Whole-home heating in Arizona
In Arizona, heating systems run for months at a time (IECC zone 5 at the coldest), so weaknesses in ducts and controls cost real money. A leaky duct run in an unheated attic loses the most heat when the attic is coldest, which in Arizona is most of the winter.
Common heating fuels here: electricity, natural gas. Electric baseboard and wall heaters and heat pumps are part of the mix, so breaker, element and line-voltage thermostat problems are common calls.
Desert valleys stay mild, but Flagstaff and the high country see snow and hard freezes. A whole-home check covers the thermostat, the heat source, ducts and returns, so the fix reaches the rooms that are actually cold.
