ACR Service | Best HVAC Repair in Huntsville, AL

Common signs in Huntsville include the system blowing cool air when set to heat, or warm air when set to cool, along with unusual hissing noises. This valve is crucial for switching between heating and cooling modes. We recommend calling ACR Service promptly for a diagnosis, as a faulty valve can strain the compressor and lead to more extensive, costly repairs.

Our technicians use electronic leak detectors and ultraviolet dye to pinpoint even small leaks in your AC system's coils or lines. Once located, we repair the leak, perform a vacuum test to ensure it's sealed, and then recharge the system with the precise amount of refrigerant specified by the manufacturer. This restores cooling efficiency and protects your compressor from damage.

This is a frequent issue in our Huntsville climate and often points to a refrigerant leak or a problem with the heat pump's reversing valve stuck in the wrong mode. Both issues prevent your system from absorbing heat from your home properly. ACR Service can perform a comprehensive diagnostic to identify the exact cause—whether it's low refrigerant, a valve issue, or another component—and provide a lasting repair.
