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 techniciansat Fausto's Power Garage, 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 clients are saying about us
We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!
Last summer an auto repair shop on Little Debbie Pky as well as another auto repair shop close to Cleveland said their computer analysis revealed a need of AC compressor on my 2015 vehicle at tunes of a few K's. I was referred to Fausto's by a fellow at Auto Zone to get Fausto's analysis. Computer analysis revealed that the compressor was working fine but unit was overcharged with freon. Freon was put at proper level and oil put on compressor and issues were fixed! AC was cooling properly again. You could have told me I needed a new compressor and I would have believed you! Thank you Brianna and Fausto's and team for your concern, care, honesty and excellent service. I will be returning for ALL my car's needs.
I have been coming to Fausto's Power Garage for years, and have always found the service to be excellent. Saturn told me that my old Saturn would always burn a lot of oil. Fausto showed me what part needed to be replaced and fixed it. When my air-conditioning went out at 4:00 on a Friday, Fausto stayed late to get it fixed before the weekend. I can't say enough about the quality of their service.
