Recharge The AC Freon In Your Car Or Truck

Midwest Engine 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 Midwest Engine Service at 3712 Milwaukee St 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 Midwest Engine Service in Madison when it's time to recharge your AC freon.

Midwest Engine 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 Midwest Engine 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 Midwest Engine Service today and talk with our mechanics about getting the job done right. Visit us today at 3712 Milwaukee St.

"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 Midwest Engine 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 Madison 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 608-244-9040 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 3712 Milwaukee St and we will show you the best AC recharging options for your car.

What Our Customers Are Saying

I am from IL and was going to our home in Northern Wisconsin when I experienced car trouble. Lucky for me, I got off at the first Madison exit. I called Midwest Engine Service. They were AWESOME! They had me towed to their shop. Clean building and great staff. They got me back on the road within 3 hours. The repair bill was very reasonable. I would highly recommend this auto repair facility!

Dear Wayne, Thank you for your note regarding my Audi TT alignment mishap and for being so noble as to stand behind the work done at Midwest Engine. I'm sure it is difficult at times, when trying to run a business well, to negotiate mishaps, both with customers and your staff, and I appreciate that your rose to the occasion and did the right thing by me, even as a cost to you.
