Today we came out and performed hvac inspection on two systems, flushed drain lines and treated. Replaced filters, cleaned fuel rails, cleaned flame sensors and inducer ports. Inspected all electrical components and connections took amp draws on all motors. Checked gas pressures, inspected all ductwork and checked all thermostats. Checked all operations and left equipment operational. Main level system has ductboard plenums and both systems have no IAQ will attach estimates for all.
