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 Hill's Auto Repair at 22829 Colton Point 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 Hill's Auto Repair in Bushwood when it's time to recharge your AC freon.
Hill's 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.
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 Hill's Auto Repair today and talk with our mechanics about getting the job done right. Visit us today at 22829 Colton Point 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 Hill's 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 Bushwood 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 301-769-2400 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 22829 Colton Point Rd and we will show you the best AC recharging options for your car.
What People Say About Us

I've only used them for a few months, but so far it's been great. I wouldn't say they're cheap and I wouldn't say they're overpriced. Price seems pretty fair and high value. They certainly are trying to be good at customer service and good at quality of work. They can work on my commercial trucks. And I will continue to use them. It's hard to find a service that you trust and think tells you what needs money spent on it and where money doesn't need to be spent. I feel that way about these guys. -

I dropped my mustang off for an alignment after purchasing new tires elsewhere. My mustang had been involved in a deer collision before I bought it and the previous owner did all the repairs including some suspension parts. Wasn't fully faithful in the previous owners abilities. So dropped it off to a shop I had heard good things about for an alignment. What is super refreshing and the reason for 5 stars, is INTEGRITY. Very refreshing. They could have charged me for a full alignment, but instead only charged me for an alignment check as it was spot on the numbers. I would never had known, easy money. But INTEGRITY won. For this simple reason, they have earned my future business. The price was absolutely fair, and I trust they will do what they say they are gonna do.
