Heat Pump Tune-Up: As part of routine seasonal maintenance for a residential client's heat pump system, I performed a detailed tune-up. This involved inspecting and cleaning the outdoor and indoor coils, checking refrigerant levels, lubricating moving parts, and verifying the functionality of the thermostat. I also assessed the defrost cycle to ensure it operates efficiently during colder months. This meticulous tune-up not only enhances the heat pump's efficiency but also prepares it for optimal performance in different weather conditions, providing the homeowner with consistent and reliable heating and cooling.
