11-3-20 (Frank) 1 system heating inspection. Heat pump, heat strips, and cooling all passed (form with pictures included). Cleaned up a few items, used primary drain treatment with approval, Cleaned outdoor contactor, washed outdoor fins, primary air filter, secured insulation on large copper line (indoor and out). ***primary finding is that filter at unit needs to be cleaned more often, this is the first, thinner filter at the Clean Effects (pictured in report). Excess buildup makes the system work harder, and The pressure causes some debris to go “around†the filter and on the coil. Coil already has some debris (pictured). Rebecca Scott said they may address indoor coil cleaning in the springtime.
