Arrived on site to preform a 20 point maintenance inspection on a air handler/ Heat pump. Upon arrival unit was in heat mode, open up unit and took a total amp draw for the unit, amp draw was within the desired range for this unit. Inspected air handler control board, nothing was out of place all connections were tight and in the proper terminals. Temp rise was within limits and unit was not over heating. Checked and cleared condensate drains, drains were clear at the time of maintenance. Checked the outside unit, I opened the unit and took a compressor amp draw, compressor was within range, inspected all other electrical components and boards on outside inverter unit. Opened bar screen on outside unit and rinsed and clean entire unit. Unit was operating upon departure.
