Reliable Automotive: Your Truck or Car's AC System

At Reliable Automotive we understand how your AC system works. Your car or truck's AC system uses a Freon gas type refrigerant for cooling. For automotive applications, Freon is refined into tetrafluoroethane, a non-toxic, non-flammable and non-corrosive gas called R134a. The ability of the refrigerant gas to change its physical properties into a liquid as it is compressed and condensed keeps you cool on hot summer days.

If your AC system starts blowing warm air come by the store at 10708 Lilac Ave and talk with one of our auto parts specialists to determine what parts you need to get your AC working again.

Your AC compressor is the auto part responsible for compressing the refrigerant R134a. When it is compressed it becomes very hot. Because hot is the opposite of what drivers want in an AC system, the refrigerant must be cooled.

R134a is cooled by your car AC condenser. This auto part is a series of coils that look very similar to a radiator. Just like a radiator, outside air passes over the condenser to remove the heat from the compressed gas. It is then condensed into a very wet cold liquid. The receiver-drier absorbs excess moisture from the liquid. Next, your AC filter traps debris within the liquid that can cause clogging in your car's AC system. Call 314-733-5455 today and let our auto parts specialists help you find the right compressor, condenser or receiver drier to fit your car or truck.

At this point, the refrigerant liquid is still under too much pressure. The expansion valve and orifice tube take over and force the refrigerant to change from a high-pressure liquid refrigerant into a low-pressure liquid refrigerant mist before it enters the evaporator.

As the low-pressure liquid refrigerant mist flows through the evaporator, a blower motor pushes air across the cold tubes of the evaporator and cooled dry air flows into the passenger compartment of the automobile. The accumulator is a holding tank for the refrigerant as it exits the evaporator. While the refrigerant is circulating inside, the accumulator removes any moisture that may be present.

Call 314-733-5455 today and let our auto parts specialists help you find the right expansion value, orifice tube, and evaporator to fit your car or truck.


what our customers say

My 2000 BMW 323i broke down and would not start near St. Louis, MO during my drive from Cincinnati, OH to Los Angeles, CA. They towed my car to the auto shop and replaced the alternator. Although the shop closes at 5:30 pm and my car arrived after closing hours, they stayed until 8:00 pm to complete the job. I found the shop to be honest trustworthy and they changed a reasonable price for the work. I was able to continue my trip with only a two-hour delay. I consider myself lucky to have my car breakdown near this shop. I highly recommend this shop. They did an outstanding job.

Honest and professional repair shop! I can't say enough positive things about the crew and owner of this shop. If I could add an extra star I would.... This is the type of shop you look for to regularly service your vehicle. On a recent road trip from PA to Colorado we had a mechanical issue that required immediate assistance. We were able to limp the vehicle into the shops parking lot on a Friday night at closing time. The owner and his son didn't shoo us away but instead put the vehicle on a lift to determine if they could get us back on the road. After about an hour, they made the necessary repair and we were on our way. The price was fair... actually better than fair considering our circumstance. Great guys with integrity and an exceptional sense of humor. Make this your "go to" shop.... I would if I weren't 600 mile away. Thanks again guys!
