Car AC Repair Services in St. Paul

AC Condenser

The AC condenser converts hot refrigerant gas into a cooler liquid by dissipating heat through its fins and tubes, enabling your car's AC to blow cold air. Our ASE-technicians will inspect for refrigerant leaks, bent fins, debris blockage, and proper airflow to determine if your condenser requires repair or replacement.

AC Compressor

The AC compressor is the heart of your car's air conditioning system, pressurizing refrigerant and circulating it throughout the AC components to enable cooling. We’ll check for unusual noises during operation, test electrical connections, measure pressure readings, examine belt condition, and verify proper clutch engagement to determine if your compressor needs repair or replacement.

AC Diagnostics

Our AC diagnostic service includes checks of the refrigerant levels, compressor performance, electrical connections, condenser, and evaporator. We also perform a complete system pressure test. This is how we identify leads, blockages, or component failures that might be preventing your AC from keeping you cool. All AC repair services begin here.

AC Evaporator

Your car's AC evaporator absorbs cabin heat as refrigerant changes from liquid to gas inside it, creating the cooling effect you feel when your AC runs. Our mechanics will inspect it for leaks, drainage clogs, proper temperature differential, mold growth, and freezing issues to ensure your cooling system keeps you comfortable during Minnesota's hot summers.

Thermal Expansion Valve

The thermal expansion valve regulates refrigerant flow into your evaporator, maintaining optimal cooling efficiency by adjusting to changing temperature demands in your AC system. Our mechanics will test for proper valve operation, check for blockages or freezing, and verify that it's responding correctly to system pressure changes to ensure your AC delivers consistent cooling performance.

We Provide AC Repair for All Makes & Models

Common AC Problems

There are a few common problems that can occur with car air conditioning units. One is that the unit may stop blowing cold air. This could be due to a lack of refrigerant, a blocked filter, or a problem with the compressor.

Another issue is strange noises coming from the unit. These could be caused by loose parts, debris in the unit, or an issue with the compressor.

Finally, the unit may simply not turn on at all. This could be due to a blown fuse or failed relay, an issue with the wiring, or a severely low state of charge.

If you’re experiencing any of these problems, it is best to take your car to a mechanic for diagnosis and repair.
