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 Long Hill Auto Service, 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.

In short, Long Hill Auto in Millington is the tops! Due to some forgetfulness about bringing an electric car adapter, Long Hill readily agreed to allow several hours of charging at their facility. Moreover, while dropping off the electric car, a gas version had tires severely low on air. Despite their full work load for the day, they took the time to check the car's computer generated TPMS and reset the "low pressure" code. The final piece de resistance was the addition of a small but useful bottle opener on the key chain with their name and phone number. And everyone could not have been more helpful or pleasant!! Give them your business; you will be glad you did! I am!
I am so grateful to Bob and Dylan at Long Hill Auto Service. As they were closing up for the Saturday, we pulled in because the undercarriage of our car popped earlier on the highway. They fixed it in a jiffy, gratis, and sent us on our merry way. If Bob had a shop in the city, he would be our go-to guy - super clean shop, polite guys, the kind of old school service you rarely see these days. ??????
