Hud's Auto Service: Your Truck or Car's AC System

At Hud's Auto Service 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 8212 Valencia 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 806-866-9898 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 806-866-9898 today and let our auto parts specialists help you find the right expansion value, orifice tube, and evaporator to fit your car or truck.

Took my vehicle as a walk in and had it done very quickly. My vehicle is now running better than ever at half the price the other places would charge me!

We have been back in Lubbock just over 2 years. When we asked for a good reputable shop, Huds came highly recommended! Since we have been back, we have had my Jeep in a few times now. (I know Just Empty Every Pocket) From the first hello when you call to schedule-to the time of pick up- their customer service has been top notch and will keep us coming back! Thank you to every team member at Huds for your warm welcomes, friendly smiles, honesty, and helping me NOT empty every pocket!

Honest and fair. That's all you can ask for in an auto shop these days. And it's hard to find someone you can trust. Well, Hud's has proven themselves as a trustworthy business to me. They don't try to upsale or mislead you, and their prices are always fair. As an electrician, I know labor costs money. They do a good job labor wise and typically pretty quick too. They also stand by their warranty for any type of work done. They have taken care of my daughters car multiple times (it's an old car) and have always done a good job. I would definitely recommend Hud's for any type of auto work.
