Boiler Trouble Signs
Hydronic systems are quiet workhorses — until they aren't. These are the signals that earn a service call:
Seeing one of these? Skip the guesswork — call now and describe it. A same-day look beats a cold house.
Call NowCall (877) 701-0450No heat, or heat in only part of the house
A dead circulator pump, a failed zone valve, or air locked in the loop. Half-warm systems are usually a zone problem; fully cold ones start at the boiler itself.
Pressure reading wrong
Residential boilers typically live at 12–15 psi cold. Pressure near zero means a leak or feed problem; climbing past 25 psi points at the expansion tank or fill valve — and the relief valve dripping is that story's ending.
Kettling — a rumble like a giant kettle
Scale on the heat exchanger making steam where it shouldn't. It's inefficient, hard on the exchanger, and fixable — a flush and treatment beats an exchanger replacement every time.
Radiators cold at the top
Air in the system. Bleeding radiators is a homeowner job (top-floor first); if they need it monthly, the system is drawing air somewhere and that's the real fix.
Water under the boiler
Relief valve, pump seal, or a failing exchanger — in every case, worth a same-day look. Hydronic leaks never improve on their own.
Short-cycling
A boiler firing in quick bursts wastes fuel and wears components. Causes range from a waterlogged expansion tank to an oversized boiler — diagnosable in one visit.
Boiler Service & Repair — What a Visit Covers
A proper boiler service isn't a glance and a sticker: combustion analysis on gas models, heat exchanger inspection, pressure and expansion tank check, relief valve test, circulator and zone valve operation, and bleeding air from the loop. On repairs, the diagnostic walks the same path to the failed component, and you get the quote before the work.
Radiant floor systems get their own attention — manifold balancing, loop temperatures, and mixing valve checks — because a radiant system out of balance wastes its whole comfort advantage.
Boiler Not Working? What We Check First
No heat with the boiler running is almost always circulation: a dead circulator pump, a zone valve that won't open, or air locked in the loop. No heat with the boiler silent starts at ignition — pilot or electronic ignition, a flame sensor, a safety or pressure switch, or the gas supply itself. The diagnostic walks that list in order, and most boiler repairs finish in the same visit.
Leaks, pressure drift and kettling get the same treatment: find the component, fix the component, and confirm the system holds pressure and heats every zone before the truck leaves. Every gas boiler repair ends with a combustion and carbon monoxide check.
Frequently Asked Questions
Why is my boiler running but the radiators are cold?
Usually circulation, not combustion: a failed circulator pump, a stuck zone valve, or air locking the loop. If only the radiator tops are cold, bleed them — air rises. A boiler that heats its own pipes but not the house is a same-day diagnostic.
What pressure should my boiler be at?
Most residential systems: 12–15 psi cold, up to around 20 psi hot. Near zero means a leak or feed valve problem; over 25 psi points to the expansion tank or fill valve, and the relief valve will start discharging to protect the system.
Why is my boiler making a rumbling noise?
That's kettling — mineral scale on the heat exchanger flashing water to steam. It's fixable with a system flush and treatment, and worth fixing promptly: sustained kettling shortens exchanger life, which is the expensive part.
How often should a boiler be serviced?
Annually, ideally before heating season. Combustion analysis, exchanger inspection, pressure and safety checks — the best-value maintenance a hydronic system can get.
Why is my boiler not working?
Start with the simple checks: thermostat calling for heat, boiler power switch on, pressure gauge in its normal band, pilot or ignition sequence starting. No heat with the boiler running is usually circulation — a circulator pump, zone valve or airlock; no heat with the boiler silent points at ignition, a safety switch or the gas supply. Both are same-day local boiler repair.
Repair or replace the boiler?
Past 15–20 years old, or with a failing heat exchanger, replacement usually beats repair — you'll see both options side by side and the decision stays yours.
Do you work on radiant floor heating?
Yes — manifold balancing, circulators, mixing valves, and loop diagnostics for hydronic radiant systems, plus the boilers that drive them.
