No Heat & Heating System Help in Westford, MA

Identify steam or hot-water distribution first. Connected steam radiation, hot-water heat loss, domestic hot-water demand, venting, utilities, and space then shape the equipment choice.

The four paths below cover combi equipment, standard steam or hot-water boilers, condensing hot-water boilers, and radiant-floor distribution. Furnace work is limited to conditions that fit our licensed plumbing and gas scope, with compatibility confirmed by phone.

Confirm whether the whole house or one zone is cold, then note the thermostat, fault code, sounds, visible water, and gauge without opening equipment.

You may replace thermostat batteries and check the normal switch and labeled breaker once. Never bypass a safety, relight a burner, or keep pressing reset.

Observe an accessible vent or condensate termination from a safe position. Do not climb, dismantle piping, use flame, or force ice free.

An ignition lockout means the control stopped firing because a required condition was not proven. Preserve the code; repeated resets can hide ignition, flame-sensing, venting, fuel, or control evidence.

Low hot-water boiler pressure may point to a leak, trapped air, expansion, relief discharge, or a feed-control fault. Steam pressure and water-level controls require their own checks. Do not apply a hot-water pressure target or repeatedly add water to a steam boiler.

A frozen or blocked condensate path can stop a condensing boiler that cannot drain safely. A torch, open flame, or uncontrolled heat near plastic piping is not a safe fix.

A failed circulator can leave the boiler hot while a zone stays cold. Closed valves, trapped air, relays, and zone valves can look similar, so power and water movement must be compared.

Thermostat and zone-valve faults often affect one area or leave a zone active. We trace the call through the thermostat, wiring, panel, actuator, and circulator before naming the failed part.
