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!

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.

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.

I had an amazing experience here at B & M! Both my mom and I had been having problems with our Toyota Priuses, this is the closest shop that works with hybrids but unfortunately we live about an hour and 15 minutes away. Boy am I glad that we drove this whole way! We arrived there as they opened and told them about the cars problems and stayed to chat for a while. Marty, the main mechanic mentioned how they had been operating with just two employees and the manager because everyone else had quit. Because of that they were unsure how soon they could get to my car. I wasn't super happy about that but I understood that it was out of their control. Because I was trying to leave shortly for the start of school, I really didn't have much time to waste, but again, they couldn't do much about it. My mom and I had about a days worth of errands to run around Knoxville so we told Marty that we would be around for that day in case they miraculously finished with the car. About an hour or two before they closed we got a call about the car. Unfortunately, my car was totaled, but because they were so fast with their diagnosis I still have plenty of time to figure out what to do as far as school goes. I would highly recommend coming here for your auto repairs. They were very considerate to my need for quickness even through their rough times, they were all very personable and I really enjoyed standing there listening to them talk, and so if ever I come back after college, they have gained themselves a customer for life. Thank you so very much Marty, Bob, and Gary.

I had them do some repairs on a somewhat Frankenstein VW trike I just acquired. They did a FANTASTIC job figuring out what I had and then getting it road ready. A special thanks to Diego. Dude, you are my go-to guy for anything I need on this trike. Awesome people and awesome service.
