Master AutoTech Murray diagnoses and repairs car air conditioning for drivers across Murray, Midvale and Cottonwood Heights, from a simple recharge to a new compressor. We find the actual cause before we add refrigerant, and AC repairs are backed by our 12-month / 12,000-mile warranty*.
Utah summers are hot when you’re stuck in traffic on State Street with the AC blowing warm. Our shop is on State Street just south of I-215, with a waiting room to cool off while we work.
Signs You Need AC Repair
A Utah summer is no time to find out your AC is failing. Bring your car in if you notice:
- Air blowing warm or only slightly cool
- Weak airflow from the vents, even on high
- A musty or sour smell when the AC runs
- Clicking, rattling or squealing when the AC turns on
- Water pooling on the passenger floor
- The AC works on the highway but not at idle
- Cooling that fades after a few minutes

Damaged or clogged heat exchangers replaced to restore cold air.
Electrical & controls
Switches, relays, pressure sensors, blend doors and blower motors diagnosed and fixed.
How Much Does AC Repair Cost in Murray?
Car AC repair cost depends on what failed. A system that’s simply low on refrigerant costs far less than one with a leaking evaporator or seized compressor. The main factors are the refrigerant your car uses (newer R-1234yf systems cost more to service than older R-134a systems), how hard the leak is to reach, and whether parts like the compressor, condenser or drier need replacing. We test the system first and give you an estimate before any work starts.
We keep our prices competitive and upfront: you get an estimate and approve it before any work starts.
Need to spread out the cost? Master AutoTech offers several financing options, including the Goodyear Credit Card (6-month special financing on purchases of $250 or more), the Synchrony Car Care credit card, the 1stMILE Mastercard, Snap Finance, Acima, Surepay and RC Willey financing.

What Murray Drivers Say
“These guys are amazing, I went in for a recharge on my A/C and several months later my valves were leaking again, without hesitation they fixed the valves again and fully recharged the system and didnt charge me anything. They are always honest and go above and beyond to make sure all my concerns are addressed.”
Jason Rickard
“These guys are great! They have worked on a few different cars for me and have been really helpful. They try to help you save money rather than squeezing all they can out of you and Steve in the office was great to work with.”
Joe McCann
“My tire was going flat and so I stopped Master Muffler because it was close. The manager, Jacob, made it happen! He checked the air pressure and sprayed the tire. When he couldn’t find a leak, he decided to remove the tire and submerge it – so he could rule that out. He found a big ol’ nail in my tire! He fixed my tire and I was back on the road fast! Thank you Jacob!”

Components of Your Car’s AC System
Knowing the parts makes your estimate easier to understand. A problem with any one of them, or with the switches, relays and wiring that control them, can stop the AC from cooling, which is why we test the whole system first.
- CompressorThe powerhouse. Driven by the serpentine belt, it pressurizes refrigerant and pumps it through the system.
- CondenserA radiator for the refrigerant, in front of the engine radiator. It sheds heat so the gas turns back into liquid, which is why your radiator fan runs with the AC on.
- Receiver-drier or accumulatorFilters debris and moisture out of the refrigerant before they can damage the system.
- Expansion valve or orifice tubeMost cars use one or the other. Both meter refrigerant and drop its pressure so it can expand.
- EvaporatorBehind the dash. Expanding refrigerant absorbs heat from the cabin air, and the blower pushes the cooled air out your vents.
How Often Should You Service Your Car’s AC?
Have the AC checked every one to two years, ideally in spring before the heat arrives. A car AC loses a small amount of refrigerant each year, and dry Utah air, road dust and winter salt are hard on condensers and seals. Run the AC for a few minutes every week, even in winter, to keep seals lubricated.
| Item | Recommended interval |
|---|---|
| AC performance check | Every 1–2 years, before summer |
| Cabin air filter | Every 12,000–15,000 miles |
| Run the AC | A few minutes weekly, year-round |
