What Kind of Heating System Do I Need?

If you are planning to install or replace the heating system in your Carrolton, Georgia home, you may be considering a heat pump, furnace, or a hybrid system. Your main concerns are likely to include, cost, heating system efficiency, value, and how much comfort it provides. Consulting a qualified HVAC contractor is the best way to ensure that the heating system you choose is right for your home.

Heat Pump

Heat pumps absorb heat via the refrigerant. The heat is moved outside and cooler air returned inside. To heat the home, the cycle is reversed. The refrigerant absorbs heat from the air outdoors and moves it inside to heat the home. Heat pumps, which are mostly powered by electricity, are quiet, providing even and comfortable heating and cooling.

Heat pumps produce heating and cooling with the same system, and generally they do so efficiently. They are actually ideal for Georgia’s winters which rarely get to, or below freezing levels. Newer models are more efficient at providing heating for colder temperatures.


Furnaces distribute heated air via a system of ducts. Furnaces are powered by natural gas, oil, or electricity. Furnaces over the last 20 years have become increasingly efficient, with some gas-burning models reaching almost 100 percent efficiency. Gas furnaces, in particular, are known to provide reliable and extremely efficient heating.

Hybrid Systems

The shortcomings of the traditional heat pump in very cold temperatures are overcome by a hybrid system. When the heat pump becomes inefficient due to cold temperatures, the system switches to a gas-powered source of heat, with fuel and component operation automatically adjusted. This type of operation means that you increase energy efficiency by tapping only into the amount of heating energy that is needed at any given time.
