Radiators cold on one floor
Air trapped in the lines, a stuck zone valve or a failing circulator pump usually explains a hot-water system that heats unevenly.
Boiler RepairNiles sits on the St. Joseph River just above the Indiana line, and its mix of older in-town houses and newer subdivisions keeps our technicians busy with boilers, furnaces and central air.

Homes in Niles 49120 are served by our Coloma office, which handles the southern half of Berrien County along with the lakeshore towns. Vans head down to Niles on planned routes during the day, and a no-heat call in January moves ahead of routine visits. You talk to a person when you call, and that person gives you a realistic arrival window instead of a vague promise.
Most of our Niles work falls into three groups: hot-water and steam boilers in older houses near downtown, gas furnaces with central air in the subdivisions, and propane equipment on the rural roads outside the city. Each system has its own failure points, so we stock the trucks for all three. The technician explains what failed, what it costs to fix and what the other options are before any work starts.
The older streets around downtown Niles hold two-story houses that were built for radiator heat, and many still run on a hot-water boiler in the basement. Some owners added a forced-air furnace later for central air, which leaves two systems sharing one house. Our boiler repair visits cover circulator pumps, expansion tanks, zone valves and relief valves, and we can tell you whether an aging cast-iron boiler still has years in it.
Out toward the edges of the city, newer subdivisions mostly use high-efficiency gas furnaces paired with a central air condenser, often installed as a set when the house was built. Those systems are now reaching the age when igniters, inducer motors and capacitors start to wear out. Homes on country roads beyond the city often heat with propane, and a few pair that furnace with a heat pump. We work on every one of these setups from the same trucks.

Niles sits far enough south and inland that it misses the worst of the shoreline snow bands, but the river valley still holds cold air on still winter nights. Boilers and furnaces run long cycles through January and February, and a weak circulator or a dirty flame sensor tends to fail on the coldest morning. Summers along the river turn muggy, so central air units work hard from June into September and dirty outdoor coils lose capacity quickly.
Niles falls under the Coloma office at 340 Washington St., so the vans that come down to the river are already working in Berrien County. Call (269) 360-5258 at any hour, including nights and holidays, and someone on our team picks up. Tell us what the boiler or furnace is doing and whether anyone in the house is at risk from the cold, and we route the nearest technician.
Common calls

Boiler RepairA waterlogged expansion tank or a leaking fill valve can push pressure up until the relief valve drips.
Radiator & Steam Heat ServiceNewer high-efficiency furnaces shut down on a blocked condensate drain, a weak inducer or a dirty flame sensor.
Furnace RepairA worn capacitor or contactor on the outdoor unit is the most common reason a system stops cooling on a hot afternoon.
AC RepairGas tank heaters in older basements often rust through, and we replace them with a tank or tankless unit.
Water Heater Repair & ReplacementFAQ
Yes. Many houses near downtown Niles still heat with a hot-water boiler and cast-iron radiators. We repair circulators, zone valves, expansion tanks, relief valves and burners, and we bleed trapped air from the lines. If the boiler is near the end of its life, we explain replacement options that keep your existing radiators in place.
Niles is covered from our Coloma office at 340 Washington St., which handles Berrien County calls. Vans travel down on regular routes during the day, and no-heat emergencies in winter go to the front of the line. The same phone number, (269) 360-5258, reaches the dispatcher for Niles at any hour.
Most boiler repairs in Niles land between $213 and $687. Bleeding air and replacing a relief valve sit near the low end, while circulator pumps, expansion tanks and gas valves cost more. The technician inspects the boiler first and gives you the price before any repair begins, so you can decide with real numbers.
