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 Alexander's Diagnostic, 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.

Testimonials

We have been coming to Alexander's since we moved here 4 years ago. My husband and I are absolutely pleased with the mechanics and customer service. Last February 2018 we were looking to buy a decent used car to pay cash out right. Eric and the mechanics looked at each car we brought up for a once over before we dropped about 7000.00 on one that finally got the green light and passed they're inspection. In the last 2 months my car did need some work They did the brakes all around and struts on the front. The pricing was fair and they even helped us out and let us pay the last few hundred dollars 2 weeks after repairs were done just this week we put tires on it so they did the alignment and I also needed stabilizer bars repaired on the front end Again pricing was fair and they taxied me too and from the shop as my husband was off to work until whenever the job lets him go. We are big on supporting local businesses as both of our parents had they're own shops before they retired. I appreciated the customer service We will be returning and definitely recommend them Thanks again
