Qualified HVAC Repair in McAllen, TX 78501 - Rio Comfort AC & Heating

That's a classic sign of an evaporator coil freeze-up, a common issue in McAllen often caused by dirty air filters, low refrigerant, or airflow problems. Running it in this state can damage the compressor. Rio Comfort's technicians will first safely thaw the system, then perform a thorough diagnosis to find and fix the root cause—whether it's a refrigerant leak, a clogged filter, or a failing component—to prevent it from happening again and restore efficient cooling.

Screeching or grinding noises often indicate a failing blower motor bearing, a frequent repair need in our area's hard-working HVAC systems. Continuing to run it can lead to a complete motor seizure. We recommend turning the system off to prevent further damage and calling Rio Comfort. Our experts will inspect the blower assembly, determine if the motor needs lubrication, repair, or replacement, and get your system running quietly and effectively again.

The intense South Texas heat means your AC system works exceptionally hard.
