Troubleshooting Your Car's AC: Common Issues and Solutions

AC Is Not Working Diagnosis

If your car's AC is not working, diagnosing the issue can involve multiple steps. It may be useful to have some basic knowledge about the system before attempting to diagnose it. Here are some general steps to follow:

Check for leaks: To ensure your AC is in good condition, inspect its components such as the compressor, hoses, and condenser for any visible damage. Additionally, examine the fittings and connections for any leaks.

Check the pressure: To determine if there is an issue with the AC system, please check the high and low side pressure using an AC gauge. If the pressure is too high or too low, it may indicate a problem with the system.

Check the compressor: Please ensure that the compressor is working properly by listening to any unusual noises when the AC system is turned on. Also, verify that the clutch is engaging correctly since the compressor is the core of the AC system.

Check the refrigerant levels: To determine if there is a leak or problem with the system, check the refrigerant level using a refrigerant gauge. If the level is insufficient, it may indicate an issue.

Check the electrical system: Please inspect the AC electrical system by examining the fuses, relays, and wiring to ensure that they are all functioning properly.

Check the cabin air filter: It is recommended to inspect the cabin air filter because if it is dirty, it may impede airflow and decrease the effectiveness of the AC system.

It is recommended to take your car to a qualified mechanic or AC specialist for diagnosis and repair if you are not comfortable performing these steps yourself.

Arrived at my house on time, did a great job. Saved me the trouble of limping my car to a shop, and did it for far less than other quotes. I would recommend them to anyone needing a repair - .

Used this company to replace the rear brake shoes of my 2014 Nissan, Sentra. They answered all my questions and were very responsive. They were very honest, efficient and showed me the work needed for the vehicle. They did not attempt to sell unnecessary work. They have very reasonable rates and will definitely use them again. I highly recommend!

My passenger side rearview mirror was broken and needed replacing. I submitted a request o several businesses on Yelp and Instant Car Fix got back to me the quickest. The fact that they come to your location makes things incredibly easy. All we had to do was wait for the part to ship and the repairs took less than 30 minutes. Great company!

I was super skeptical about this at first as it seemed a bit too good to be true - as in, I don’t have to deal with the headache of dropping my car to the garage, wait for hours and not know when the car will be ready? Turns out, using Instant Car Fix really was pain free. Pricing was clear upfront, the mechanic came on time and all occurred while I was at home. Highly recommended and will definitely use again

I scheduled brake service after my dealer said I would need to do it. I assumed that the rear brakes are what required service. When the technician came he checked the brakes and told me the rear brakes were as good as new. They serviced the front brakes on another appointment. I was very impressed by the honesty and efficiency, with no attempt to up-sell unnecesary work. All at very reasonable rates, especially compared to the dealership. Will definitely use them again.

Replaced brake pads and rotors on my 2013 Chevy Equinox. I am traveling to attend a wedding in Virginia and drove from Chicago. Having car problem in Northern Virginia where I don’t know anyone. RJ was very friendly and helped me fix my car promptly with very reasonable price. Mechanic came to my hotel and changed the brake pads and rotors on my rear wheels. This was very convenient and so easy. Thanks for the help.

This is by far and away the best experience I’ve had with any mechanic. They arrived early, got the job done fast and even explained what they were doing so I could get a better understanding of my vehicle. Not to mention the fact that they were lower in cost than the quotes I received from other companies. The service and convenience just can’t be beat.

This was fantastic! I googled for somewhere to get new brakes and rotors and when I first heard about the mobile autoshop, I was hesitant. But the guy came and fixed it and honestly, I'm really not going to go back waiting hours in an autoshop. 5 stars.
