What the homeowner reported

The homeowner called for the yearly oil burner maintenance before the heating season.

What we found

The burner needed its cleaning, and two of the system's air bleeders were no longer working properly. The record also notes that the burner's top head was hard to open and worn.

What we did

Waseem cleaned the burners and serviced the oil filter, replaced the two air bleeders, cleaned up the system and refilled it with fresh water. The maintenance covers checking power, the thermostat and wiring, inspecting for oil leaks, cleaning the burner head and electrodes, testing the burner motor, vacuuming the combustion chamber and testing the safety controls.

The result

Everything was working well at the end of the visit. For the next maintenance, the record recommends a spin-on oil filter and a new burner top head.

About oil boiler tune-ups

Oil burners leave soot behind, and soot on the boiler's heating surfaces acts like insulation, so more oil goes up the chimney instead of into the water. A yearly tune-up with a new nozzle, a filter service and a cleaning keeps the flame clean. Air bleeders on the piping let trapped air escape; when they stick, rooms on that loop can heat poorly.
