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 Automotive Center of Slidell, 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 Customers Are Saying
I've been living in Slidell or surrounding areas for +-44 year and I can say with confidence as a former auto mechanic this place is top notch. You'd be shocked at what I've seen and experienced at several OTHER repair shops. These folks are extremely honest and not in anyway ripping people off. However if you are one of those little boys that need to blame other when you here the truth, then you don't deserve it anyway. This shop is simply the Very Best in town. The Dealerships don't compare. I wish I could give them 10 stars.

We had a great experience at the Automotive Center of Slidell. The business was very clean and welcoming and the staff was great. They explained everything very well and worked hard to try and save us money. We had a lot of work done; tires, shocks, alignment, etc. They did all the work in one day and I really appreciate that. AAA members get a discount. The next time I need my car serviced I will definitely be returning.
