Repair of residential gas and electric boilers and hydronic heating systems — no-heat calls, kettling, lockout codes, circulator-pump failures, and pressure problems on radiator and baseboard loops, diagnosed flat-rate and fixed from a stocked truck.
Boiler Repair is one part of our water heater services coverage in Louisiana. For the full picture — symptoms, costs, and when to repair vs. replace — start with the complete Water Heater Repair guide, or browse every water heater services service we offer.
A boiler is a different machine from a water heater: it heats the water that runs through your radiators, baseboards, or in-floor loops, and when it fails the symptom is a cold house, not a cold shower. Boiler repair is its own discipline — combustion and venting on the fire side, pressure, circulation, and air elimination on the water side, and a controls chain of thermostats, zone valves, and safeties in between. We service residential gas and electric boilers across Louisiana with flat-rate diagnosis and the common failure parts on the truck.
Most no-heat calls come down to a short list: an ignition or pilot fault, a seized circulator pump, a stuck zone valve, a tripped high-limit, or system pressure that's drifted out of range. We work the chain methodically — verify the call for heat, confirm the burner fires, check pressure and circulation, and isolate the failed component — then quote the fix in writing before touching a wrench in the Louisiana home.
Hydronic systems also fail slowly: kettling from scale on the heat exchanger, radiators that need bleeding every week from air ingress, or a expansion tank that's lost its charge and lifts the relief valve. Those are repairable conditions, and catching them early protects the boiler itself. We repair, descale, repressurize, and rebalance systems across Louisiana — and we'll tell you honestly when a cracked heat exchanger means the boiler is done.

Is it time for boiler repair? The signs
Radiators or baseboards stay cold
A cold zone with the thermostat calling means a circulator, zone valve, or air-lock problem; a whole-house no-heat points at the boiler itself. Either way it's a diagnosable Louisiana repair, not a guess.
A boiler that rumbles like a kettle has scale insulating its heat exchanger, making it overheat the water locally. Descaling stops the noise and the efficiency loss in the Louisiana system.
Lockout or error codes
Modern boilers lock out on ignition, flame-sense, and safety faults and show a code. We read it, fix the actual cause — igniter, sensor, venting — and clear it on the Louisiana visit.
Pressure gauge out of range
Hydronic systems run in a narrow pressure band; too low and upper floors lose heat, too high and the relief valve drips. Both trace to fill valves, expansion tanks, or leaks we repair across Louisiana.
Radiators need constant bleeding
Air returning week after week means the system is pulling it in somewhere — a failing air eliminator, a weeping fitting, or low pressure. Fixing the cause ends the Louisiana bleeding ritual.
The causes we see & fix most
Scale on the heat exchanger
Hard water bakes mineral scale onto the exchanger, causing kettling and local overheating. A descaling flush restores quiet operation for the Louisiana boiler.
Circulator pump wear
The circulator runs thousands of hours a season and eventually seizes or leaks at the flange. It's the most-replaced hydronic part in Louisiana, and we stock common sizes.
Ignition and sensor faults
Igniters, thermocouples, and flame sensors age with every cycle and eventually fail to prove flame, locking the boiler out. Replacement is a same-visit Louisiana fix.
Expansion tank losing its charge
A waterlogged expansion tank spikes system pressure every heating cycle and lifts the relief valve. Recharging or replacing it protects the whole Louisiana loop.
Air and slow leaks
Weeping valve stems and fittings let water out and air in, corroding the loop from inside. Finding and sealing them ends both the pressure loss and the cold Louisiana radiators.

Frequently asked about boiler repair
Top questions homeowners searching for Boiler Repair near me ask us:
How much does boiler repair cost in Louisiana?
Flat-rate by the failed component — an igniter, circulator, zone valve, or expansion tank each carry a fixed price we quote in writing before starting. Diagnosis across Louisiana is a flat fee, waived when you proceed with the repair.
Do you service all boiler brands?
The major residential lines — Weil-McLain, Burnham, Navien, Bosch, Slant/Fin, and similar gas and electric models across Louisiana. We carry universal igniters, sensors, and circulators for same-visit fixes.
Boiler or water heater — which do I have?
If the unit feeds radiators, baseboards, or in-floor heat, it's a boiler; if it feeds your taps and shower, it's a water heater. Some Louisiana homes have both. This page is for boilers — our water heater crews handle the tap-water side.
My boiler is locked out — what should I do?
Power-cycle it once; if it locks out again, leave it off and call. Repeated relights against an ignition fault can soot the burner and turn a sensor swap into a bigger Louisiana repair.
When is replacement smarter than repair?
A cracked heat exchanger, a rotted-out shell, or a 25-year-old unit needing its third major part — at that point we say so and quote a replacement honestly. Everything else on a Louisiana boiler is usually worth repairing.
