Recharge The AC Freon In Your Car Or Truck

B & M Automotive & Diesel Service


Your truck or car's AC system is almost completely airtight, but your freon refrigerant is always slowly leaking out. Eventually, a car will lose enough freon so that its air conditioning system will no longer cool effectively. At B & M Automotive & Diesel Service at 7301 Maynardville Pike we are ready to recharge your AC to help you keep your car or truck's cabin temperature cool.

"Help My AC Only Blows Warm Air!"

New advancements in R134a freon systems means that freon in newer cars doesn't leak out as much as old R12 freon systems. The average new model economy car only leaks about 0.41 ounces of refrigerant per year. Come to B & M Automotive & Diesel Service in Knoxville when it's time to recharge your AC freon.

B & M Automotive & Diesel Service's Fast 3 Step Process:
  • Vacuum out all the old refrigerant before refilling it.
  • Add new R134a refrigerant.
  • Pressurize your car's AC system and test for mico-leaks.
"Does B & M Automotive & Diesel Service Have R12 Freon For My Classic Car?"

Unfortunately R12 freon is no longer available. If your car or truck was made before 1994 you must convert your entire AC system to the new R134a standard. This involves replacing dozens of seals and several AC auto parts. R134a is a more highly pressurized and much more efficient refrigerant pound for pound than R12. Most classic car AC compressors and condensers cannot withstand the intense pressure required and choose to add about 25% less freon to accommodate older systems. This means your AC may not cool as well as it used to. Converting your R12 system to R134a is a big job so stop by B & M Automotive & Diesel Service today and talk with our mechanics about getting the job done right. Visit us today at 7301 Maynardville Pike.

"Is Used Freon Ok?"

Many auto repair shops resell used AC refrigerant. The old freon is cleaned using a specialized recovery machine that removes contaminants. Used freon provided by B & M Automotive & Diesel Service works just as well as new freon after it's cleaned. Accepting used freon is a great way to help minimize the impact freon has on the environment.

Freon gas becomes a liquid when pressurized inside your car's A/C system but returns to its gaseous state as it leaks out. Many drivers in Knoxville are completely unaware that they are losing freon until the day when they turn on the car's AC and find only warm air blows out. Call 865-922-7111 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 7301 Maynardville Pike and we will show you the best AC recharging options for your car.

Reviews

I was desperate to find a locally-owned quality repair shop I could TRUST to take care of my cars. After many disappointing experiences elsewhere, I went to B & M and WOW! Bob, the owner for 30 years, is thoughtful, considerate, thorough & a true master of his profession. Marty is quick to recognize a problem & communicate issues clearly in simple terms that are easy to understand. He also has a fun & witty sense of humor which certainly helps when you're stressed about car problems! They finish repairs ON TIME & CORRECTLY, and always return calls quickly. Bob insists on using only PROVEN QUALITY PARTS, & rates are always reasonable. What else could you possibly want from a repair shop?! I'm SO grateful to find this one!!!

My parents are in from NY and were having car trouble so I recommended B & M because they have fixed my car in the past. I find them to be honest and have reasonable prices. I say honest because I had a brake problem that another mechanic quoted me at $600 but at the time I couldn't afford so I brought my car to B & M for just an oil change. When I drove off I noticed the brakes felt like they were working properly again so I looked at the invoice from B & M and noticed they replaced a simple brake hose at no charge! The staff is very kind and welcoming and the owner Bob was there to greet us. They fixed my parents car and had them back on the road in no time. This place is a hidden gem. We will definitely be loyal customers for life now :)
