AC Air Conditioning Auto Parts


Pete B Service Inc: Your Truck or Car's AC System

At Pete B Service Inc 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 376 Middle Country Road 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 631-924-9292 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 631-924-9292 today and let our auto parts specialists help you find the right expansion value, orifice tube, and evaporator to fit your car or truck.

I was looking around for a classic Volkswagen specialist to restore my original 1968 Meyers Dune Buggy for quite a few months. I checked out places as far away as upstate New York, Connecticut and Rhode Island . I finally came across Pete B service after someone I met told me there was a great group of classic VW specialists at Pete B in Middle island . After going down to there shop and meeting Dirk and his crew I knew they were the right guys to work on my classic VW They did a fantastic job restoring my dune buggy. When I purchased my car it was sitting in a warehouse for over 35 years and needed everything. Dirk, Rich and Tom replaced parts when needed and rebuild the steering, brake system, fuel system , complete wiring harness and installed an engine I purchased for the car. It now runs and looking amazing!! Their attention to detail is top notch. The work was completed on schedule and to the original quoted price. As a bonus , Dirk the shop owner raced sand rails and is involved in off road racing. So he knows how to assemble your ride for on and off road use I highly recommend Pete B Service . If you have a classic VW I would not go anywhere else. 5 stars quotes-image
