Heating Repair, Install & Replacement in Poughkeepsie, NY

Called out for a no-heat complaint on a mid-2000s Weil-McLain gas boiler — homeowner said it had been cycling on and off all week. Found the pressure relief valve weeping and the system running low on water pressure, hovering around 5 PSI when it should sit at 12-15. Traced it back to a failed fill valve that had stopped auto-feeding the system. Swapped the fill valve, brought pressure up, purged air from the zones, and fired it through three full cycles. Heat holding steady before I left.
