When it comes to heating and cooling equipment, numerous people are confused by the many options available. Whether you are having your unit repaired or need to replace it, knowing the variations between your alternatives can help you make more knowledgeable decisions. Heat pumps and air conditioners each have their own characteristics, and deciding on the best one to have put in will depend on your climate and how you heat and cool your home.
Throughout the summer, air conditioners and heat pumps work the same. Refrigerant in a cold, liquid state moves through the evaporator coil. The unit?s blower blows air past the coils, chilling the air. The coils then soak up heat from the home and the refrigerant inside expands into a gas. This gas moves outside to the condenser where the refrigerant loses its heat as a fan blows over the coils. The refrigerant then moves into a compressor to be compressed back into a cold, liquid condition to move back into the home?s evaporator coils and repeat the procedure.
In the wintertime, heat pumps turn this cooling method backwards. So instead of drawing heat from the home and expelling it outside, heat from the outside is pumped into the dwelling. These are commonly not very effective if you live in an area where it generally freezes in the winter, but for mild areas in the South with typical winter lows around 45 degrees Fahrenheit, this equipment works well for warming a house.
If you have an air conditioning system set up, you will still need another heating unit to keep you warm throughout the winter season. If you have an existing furnace that continuously needs repair, look at a heat pump to replace it and your A/C system if you dwell in an area with a mild winter climate. Talk to your HVAC service technician to determine if you require a new heating or cooling device, and what your best alternatives are.
Keeping your home warm in the winter season and cool in the summer time is a matter of having the proper equipment for the job. Your decision to have either a heat pump to heat your home or an air conditioner and auxiliary furnace will establish how comfortable your home is all through the year.
