AC Diagnostic

The Basics Behind Air Conditioning System Diagnostic Services at Glenn Dale, Tire, Auto & Roadside Assist Auto Services

Your vehicle’s air conditioning system cools, purifies, and circulates air throughout the vehicle to promote a comfortable cabin environment and prevent driver fatigue.

The air conditioning system operates in a continuous cycle, sending refrigerant through a sealed system to remove hot air from the cabin compartment.

As the refrigerant flows through the air conditioning system, it is turned from a hot gas into a liquid, which is then cooled, turned into a gas again, and vaporized in order to absorb heat from the cabin.

At the end of the cycle, the cool air is blown into the cabin.

This process is made possible by the drive belt, which drives the compressor, the main component of the air conditioning system.

The compressor works in concert with the condenser, evaporator, and other parts.

If any of these components cease to operate efficiently, the functionality of the entire system is at risk.

When the performance of your vehicle’s air conditioning diminishes, allow us to identify and solve the issue through an AC diagnostic.

Customer Testimonials

We stand by our work.

- The owner John is very knowledgeable and the whole staff is friendly. I came for an oil change and to have my tires serviced (rotation, alignment and balance) because I thought they needed it. John told me I didn’t need service to my tires and they rode very well; no need to spend the money on a service that wasn’t needed. We all know many establishments would try to push a service for a dollar so his honesty is appreciated. Reasonable pricing and great service. Highly recommend! Services: Tire rotations, Oil change

- I had slow leak from a nail puncture and I was told by another tire shop that run flat tires could not be fully patched. He said it would cost $75 for a temporary fix but he recommended replacing, so I bought another tire online. [...] Thomas did such great work that it was not a temp fix at all and basically let me know the other place did not know what they were talking about. I have had no issues with the tire and its been over 3 months. He also said the repair came with a lifetime warranty so this place is all good in my book. Highly recommend. Service: Tires
