Absolutely. A common issue in our coastal climate is that heat pumps can struggle with efficiency, especially during colder snaps or when not properly maintained. We specialize in diagnosing and correcting these problems. This can involve checking and cleaning coils, verifying refrigerant charge, ensuring the defrost cycle is working correctly, and inspecting the thermostat settings. For homes with solar, we can also advise on system settings to maximize your solar investment and ensure your HVAC runs as efficiently as possible.
