again. Single stage heat pumps always operate at 100% capacity.

Two Stage

More efficient than single stage units, two stage heat pumps vary their output between two levels: high and low. Ideally, the low stage would satisfy the thermostat most of the time. When necessary, the high stage would turn on. This helps eliminate temperature swings and helps to dehumidify the air, making you feel more comfortable for longer periods of time.

Variable Speed

Variable speed air conditioners precisely control the airflow throughout your home in order to maintain the highest level of comfort. This allows the air conditioner to run continuously, while consuming far less electricity than a single stage air conditioner. The constant airflow has some key benefits: maximum air filtration, dehumidification, minimum cold spots and quieter operation.

Comfort

Heat pumps can be quiet, with models available up to 58 DB. Two stage and Variable speed units with a humidifier help to humidify the air more efficiently during heating cycles and also dehumidify air more efficiently as well during cooling cycles.  Used with an back up furnace, heat pumps can ensure your year round comfort and energy efficiency.

Blower Speed

The type of fan motor can also impact energy savings and air comfort.  A dual-speed or variable-speed motor reduces noise from the blower always running at full speed, and it also keeps air moving comfortably.

Geothermal Heat Pumps

Looking for even bigger savings down the road?  Geothermal heat pumps use the environment around them to transfer heat between the ground (or a nearby water source) and your house.  Since ground and water temperatures remain more constant than air temperatures, the cost to operate these is much lower and can reduce energy use by as much as 50%.
