Maintenance Performed inspection and maintenance visit on 2018 Lennox furnace and AC system. This is a builder grade system. It is zoned. Upon inspection found static pressure to be high. .8 with both zones open. And 1.0 with one zone closed. Found a Damper motor to be binding. Pulled back the insulation and was able to freeze this. Found the bypass to not be functioning at all. Recommend replacing this. Found the debt sensor to be installed on the return Plenum. This should be in the supply. This was probably done by the builders to mask the airflow issues. The blower capacitor is testing 5.4 on a 7.5 and should be replaced as well. This system has minimal flood protection. The only flood protection in place is a drain pan safety switch. Recommend upgrading to a wet switch and adding an in-line drain safety switch. This is a measure to save the ceiling from water damage if you ever have a clogged drain issue. Moved outdoors and pressures in system are definitely showing lack of airfl
