About Us.
Arizona Auto Refrigeration has been part of Tucson since 1954. What started as a small specialty shop grew into the city’s most trusted name for automotive air conditioning and heating service. We’ve stayed family owned since 1971, and our commitment has never changed: honest work, reliable results, and treating every customer like they’ve been with us for years.
A Tucson Shop Built on Family, Experience, and Real Automotive Expertise
In the early days of automotive A/C, very few shops understood how to service or repair these systems. We built our reputation by doing the work others couldn’t or wouldn’t. As vehicle technology evolved, so did we. From R12 to 134A to modern 1234YF refrigerants, our team has continued to stay ahead of the curve without losing the hands-on skill that makes a real difference.
What We Specialize In
Automotive A/C and heating systems are complex, and Tucson weather puts them to the test. That’s why we focus our work on:
• A/C diagnostics and full-system repair
• Heater core, blower motor, and valve replacement
• MiST mold treatment
• Hybrid A/C system service
• Commercial fleet and heavy equipment HVAC
• City, state, county, and military vehicle support
We work on everything from daily drivers to RVs, Freightliners, transit vans, shuttles, construction machinery, agricultural equipment, and public service units.

FAQ
-
Why is my A/C blowing warm air?
Most of the time it’s due to low refrigerant, a leak, a failing compressor, or an electrical issue. We diagnose the system and pinpoint the exact cause.
-
How often should I service my vehicle’s A/C system?
In Arizona heat, once a year is recommended to keep pressures correct and catch leaks early.
-
Do you work on hybrid A/C systems?
Not necessarily. It's possible that a section of your roof is loose, or that damage occured in one place only. We'll conduct a thorough investigation before suggesting repair options.
-
Can you service fleets and heavy equipment?
Absolutely. We work on commercial fleets, construction equipment, agricultural machinery, shuttles, and more.
-
Why does my vehicle smell musty when the A/C turns on?
This is usually mold or bacteria inside the HVAC system. Our MiST treatment kills mold on contact and removes odors.
