When it is the hottest day of the summer in Chantilly, High-Tech Auto and Truck Center wants you to stay cool. Watch for early symptoms in your car or truck of an air conditioning system failure. Catching an issue early can save you time and money. If your AC system is charged with 1234YF freon and it creates an unusual amount of noise while running, produces an abnormal odor, or blows warm air instead of cool air, then you need High-Tech Auto and Truck Center to help you with a recharge.

In 2021, the EPA required all new vehicles manufactured in the United States to replace 134a freon with 1234YF freon because new 1234YF is better for the environment. The highly trained technicians at High-Tech Auto and Truck Center are on top of this new trend. They will evacuate and recharge auto AC systems with the 1234YF freon refrigerant recommended by your manufacturer. During air conditioning system diagnostics, we use advanced leak detection tools to ensure your car is not losing any of its freon.

If you feel like your AC is not working, you probably need a freon recharge

Don't suffer uncomfortably in Chantilly. If your AC isn't working well, bring your vehicle to High-Tech Auto and Truck Center.

The difference between current AC refrigerants such as 134a freon and 1234YF freon is significant. 134a freon is a greenhouse gas that is as harmful as carbon dioxide. 1234YF freon ensures that you and your passengers stay cool and comfortable all summer just like 134a freon, but it is not a greenhouse gas making it a better solution for the environment. From cooling issues to low airflow, you can rely on the pro mechanics at High-Tech Auto and Truck Center for fast and affordable AC repair and maintenance.

At High-Tech Auto and Truck Center we want to help you and your passengers stay cool. Call us today at 703-968-6648 and schedule an appointment to get your 1234YF AC system recharged.

What Our Customers Say

I had my 2018 Audi Q7 windshield replaced at Yellowstone Auto Glass and they provided excellent service from start to finish. Scheduling was quick and easy. They coordinated with my insurance company to get approval for the best OEM parts for my Audi Q7. The technician (Robert) came to my location to do the work. He was AWESOME! Robert took the time to thoroughly explained the work before starting. My car had generated may error codes from all of the electronic sensors. He explained to me all the possible outcomes in order for me to make an informed decision. He answered my numerous questions very patiently, professionally, and thoroughly. Robert performed the entire work in under 2 hours and that included windshield replacement and complete recalibration of the camera/safety sensor system. He clearly is an expert in this line of work. I couldn't be happier with my experience using Yellowstone. I highly recommend them.
