Your definition of “comfort” may be different from your
neighbor’s, and understanding some key terms can help make your
search for improved heating and air conditioning efficiency and
performance less confusing…and more effective. Advanced
Reciprocating Compressor – a type of compressor that uses a more
efficient process for compressing refrigerant for better cooling
efficiency. AFUE – (Annual Fuel Utilization Efficiency) tells
how much energy is being converted to heat. For example, an AFUE
of 90 means that 90% of the fuel is being used to warm your
home, while the other 10% escapes as exhaust with the combustion
gases. Air Handler – is a device used to condition and circulate
air as part of a heating, ventilating, and air–conditioning
(HVAC) system. An air handler is usually a large unit that
resembles a furnace, runs off electric and is usually used
residentially with Heat Pumps. BTU – (BritishThermal Unit) Used
for both heating and cooling, BTU is a measure of the heat given
off when fuel is combusted. Or
