Updating Your HVAC Unit

Understanding An Air-Source Heat Pump

When you are looking for equipment to condition the air in your home, you might think that you need an AC unit to cool your home and a separate furnace or heater to heat your home. This is not always the case. In some cases, you may be able to utilize one piece of equipment and get all the benefit that you need. The key is to match your equipment to the climate that you live in. In moderate climates, the only piece of heating and cooling equipment that you need is a heat pump.

What is a Heat Pump?

An AC unit cools a home by pushing the hot air from your home over a set of evaporator coils. The hot air flowing over the coils forces the coolant flowing through them to vaporize, and as it does, it absorbs heat from the air. The heated coolant then flows to a set of condenser coils on the outside of your home. These coils expel the heat from the coolant. The net effect of this process is that the air in your home cools down. A heat pump reverses this process so that the coolant absorbs heat from the air outside of your home and expels it inside your home, thus warming your house. 

The Advantage of a Heat Pump

Using a heat pump helps because the cost of one heat pump will be less than the combined cost of an AC unit and a furnace. When you install only one piece of equipment, you save on installation and maintenance costs. 

Limitations of a Heat Pump

Using a heat pump can be an effective solution for maintaining a comfortable temperature inside of you home, but only if the climate cooperates. The closer the temperature gets to freezing, the less effective a heat pump is. If the temperature dips below freezing, a heat pump may struggle to heat your home at all. Thus, in cold climates, a heat pump may be a good choice for maintaining the temperature in your home during three out of four seasons. However, if you live in a moderate climate, where you rarely if ever have to worry about subzero temperatures, then you should be just fine with a heat pump.

When you are choosing heating and cooling equipment for your home, it is important to know what your options are. If you are looking to save a little bit of money, you should at least ask if a heat pump could work in your home.
