Your car or truck's AC system is under extreme pressure and the thermal expansion valve or orifice tube monitors the amount of pressure and the temperature of your A/C system. It calculates the precise amount of refrigerant that can safely go into the evaporator. A failing expansion valve or orifice tube often causes a vehicle's air conditioner to blow hot air.
Replace or Repair
- Expansion Valves: Too much refrigerant causes your evaporator to get too cold whereas too little refrigerant would result in inadequate cooling. The expansion valve is a complex valve that regulates refrigerant flow. This process of metering the refrigerant adjusts the flow according to the temperature of the refrigerant in the evaporator coil. Talk to one of the pro mechanics at 360 Auto Repair Services, as this part can be replaced on its own and does not require the entire replacement of the AC assembly.
- Orifice Tubes: Unlike the expansion valve, the orifice tube is a simple fixed device with no moving parts. It therefore cannot vary the flow of refrigerant into the evaporator, but rather causes a permanent restriction in the system. However, like the expansion valve the orifice tube regulates refrigerant flow through the system and filters debris which may come through in its screen. Often fixing a "bad orifice tube" requires replacing the entire evaporator assembly.

First and foremost, honesty and reliability is how I'd describe this shop and crew. Never been here but have passed it numerous times and 2 short stories.
1. Had to get my car smog, but wouldn't pass cause a few months before that my car battery died and had to jump start which reset the CPU, took a month and a half which I tried every other week to see if it would pass, they didn't charge me extra as long as I had the receipt. Even Sam remembered me which I was surprised as to how many people come there and it's my first time.
2. This is recent but I needed to get my oil changed and I needed an estimate for my broken AC. A few years ago I used to take it to Honda for oil changes and out of no where they showed me an estimate of how a tiny pebble was sucked into my vent and that's why my AC wouldn't work. I was skeptical because they're charging me 800+...luckily I don't drive my car too much as I have another so it wasn't a necessity and I even went to another shop by Costco, same bs story. I saved over 600+ with Sam and his team as there was no leaks or anything it just needed Freon.
I'll be moving soon but if I'm ever in town or knock on wood something happens I'll be sure to take it to 360 Auto Repair Services. Thanks Sam as well as your crew.
I've been going here for over ten years and I have brought a few cars to this company, their very professional, very detailed and willing to work with you. I highly recommend them.
