Local shop. Tucson company. We come to Oro Valley.
Oro Valley sits north of Tucson, still in Pima County. Summer heat does not care about the town line. If the system is down, you want a local crew not a national call center.
We repair the brands we work on: American Standard, Carrier, Lennox, Goodman, Rheem, Trane, and York. Other equipment in the house? Say the name on the outdoor sticker when you call. We will tell you if we can work on it.
No corporate script. Upfront price before we start. Same honest number after hours — we do not add an “emergency” markup.
AC repair when the desert heat is on
For cooling trouble, start here: AC Repair Tucson.
- Blowing warm air
- Strange noises or vibrations
- Unit will not turn on
- Water leaking inside or outside
- Frozen evaporator coil
- Low refrigerant (we find and fix the leak)
If it is a no-cool emergency after hours, call (520) 201-3865. All-HVAC emergency: Emergency Services.

Heating, furnaces, and heat pumps
Oro Valley winters are milder than up north, but a dead furnace on a 30-degree night is still a dead furnace.
- Heating Repair — furnace and heat pump, same-day when we can, 24/7 emergency, no after-hours fee
- Furnace Repair — no heat, short-cycling, noises, igniter / gas valve / blower
- Heat Pump Repair — will not switch heat/cool, lukewarm air, defrost or reversing-valve trouble
