Boiler Service for Addison Homes with Radiator & Radiant Heat
Radiator heat is common across Addison's older housing stock, and it's a plumbing system as much as a heating one: water, pressure, pumps, and gas piping. Our licensed plumbers repair and replace hot water boilers, steam boilers, and the circulator pumps, zone valves, and expansion tanks around them. If your radiators are cold, banging, or the boiler keeps locking out, call 708-773-4149 — boiler no-heat calls get emergency priority in winter.
Boiler Repair, Replacement & Maintenance
Boiler Repair
Boilers fail in predictable ways: pilots and igniters quit, circulator pumps seize after decades of service, expansion tanks get waterlogged and send pressure climbing, relief valves start dripping, and air works into the loop leaving upstairs radiators cold. Every one of those is a standard boiler repair with a firm price quoted before work starts. If you're bleeding radiators every week or topping off pressure monthly, that's not normal — it's a symptom worth diagnosing.
Boiler Replacement & Installation
A boiler from the 1990s or earlier still limping along is costing you every month — modern high-efficiency units squeeze far more heat from the same gas. Boiler replacement done right starts with a heat-loss calculation so the new unit is sized to your home, not guessed at. Oversized boilers short-cycle and die young. We handle the full swap: old unit out, venting and gas piping brought to code, new boiler commissioned and balanced so every radiator actually gets hot.
Annual Maintenance & Tune-Ups
Annual boiler maintenance is the cheapest heat insurance there is: we clean the burner, check the heat exchanger, test safety controls and the relief valve, verify pressure and expansion-tank charge, bleed air from the loop, and inspect the venting. Fall is the right time — before the first hard freeze exposes the weak link. Ask about a maintenance visit when you call 708-773-4149.
Radiant Floor & Baseboard Heat
Hydronic baseboard and radiant floor systems run on the same principles as radiator heat — a boiler, a loop, and circulation. We repair leaking baseboard elements, replace failed loop circulators, balance zones that never seem to warm up, and tie new radiant zones into existing boilers where the system can support it.
Warning Signs Your Boiler Needs Attention
- Radiators cold on the top floor (air in the lines) or cold everywhere (circulator pump)
- Banging, kettling, or rumbling from the boiler — sediment or circulation trouble
- Pressure gauge creeping above 25–30 psi or repeatedly dropping to zero
- Water pooling under the boiler or a relief valve that drips constantly
- Pilot or ignition lockouts that need resetting more than once a season
- Gas bills climbing while the house never quite feels warm
Any of these is worth a call before it becomes a January emergency: 708-773-4149.
Boiler Questions from Addison Homeowners
A hydronic system is sealed — if pressure keeps dropping, water is leaving somewhere: a weeping relief valve, a pinhole in the piping, a failing expansion tank, or a leak inside the boiler itself. Topping it off weekly hides the symptom while the leak does damage. It's worth a proper diagnosis.
Cast-iron boilers routinely run 20–30 years with annual maintenance; modern high-efficiency condensing boilers average 15–20. If yours is past 20 and needing repairs most winters, put the repair money toward replacement — the gas savings from a modern unit do part of the math for you.
Usually one of three things: air trapped in the lines (radiators need bleeding), a failed circulator pump, or a stuck zone valve. Cold radiators on the top floor point to air; cold everywhere points to the pump. Either way it's a standard diagnosis and usually a same-day fix.
Yes — no-heat calls in freezing weather get priority dispatch, nights and weekends included. A house with no heat in January risks frozen pipes on top of the cold, so call the moment the boiler quits rather than waiting for morning.
