Why does it cost so much to run an Air Conditioning system?

Submitted by admin on

Air conditioners run on electricity, and electricity is the most expensive energy source. Converting fuels like coal or natural gas into electricity is inherently inefficient. What’s more, much of the original electricity generated at the power plant is lost during transmission over power lines. So, according to the U.S. Department of Energy, by the time it reaches your home, electricity is only 33% efficient on average.

The good news today is that air conditioning systems are much more energy-efficient than they once were, and things are improving all the time. Another important factor is design—if your AC system is not carefully planned to meet the cooling needs of your home, it will run less efficiently than it should. Princeton Air takes great care in evaluating and designing efficient systems, and we can recommend high-efficiency equipment from quality manufacturers like American Standard.
