What we did
The gas boiler serves three zones, and one was not heating. Air in the system was the cause. We bled all three zones, replaced the air bleeder and four caps, and then cleaned and vacuumed the inside of the unit.
The result
All three zones were heating and everything was working. The homeowner also signed up for a heating and cooling maintenance plan. Job completed October 21, 2026.
