Car AC Repair in West Valley City, UT

Master AutoTech West Valley diagnoses and repairs car air conditioning for drivers across West Valley City, Kearns and Magna, 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 3500 South with the AC blowing warm. Our shop is on 3500 South between 4000 West and 4400 West, with a waiting room to cool off while we work.

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

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.

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.

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.
