Recharge The AC Freon In Your Car Or Truck
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 Dennis Hall's Auto Service at 221 Sherway Rd 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 Dennis Hall's Auto Service in Knoxville when it's time to recharge your AC freon.
Dennis Hall's Auto 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.
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 Dennis Hall's Auto Service today and talk with our mechanics about getting the job done right. Visit us today at 221 Sherway Rd.
"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 Dennis Hall's Auto 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 865-690-1151 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 221 Sherway Rd and we will show you the best AC recharging options for your car.

What Our Customers Are Saying
Hands down the nicest people ever.They replace my headlight for free today.For my birthday what a blessing I will use them for everything I need in the future they didn't have to be so kind. Such an amazing place I recommend them to everyone having car trouble go see these guys
I took my 93 Nissan to Dennis Hall back in March because it was idling rough and had them go ahead and do a rear end service on it as well. They did great work and at an adorable price. It is now August and I noticed it looked like my rear end had leaked a little bit and called them to see if I need to schedule an appointment to get it looked at again. They told me to just stop by and they would check it out free of charge to make sure everything still seemed correct. They got me in and out quickly and very pleased they took the time to make sure their work was correct and didn't make me have to pay for another service. I will be going back for all my vehicle needs 10/10 auto shop!
Had an issue pop up when we were traveling on the interstate. We stopped here and they helped us out super quick and were very nice. If I lived in town this would be my mechanic.
