One radiator stays cold
A stuck or clogged air vent usually stops steam from entering. We replace the vent and check the radiator's pitch.
Radiator & Steam Heat ServiceStuart's late 1800s Queen Anne and Italianate houses were built around heat that rises from a basement boiler, and keeping that steam system healthy takes a technician who knows how it works.

The Stuart historic district sits northwest of downtown Kalamazoo, with homes dating to the late 1800s. Many still heat with steam: a boiler in the basement boils water, and the steam rises through iron pipes to radiators in every room, then condenses and drains back. When it is balanced and maintained, steam heat is even, quiet and very long-lived. Neglected, it wastes gas and leaves some rooms cold.
Our technicians repair and maintain steam boilers, replace radiator and main vents, adjust pressure controls and test low-water cutoffs. We also help Stuart owners add cooling without cutting into plaster and trim, using ductless systems placed with care. The goal is to keep the house comfortable while respecting how it was built, and to explain each step so you understand your own system a little better after every visit.
A one-pipe steam system uses the same pipe to send steam up and return water down, so the pipes must keep their slope back toward the boiler. When a floor settles or a radiator tips, water pools and the system starts to bang. Each radiator has a small air vent that lets air out as steam arrives, and the main lines in the basement have larger vents. Failed vents are the most common reason one room stays cold while the rest of the house is warm.
The boiler itself needs its water level watched. A sight glass shows the level, an automatic or manual feed adds water, and a low-water cutoff shuts the burner down if the level drops too far. Steam boilers also run at very low pressure, usually well under two pounds, and a pressure control set too high causes uneven heat and short cycling. Our radiator and steam heat service covers all of these checks.

Steam systems shine on the coldest nights. Once the radiators are full, the cast iron holds heat long after the burner stops, which makes for steady warmth when lake-effect snow blows through and temperatures fall below zero. Summer is the hard season for these houses, since there is no ductwork for central air. Humid July afternoons push owners toward window units, and a carefully placed ductless mini-split gives quieter, more even cooling without new duct chases.
Stuart is just northwest of our downtown Kalamazoo office, so a technician can usually be there quickly. A person answers (269) 360-5258 at all hours, including nights and holidays, which matters when an old boiler locks out in a cold snap. We diagnose first and tell you the price before any repair. For a new boiler or ductless system, the estimate visit has no charge.

Radiator & Steam Heat ServiceWater pooling in a sagging pipe or main causes water hammer. Our technicians find the low spot and correct the slope or venting.
Radiator & Steam Heat ServiceWe test the low-water cutoff, check for leaks and clean the sight glass so the boiler runs safely.
Boiler RepairDuctless heads placed on interior walls or high in a room cool the house while leaving its original details intact.
Ductless Mini-Split InstallationWe size a new steam boiler to the radiators in the house, not just the old boiler's label, so the system heats evenly.
Boiler Installation & ReplacementFAQ
Banging usually means water is trapped in a pipe that has lost its slope, and steam slams into it on startup. Settled floors, tipped radiators and failed main vents are common causes in older homes. Our technicians find where the water sits and correct the pitch or venting, which typically quiets the system.
A new gas steam boiler for a historic Stuart home usually runs between $7,840 and $13,960 installed, depending on the radiator load, the near-boiler piping and venting work. Sizing is done by measuring every radiator in the house. We give you a written price after that survey.
Yes. Ductless mini-splits need only a small wall opening for each indoor head, and the line set can run along the outside or through closets. We plan the head locations with you to avoid covering trim or plaster details, and one outdoor unit can serve several rooms.
