Your Superior Heating and Cooling Experts
The federal minimum efficiency standards for new AC equipment changed in 2023, and they vary by region. Arizona falls in the southern efficiency region, meaning new AC installations in Pinal County must meet the 15 SEER2 minimum — not the 14 SEER2 that applies in northern states. Higher-efficiency equipment costs more upfront but reduces operating costs over the system's life. In Superior's climate with its extended cooling season, the payback on higher SEER2 equipment comes faster than it would in a market with a shorter AC season.
Desert heat in Pinal 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.
Superior averages approximately 3,740 cooling degree days annually and sees around 104 days above 90°F each summer. The median home in Pinal County was built around 1989, meaning a substantial share of local air conditioning systems are approaching or past their typical 12 to 18 year service life.
