Your Show Low 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 Navajo 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 Show Low'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.
In Show Low, AC is a life-safety system during peak summer. Navajo County temperatures regularly push equipment to its design limits — making pre-season refrigerant checks, capacitor testing, and coil cleaning the difference between a system that lasts 14 years and one that fails at year 9.
With an estimated 3,310 annual cooling degree days and roughly 88 days exceeding 90°F, Show Low's climate places above-average demand on residential AC systems. Navajo County's population of 12,102 includes many homes with equipment installed during the region's growth years — systems now in the replacement planning window.
