Forced Air Heating Systems in Greater Gainesville

Diagram of how a forced-air heating system works in a Greater Gainesville home

In a forced-air heating system, air that has been heated by a furnace or heat exchanger is distributed throughout a home's living space by a ductwork system. Supply ducts bring heated air to different rooms; return ducts pull cooled air back to the furnace or heat exchanger to be reheated. Supply and return ducts meet at a central air handler that contains a powerful fan for moving air through the ductwork.

What Does "Efficiency Rating" Mean?

A furnace boiler or water heater burns fuel to generate heat and needs to put that heat into an air stream in your ducts, or into water in your pipes. The efficiency rating is what percentage of that heat gets into your air or water. What happens to the rest of the heat? It goes up the chimney and is lost into the sky. Therefore, a 15-year-old furnace that is 65% efficient is putting 35% of the heat you paid for up the chimney. A 96% efficient furnace only "wastes" 4%! A big difference! And since the cost of the fuel you put through a furnace, boiler or water heater during its lifetime is much greater than the cost of the unit itself, it's worth it to install the very highest efficiency equipment available!

Attic Duct Work

A forced-air heating system can get its supply of heated air from an oil or gas-fired furnace, from a heat pump, or from an oil or gas-fired boiler that circulates hot water through a heating coil installed in an air handler. A forced-air heating system that relies on hot water is called a hydro-air system. During hot weather, the same ductwork system that circulates heated air can also circulate cooled air from a central air conditioner.

Forced-air systems have an equal ability to deliver warm or cool air quickly. But because blowing air can carry dust and other allergens, people who are prone to respiratory ailments can find these systems irritating. Leakage in the ductwork system is another potential problem.

Leaky ductwork is fairly common, and it can substantially reduce the efficiency of both heating and cooling systems, while also introducing unwanted air (from attic and basement or crawl space areas) to interior spaces. Having ducts professionally sealed will solve these problems. Ductwork that runs in unconditioned space (such as a crawl space or attic) should be insulated to limit energy loss.
