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 7Stars Transmissions, 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.

2nd time going to 7Stars transmission and both times did a great job! Was hesitant because I just found them on Google and 5 min from my job where my truck was broken down. Decided to give them a try and I dont regret it! They know what they are doing and are reasonable with pricing. Im already letting everyone I know about them.

(Translated by Google) My experience, every time I go for an oil change, is too good, from the mechanics to the people who are in customer service. I recommend this place. I have a BMW that I always leave in the best hands of 7Star Transmission.

This group recently put a new engine in my dad?s car, and it runs great. They also have done my oil change in my truck. Very reasonably priced, great customer service, and family owned business. I will always recommend them to anyone. They have also done my oil change twice on my 2010 F-150. Best shop around, reasonable prices too.
