Get Your Car's AC Compressor Repaired

Kar Tech

At Kar Tech we know each component of your car's AC has a specific function. A cracked or damaged compressor can cause your car air conditioning to fail. Call today at 636-441-8121 and talk to one of our pro mechanics about repairing your car's AC compressor.

Replacing Your Car's AC Compressor

At Kar Tech we recommended that car owners replace the complete AC compressor assembly because the compressor replacement core operates under extreme physical pressure. The compressor is powered by a serpentine belt, which provides the energy needed to compress freon refrigerant to cool the car's cabin. Once compressed, the freon is in a volatile, high-pressure state. This pressure forces the liquid out of the compressor and through the cooling system.

What To Expect When Kar Tech In Saint Charles Replaces Your AC Compressor
  • Kar Tech uses AC compressors that are durability-tested for high heat conditions.
  • We use a replacement kit assembly designed to meet or exceed OE function. It includes car AC compressor, accumulator and any needed expansion devices.
  • We use kits with a "Rapid Seal" designed specifically for your compressor. Kar Tech's pro mechanics know that even the smallest gaps can cause serious damage to your car's cooling system and engine.

Always good work and fair prices. I have a Tahoe that I purchased new that now has 340,000 miles, and a bunch of Jeeps with 240,000 miles apiece, I credit Kar Tech for giving me the ability to keep my autos on the road so long.
