Five Signs Your Car AC Needs To Be Serviced?

  • Your car air conditioning blows only slightly cooler than the outside air.
  • Your car's air conditioner blows air that smells like mildew and mold.
  • Your A/C only works while driving.
  • You have low airflow even at the highest fan setting.
  • Water condensing or dripping on your foot while driving.

Don't wait! If your car's A/C is working at reduced efficiency, it's worth a visit to B & M Automotive & Diesel Service. Taking care of regular maintenance now can help you avoid more expensive AC repair costs down the road. Sometimes fixing a broken air conditioner is as simple and cost effective as adding new coolant.

Most truck and car air conditioning systems break eventually with usage. Hoses that feed the AC unit may crack, clog or drip if not serviced. Let us service your car or truck and keep your cooling system performing at its peak. Call us at 865-922-7111 to learn more about how we can get your air conditioning running again!

Common Automotive AC Repair Services

Recharging Your Car's AC
B & M Automotive & Diesel Service in Knoxville for Recharging Your Freon Fast

In some instances when your car's air conditioning (AC) begins to lose its cooling power or fails to blow cool air, it may be time for a simple freon recharge. Recharging your freon is often a fast and inexpensive repair that can help you beat the summer heat. But leaking freon may be caused by a cracked hose or seal. It is often an indicator that a more significant repair is needed.

Repair Your Car's AC Compressor
Let B & M Automotive & Diesel Service Repair Your Car's AC Compressor

The cool air in your car is produced primarily by the compressor. The four main functions that your vehicle's compressor carries out include pressurizing the refrigerant to cool cabin air, monitoring and controlling temperature output, sensing temperature changes inside and outside the vehicle, and moving air to your car's AC condenser.

Repair Your Car's AC Condenser
Discover the Best AC Condenser Repair in Knoxville

Your vehicle's A/C condenser is usually located in the front of the radiator. When your AC compressor is pressurizing the refrigerant flows to the condenser to reduce the temperature and pressure. The condenser is a vital component in keeping your car's cabin temperature cool. It moves the cooled liquid refrigerant to the receiver/dryer or accumulator.

Highly recommend B&M. They made every effort to fix my Immobilize and ECU. When no one else could or wouldn't take the time to try to fix it. Had issues with the fuel pump and they kept at it until all issues were resolved. Very polite and professional. This place is awesome.

It's hard to find someone to work on Italian cars, and even harder to find someone to do it at a reasonable price, these guys did both! My Little Fiat turbo, runs like a champ! Thx guys!
