Common Auto AC Problems
While different brands of cars have unique problems, there are some issues that happen with all AC systems. Auto AC problems include: low refrigerant pressure, failing compressor, or electrical problem.
Failing AC Compressor
A failing compressor is a serious problem to watch out for. If a compressor fails it can fail catastrophically and shed pieces through the hoses, condenser, evaporator, and accumulator. This buildup of debris in the system if not caught will kill a new compressor. Common signs that you’ve got a failing AC compressor is a squalling sound when you turn it on or ticking noises.

Low Refrigerant Pressure
Over time Auto AC systems stop blowing as cold even on the coldest setting. This is frequently caused by low refrigerant pressure. Loose or leaking hoses in your AC system can lead to low refrigerant pressure. If this happens your AC will gradually get less effective and leave you with a car that’s not ready for summer driving in Arizona.
Damaged Hoses & Lines
Whether the hoses or lines are simply old or have been damaged they will lead to problems. The number one problem is a loss of your AC refrigerant. We can carefully examine your AC system to find the leaks, fix them, and replace the refrigerant you’ve lost. This will restore your vehicle’s ability to blow cold air when you need it.
Auto AC Electrical Problems
Another part of modern vehicle AC system problems is electrical issues. The wires running between elements, the fuses, and the control system are all susceptible to wearing out or being damaged. If you’ve got a bad relay, fuse, or short in your electrical system the AC system may not work well, or not work at all.
