I recently serviced a dual-zone HVAC system to ensure optimal climate control in both areas of the home. This comprehensive maintenance visit began with calibrating the zone dampers to achieve proper airflow distribution. I then tested the functionality of the thermostats in each zone, verifying they were accurately reading and responding to temperature setpoints. To maintain indoor air quality, I replaced the air filters with high-efficiency pleated models. Additionally, I conducted a thorough inspection of the refrigerant levels, topping up the charge as needed, and verified all electrical connections were secure and in good condition. By addressing these key system components, I was able to optimize the performance of this dual-zone HVAC setup, ensuring the homeowner can enjoy consistent comfort throughout their living spaces.
