Warning Signs that You Should Have Auto Air Conditioning Repair & Service

Your Car’s AC System Explained

To understand any service, you want to first grasp how it works. The air conditioning system in your car is broken into two main parts. There is a high side and a low side. On the high side of things, you have a compressor. This operates just like a pump would. It moves the car’s refrigerant throughout the system and pushes it into the condenser. This is the location where all the higher pressure gas gets cooled.

On the low side, you have an evaporator and expansion valve. The valve’s job is to restrict and meter all of the refrigerant before it makes its way to the evaporator.

There are more parts involved than just that. You also have gaskets, hoses, O-rings and a belt working in conjunction with the system. Every component, no matter how big or small, needs to do its job for you to remain comfortable in the cabin.

Recharging Your AC Refrigerant

If you find that the cabin isn’t getting cool like it once did, you might need a refrigerant recharge. At Minnie’s Auto Repair, we handle all your needs whether you are running a system with R12 or R134a. Neither of these disintegrates on its own, so if you are low, there’s likely a leak in the sealed and pressurized unit. We will inspect all the hoses, components and connection fittings to determine the cause of the problem.

Another reason you want to have this promptly addressed is because the automotive refrigerant damages the environment. As it leaks out, it causes holes in our ozone layer. Once we figure out where the leak is, it won’t be hard to repair it and get you back on the road. Then, you can find the relief you need once again from the heat or cuddle up in the driver’s seat to escape the cold.

If you drive a car that’s older than 1994, it’s possible that you are still using R12 refrigerant. This has been upgraded to R134a, but it’s not difficult for us to perform a refrigerant replacement service to get you up to date.

AC System Repairs

Other than the refrigerant, you have to consider all the other parts we mentioned earlier. Because there are moving and working components to your system, there are other things that could go wrong.
