Boiler Repair in Derry, NH
Voted Manchester, NH Top Plumbing Company

- 20+ Years Experience
Derry grew in waves, and each wave left behind a different kind of boiler. The oldest homes along Broadway downtown and in the historic East Derry village date back to the 1800s, and many still heat with steam or hot water radiators that deal with sticky valves, sediment, and tired piping. The biggest boom came in the 1970s and 1980s, when raised ranches, split-levels, and capes filled neighborhoods across town, almost all with hot water baseboard and boilers that are now well past their prime. Newer subdivisions and condos built since then mostly went with forced air furnaces, so boilers in Derry are largely found in the town’s older and boom-era homes.
Whichever wave your home came from, LHR Plumbing and Heating can get it warm again. Our boiler repair technicians know old radiator systems and new condensing units equally well, and we always share the price upfront.
Boiler Repair & Troubleshooting
Derry’s split-level and raised ranch homes ask a lot of a boiler, which has to push heat up from the basement through long baseboard loops all winter long.
- Calls about cold baseboard on the upper floor usually turn up a seized circulator, a failed zone valve, or a loop full of air.
- Calls about banging or gurgling pipes usually lead us to trapped air or old piping that has sagged over the years.
- Calls about water near the boiler usually point to a worn relief valve, a waterlogged expansion tank, or pressure that has crept too high.
- Calls about a boiler that won’t fire usually come down to a bad igniter, a dirty flame sensor, or a failed control.
- Calls about high fuel bills often reveal a boiler that short cycles all day without ever heating the house properly.
Whatever the call, we fix the source of the problem instead of the symptom, then test the system from end to end before we leave.
Boiler Repair Prevention & Replacement
In a lot of Derry homes, the boiler is tucked into a tight utility room behind a finished basement, which makes it easy to forget about until it stops. A tune-up before heating season keeps it from getting to that point. We clean the burner, check pressure and safety controls, bleed the lines, and swap out worn parts before they cause a mid-winter breakdown. Our membership plans schedule that visit for you every year and give you priority service if a repair comes up later.
Time for a new boiler? Many of the boilers installed during Derry’s 1970s and 1980s building boom are reaching the end of the road around the same time. If yours needs repairs every winter, runs constantly, or leaves the upstairs chilly, replacement usually pays off. A high-efficiency boiler paired with modern thermostats gives you even heat on every level, and we install everything to current code with financing available.
Furnace Repair for Newer Homes
New subdivisions and condos in Derry are mostly built with forced air furnaces, and our furnace repair team takes care of them just like the boilers in town’s older homes.
- For furnaces that won’t fire, we replace worn igniters, clean flame sensors, and repair control boards.
- For weak airflow or uneven heat between floors, we fix blower motors and check duct connections at the unit.
- For better efficiency, we install heat pumps that share the load with your furnace.
- For newer smart thermostats, we handle setup and troubleshooting.
- For no-heat nights, our emergency heating repair responds, and we thaw frozen lines if the cold reaches your pipes.
Boiler or furnace, one trusted number covers your heating, cooling, and plumbing.
A Recent Boiler Repair in Derry, NH
Lisa called us last winter from her raised ranch in East Derry because the downstairs family room was toasty while the bedrooms upstairs barely got warm. Our technician found that the motor on the upstairs zone valve had burned out, so hot water never made it to that loop. He replaced the motor, purged the air from the line, and watched both zones heat evenly before packing up. Lisa said her kids finally stopped dragging their blankets downstairs to sleep on the couch.

Frequently Asked Questions
Sometimes, yes. Many older cast iron boilers are built tough, and a repair can buy a few more good years. If it’s leaking, rusting at the base, or breaking down every winter, we’ll tell you honestly when replacement makes more sense.
Banging, squealing, or rattling usually points to a blower motor, a loose panel, or an ignition issue. It’s best to have it checked early before a small repair turns into a breakdown.
In most cases, yes. Boiler replacements typically require a permit and inspection through the Town of Derry, and our team handles that for you.
Pipes in garages, crawl spaces, and along outside walls tend to freeze first. Shut off the water if a pipe has burst, then call us for frozen line repair so we can thaw the lines and get your boiler running again.
Yes. We provide emergency heating service throughout Derry and work to get a technician to your door quickly. Call us as soon as your boiler stops working.
