Boiler Repair and Replacement in Winnetka

If your Winnetka home heats with a hot-water or steam boiler and radiators, our technicians can keep it running safely and efficiently. We repair and maintain boilers of all makes, and we install new boilers from Dunkirk, Laars, Peerless, Burnham, Crown, Weil-McLain, Pennco, NTI, Navien and Raypak. When an older system is costing more in repairs than it’s worth, we’ll give you an honest assessment and a free estimate on a replacement. Learn more about our boiler services.

Signs your boiler needs attention

Rooms or radiators that stay cold
Pressure that keeps dropping or a relief valve that drips
Banging, gurgling or new noises
Leaks around the boiler, pipes or radiators
Rising gas bills without a change in use

Read our guides on why boiler pressure drops and what drives boiler replacement costs.

Cooling for Homes Without Ductwork

Boiler-heated homes often lack ductwork for central air. Ductless mini-splits add efficient cooling (and supplemental heat) room by room, and radiant floor heating is a comfortable option for kitchens, baths and additions.
