Serving McNary and Apache County
If your energy bills in McNary have been climbing without a clear explanation, the HVAC system is usually the first place to look. A dirty air filter, fouled evaporator coil, or low refrigerant charge all increase the energy a system draws to produce the same output. A furnace running with a cracked heat exchanger or a partially blocked flue draws more gas to move less heat. In Apache County, where heating and cooling seasons drive utility costs, a 15 to 20 percent unexplained increase in monthly bills is worth an HVAC inspection before assuming the problem is elsewhere.
Desert heat in Apache County puts AC systems under some of the highest sustained loads in the country. Equipment that's undersized, poorly charged, or running with dirty coils fails under extreme ambient temperatures faster than anywhere else in the US.
McNary averages approximately 3,290 cooling degree days annually and sees around 101 days above 90°F each summer. The median home in Apache County was built around 1994, meaning a substantial share of local air conditioning systems are approaching or past their typical 12 to 18 year service life.
