Licensed plumbers, written pricing, serving Yonkers
Yonkers runs on hydronic heat: prewar buildings and older multifamily homes across the city heat with cast iron radiators and baseboard loops fed by a gas or oil fired boiler, and many of those boilers are decades past their efficient life. Action Construction is the licensed plumbing contractor that installs and repairs the boiler itself and everything piped to it in Yonkers, NY, working on Weil McLain, Burnham, Navien, Peerless, and Lochinvar systems. We are not a fuel dealer. We are the plumber for the boiler.
Boiler work is the water side of a heating system:
A search for boiler help in this area turns up a mix of oil companies and general heating firms, and the oil companies in particular tend to focus on the burner and the fuel rather than the piping. We are the licensed plumbing contractor that installs the boiler itself and everything connected to it, and we service gas and oil fired hydronic systems whoever delivers the fuel.
Boiler replacement is worth planning rather than waiting for a January failure. Signs a boiler is near the end include age past twenty to twenty five years, rust or weeping at the sections or the tankless coil, short cycling on and off, uneven heat between zones, visible corrosion on the near boiler piping, a flooded or waterlogged expansion tank that keeps tripping the relief valve, and rising fuel use for the same comfort. A boiler that fails in a cold snap is an emergency replacement at a premium, with no time to run a load calculation or match the venting properly, so the better path is to replace a tired unit in the spring or fall shoulder season.
When we quote a replacement we size the new unit to a room by room heat loss calculation, not just match the old nameplate, because most older Yonkers boilers were significantly oversized and a right sized modern unit cuts fuel use and short cycling both. We also rebuild the near boiler piping to the manufacturer’s specification rather than reconnecting old, corroded piping to a new boiler, because that piping, the circulator placement, the air separator, and the expansion tank are what protect the new unit and keep the zones balanced. On a high efficiency condensing boiler that means primary secondary piping or a low loss header so the boiler always sees its minimum flow. The written price covers the boiler, the near boiler piping, a new expansion tank and circulator as needed, the venting or a chimney liner where the old atmospheric unit is replaced, the permit, and the City of Yonkers inspection.
A share of the older multifamily buildings and larger prewar homes in Yonkers still run on one pipe or two pipe steam rather than hot water. Steam is a different animal: the near boiler piping, the Hartford loop, the equalizer, and the header have to be built to the manufacturer’s diagram or the new boiler carries water over into the mains and hammers. We replace steam boilers, skim the new one properly on startup, set the automatic water feeder and the low water cutoff, and sort out the failed radiator vents and main vents that are usually behind uneven heat and banging. Sizing a steam boiler is done by measuring the connected radiation, not by a heat loss calculation, and getting that wrong is why so many replacement steam boilers never run right.
Repairs include
We carry common parts for Weil McLain, Burnham, Navien, Peerless, and Lochinvar, so a single visit fixes most no heat calls rather than turning into a parts order and a cold weekend. If your hot water comes off the boiler through an indirect tank or a tankless coil, that work ties into water heater installation and water heater repair, and the full list is on our Yonkers plumbing services hub.
A hydronic boiler benefits from a yearly service before the cold arrives:
Most no heat calls in January trace back to a fault a fall service would have caught, a waterlogged expansion tank, a tired circulator, a sticking zone valve, a plugged condensate trap on a high efficiency unit, or a control drifting out of range. The service visit is a few hundred dollars against a holiday weekend emergency rate and a cold house, and for an oil unit it also keeps the burner tuned so the fuel bill does not creep up over the winter. For a building with tenants, a documented annual service also supports the landlord’s duty to provide heat under the city and state housing rules, and we can put a multi unit building or a portfolio on a schedule so every boiler is checked on the same visit each fall.
Yes. The boiler and its water side piping, circulators, zone valves, and expansion tank are plumbing work. A licensed plumbing contractor is the right call for a boiler installation, a leak, or a no heat problem on a hydronic system, and we coordinate with your fuel supplier on the burner side of an oil unit where that split applies.
It depends on the fuel, the size, whether it is a cast iron or a high efficiency condensing unit, and how much of the near boiler piping and venting needs rebuilding. We provide a written installed price after a heat loss calculation, including the permit and inspection, before any work begins. Yonkers permits locally, so an NYC replacement figure is not a reliable guide here.
Many boiler problems are component repairs: a circulator, a zone valve, an aquastat, a low water cutoff, a feed valve, or a relief valve. A boiler that is leaking from the cast iron sections themselves, or is past twenty five years old and short cycling, is usually a replacement. We give you both paths with prices.
Weil McLain, Burnham, Navien, Peerless, and Lochinvar, in gas and oil fired models, for baseboard, radiator, and radiant systems. We help you choose based on your existing distribution, your fuel, whether the chimney or sidewall can support a condensing unit, and whether an indirect tank off the boiler is the better way to make hot water than a separate heater.
Usually not the boiler itself. A single cold zone points at a stuck zone valve, a failed circulator on that loop, an air bound line that needs bleeding, or a balancing problem. All of those are repairs we handle, and we diagnose which one it is before quoting rather than replacing parts in sequence.
