Forced Air Heating Systems
Editor In Chief, United Home Improvement
Forced-air heating systems are the most commonly used central
heating units used by American homes. They operate by a main furnace
that draws in the air from rooms through ductwork. The furnace then
filters and heats the air. This heated air is circulated back into
the rooms, rising to higher levels and producing warmth.
One of the first things you should consider when purchasing a new
furnace is the efficiency level. This is indicated by the AFUE
rating. The higher the AFUE percentage, the better the unit is. The
benefit to having a higher efficiency rating on your furnace is that
it takes less gas to produce the same amount of heat, therefore,
saving you money.
Forced air heating systems come in several different sizes. You can
select between “up flow” “down flow” and “horizontal” models. Also,
keep in mind that proper installation is extremely important to the
prolonged existence and performance of your new furnace. It is said
that proper installation, efficiency, sizing, and a reputable
contractor are much more important than the brand you choose.
Common problems include, impurities of furnace air supply, burnout
gases contaminating the fire zone, old furnace filters, and possible
power control issues. If you find yourself having similar
difficulties with your furnace, it is in your best interest to hire
a professional technician to come in and take a look at things.
