Arrived on site to perform condensation diagnostic on 1989 system. Upon arrival Gary stated That he has recently done repairs to the system it has swapped out the indoor blower motor and filter. Thermostat was also swapped out. He is now seeing that the primary drain line connecting to the washer drain out is leaking. Prior to the leak he had done in evaporator coil cleaning himself. Inspected primary line and found that there was a cut through on the back of the pipe which is resulting in it leaking. It is possible that someone tried to cut the pipe in the past or it has rub through the corner. Gary stated that debris was inside of the rubber hose possibly causing it to back up. Gary would like to hold off and repairs at this time and try to fix it himself. Also would like to hold off on maintenance plan at this time. Upon departure client will be fixing PVC line himself.

Upon arrival performed maintenance on Goodman unit. Outdoor system has a very high start up for compressor. Advised adding a booster can help out on start ups. Outdoor circuit board has a very big burnt spot on terminals.primary & secondary motor control are in range. Condenser fan motor in range.

Arrived on site to perform a leak dye inspection/maintenance on 2011 American standard heat pump. Upon arrival Karen states that I do not use the system much and did not even realize that the system is not working properly. Initially started system and system turned on but was short cycling on and off. Measured refrigerant pressures in Falmouth the system was significantly low on R410a refrigerant charge again. Sound refrigerant leak present on King valve suction line indicating that this is where all the Refrigerant is being lost. Kingvalve will have to be replaced and Cost of repair will be sent over. At this time Karen is aware that the system is leaking and low again But would like to hold off on any repairs at this time because they do not use it and are not in a position to fix it. They will give us a call when they’re ready to use the system and possibly fix or replace upon departure system is significantly low on refrigerant charge

Arrived on site and performed AC diagnostic on two system Lennox from 2007. Upon arrival Tony stated that the FAU breaker keeps tripping and the AC breaker keeps tripping for both units. Turned on downstairs system and proceeded to outdoor unit and found suction line was freezing over within two minutes. Proceeded to attic and found the indoor blower motor has failed and is no longer blowing air over the evaporator coil causing freezing temperatures. Installed new dual secondary motor control but motor is still over amping due to old age and wear and tear. Proceeded to outdoor unit for downstairs and found the system was slightly low on R22 charge and the dual secondary motor control was out of range. Began diagnostic on upstairs system and found that it was operational at this time although electrical components were not in good condition unfortunately. Dual secondary motor control Was also out of range and starter was severely burnt and pitted on contact points from high power usage.
