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 Affordable Auto Repair, 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.
OUR REVIEWS
Engine Maintenance, near Miami, FLEzequiel Hernandez, 12/04/2023I was experiencing a constant knocking noise in my car and decided to take it to the dealer for a diagnosis. To my shock, they quoted me an outrageous amount to repair the issue, which left me feeling frustrated and skeptical. I decided to seek a second opinion and thankfully stumbled upon Affordable Auto Repair Miami. The owner Neil was friendly, attentive, knowledgeable and most importantly, honest. After carefully examining my car, he quickly identified the source of the knocking noise. To my relief, he informed me that it was a bent push rod causing the problem, and the repair could be done at a fraction of the cost quoted by the dealer. I couldn't believe my luck! Not only did I save a significant amount of money by coming here, but they also went above and beyond by providing me with a useful recommendation to prevent future issues. Neil took the time to explain everything in detail, ensuring I understood what was done and why it was necessary. The repair was completed in a timely manner, and when I picked up my car, the knocking noise was completely gone, and I couldn't be happier with the results. The transparency and integrity displayed by this mechanic are truly commendable. I highly recommend this shop to anyone in need of reliable and trustworthy automotive services. Neil and his team have earned my trust and loyalty, and I will undoubtedly be returning to them for any future car troubles. I have already referred the shop to several of my friends. Thank you for saving me from unnecessary expenses and providing exceptional service!
