Heating & air conditioning in Santee, CA
United Home Air runs Santee constantly — a quick fifteen minutes from our Poway shop — so when your AC dies on a 100° afternoon, you're not waiting on a truck from Kearny Mesa.
Hot inland summers, older systems
Santee summers run noticeably hotter than the coast, and much of the housing here — the '70s and '80s tract homes off Mission Gorge and Carlton Hills Blvd, and plenty of newer Fanita Ranch builds — is on its second or third system, often with the original ducts still in the attic. That's why many of our Santee calls that start as "the AC isn't keeping up" end up being airflow and duct problems, not dead compressors. We test instead of guessing, we pull permits with the City of Santee's Building Division, and every changeout gets its HERS duct test. Same crew, a short drive from Poway.
“So glad we found an honest guy. Thank you Johnathan.”
Everything we do, here too
- AC repair — Not cooling, short-cycling, or dead? We diagnose the actual fault and fix it — often same-day.
- AC installation — Right-sized central AC, installed clean, permitted, and HERS-tested.
- Furnace repair — No heat, short cycling, or a burner that won't light — found and fixed, warrantied.
- Furnace installation — Old furnace done? We swap gas or electric furnaces in a day — permit and duct test included.
- Heat pumps — One system that heats and cools, sized for inland summers. Ask us what rebates are actually live.
- Mini-splits — Garages, ADUs, add-ons, and homes without ducts — quiet zoned comfort without tearing walls open.
- Ducts & airflow — Weak airflow, hot rooms, dusty vents — usually the ducts, not the unit. We test, seal, and replace.
- Maintenance — A yearly once-over that catches $80 parts before they become $8,000 summers.
