Signs You Need Heat Pump Repair

Schedule professional heat pump repair if you notice:

• System blowing cold air in heat mode (or warm air in cool mode)
• Ice on the outdoor unit or frozen coils
• Short cycling—turns on and off repeatedly
• Unusual grinding, buzzing, or clicking sounds
• Rising electric bills with weaker comfort
• Thermostat calling for heat/cool but no response
• Emergency heat (aux heat) running constantly

Ignoring these symptoms often leads to compressor failure—a repair that costs far more than an early diagnostic visit.
