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 Precision Auto Repair at 717 Divisadero 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 Precision Auto Repair in San Francisco when it's time to recharge your AC freon.

Precision Auto 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 Precision Auto 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 Precision Auto Repair today and talk with our mechanics about getting the job done right. Visit us today at 717 Divisadero 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 Precision Auto 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 San Francisco 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 415-921-3317 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 717 Divisadero Street and we will show you the best AC recharging options for your car.

I had a check engine light and I brought it into the dealership. The dealership quoted me 2x the standard price for parts and labor so I called around to get another quote (probably 5 auto shops). Precision was the 5th place I called since no one else was able to get back to me quickly. Precision sent me a reasonable quote within minutes. When I arrived John Rodriguez was extremely friendly and said they could turn it around in less than a day. I barely ever leave reviews but I felt like I needed to for Precision Auto Repair. They honestly made my day so much better after getting no help from other shops that were closer to where we are staying. We are from out of state so we don't have a regular auto shop in SF. But if we did live here, I'd definitely bring my business to these guys. Really appreciate it!
