Performed a heating pm on an oil furnace. Brushed and vacuumed. Replaced oil filter, nozzle, and strainer. Checked electrical connections and safety. Performed a combustion test. System is operating properly. The basement is a finished basement with the furnace in a mechanical room. There is not enough combustion air in the room. Recommend either leaving the door to the room open or bringing in combustion air from outside.
Upon arrival unit was off. Checked evap coil and saw a small buildup of ice. Took hot water and sprayed the coil until all ice was melted. Turned unit on and found the system was low on refrigerant. After getting customer authorization we chemically cleaned the condenser coil due to a high buildup of dirt and debris simulate higher pressures than the system actually had. Added 2 lbs 6 oz R410A to the system to bring the subcooling up to 13 from 1. Also added uv dye to the system. Pressures went from 75/270 to 130/366. Unit is working properly

Brushed and vacuumed flu pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Preformed combustion and smoke tests Upon arrival found the hi-vent over the boiler was dripping and appeared to have been leaking for some time. Was able to stop the hi-vent from leaking temporarily but when testing the boiler when the boiler temp was high the Extrol tank started leaking from the diaphragm seam. Had to drain system and replace the hi-vent and the Extrol tank. After replacing both we bled the air out of the system. Started and tested the boiler. The unit is operating properly.
