Statewide HVAC context
How Arizona’s climate affects comfort
Cooling is the dominant demand in most of Arizona, where air conditioners and heat pumps run for many months under extreme heat. Systems work hard against high temperatures, dust, and dry air, which can accelerate wear on compressors and coils. Heating needs are generally light in the lower deserts but more noticeable at elevation.
