Performed the heater tune-up on two Carrier heat pump systems. Checked electrical, mechanical and performance systems of the units. Cleared, cleaned, flushed and treated the drain line and cleaned the exterior of the air handler. Replaced all filters for the homeowner and sealed them with tape to prevent any air bypass. I verified static pressure is within range on both systems. Secured the compressor wiring at both outdoor units. I did find the outdoor capacitor for the system that controls the bedrooms was below value. Homeowner chose to have the capacitor replaced at this time. I replaced the outdoor capacitor for the system that controls the bedrooms and the cycled power. Both systems are operational at the time of departure.
