Thermal Expansion Valves For Vehicle A/C
Thermal expansion valves are important components of the air conditioning system that control how much refrigerant enters the evaporator. If it fails, it no longer regulates the air conditioner temperature, and the interior of your vehicle may heat up.
Replacing the thermal expansion valve promptly when it fails can save you expensive repairs on your car’s air conditioning system. If not replaced quickly, liquid may enter the compressor and cause internal damage, requiring replacement of major air conditioner components.

Thermal Expansion Valve Replacement
The thermal expansion valve is the component of your vehicle's air conditioner that regulates how much refrigerant is being used. On hotter days, more refrigerant is used and on cooler days, less is needed to maintain your cabin at an even temperature.
Failure of the thermal expansion valve in your vehicle is one reason that the air conditioner may stop working effectively. Air will blow warm or really cold depending on whether not enough or too much refrigerant is available to the system. Another indication of failure is that the AC compressor runs constantly, or frost comes from the vents.
Other components of the air conditioning system may need to be replaced at the same time as the thermal expansion valve. Get a quote on the thermal expansion valved replacement from a local Natrad technician who can perform a full cooling system check.
Natrad's nationwide warranty covers new air conditioning parts fitted to your car.
