Desert Home Systems: What Phoenix Heat Does to Houses and How to Answer

The Sun Tax

UV destroys sealant, paint, roofing felt, and plastic fittings years ahead of national schedules. Walk the exterior each fall: caulk joints, paint condition on south and west faces, exposed pipe insulation, and irrigation lines turning brittle above grade.

Tile Roofs: The Underlayment Truth

Concrete tile shrugs off sun for fifty years; the felt beneath it does not. At 20-30 years, underlayment renewal is the real roof job — budget it as a known future and inspect after every monsoon blow for slipped tiles.

AC as Critical Infrastructure

Twice-yearly service, coil cleaning (dust is constant), and honest replace-versus-repair math near year twelve. Duct leaks in 130-degree attics are money pouring into insulation — test them once.

Dust, Filters, and Water

Monthly filter changes during dust season, garage-door seal checks, and water-heater flushing — hard Valley water scales equipment fast. Soft-water systems pay for themselves in appliance lifespans here.
