Tucson’s HVAC Heroes. Family-owned since 2006.
Serrano’s Heating & Cooling LLC works Marana. We serve Marana. See Areas We Serve.
We are a Tucson family shop, not a Marana franchise and not a corporate van with a Tucson sticker. When the AC dies on a west-side afternoon, you call the same number everyone else does.

Hours: Mon–Sat 7 a.m.–7 p.m., plus 24/7 emergency.
Northwest of Tucson
Marana is Pima County. It is hot, dusty, and hard on condensers. We serve Marana, we are family-owned since 2006, we are licensed (AZ ROC #221198), and techs are EPA 608 certified.
Brands we work on: American Standard, Carrier, Lennox, Goodman, Rheem, Trane, York. Bring the model off the data plate if you have it.
Air conditioning in Marana heat
https://serranoshvac.com/air-conditioning/
Typical calls: warm air, no start, odd noise, water leak, frozen coil, low refrigerant (leak find-and-fix). Broader repair menu: Repair Services.
If you need a tech after 7 p.m. or on Sunday, that is an emergency call, not a “wait and see” in this climate.
Heating, furnace, and heat pump work
No heat, weak heat, a heat pump stuck in the wrong mode, or a furnace that will not stay lit — call (520) 201-3865. Same pricing after hours. We do not charge extra for nights, weekends, or holidays.
