Where does the heat go?

Heat pumps are generally found in warm and mild climates such as the ones we enjoy here in Florida. The systems work pretty efficiently in regions which rarely endure temperatures below 40 degrees or so. It is highly likely that you currently have a heat pump system installed in your home. Your Blue Bear Tallahassee Home Inspector is certified and trained to inspect heat pump systems. 

The units generally consist of two parts. One is found outside and is commonly referred to as the compressor or condensing unit. The other unit is generally found in the center of the home in a closet or in the attic. This unit is often called the central unit. 

The heat pump in your home works much like your refrigerator and your vehicles air conditioner. The system uses refrigerant which boils at very low temperatures. The refrigerant flows through the line as either a gas or liquid. 

The compressor (outside), compresses the gas and then condenses (cools) it before sending it back to the central unit. The central unit pulls air from inside the home, through the air filter, and over the refrigerant line. The heat in the air is absorbed by the liquid as it boils, and the refrigerant becomes a gas again which is sent back to the compressor to be condensed. The cycle is repeated until the thermostat is satisfied and the air in the home is cooled.

Basically speaking - the heat in the air inside the home is absorbed into the refrigerant and then exhausted outside - cooler air remains in its place. The process is reversed during the winter season. The heat in the outside air (yes there is still heat in 50 degree air) is brought inside and the cooler air is exhausted outside the home. 

One of the most important things you can do to extend the service life of your heat pump system is to change the filter regularly. Your Blue Bear Tallahassee Home Inspector will gladly answer all of your questions regarding heat pumps and HVAC. Contact Blue Bear today.
