Why homeowners call us back
A neighborhood HVAC company, run the old-fashioned way
Mando Air was started by Rosario Thomas after years of watching neighbors get upsold on equipment they didn't need. The idea was simple: show up when you say you will, explain the problem in plain English, and charge a fair price.
- Flat-rate pricing. You approve the price before we pick up a tool.
- Background-checked technicians with ongoing manufacturer training.
- Clean-home promise. Shoe covers, drop cloths and a tidy workspace.
- 1-year labor warranty on every repair, 10 years on qualifying installs.

Reviews
What our neighbors say
★★★★★
“Our furnace died the Sunday before Thanksgiving. Rosario's tech was in our basement within three hours and had it running again for less than I expected. Honest people.”
★★★★★
“They talked me out of a full replacement and fixed the blower motor instead. That alone earned them a customer for life.”
★★★★★
“Clean install of a Trane heat pump, shoe covers, drop cloths, walked us through the thermostat. Electric bill dropped about 20% the first summer.”
★★★★★
“We use Mando Air for our two restaurant rooftop units. Scheduled maintenance, clear reports, no surprises.”

Seasonal tips
Small habits that keep your system healthy
Change your filter every 1–3 months
A clogged filter is the number one cause of the "my furnace keeps shutting off" calls we get. Write the date on the frame when you swap it.
Keep 2 feet clear around the outdoor unit
Trim shrubs and rake out leaves and cottonwood fluff in spring. Your condenser needs to breathe.
Test your carbon monoxide detectors
Every fall before the first cold snap. If you have a gas furnace, you should have a working CO detector on every floor.
Book a tune-up twice a year
Spring for cooling, fall for heating. Most breakdowns we see could have been caught during a 45-minute maintenance visit.
