Boiler, Radiator & Furnace Repair in Manchester, NH
Manchester heats with equipment other towns forgot how to fix. When the radiators go quiet on a January night, you want a licensed contractor who works steam and hot water every week — not one who learned on ductwork.
Call (603) 506-4389A City That Still Heats Like 1925 — and 1965, and 2025
Walk one block in the older wards and you'll pass every heating era New England has produced: one-pipe steam feeding cast-iron radiators, hot-water boilers pushing through baseboard added in a seventies renovation, gas furnaces in the postwar neighborhoods, and the occasional oil burner still holding out. The mill-era buildings were built around their radiators, and those systems — properly maintained — simply refuse to die.
What Manchester HVAC does is match the building to the right hands. Your no-heat call, banging pipes, or cold-radiator mystery goes to a licensed, insured contractor who diagnoses hydronic and steam systems routinely, states the price in writing before repairs begin, and treats a cold building — especially one with tenants in it — as the emergency it is.
What Goes Wrong When the City Gets Cold
- Radiators banging like a drum line — water hammer from trapped condensate, pitch problems, or a flooded boiler
- One apartment freezing while the rest bake — venting and balance in steam buildings, air-bound radiators in hot-water ones
- Boiler cycling on and off without heating — low-water cutoffs, failed feeders, and pressure controls doing their job for the wrong reason
- Furnace locking out on the coldest morning — flame sensors, igniters, and clogged filters picking their moment in the outer wards
- The gas bill that suddenly doubled — a system running constantly to overcome a fault nobody can hear
Heat Is Not Optional in a Rented Building
A meaningful share of Manchester's heating calls come from landlords, and the clock on those runs faster: tenants have a legal expectation of working heat in the cold months, and a no-heat complaint left to linger becomes a housing-standards problem on top of a mechanical one. The contractors we connect owners with treat occupied-building no-heat calls as first-priority work, document what they find and fix, and coordinate access with tenants directly when the owner is across town — or out of state.

Call (603) 506-4389Manchester Heating Questions
Do contractors still work on steam heat, or will they just push a replacement?
The ones we refer work on steam constantly — Manchester has too much of it for a serious city contractor to avoid. A steam system with a sound boiler is usually worth fixing properly: most 'failing' steam heat traces to venting, pitch, or near-boiler piping rather than the boiler itself, and those repairs cost a fraction of a conversion. A contractor who quotes a full replacement without explaining what's actually wrong with the steam side is answering a question nobody asked.
My radiators bang at night. Is the system about to fail?
Banging is water hammer — steam slamming into condensate that never drained back — and while it's hard on pipes and sleep alike, it's usually a correctable condition rather than a death sentence. Common causes in Manchester's one-pipe buildings: radiators that have lost their pitch toward the supply valve, a radiator valve left half-open (they only work fully open or fully closed), sagging mains, or a boiler flooded above its proper water line. A contractor can usually trace it in one visit.
We're a two-boiler building — one for each unit. Does that change service?
It mostly changes billing clarity, and it helps to say so when you call. Stacked flats and two-families in Manchester often run separate boilers with separate meters, which means the diagnosis needs to start at the right machine and the quote needs to name which unit's system it covers. Tell us which floor is cold and who owns the building, and the contractor arrives knowing which basement corner is theirs.
