Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Jim's Towing & Automotive
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 Jim's Towing & 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.

Just experienced wonderful customer service...professional, safe, accommodating and timely!
Keep your hair dresser close and your mechanic closer! I had the best experience ever! This shop is white glove clean, the customer service beat what you get at the big dealerships and they are HONEST!!!! Bob saved me a boat load of money and gave it to me strait. Hopkins Ford tried to pad their pockets thinking I was a weak female who falls for the line "Ma'am, you need to replace the whole front end, and by the way, we can do it today and give you a ride to work. It will only cost you $680". Yeah right! How can a truck that cost $32,000 and is just 5 years old require that much work????? It doesn't! Bob, THANK YOU! You have a new customer, WHEN I need work and I'm going to send everyone I know to your shop. It's really nice to know there are still a few honest men out there who aren't trying to make a million bucks on the backs of hard working people. BLESS YOU!
