Today I completed a full fall maintenance on one HVAC system. I inspected heat, exchanger, burners, and ignition components for safe operation. I checked blower assemblies, airflow, settings, electrical connections, breaker, sizing, and motor amp draws to verify proper performance. I tested controls and safety switches and inspected for any potential safety or cold concerns. All systems checked out in our operating as designed at this time. I also installed a Apco-x and a Iwave for customer. I educated customer on how it works and I tested functions to make sure it works. There are no issues on this unit. Customer is happy.
