Why maintaining your AC System is very important:
Heating and A/C systems may break eventually with usage, hose pipes may clog and drip if not serviced, causing reduced efficiency heating and cooling capabilities. Regular maintenance will keep your AC system operating at peak performance!

Indications your A/C system may be having issues:

  • If your air conditioning blows only slightly cooler air compared to the exterior air
  • Air that blows in smells damp, musty, or like mildew and mold
  • Your cabin does not warm up in cold weather, or is just a little warmer than outside
  • The defroster takes longer than typical to operate, or does not operate
  • Your heater or A/C only functions when driving, not when idling, or quits blowing when the car is stationary
  • Your heating system blows cold air, or the air conditioning blows warm air
  • Low airflow even at the highest fan setting.

A comprehensive evaluation of heating and A/C system includes:

  • Examining the internal controls and blower
  • Checking radiator coolant operating temperature, hoses, pressure radiator cap and thermostat
  • Inspecting the compressor belt
  • Inspecting system and seals for leaks or various other damages.
  • A cooling system pressure test
  • Verifying the A/C pressure meets manufacturer specifications
  • Measuring the interior vent air temperature

Our repair and maintenance services include:

Belts
A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belts will dry out and crack. When you are ready for a replacement you can count on B & M Automotive & Diesel Service for all your vehicle's repair needs.

You not only have to get the belts replaced with quality ones but you should have the work done by experts. To have the belts replaced by auto cooling and heating experts - and get your car driving right - visit B & M Automotive & Diesel Service today. The mechanics at B & M Automotive & Diesel Service will thoroughly inspect your car's belts; replace all worn belts; and adjust the installed belts.

Coolant System Flush
A car's coolant system transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the coolant becomes old and dirty. The old coolant will negatively impact the system's performance. To make sure the system is working effectively, consider having a regular coolant system flush. A coolant flush is basic maintenance for your car's cooling system. Call 865-922-7111 or visit B & M Automotive & Diesel Service in Knoxville, TN 37938 for all your coolant system flush and fill needs.

Free A/C Inspection
Inspection includes: pressure check, and performance check. Any electrical diagnostic will incur separate charges.

Hoses
Hoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Sooner or later, your vehicle's hoses will dry out and crack. When you are ready for a replacement you can count on B & M Automotive & Diesel Service for all your vehicle's repair needs.

You not only have to get the hoses replaced with quality ones but you should have the work done by experts. To have the hoses replaced by auto cooling and heating experts - and get your car driving right - visit B & M Automotive & Diesel Service today. The mechanics at B & M Automotive & Diesel Service will thoroughly inspect your car's hoses; replace all worn hoses; and adjust the installed hoses.

Radiator Flush
A radiator is the part of your vehicle that keeps the engine cool and protects it from excessive heating. To be cool, the radiator needs to remain clean - always. With time, sludge, rust and other solid deposits build up inside your car's radiator. These make the cooling system become clogged and less effective. This in effect hurts your vehicle's performance. A regular radiator flush is enough to keep the system in shape. For this reason, make radiator flushing a part of your routine car maintenance schedule. For all your radiator flush needs, call 865-922-7111 or visit B & M Automotive & Diesel Service today.

Radiators
Radiators are heat exchangers for cooling your car's internal combustion engine. A radiator cools the engine by circulating an engine coolant through the engine block - it then loses the heat to the atmosphere through radiation. A radiator has a set of tubes through which the engine coolant flows. Fins surround these tubes. When the radiator fails, the excess heat produced by the engine could damage the engine components. To prevent this from happening, have your radiator serviced regularly. To have your radiator needs handled by experts, visit B & M Automotive & Diesel Service today.

It's important to prepare your car for the perils of summer - heat, dust, traffic jams - which increase the likelihood of a breakdown. At B & M Automotive & Diesel Service in Knoxville, our technicians can perform the necessary preventive maintenance to get your car ready for summer. These are some of the recommended services:

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.
