Today’s air conditioner (AC) is based on a prototype invented in 1902 by Willis Carrier, an engineer from Buffalo, New York. Unlike earlier forms of cooling, Carrier’s model controlled the temperature by removing heat and humidity from the air.

When your air conditioner (AC) is running at peak efficiency, you win. Not only will your electric bills in Arizona be cheaper––your AC system will last longer. Plus, your equipment will be operating at its best, so you will experience maximum comfort.

Aside from the professionals, like ours at Reliance Heating & Cooling, who really thinks about air conditioners and their components?

The DOE says air conditioning can account for 35 to 40 percent of your utility bill here in Arizona. We take energy efficiency seriously.

It’s a hot day outdoors, and you are inside your Phoenix home waiting for your air conditioning (AC) system to kick into full gear.

In fact, you can save between 5 and 15 percent of the energy used for your air conditioning by changing your filter in combination with other energy-saving actions.
