Steve's Car & Truck Services: Your Truck or Car's AC System
At Steve's Car & Truck Services 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 119 S Main St 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 920-648-2766 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.

Tires, near Lake Mills, WIBarbro Andren , 05/29/2025I was in Lake Mills this morning running an errand. I live in Cambridge (which by the way it’s not on your drop-down list. It’s only about 10 miles away so definitely worth the drive.) Anyway I was driving through town and my tire light went on. I pulled into a gas station and their tire gauge was broken, but the guy there said to me “See that building over there?” I said yes, and he said “Go over there. They’ll help you. He’s a really nice guy.” So I drove over to the back of the building, (Steve’s) and I ran into a really nice guy (Steve) working on a car at the back of the shop. I asked if he could help me, and he said sure, just go have a seat upfront, and indicated he’d take a look at it as soon as he could. They were crazy busy. I’ll be here for awhile, I thought. I went up front and explain my dilemma to Cassy in the front office. I was planning to leave at 7 o’clock tomorrow morning to drive to St. Louis, but when Steve, within minutes, showed me the size of the hole in my tire. I knew that was not going to happen. I have a Volkswagen Tiguan, four-wheel-drive, and tires are not easily found. But Cassie was on it and located some that could be delivered and put on the next morning. Meanwhile, Steve put my spare limper tire on, and all the while I was talking back-and-forth with a service guy at my car dealer in Madison. I learned my tires were under warranty and that my roadside assistance would take care of it (whew) but only if the work was done by them in Madison. I asked Cassy what I owed them, and was tempted to pay them double just to make myself feel better. It was beyond reasonable. I thanked Steve and Cassie profusely and actually felt bad that a warranty thing couldn’t be covered there. (But not sorry to save big bucks.) Meanwhile, another customer had been telling me how she’s been going there for 37 years, and that she couldn’t imagine going anywhere else. No kidding. If your car needs literally anything done to it, run don’t walk, to Steve’s. It’s one of those places that’s just like America used to be. Although all they did was change my tire, they absolutely made my day, and kind of restored my faith in humanity a little bit. Yay, Steve’s! Thank you!
