Rillito Automotive: Your Truck or Car's AC System
At Rillito 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 320 West Rillito Street 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 520-623-5260 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.

What People Say About Us
Love these guys! They are so efficient as well as honest and trustworthy. Highly recommend!
Rillito is my go to mechanics shop. They KNOW what they're doing, and they love their work. More importantly, I love their work, customer service, and Saturday hours. They have money saving tips, they check out used cars I've considered buying and saved me from some disasters! They also do on-site alignments and U-haul rentals. Did I mention they're also a bunch of really nice guys, too?
I have used Rillito for several years and found them outstanding. I feel they are an honest and give a straight deal as to what you need or don't need done on your car. I have enough confidence in them that my entire family use them. It is nice to know they are not trying to take advantage of their customers especially when you may not know a lot about the inner working of your vehicles now a days.
This shop rocks, they have 8 lifts, the waiting area is comfortable, and they do only top quality work. When I called in about both my rear and sliding doors locking up on my Chevy Astro, Tony was very understanding and offered an honest quote. When I came to pick it up (same day I might add) I couldn't help but notice they were working on a bright yellow Lotus. Jason my tech went above and beyond making sure the workmanship made the operation buttery smooth. I will definitely be returning!
We were on a road trip back from California to Texas and ran something over that busted our gas tank and exhaust pipe. Not being from here, we had no idea what to do. A kind worker found us a hotel and drove us there. Such hospitality, made a terrible event a little better.
Tony services all of our vehicles and does a great job!
