Boiler Repair
in the Capital Region, NY

Look at the age and at what has failed. A circulator, zone valve or thermostat on a boiler that has otherwise been dependable is worth repairing, and a boiler around 10 years old with one failed part usually is. A cracked heat exchanger or a leaking, corroded boiler section is the other story: those failures are rarely worth fixing, especially on a boiler near 20 years old that has been calling for service every winter. You get the diagnosis, the flat repair price and a straight recommendation. See boiler replacement.

On a hot-water system the usual causes are trapped air, a failed circulator or a stuck zone valve. On steam it is often a stuck vent valve or a low water level. If one radiator is cold and the rest are hot, read why some radiators stay cold. If none are heating, call us.

Most home hot-water boilers read about 12 to 15 psi on the gauge when cold and rise a few pounds as the boiler heats, but systems differ, so check the label or manual. Pressure that keeps dropping means water is escaping, usually at a valve, a union, the relief valve or a failing expansion tank. Topping it up again and again only hides the leak. Pressure that climbs high or makes the relief valve discharge needs attention too. Steam boilers run at very low pressure and rely on the water level in the gauge glass instead.

Kettling, a banging or rumbling sound as the water heats, is usually mineral scale on the heat exchanger or boiler block. Gurgling points to trapped air, and banging pipes on a steam system are often trapped water (steam hammer) from a sagging pipe or a stuck vent. A boiler that fires and stops quickly (short cycling) can mean a control or sizing issue. Call us before the noise becomes a no-heat call.

It depends on what failed: a thermostat, zone valve or circulator costs less to fix than a leaking boiler section, and we diagnose before quoting. The quote is a single flat price, approved by you before work starts, with free estimates and no hourly meter. When replacing the boiler is the smarter spend we say that plainly; our heating replacement cost guide shows what drives it.

Boilers sit between the two trades, so use a company that does both. Boiler repair touches the burner and controls (heating) and the pipes, valves, pumps and pressure (plumbing). Our crew repairs boilers as well as plumbing, so one call covers a leaking union and a failed circulator. On paper that means City of Albany license #PLBG21-147, New York insurance, and the same family ownership since 2006.

A burner heats water in the boiler, or boils it into steam. A pump or the steam pressure sends that heat through pipes to radiators or baseboard, then the cooled water returns to be heated again. A thermostat tells the burner when to fire. Safety controls shut it down if pressure or temperature goes wrong.

Once a year, before the heating season, is the usual advice. A service visit checks the burner, controls, pressure, venting and safety devices. See our maintenance plan.

A stuck zone valve, a tired circulator or a thermostat swap can often be handled in one visit. A failed control, or a leak in the boiler section itself, takes longer and may turn into a replacement conversation. Either way you get the scope and the flat price first.

We give no-heat boiler calls priority for same-day visits Monday through Friday, 7:30am to 6pm. Call (518) 482-4205 and we will confirm the opening.

Our shop is in Nassau, NY (Rensselaer County), and boiler repair calls go out to Albany, Troy, Schenectady, Saratoga Springs, Rensselaer and the towns around them, in all 6 counties. Call (518) 482-4205 or book online to confirm the next opening; the Troy and Albany heating pages have the local details.

Yes, including the older cast-iron and oil-fired boilers that still heat homes in our region, as well as gas and propane units.

Call us if you’ve lost heat or hot water, see water or rust pooling around the unit, hear banging or rumbling “kettling” sounds, notice the pressure gauge keeps dropping, or get an error code on the display. In our hard-water area, mineral scale is a common cause of those noises, and catching it early keeps a small fix from becoming a no-heat emergency.
