Boiler Repair
No heat, a leak, or a boiler making a noise it never used to? Williams Energy repairs oil, gas, and propane boilers across the South Shore, with 24/7 emergency service when the cold will not wait.
Boiler repair always seems to come up on the coldest morning of the year. When your boiler stops making heat, starts leaking, or makes a sound it never used to, Williams Energy is ready, with 24/7 emergency service across our service area. We have repaired oil, gas, and propane boilers on the South Shore since 1919. Because a boiler involves water, pressure, and circulation rather than simple forced air, a good diagnosis takes a trained eye, and that is what our technicians bring to every call.
Common Boiler Problems We Fix
Boiler trouble shows up in more ways than a furnace, because there is water and pressure in the mix. These are the issues we see most across South Shore homes.
No Heat at All
A failed thermostat, circulator pump, or ignition can leave the whole system cold. We trace it to the real cause fast.
No Hot Water
On combi and indirect systems, a boiler fault can take your hot water down with it. We get both back.
Leaks or Dripping
Water around the boiler points to a failing seal, valve, or pressure problem, and it rarely fixes itself.
Low Boiler Pressure
A pressure gauge that keeps dropping usually means a leak or a faulty expansion tank, and the boiler may lock out.
Banging or Kettling
Rumbling and banging sounds often mean sediment or limescale has built up on the heat exchanger.
Cold Radiators
Radiators cold at the top or cold in just one room often need bleeding or signal a circulation problem.
Pilot or Ignition Failure
A boiler that will not fire is frequently an ignition, sensor, or gas-supply issue we can pinpoint quickly.
Circulator Pump Problems
The pump moves hot water through your home. When it fails, heat stops reaching the radiators or baseboards.
Hearing Banging or Kettling?
That rumbling, kettle-like sound usually comes from sediment and limescale on the heat exchanger, which traps water and lets it overheat. It is worth addressing early, because the buildup makes the boiler work harder and wear out sooner. A flush or descale often quiets it down, and our technician will tell you whether that is all it needs.
24/7 Emergency Boiler Repair
A boiler does not wait for business hours to fail, and a no-heat house in a South Shore January is not something to sit on overnight. We answer around the clock, so when the heat or hot water goes out, you reach a local team that can respond instead of a recording. For homes with older residents or young kids, that fast answer is the reason a lot of people keep our number on the fridge.
How We Get Your Heat Back
No mystery, no runaround. Here is what happens from your call to a warm house.
You Call, We Answer
Day or night, you reach a person, not a queue. We get the details and schedule fast, with emergency response when there is no heat or hot water.
We Find the True Fault
Water, pressure, and circulation make boilers trickier than forced air. We diagnose the actual cause rather than swapping parts and hoping.
You Get Upfront Pricing
We tell you what the repair involves and what it costs before we start, so there are no surprises when the work is done.
We Repair and Test
We complete the fix, then run the system and check pressure and heat across the home before we pack up and leave.
Repair or Replace?
A good boiler can run for decades, so a single repair on an otherwise healthy unit is almost always worth it, and we will tell you when that is the case. But some faults change the math. A cracked or leaking heat exchanger, or a boiler past the 20-to-30-year mark that keeps needing parts, is usually telling you it is time.
We give you the honest call and walk you through a new boiler installation only when it genuinely saves you money over the long run. And a service plan keeps small problems from turning into a cold morning in the first place.
Every Boiler, Any Fuel
We repair boilers of every brand, no matter who installed yours, on all three common fuels.
If your home heats with a furnace instead, our furnace repair team handles those, and our heating system repair covers whatever else keeps your house warm. One call reaches the team for all of it.
Why the South Shore Calls Williams
Plenty of our steadiest customers first called us on a cold morning with a dead boiler and stayed for the service that followed. Boiler repair is one part of our full heating and cooling lineup, all handled by the same local team rather than a rotating cast of subcontractors who do not know your home.
Here is why neighbors choose Williams, or contact us the moment your boiler acts up.

Boiler Repair Questions, Answered
Do you offer 24/7 emergency boiler repair?
Yes. We provide round-the-clock emergency boiler repair, not just during business hours. When your heat or hot water goes out in the middle of the night, you reach a local team that can respond rather than a recording.
What boiler problems do you fix?
We handle no heat, no hot water, leaks, low pressure, kettling and banging noises, cold radiators, ignition failures, and circulator pump problems, among others. We repair oil, gas, and propane boilers of any brand, no matter who installed the system.
Why is my boiler making banging or kettling noises?
That sound usually comes from sediment and limescale building up on the heat exchanger, which traps water and lets it overheat. It is worth addressing early, since the buildup makes the boiler work harder. A flush or descale often resolves it, and our technician will confirm whether anything more is needed.
My boiler keeps losing pressure. What is wrong?
A boiler that keeps dropping in pressure usually has a leak somewhere in the system or a failing expansion tank. Topping it up over and over only masks the problem, so it is best to have us find and fix the underlying cause before the boiler locks out.
Should I repair or replace my boiler?
We give you an honest assessment. A single repair on an otherwise sound boiler is almost always worth it. If the unit is past 20 to 30 years, has a cracked or leaking heat exchanger, or keeps needing parts, we walk you through a replacement and the rebates a high-efficiency boiler may qualify for.
How much does boiler repair cost?
It depends on the problem, so we give you upfront pricing after the diagnosis rather than a blind quote over the phone. There are no surprises once we start, and service plan members may be eligible for reduced parts and labor costs.
