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 Long Hill Auto Service at 1905 Long Hill 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 Long Hill Auto Service in Millington when it's time to recharge your AC freon.

Long Hill Auto 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 Long Hill Auto 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 Long Hill Auto Service today and talk with our mechanics about getting the job done right. Visit us today at 1905 Long Hill 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 Long Hill Auto 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 Millington 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 908-647-7984 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 1905 Long Hill Rd and we will show you the best AC recharging options for your car.


Reviews

My 2018 Hyundai Tucson’s check engine light came on solid. Vehicle didn’t feel right. I got my vehicle towed to Long Hill Auto. Coordinated everythung with Bob. He was great! My Tucson needed a big job done and it was described to me in plain English so I understood. I plan on driving this car much longer so it was key to get it properly diagnosed and fixed. I can’t say enough st how pleased I am.

Trusted Auto Service. This is unheard of these days. Bob and his crew are true professionals and have serviced my vehicles for a number of years. I would never go anywhere else. Bob has NEVER tried to "sell" me anything I don't need. All the work is carefully and timely performed. I am a big fan of supporting small business owners and I will continue to bring my vehicles here. Thank you Bob and Team!
