Performed preventative maintenance on a LENNOX heat pump. Model number: 16HPX-036-230A01. Serial number: 1919F00280. Upon arrival the unit was on. I adjusted the thermostat to make sure it will run. Went downstairs to the unit and watched it run. Turned the unit off at the switch. Removed the panels. Checked the electrical connections to make sure they are properly secure. Checked the evaporator coil for any dust build up. Poured water into the condensate trap and watched it drain properly. Poured water into the condensate pump and watched it pump out properly. Changed the 16x25x4 filter supplied by the homeowner. Took an amp draw of the fan. Running within the manufacture’s specs. Placed the panel back in the unit and watched it run. Went outside to the condenser and watched it run. Checked the coils for any dirt build up. Removed the panel and brushed out any spiderwebs. Checked the contactor and capacitor. Capacitor is a little low and I recommend replacement soon. Took an amp draw
