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 Everything Automotive of Jacksonville, 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.

What Our Customers Are Saying
On 3.2.2026 I used ChatGPT to find me an auto repair shop, with high ratings, 10 mi of my home. I reached out to the top three asking for quotes and after obtaining them Everything Automotive won out. Although their was in the middle of the three, they gave a waaaay better warranty. I spoke with Michael. He assisted me with obtaining more information and scheduling my appt. He was very patient and helpful. I had a great experience at Everything Automotive. The waiting area was clean, comfortable, and welcoming, which made the visit much easier. The staff were friendly, professional, and took the time to explain what was going on with my car. I initially thought my alternator needed to be replaced, but after diagnosing the issue they found the actual problem and it ended up costing much less, only $177. I really appreciated their honesty and not replacing parts that didn't need to be replaced. Tony, the owner, personally drove my car to make sure the stalling issue was fully resolved before returning it to me, and he even thanked me for my business. That level of care and integrity goes a long way. If you're looking for a trustworthy and professional auto repair shop, I definitely recommend Everything Automotive.
Great service, quick and they have thorough communication.
