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 Automotive 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.

Trustworthy, Courteous, Professional... Issue: Clunking noise, under front passenger side when driving Affordable Automotive completely surpassed my expctaitons when I took my car to them, after another repair shop quoted that I needed a new CV Axle and that the total cost would be $1700 to replace. I took it to AA on a whim and recieved a prompt, polite call that stated the issue was only a loose caliper. They stated they tightened and that the cost was zero bc all they had to do was to tighten the bolts. I did ask them to do another service while it was there and paid for that of coiurse. They did a 40+ inspection on my car and proivded me a rpeort of what else may need service eont he future. I am now 6+ weeks from that service and the car is still quite and driving well. Unlike MOST service stations, AA is trusting and the cost of labor is budget friendly and the staff are extremely knowledgable and polite. If you have any issues with your automobile, don't hesitate to take it to Affordabel Automotive, they will have you back on the road quickly while easy on your pockets! I appreciate your honesty and you now have a customer for life!
Suspension System Parts, near Fredericksburg, Virginia I bought my tires from them a year ago and suddenly I had a flat from a screw. I was distraught and called to see if they could help, and they were amazing! They couldn't patch it but they got my donut on and ordered a new tire. The next day I came straight from work and my car is highway ready again! And no cost to be because my tires were covered by road Hazard protection!
