Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
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 Highlands Auto Center, 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.

We took our 2007 Jeep Liberty in due to some engine problems. Well, they looked in over and told what I had already suspected - the engine was in bad shape and loosing oil.The owner of the garage made some phone calls and presented us with a price much lower than we expected. We had them do the job (in one and a half weeks) and one their quoted price, we've driven the Jeep for a few days now without any problems. They did a great job and I would recommend them to everyone. Thanks guys for your detail to your work and low prices. I've ad them work on all 4 cars now, we are very satisfied with the out come of each car. I even bought a used car from them -works great. Thanks again Larry F
Great service. Friendly. Reasonable pricing. Good location for us near NW Hwy and Plano Rd.
I am beyond grateful for the amazing service I received here! They fixed my O-ring, gasket cover, and gave my car a tune-up. The work was done thoroughly, professionally, and at a fair price. But what truly touched me was when I noticed later that they went above and beyond, they fixed my bumper without even charging me. That kind of kindness and integrity is so rare to find! Thank you for not only fixing my car but also showing such care. I highly recommend this shop to anyone who wants excellent service and honest people who treat you like family.
