Why is Your AC Blowing Warm Air?

By Air Conditioning

When the summer heat is ramping up, the last thing you want is for your air conditioner to be blowing warm air into your house. Your home should be a comfortable sanctuary away from the heat. A malfunctioning AC can lead to higher energy bills and even health problems, not to mention the frustration of being uncomfortably hot.

There is a multitude of reasons your AC could be blowing out warm air, from simple issues with your settings to more complex problems. In this post, we will examine some of the most common causes and how you can resolve them.

Your thermostat is on the wrong setting

Check your thermostat to make sure you’re using the right settings. It seems obvious, but it can be easy to overlook or accidentally select the wrong option. Your thermostat should be set to “cool”, and your fan should be set to “auto,” not “on.”

If your fan is set to “on,” it will be blowing air through your home constantly, even when your AC is not producing cool air. Changing your setting to “auto” means the fan will only blow air through your registers when your AC is actively cooling your house, preventing warm air from being circulated.

Your refrigerant is leaking

One of the most common causes of warm air blowing from your AC is low refrigerant. Refrigerant cycles through your indoor and outdoor AC unit, absorbing the heat from inside your home and expelling it outside.

Your refrigerant lines are a closed system, so a low level of refrigerant indicates that there is likely a leak somewhere in your unit. If your evaporator coils are frozen over, but your AC is producing only warm air, that is a good sign there is a leak. Since refrigerant is a dangerous chemical, do not attempt to fix the leak on your own. Instead, reach out to a trusted HVAC professional to resolve the problem.

Your evaporator or condenser coils are dirty

Your system’s evaporator coils, on your indoor unit, and condenser coils, on your outdoor unit, can become dirty and clogged. Your outdoor unit is especially vulnerable to clogs due to outside dirt and debris. When that happens, air cannot flow freely through your system or effectively cool your house.

Regular maintenance checks are the key to keeping your AC coils clean and working properly. A professional technician can get rid of any dirt or grime that may be affecting your system’s performance. In addition, make sure to keep the area around your outdoor unit clean and tidy to prevent debris like leaves or grass from getting into your system and causing blockages.

Your air filter is clogged

A dirty or clogged air filter may not directly cause warm air to blow through your home, but it can lead to clogged coils. As mentioned above, if your system’s coils are blocked, air cannot flow properly through your unit to cool your home.

Checking your air filter regularly, at least every 30-90 days, is essential to keep your AC in good working condition. Regular filter replacements not only prevent your coils from clogging but help keep your indoor air quality (IAQ) levels high.

Your compressor is faulty

The compressor is one of the most critical elements of your AC unit. It helps move the air through your system and keeps it running efficiently. It turns refrigerant from a low-pressure gas to a high-pressure, high-temperature gas to release the heat it has absorbed from inside your home to the outdoors.

The older your AC unit, the harder your compressor must work to function properly. Over time, this increasing strain could trip your breaker and cause your AC to blow warm air. Blockages due to rust or other contaminants can also occur. Since compressor issues can be challenging to diagnose, enlist a professional to inspect your unit if you suspect your compressor has a problem.

5 Reasons to Clean Your AC Condenser This Summer

Your air conditioner’s condenser is a vital component of your AC unit. Keeping it clean and free of debris is essential to ensuring your AC is working properly and maintaining a comfortable temperature inside your home.

As spring turns into summer and your AC usage increases, it’s important to check your condenser for dirt and debris. Around this time, leaves and other plant debris, particularly cottonwood, begin to blow through the air and clog up your system. This can reduce your AC’s efficiency, increasing energy bills and potentially causing lasting damage to your unit.

Cleaning your condenser is a painless way to prepare your system for effectively running all season long. A clean condenser helps your AC stay energy-efficient and can save you money in the process.

What is an AC condenser?

The condenser is the outdoor unit of your air conditioning system. It is the part of your system that transfers indoor heat to the outside, or vice versa, depending on the time of year. During the summer, the condenser coil collects the heat from the inside of your home and expels it outdoors to keep your house cool.

Why should I have my condenser cleaned?

1. It optimizes your AC’s performance.

If your AC condenser is dirty, it must work harder to effectively cool your home. Heat can become trapped in the condenser coil, which reduces your energy efficiency and makes it more difficult to keep your home at a comfortable temperature. Cleaning your condenser allows your system to maximize its performance.

2. It reduces your energy costs.

An inefficient system can cause your energy bill to inflate. Your AC unit has to put in more effort when your condenser is dirty, and that leads to higher usage and costs. Once your condenser is free from dirt and debris, your energy bills will likely decrease.

3. It keeps your system in good shape.

Enlisting a professional to clean your condenser not only maximizes your system’s performance but also prevents frustrating, costly breakdowns. Debris that gets trapped in your machine can wear down your system or cause lasting damage, resulting in costly repairs or replacements. Regular cleaning of your condenser helps keep your unit in good condition over the long haul and extends the lifespan of your system.

4. It improves your indoor air quality.

When dirt and grime get trapped in your condenser, it can lead to the growth of mold, bacteria, and other toxins. Once they’re in your outdoor unit, they can move to the inside of your house and contaminate your indoor air, potentially causing health problems. By cleaning your condenser, you are preventing those harmful contaminants from entering your home.

5. It keeps you and your family comfortable.

Your family’s comfort in the summer months is a top priority. Without proper cleaning, you risk potential system damage or breakdowns. This can result in uncomfortable and potentially unsafe indoor temperatures in addition to poor air quality. Getting your condenser cleaned will help make sure that your family is comfortable all summer long.

How can I get my condenser cleaned?

While it is possible to do it yourself, we do not advise that you clean your condenser on your own. Due to safety concerns, we strongly recommend that you reach out to a professional. A professional HVAC company has the knowledge, skills, and techniques to clean your condenser efficiently and safely.

However, we do suggest that you clean the area surrounding your outdoor unit regularly to minimize the amount of dirt and debris trapped in your system. Clearing out debris around the unit reduces the risk of dirt, plant matter, or other debris getting stuck in the coils and causing damage.

Routine maintenance and cleaning are the keys to keeping your HVAC system in the best possible condition. Whether you simply need your condenser cleaned for better performance or your AC unit has completely broken down, Hauck Bros. can help. We offer residential and commercial maintenance services and plans to ensure your system is working optimally. Fill out our simple online form to contact us today!

How to Clean Your Air Conditioning Vents

As the cooler weather transitions into the warmer months, you’re likely getting ready to turn on your air conditioner for the first time in a while. Since it probably hasn’t seen much action recently, it’s the perfect chance to do a deep cleaning of your supply and return vents.

The supply vents are typically covered with registers that can be controlled by an adjustable damper.  These are usually rolling lever-type guides, or levers on the side of the vent, that open and close the damper to manage supply air flow from the supply ducts.  You do not want to close these completely, or the system may become unbalanced.

The return vents are covered with grilles, which are permanent metal coverings.  They are found in walls, ceilings, and floors.

Your vents can harbor a lot of hidden dirt and lint. By ensuring your AC unit and vents are clean from dust, allergens, indoor chemicals, and other debris, you can keep your indoor air quality levels high. This helps you and your family stay healthy and breathe crisp, clean air through the warm seasons.

Luckily, cleaning your vents is a simple and straightforward process. Ready to start? Follow these steps below.

Cleaning Your AC Vents

  1. Turn off your unit

Make sure your HVAC unit is turned off before you begin any cleaning. Both the furnace and the air conditioner should be off for safety purposes. We also recommend wearing a mask throughout the process to prevent breathing in dust and other particles as you work.

  1. Remove registers and grilles

In order to remove your air registers and grilles, you may need to use a screwdriver. If required, unscrew them, and then remove them from the walls or ceiling.

If they are high up on the ceiling and can’t be easily unscrewed, use a duster or a broom to reach them and remove as much dust and debris as possible.

  1. Dust off registers and grilles

Once the registers and grilles have been removed, use a duster, cleaning brush, or towel to get as much dirt off as possible. To prevent dust from dispersing into the air and recirculating, dust off the registers and grilles directly into a garbage bag.

  1. Wash with soap and water

After dusting, use a damp cloth to carefully wash them with soap and water. This helps to remove tougher grime, dirt, and particles clinging to your registers and grilles. Let them air dry completely after they’ve been washed.

  1. Replace registers and grilles

When the registers and grilles have fully dried, screw them in place if needed.

  1. Change your air filter

If you’re like most people, chances are, you’re overdue for an air filter replacement. The frequency that you change your filter varies depending on your usage and the type of filter you use, but if you’re just starting to use your AC again after winter, it’s likely time to switch yours out.

A clean filter will help keep your HVAC system in top shape and reduce the amount of debris clogging up your vents and ducts.

  1. Turn on your AC

Now that everything has been cleaned and your filter has been replaced, it’s time to turn on your AC.

Even if it’s not quite the appropriate weather for air conditioning, a quick test of your system to ensure it’s running properly is a good idea at this point. In case your system is having any issues, you have time to schedule a maintenance appointment before the hot weather starts to hit.

Spring HVAC Maintenance Checklist

Spring HVAC Checklist

By Air Conditioning, Heating, Home Automation, Indoor Air Quality, Maintenance, Residential, Thermostats

7-Point Spring Checklist for Your HVAC System

With the beginning of spring on the horizon, there’s no better time to check on the state of your HVAC system. After a long, harsh winter that can put stress on your equipment, a good spring cleaning and maintenance check is the perfect way to make sure your system is ready for the warmer spring months.

Ready to start cleaning? Check out these 8 tips to prepare your home for spring.

  1. Change your air filter

If you haven’t changed your air filter in a while, make it a priority for spring. A dirty air filter can spread dust, dander, and bacteria throughout your house, causing health problems like asthma and allergies.

Additionally, a clogged filter restricts airflow, meaning your HVAC system has to work harder to heat and cool your house. Check and replace your filter to increase your energy efficiency and start circulating clean, breathable air in your home.

  1. Clean your air vents

Your air vents accumulate dust, pet hair, mold, and other debris, especially during winter. Remove the vents on your floor and ceiling with a screwdriver and use a vacuum to clean out the dirt.

Then, wash your vents with soap and water and let them air dry before replacing them. This helps to ensure that the dust and dirt on your vents don’t get blown around when it’s time to turn on the AC.

  1. Dust your ceiling fans

The blades of your ceiling fans are another place where dust and hair tend to collect. Since you don’t want that dirt to fling around the room once you turn them on, make sure to dust and wash your fans’ blades.

Use a ladder to reach all surfaces and a cloth or sponge to gently wash each blade. Just don’t turn the fan on before the blades dry – dust clings to damp blades.

  1. Install an air purifier

Spring is an ideal time of the year to install an air purifier. Air purifiers like ionizers can eliminate germs, mold, and allergens that have been lingering in your home all winter.

They also help to neutralize odors, get rid of harmful indoor chemicals, and improve your sleep. Air purifiers have even been shown to increase life expectancy by improving indoor air quality.

  1. Test and clean your air conditioner

As the weather gets warmer and you switch to using your AC, run a quick test to ensure it’s working properly. You don’t want to end up on a 90+ degree day with a broken or inefficient AC unit.

Also, make sure to clean the area around your unit outside. Debris like leaves, shrubs, and grime can accumulate and block airflow. There should be two feet of clear space around your unit for it to function properly, so remove any weeds and trim shrubs in the area. Clean the coils and the condenser with a soft-brush vacuum and a hose to wash away dirt. Once it’s completely dry, you can turn on the power.

  1. Upgrade to a smart thermostat

If you haven’t already changed to a smart thermostat, this spring is a great opportunity to make the switch. Smart thermostats can save you up to 20% a year on energy costs, so you’ll likely lower your AC bill after it’s installed. With the current rising prices on gas, food, and more, every bit of savings counts.

Plus, with a smart thermostat, you can adjust your home’s temperature from anywhere, anytime, from your smartphone. On a transitional spring day, you can turn off the heat and turn up the AC, all while you’re at work. When you get home, your house will be comfortable and cool.

  1. Schedule a maintenance appointment

Regular professional maintenance is essential to keeping your HVAC system running smoothly throughout the year. By scheduling a maintenance appointment for the spring, you can avoid the risk of working your system too hard once the hot weather hits.

Preventive maintenance can help keep your home’s air clean, lower utility and repair costs, extend the life of your equipment, and improve your home’s overall comfort. Reach out to our skilled technicians at Hauck Bros. to schedule your maintenance services today!

Packaged Rooftop Units

By Air Conditioning, Commercial, Heating

How It Works

For Commercial applications, Packaged Rooftop Units are installed on the roof of the building or they can be installed on a slab at ground level. Unlike a split system where there is an outside and indoor part to the HVAC system, Packaged Rooftop Units have all the components built into the unit. They are made to withstand the Miami Valley typical weather of rain, sun, frost, wind, heat, and other conditions. They provide commercial buildings space saving options since the unit doesn’t need an indoor unit. Depending on the older unit a curb adapter may be needed for the new unit to install correctly.
Air enters the unit via the air hood on the side, it passes through dampers on the inside that regulates the airflow, and than the air goes through the systems air filtration. Next, the air is either heated or cooled (depending on the system configuration and the current operating mode) and circulates through the ductwork inside the building.

Air Conditioners

By Air Conditioning

When properly installed, a central air conditioner can provide efficient cooling for your home or business. Seasonal Energy Efficiency Ratio (SEER) is the rating of the unit in terms of the cooling output during a typical cooling season divided by the total electrical energy input during that same period. In other words, the higher the rating, the more efficient the unit is and the more money you can save in utility bills. Air conditioners that are 16 SEER and above may be Energy Star Qualified and may qualify for rebates from your utility company.

Estimated Cooling Energy Saving, Based on 9 SEER 3 Ton Unit,
Unit New Unit SEER Estimated Saving for 15 Years
Bryant® Legacy™ 13 $2,300+
Bryant® Legacy™ 16 $3,250+
Bryant® Preferred™ 17 $3,500+
Bryant® Evolution® 18 $3,750+
Bryant® Evolution® 20.5 $4,100+

Saving energy not only helps keep your utility bills down, it also helps avoid costly upgrades and new buildings to produce energy. By not building new power plants, power lines, substations, and transformers, the cost of running electricity is kept lower for everyone. One of the biggest opportunities to save money is in making sure that when you are not at your home or business that you set the temperature to a higher setting. The easiest way to accomplish this it to have a programmable thermostat. If you have a normal schedule throughout the week, a programmable thermostat can be an easy answer to help you save money. A Wi-Fi thermostat give the additional benefit of being able to access on your smart device to easily adjust the temperature from almost anywhere.

Make sure to protect your equipment during the colder fall, winter and spring months with an air conditioning cover. We offer models made by Innerflow® for Bryant® equipment specifically designed to cover the air conditioner from top to bottom but still allows condensation to escape. These covers come with a ten-year warranty and protect your unit from debris, harsh weather, ultraviolet rays, ice, and rain.

Air Conditioning - How Does it Work?

Air Conditioning – How does it work?

By Air Conditioning, Commercial, Cooling, Residential

During the Summer in the Miami Valley, air conditioners get used a lot. According to U.S. Climate Data, from May 29th to Sept 18th, our average high is over 75°F. That’s 113 straight potential days of Air Conditioning use.  Then of course, there is the summer high humidity. Humidity levels of 60% or higher can lead to adverse health effects – Bacteria, Viruses, Mold, Fungi, Mites, Asthma, and Allergic Rhinitis all thrive in higher humidity. Central air conditioning systems not only take takes away the heat from inside the house, but removes the humidity as well in the heat transfer process. With proper Indoor Air Quality (IAQ) products, Air Filtration, Ultraviolet Lights, Ionizers, and Dehumidifiers, all of these health issues can be addressed as part of your HVAC system.

How it Works

The basic concept of central air conditioning is pretty simple, remove heat and moisture from the interior of an occupied space to improve the comfort level of the occupants. When the thermostat registers that it needs to turn the air conditioning on to maintain the set temperature, the system is turned on or charged. The blower on the furnace turns on and moves air through the duct system and through the filter. This air is blown across the indoor evaporator coil which uses refrigerant to remove heat and humidity. That heat is transferred outside by the lineset and outdoor compressor. A fan on the outdoor unit pulls air over the condenser coils which releases the heat into the outdoor air. The cooled refrigerant then moves back through the lineset to repeat the process until the thermostat temperature is met.

Types

Single Stage
A single stage air conditioner 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 air conditioners always operate at 100% capacity.

Two Stage
More efficient than single stage units, two stage air conditioners 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

Air conditioners play a big role in keeping homes and businesses comfortable during hot days. Being able to lower the temperature inside allows for people to stay cool and comfortable.
The temperature that feels comfortable may be different for everyone. With a variable speed air conditioner, having the air move constantly allows for better dehumidification, better filtration, and lessening of hot and cold spots.  Even with the two speed air conditioner, having the low speed on the majority of the time makes the air feel more comfortable.

Energy Efficiency

If you’re looking at replacing your air conditioner, high efficiency systems can help lower utility bills, be environmentally friendly and maintain your comfort level.  There are also rebates and incentives from some manufacturers and utility companies for higher efficiency air conditioners.

EER (Energy Efficiency Ratio)
EER is calculated by dividing the input electrical power (measured in watts) by the amount of cooling created (measured in British Thermal Units or BTU’s) under a single set of conditions.

SEER (Seasonal Energy Efficiency Rating)
SEER 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 air conditioner’s efficiency could be. Generally, most single stage air conditioners rate from 13 to 19 SEER. Two Stage units rate from 17 to 21. Variable speed units rate from 19 to 26. Comparing against a 10 SEER air conditioner over 15 years*, a 13 SEER could save $1,125, a 16 SEER could save $1,830, a 20 SEER could save $2,430, and a 25 SEER could save $2,835.
*based on 2016 US National Average

Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency. By choosing ENERGY STAR certified heating and cooling equipment and taking steps to optimize its performance, you can enhance the comfort of your home while saving energy and cost. Saving energy helps you save money on utility bills and protect our climate by helping prevent harmful carbon pollution and reducing other greenhouse gases. Air Conditioner split systems and packaged units over 15 SEER qualify for ENERGY STAR.

DIY

Just like your car, your air conditioner needs maintenance at least once a year to keep operating as efficiently as possible to provide the comfort you and your family deserve.  Things you can do yourself include:

  • Replace or clean your air filters regularly – this lowers your unit’s energy consumption by at least 5%.
  • Clean the evaporator coil as needed, typically once a year.
  • If any coil fins are bent, you can straighten them with a “fin comb.”
  • Clean debris from the fan, compressor and condenser of your split system.
  • Prevent drain clogs in your unit by passing a stiff wire through the channels once in a while.
  • Inspect the window seals around your window unit to make sure air is not escaping.
  • Be sure your thermostat is set properly.
  • Make sure the drain isn’t clogged and that the filter isn’t dirty.

Air Conditioning Accessories – Part 2

By Air Conditioning, Cooling, Residential

Last week, we talked about a few accessories to help keep your air conditioning unit running optimally during the summer months. Here are a few more!

Cover

How it works – Air conditioners are covered during the fall, winter, and spring to protect from the elements and the environment/ Harsh weather, ultraviolet rays, flying debris, ice, and snow.

Features – Protects unit from top to bottom, removes damaging condensation, anti cold cracking material, uv protected, fire retardant, mildew and fungus free, 10 warranty

Condensate pump

How it works –  In HVAC or refrigeration process, the water that condensate need to be channeled out from the building to proper drainage outside the building. The condensation process usually occurred when the air passes though the cold evaporator coil during the cooling process. As a result, the moisture that accumulate on the coil then drip down into the drain pan that is placed underneath the coils. Systems that are able to use the gravitational force to flow the water that accumulate on the drain pan does not require the use of the pump. However, there are many instances when the air conditioning systems require to use of this pump to get the water out to prevent the water from dripping into the space.

Hard start kit

How it works – Is an electrical component that is attached to the condensing unit of the air conditioner. This device allows the compressor to start up quickly and use less power during the process. It ultimately lets you save money on your energy bill. A hard start kit is a combination of a relay and a start capacitor. When the air conditioner starts up, the relay is on. This means that the energy being stored in the capacitor is being used to power the compressor. The relay then reads the electrical current from the compressor and upon arriving at a certain level or when the compressor is fully running, the relay is turned off or rendered out of the circuit. This action renders the start capacitor no longer needed to aid the compressor.

Air conditioning units do a great job of keeping your home comfortable, but they need a little TLC too.  Below are some accessories to keep your unit running optimally all summer.

Pads

The air conditioning condenser vibrates with continual use on the same surface over a period of time, it can sink into the ground or cause damage to the unit. That is why everyone needs a good AC condenser pad to help support and contain the unit over time This expensive piece of equipment needs to be properly supported. To help the unit survive harsh winters or summers a quality waterproof pad is essential. Condensers also accumulate water as it does its job making them weigh even more. This can put significant strain on the lines and tubes that run underneath the unit. It is crucial that the unit stay dry as well as level to extend the equipment’s lifespan and functionality.

Types of Pads

Hauck Brothers offers concrete or composite pads. Units installed on concrete pads are solidly anchored on a waterproof base. Water drains easily through vents on the bottom of the unit. Early condensers were installed on several inches of concrete to support their large size. Cement is still a favorite pad for large-capacity units. Composite , As units decreased in size, new materials were developed using green materials. These pads are inexpensive enough that homeowners can purchase new bases when new units are installed. Newer pads, formed of recycled plastic formed into pads sized to fit standard bases, are UV stable, rendering them impervious to sunlight and rain that turn most plastics brittle. Engineered, ribbed surfaces, distribute weight and cushion against vibration.

Sound blanket

While air conditioners and heat pumps may be ideal for cleaning the air in our houses and cooling or heating it, some compressors are extremely noisy. If your compressor is waking you in the middle of the night when it comes on, there is a way to reduce that noise up to 40 percent or more. Installing a compressor sound blanket can be a quick solution for air conditioner and heat pump compressors that have an unacceptable noise level. These blankets do not diminish compressor effectiveness or harm them in any way.

High and Low Pressure Switches

The high-pressure switch will kill the compressor circuit if the pressure exceeds the rating on the pressure switch. The ratings will vary depending on the type of refrigerant the air conditioner or heat pump uses the system. The low-pressure switch is typically an automatic reset switch that will reset itself when the pressure on the low-pressure side of the refrigeration systems returns to normal or above the setting on the switch. When a refrigeration system operates at lower than normal pressures the system can freeze up with the freezing beginning at the evaporator coil and working its way back to the compressor via the suction line. Freezing of the refrigeration system is bad and lead to liquid refrigerant slugging in the compressor which can lead to compressor failure.
