Recharge The AC Freon In Your Car Or Truck

Pro Tune Plus

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 Pro Tune Plus at 828 Airport 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 Pro Tune Plus in Bismarck when it's time to recharge your AC freon.

Pro Tune Plus'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 Pro Tune Plus 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 Pro Tune Plus today and talk with our mechanics about getting the job done right. Visit us today at 828 Airport 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 Pro Tune Plus 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 Bismarck 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 701-224-1638 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 828 Airport Rd and we will show you the best AC recharging options for your car.

What Our Customers Are Saying

I needed a comprehensive pre-purchase inspection to buy a car sight unseen from the next state over. I am so grateful I found Pat and Joe. Not only did they do a great job trouble-shooting with honesty and integrity, they were really fun to work with! They went over and beyond to give me the best info possible to make a decision, then fixed the issues for a fair price. They were willing to keep the car for me an extra week, discussed all the details as we went along, and provided a peace of mind I couldn't have purchased the car without. HIGHLY recommend this outfit! Thanks, guys!

What a great experience we had with Pro Tune Plus! We were stranded nearby as we were driving through after a badlands camping trip when we noticed that 3 of 6 tire studs had sheared off, and only 1 of 3 remaining lug nuts were tight. We had AAA tow our truck to Pro Tune Plus on a Saturday afternoon, and I called Monday morning when they opened after the weekend and they said they would get it done that day, an easy inexpensive fix, and that was exactly how it turned out! We had since taken a cab to rent a car at the airport and drove home, and they took it the extra mile and parked our truck at the airport for us so we could drop off the rental car that night and not have to take a cab to pick up the truck at the shop, thank you!!

I called Pro Tune Plus just for some information regarding automotive wiring. The fellow I talked to was extremely helpful and pleasant, and spent a few minutes with me on the phone without seeming rushed even without any indication from me that I would be bringing my project in for them to work on. I am impressed that he genuinely was interested in sharing his knowledge with me and that he answered my questions to my satisfaction. Although I don't currently have need of the service Pro Tune Plus provides, the interaction I had with them ensures that the next time I do need it, they will be the call I make. Thank You for the gracious attitude, and information!

We were travelling across the country and had an engine light come on and still 2 states to go through. They took care of us and got us on the toad again. Thanks Pat and Joe.

These guys have been really great to work with and very honest. I haven't had a mechanic this good in years. So glad I found your place.

I highly recommend Pro Tune Plus based on my experience. I was driving from Virginia to Saskatchewan in January and my AWD system in my volvo xc 70 failed. I was stuck in a strange town and unsure of where to take my car. Both AAA and the staff at the Marriott Residence Inn seemed to think Pro Tune Plus would be decent. I was more than impressed with their service and the options offered in getting me back on the road. They did a great job; show impeccable attention to detail; and understood my need to get my car fixed and back to grad school quickly and cheaply. Fixing a Volvo in an area where there aren't alot of Volvos was scary for me but it worked out great!
