Local HVAC Service - Shongopovi, Arizona
If your energy bills in Shongopovi 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 Navajo 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 Navajo 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.
Shongopovi averages approximately 3,510 cooling degree days annually and sees around 107 days above 90°F each summer. The median home in Navajo 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.
