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 A & B Automotive Inc., 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.
Reviews
Highly recommend A&B Automotive! Back in March/April, I needed my front brakes replaced and the car shop I used to go had a price that was expensive. A friend recommended A&B and said he has been with A&B for decades. When I took my car to A&B, I found that the cost to replace my front brakes was $150 less than the other shop! I am now going to A&B for ALL my car needs! Ruth Chia, 06/14/2024 |
Great, honest mechanics! Elisa Hurwitz, 06/01/2024 |
Rachel was very helpful & friendly when I walked in for my appointment and Rachel found the notes from my conversation with the owner on her calendar (awesome). They checked my brakes & rotors first before doing any work to my vehicle, which is very refreshing compared to other shops. Thank you Rachel, the owner & your team; I will be back if and when needed and will refer your auto shop out to others for sure. I'm also glad I was able to get my car inspected at the same time.
