Matthews Motors: Your Truck or Car's AC System

At Matthews Motors 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 11315 US Hwy 70 W-Business 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 919-550-2333 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.

Testimonials

AMAZING EXPERIENCE! I can honestly say I have never had a car buying experience like this before, impressed is an understatement. I had a few credit issues and was a bit apprehensive about applying for a loan. I decided to take a chance with Matthews Motors and completed the online finance application. I was immediately contacted by a sales rep and was able to schedule an appt first thing the next business day. I met with Uriel who was amazing and within 2 1/2 hours I left the dealership driving my new car. The amazing part is Uriel asked what I was looking for and what I was not looking for. Based on what I told him the very first car he brought me was the one. The 2021 Subaru Ascent Touring had everything I was looking for in a dependable 3rd row vehicle that didn't look like a minivan and was within my price range. You can tell they actually care as Ken assisted with the financial paperwork and did a great job explaining terms and answering questions. Uriel walked me to the service counter and introduced me to the staff for any future service needs. It was like becoming part of the family. I have had my new car for over a week, and they have followed up to make sure everything was going well. I am so happy I chose Matthews Motors as you could not ask for a wider selection of vehicles, better customer service and overall experience. They will be my go to for all future car buying needs which is great since I have to kids that are now pre-teens Thank you Matthews Motors for being so great. I will be referring all my friends and family for their future car buying.
