Arrived at the customer’s home to complete quoted repairs on the whole home HVAC system. Customer noticed that the thermostat for the system was off. Discovered that the condensate pump was unplugged, preventing the furnace condensation from leaving and tripping the float switch. Plugged the pump back in and the furnace began to work properly. Connected the two flex ducts with duct strap, rerouting them around the new support joist. Discovered that there was a horizontal section to the new joist, so the metal supply duct needed to be rerouted. Picked up R-8 8” flex duct from Apex Supply Marietta. Replaced the supply with a flex duct and secured it with duct strap. Disposed of the old metal duct. Reported results to the customer.
