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 Newtown Car Care Center, 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.

Went for an emissions test and didn't pass, Johnny immediately knew the reason for a fail. I replaced the battery and didn't drive enough miles to have it tested. He suggested I drive 50-60 miles and return. I did and it passed. Thank you Johnny!!!!

reviewiconInspections and Emissions, near Monroe, CT

We called Newtown Car Care Center on the off-chance that we could get contactless emissions testing because of the omicron surge, The employees here were so pleasant and helpful to work with and immediately accommodated our request. In fact, they even went further than we asked and told us that they had wiped down the inside of the car after performing the test. We were very pleased with their courtesy, and highly recommend this shop. Thanks to everyone with whom we dealt.

Tires

The most helpful group ever! Got a slow leak in my tire while driving on 84 and was lucky enough to be directed to Newtown Car Care. They checked me out and changed my tire in less than an hour (on a Friday afternoon!) I only wish I lived closer!

Failed my first emissions test. Tyler let me know exactly what I needed to address the issue - when I came back on a busy day, he got me in and out right away. Top notch customer service.

I needed a VIN verification on a big truck for 10 bucks. I was out of there in minutes! No back burner right on it! Thanks for the great service!

reviewiconI cannot recommend this gem of a business more highly!
Newtown, CT

Wow. I don't often think about the places/people who fix my car, but Newtown Car Care Center deserves special recognition. Just walking in the door was an experience; their waiting area is so cozy that I felt like I was in my living room, rather than an auto repair shop. And the folks who work there treated me more like visiting royalty than a customer. They could not have been nicer or more friendly. Johnny took care of me immediately and, thereafter, refused to take even a token gratuity from me for his trouble (turned out that I didn't need work after all). I only wish my car HAD needed repair ... that way, I could have claimed that I had contributed to their continuing success. I cannot recommend this gem of a business more highly! AAA+++
