What Arizona does to a house
A state is a big place — these are the ranges, not averages. The county pages pin the numbers down.
- Climate
- Zones 6b–10a. Freezing days run from ~4 to ~174 a year depending on the county.
- First freeze
- Usually lands anywhere from October 8 to December 21 depending on the county.
- The air
- Runs from desert-dry to dry, county by county.
- The load
- Split duty: 3 counties lean heating, 10 lean cooling — the county page calls yours.
- Termites
- Moderate pressure as a state band.
- Radon
- EPA Zone 2 — the middle band — statewide. A one-time test settles it either way.
- Labor
- Labor sits near one level statewide — every price band on this site adjusts to the county anyway.
