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 Michael Bogart & Son 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.

Good people, great shop, you can't go wrong getting your vehicle worked on here!

Can't go wrong at Bogart's. My little baby Jeep feels brand new, and I'm safe on the road. Very friendly staff and excellent prices for repairs. Love Bogart's!
Excellent service. Friendly and accommodating. Fixed and inspected dump truck when others wouldn't take it. Will be using Bogart's as our auto repair shop of choice!
Used as a drop-off for our U-haul. They were amazing. We over filled on gas so they didn't charge us for a few miles we went over. Very thankful and pleased. We were able to drop off while the garage was closed. Thank you Bogarts!
