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 G & L Automotive II, 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.

For the next year, I found this company as a friend of mine told me how they replaced the engine in his truck and he has had no trouble with that engine for over five years. I did start taking my 20 year old Subaru to them and they were able to fix any and all problems I just recently today I got my Mitsubishi back which had a problem in the crankshaft, and I am very happy with the work that was done. I will say this is a group of well trained and honest mechanics when I had my Mitsubishi towed there the tow company told me that if I would let their mechanics work on it, they would take 10% off and I told them I don't know you or your mechanics. I do know George and the mechanics at G&L and I have found them to always be honest and professional doing a good job that last thank you G&L.
I came in thinking I needed some major work on my front end suspension. I was sure I'd be hearing words like tie rods and ball joints. It turned out to be a a loose front tire. The lug nuts were not snuggly tightened after a flat repair. The cost was zero!! I was ready and willing to pay for front end work. These guys are amazing. They are very good, HONEST, mechanics. I HIGHLY recommend them!!
