Performed a heating pm on an oil boiler. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Started and checked the safeties. Performed a combustion test. 5.2%o2, 2 ppm, 0 smoke, 82.8% efficient System is operating properly. The circulator gaskets have corrosion on them from a previous leak. Recommend replacing them. Also the pipe on the boiler for the hi-vent is corroded from a previous leak. Recommend replacing the pipes before they start leaking.

Upon arrival unit was at 20 psi and the pressure relief was dripping. This indicates the diaphragm of the pressure relief was going bad and allowing water to leak by. Drained pressure from the system and replaced the pressure relief. When the system was empty we found that the pressure gauge was stuck at 19 psi. After getting customer authorization we replaced the temp/pressure gauge. Filled system back up with water and bled all 3 zones. Started and tested the boiler. Had hot water coming back on all 3 zones. Unit is working properly. Unit was at 20ppm when leaving

Performed a heating pm on an oil boiler. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Started and checked the safeties. Performed a combustion test. System is operating properly. The pressure relief valve has a slow drip. Found the extrol tank is going bad and water has leaked past the diaphragm into the air side of the tank. Recommend replacing both the extrol tank and the pressure relief valve. There is some corrosion around the domestic coil gasket from a previous leak. Recommend replacing the gasket. Isolated the boiler and drained the pressure from the system. Replaced the extrol tank and pressure relief valve. Filled and checked for leaks. Opened the valves and started the system.

Checked thermostats upstairs. Switched 2 of them temporarily to test. After removing the ones that did not work for approximately a minute, they powered down and rebooted. The thermostats started working. Turned them on individually to check the damper operation. Did the same for the thermostat downstairs that did not work. Currently all 6 thermostats are operating properly. The zone system is a Trane Intergrated system which is older.

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

Upon arrival I found the unit had no power. Found no breakers were tripped or off. The upstairs breaker was on. I only had 120 coming in but coming out. It’s a breaker. Customer needs to call an electrician. Switch is off at the unit. Customer would like the invoice mailed.

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.
