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 Ann Arbor Transmissions at 4161 Carpenter 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 Ann Arbor Transmissions in Ypsilanti when it's time to recharge your AC freon.

Ann Arbor Transmissions'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 Ann Arbor Transmissions 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 Ann Arbor Transmissions today and talk with our mechanics about getting the job done right. Visit us today at 4161 Carpenter 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 Ann Arbor Transmissions 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 Ypsilanti 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 734-973-2340 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 4161 Carpenter Rd and we will show you the best AC recharging options for your car.

What our clients are saying about us

We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!

Honestly, the best shop in Ypsilanti/Ann Arbor. I have been to this Shop twice with two different cars and every time they have done nothing but great service. When I say, I think I found the one to go to that I would never stray away from, it's Ann Arbor Transmissions. Sidenote: It was months ago when I got service and I randomly decided to do this on my own because they are that great. quotes-image

Ann Arbor Transmission treats customers like family! My transmission went out, Ron fought for me when it came to my warranty company & provided elite customer service the entire process, keeping me informed & eased my worries. The technicians found other minor & not so minor issues with my vehicle & they made sure everything was repaired before my car left the shop, AT NO EXTRA COST! Justin was beyond professional when I spoke with him & incredibly knowledgeable when it came to warranty companies & even provided recommendations for companies that provide incredible service. As a woman it's hard to find reputable places that won't take advantage of me, this team at Ann Arbor transmission went above & beyond what words can describe. Echo (the most handsome shop dog) was the star of the shop & also provided greeting services as soon as I entered & promptly sniffed to ensure customer satisfaction. Thank you Ron & Justin & everyone at Ann Arbor Transmission for treating me like family & going above & beyond. Excellent, time-sensitive services. 1,000/10quotes-image
