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 Rev Auto & Truck Repair at 2105 S Kalamath Street 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 Rev Auto & Truck Repair in Denver when it's time to recharge your AC freon.

Rev Auto & Truck Repair'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 Rev Auto & Truck Repair 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 Rev Auto & Truck Repair today and talk with our mechanics about getting the job done right. Visit us today at 2105 S Kalamath Street.

"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 Rev Auto & Truck Repair 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 Denver 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 303-386-4172 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 2105 S Kalamath Street and we will show you the best AC recharging options for your car.

I’ve been to this shop a few times now, and every experience has been great. It’s hard to find an auto shop that feels this trustworthy. They never try to upsell or push unnecessary repairs, which I really appreciate. One situation that really stood out to me was with my newly obtained preowned car. Liz gave me helpful advice about lemon law options and encouraged me to push back on the dealership first instead of immediately spending thousands at the shop. They clearly care more about helping their customers than making a quick profit. I feel confident bringing my car here and would definitely recommend them to anyone looking for reliable and honest service.quotes-image
