Combo Tune Up Performed- performed maintenance on 2020 Lennox system. Upon arrival system is working and operational. I began my maintenance at the outdoor unit by breaking it down and cleaning with water and solution. Removed heavy amounts of dirt and debris. I then inspected all electrical components for signs of wear and checked for tight connections. I measured amp draws and recorded refrigerant pressures. I then proceeded to the indoor furnace unit.

Inspected the blower housing for balance and dust. Checked heating components for wear. Inspected heating components for proper operation. Filter has been changed at this time, home owner supplied.

Performed furnace maintenance on 1993 Day N Night furnace. System is original to home, has not been maintained in the past 10 years that he’s lived in the home. Cycled system for heating. Verified proper heating sequence of operations. Temperature rise across heat exchanger is extremely high, and furnace is extremely hot to the touch. Ductwork Is in very poor condition and is very undersized and restrictive, which is causing the high temperature rise. Inside of system is extremely dirty, as well as blower wheel inside the blower compartment. Amperages are normal. Unit has a lot of flame roll out. Heat exchanger can not be properly inspected due to a hard gas line that is running across the middle of the front of burner compartment, and blower wheel can not be pulled out due to attic configuration. System is extremely old and In very poor shape. Also condensation lines are clogged, and water has started falling through and damaged the ceiling. Went over findings and recommendations wi

Arrived on site to perform diagnostic on 5 year old Rheem furnace. Homeowner states that the system is not heating correctly. It will run for about 1 or 2 minutes and then it’ll shut off. She then has to pull the thermostat off and then it’ll work for another little while. Cycled system for heat. System came on and started heating, but shut off after a short amount of time. System threw error code for high limit shutoff. Filter that was in the register was extremely dirty. Homeowner was also unaware that there was another filter inside the unit that had never been changed. Both of these filters were causing the unit to be restricted, and cut off on high limit. Removed both filters from system. Cycled system for heat. Furnace kicked on and ran normally until it reached desired setpoint. Advised replacing filters more frequently, and also removed filter from inside the unit as only one is needed. Unit does not have any condensation safety switch or surge Protection. Went over finding
