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 Golf Crawford 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.
Awesome and honest service! My former mechanic retired, and he recommended Chris and his team. It's hard to find a great mechanic, but I'm grateful to be able to bring my car to Golf Crawford Auto Service.
I was looking for a car repair service and was referred to the Golf Crawford Auto Service. Chris and all of his mechanics were wonderful. I told him the problems I was having and he told me he would let me know what he found. Chris called and let me know what was wrong and also made some safety suggestions. I was told what the cost would be with or without the safety fixes. My car was fixed as promised and the cost were very reasonable. It's hard to find mechanics that are professional, reasonable and most importantly knowledgeable. If you ever need service for your auto, this is the one I suggest.
I've been meaning a review for these guys for a long time. We found Chris through a recommendation from Armin at Lake Side Auto Rebuilders (also an awesome shop I highly recommend) and Chris and his crew have exceeded expectations. We drive new and old cars, and most recently we were headed on a cross country road trip in our 10 year old suburban. We had not gotten more than 15 minutes out and a major piece broke off the bottom of our vehicle, and we had to get it repaired going any further on our trip. We took it to Chris, who is usually booked weeks out, and he was able to squeeze us in, miraculously had the part we needed, and got us up and going on our trip out west before the morning was over. This is just one of many times They have helped us. Chris will do everything he can to help you out - he & his crew know what they are doing and will give you an honest deal.
