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 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.
WHAT IS THE BEST TYPE OF HEAT PUMP FOR YOU?
- 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.
- 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 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.
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.
These features in different models add benefits beyond comfort, energy efficiency, and humidity control.
- Covers more of the surface of the outside unit protecting the coils from damage
Baked-on Powder Paint
- Makes the surfaces more resistant to chipping, scratching, fading, and wearing than other finishes
High and Low Pressure Switches
- Monitors the pressure of refrigerant, will automatically turn off compressor to prevent damage if there is a problem.
Forward-swept Condenser Fan Blade
- Helps improve the effectiveness of the fan while keeping noise down
Compressor Sound Hood
- Helps reduce noise
Energy Tracking, with Qualified Controller
- Based on your energy costs, maintains a log of energy use for that system.
Enhanced Diagnostics, with Qualified Controller
- Notifies servicer of problems, high and low humidity, and service reminders
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 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.
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.
- If your unit needs more than this basic maintenance, be sure to contact the professionals!
Benefits of Maintenance
- Prolongs equipment efficiency
- Promotes healthy clean air
- Supports lower utility costs
- Guards against unexpected failures
- Prolongs equipment life
- Keeps your equipment warranty valid
UNIT NOT WORKING PROPERLY?
These are some common issues we run into:
- Refrigerant could be low or leaking. Give us a call at 937-325-0636 to give your system a recharge and/or repair the leak.
- Unit not turning on? Check the thermostat batteries or contact us to check the electrical connections.
- Is the airflow not as strong as it should be? Check the filter or contact us to check your ducts for leaks, and to clean and seal them.
- Reduces compressor noise from air conditioners or heat pumps.
- Concrete or plastic, designed to keep outdoor unit off the ground and level.
- Unit optimized for removing humidity at a much higher rate than Air Conditioner
- Carries the refrigerant from the coil in the outdoor unit to the coil in the indoor unit.
Line Set Cover
- Protects the line set from damage by Ultraviolet light, weather, and other sources.
- Unit that monitors and controls your HVAC system products.
Air Filtration and Purification
- Cleans and purifies the air by removing allergens, odors, bacteria, viruses, dust, pollutants, fungus, and other airborne contaminates.
- Removes condensation by way of a pump.
- Monitor and control aspects of your home from virtually anywhere.
- Protect vital and expensive air conditioning system components from out-of-warranty coverage caused by power quality issues, such as brownouts, surges and short cycles with a comprehensive solution.
Water Leak and Freeze Detector
- Placed by water heater, condensate pump or drains, gives early warning of problem.
High and Low Pressure Switches
- Safeties installed on units to protect the unit, compressor, and anyone working on the unit.
- Part of a split-system air conditioner or heat pump located indoors. The evaporator coil cools and dehumidifies the air by converting liquid refrigerant into a gas (or vice-versa). A blower moter, typically in a furnace, then moves air over the coil to either heat or cool your home.
