This is often caused by a faulty reversing valve, a common issue in our area due to the frequent cycling our coastal climate demands. The valve directs refrigerant flow to change modes. When it gets stuck, fails, or loses its charge, your system can't switch properly. Our technicians at Premier Heating & Air Conditioning perform thorough diagnostics to pinpoint the exact cause—whether it's an electrical issue, mechanical failure, or refrigerant problem—and provide a precise, lasting repair to restore your comfort.

Thermostat calibration issues are very common and can stem from aging components, dust buildup, incorrect leveling on the wall, or even proximity to heat sources like sunlight or appliances. An uncalibrated thermostat causes your HVAC system to short-cycle or run inefficiently. We provide expert thermostat calibration, testing, and, if needed, replacement with modern, accurate models. This ensures your system responds correctly to your settings, improving comfort and preventing unnecessary strain on your equipment.

We offer comprehensive preventative maintenance specifically designed for our local climate. Our service includes cleaning and inspecting heat pump components (like the reversing valve), testing and calibrating thermostats, checking refrigerant levels, and ensuring all electrical connections are secure. This proactive care helps catch small problems before they lead to a breakdown, improves system efficiency, and extends the life of your equipment, saving you money and hassle in the long run.
