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 X-Pert Automotive, 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.

Had my 2002 Thunderbird here for a complete A/C replacement. The time it took to complete the job was just one day longer than first scheduled. However, it was not their fault. The replacement parts were defective, because they did not preform to the standards they required. Even so, it was only one day longer than first planned. Joe was very professional and apologized several times for the delay. I highly recommend this X-Pert Automotive store.

I brought my Miata in for an AC charge. They were prompt and kept me up to date with the service. I decided to have X-Pert do my maintenance instead of going back to the dealer for this service as I have always done. -

Thank you so much to the staff at X-Pert Automotive. My battery died and I was able to jump start it but didn't have a lot of charge to make it to the dealer where I normally have my car serviced. I contacted X-Pert Automotive and they told me they would work me in during appointments. I was able to make it to the shop and waited just over an hour to get the battery replaced. Everyone I spoke with was courteous and professional and I plan to come back now that I've found them!

This was our first time to X-Pert Automotive. I was extremely satisfied with the service I received from everyone that works here. They are all very professional. They kept me posted on what repairs were needed, how long it would take and the cost. And I can now say Goodbye to all the rattling in the back of my car. Plus, their waiting room is clean and comfortable. We will definitely be going back for all our automotive needs. -
