I completed a thorough A/C checkout on three heat pump systems, providing full summer maintenance. The service included checking refrigerant levels, inspecting the condenser coils, and testing the blower motors to ensure proper function. After confirming that all systems were operating normally, I also reviewed key maintenance tasks with the homeowners. This included educating them on the location of their air filters and explaining the recommended intervals for filter changes. Additionally, I provided an overview of basic equipment operation to help ensure efficient performance between service visits. All three systems are currently showing normal operation and are ready for the summer season.

Replaced the furnace control board on a Trane XR80 unit due to a malfunctioning blower relay that intermittently stuck closed, causing the blower motor to not cycle properly. Installed a new OEM control board, ensuring compatibility and reliability. After installation, tested the system in both heating and cooling modes to confirm normal operation. Regular maintenance and timely repairs are essential for system efficiency. For professional HVAC repair services, contact us to ensure your system runs smoothly.
