Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

Holm's Mechanical

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 Holm's Mechanical, 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

Hi. I just wanted to give my feedback on my experiences at Holm's. I need my vehicle to be in top form, I am a single gal, and need to rely on a shop that is honest, reliable, and gives me valued information about my vehicle. I came to Holm's because I needed to build a relationship with a shop that I can trust. I am very happy to have met Reg. Over two years, Holm's has never let me down. They caught a leaking water pump - when I had already gone to another shop about a mystery leak (who told me nothing was wrong). Holm's caught it when I wasn't even there for that purpose, and my engine was saved from frying. They have done my windshield, rear window regulator, full suspension, tires, brakes (completely restored to new from a botched job at another shop). My Jeep has never run better. It feels new again (2007), which makes me happy because I love my Jeep! They are the only ones I will trust, and am very, very happy with their service. Reg and his guys are friendly, give me all the information I need, and I never have to worry about un-necessary service other shops quote me on. As a matter of fact, I have no intention of ever going anywhere else for service. One-stop shop with honesty and integrity as a policy. I feel 100% confident to recommend them.
