Recharge The AC Freon In Your Car Or Truck

MasterTech Automotive

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 MasterTech Automotive at 65 Elm Court 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 MasterTech Automotive in Colchester when it's time to recharge your AC freon.

MasterTech Automotive'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 MasterTech Automotive 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 MasterTech Automotive today and talk with our mechanics about getting the job done right. Visit us today at 65 Elm Court.

"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 MasterTech Automotive 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 Colchester 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 802-652-9991 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 65 Elm Court and we will show you the best AC recharging options for your car.

What Our Customers Are Saying

I showed up first thing in the morning and was greeted by Keith. He said good morning and asked how he could help. I explained my situation with my car and listened and stayed calm and said that even though they were busy he would work it in and check back at the end of the day. I get a notification midday that the car was done! He picked me up in my car!! No smoke and mirrors, straight talk from Keith! The best service I've experienced from a repair shop. He dropped me off and picked me up. He was knowledgeable and stayed calm. If I need the car serviced again, I'm not calling anyone else.

I wanted a second opinion on fixing the convertible top on my older BMW. I am so glad I did. Keith researched the issue and fixed it quickly and reasonably. I would recommend this garage to anyone.

I dropped my car off at Master Tech in Colchester to have my snow tires taken off and the regular tires put on. I left a note asking if he could help with the battery. Keith called me first thing the next morning and said he would drop my car off at my home and charge my car battery for me. Talk about service..........I have always been happy with the mechanical and customer services at MasterTech and I highly recommend Keith.
