Boiler Repair in Dunbarton, NH
Voted Manchester, NH Top Plumbing Company
- High Quality
- Customer Service Focused
- 20+ Years Experience
Dunbarton sits up in the hills between Concord and Goffstown, and its quiet country roads hold homes from nearly every era. Around Dunbarton Center, colonial farmhouses and 1800s homes often still heat with steam or gravity hot water through cast iron radiators, which can suffer from worn valves, sediment, and piping that has been added onto over generations. Houses built along Route 13 and the side roads in the 1970s and 1980s mostly use hot water baseboard, where original circulators and zone valves are reaching the end of their lifespan. The newest homes going up on large wooded lots are mostly heated with forced air furnaces instead of boilers.
LHR Plumbing and Heating services all of them. Our boiler repair technicians are just as comfortable with a century-old farmhouse system as a new condensing unit, and you’ll always get an upfront price first.
Boiler Repair & Troubleshooting
Life on higher, wooded ground means Dunbarton winters hit harder, and the weather itself is often what pushes a struggling boiler over the edge.
- Deep cold snaps keep the boiler running nonstop, and that’s when a weak circulator or zone valve gives out and leaves rooms or radiators cold.
- Big temperature swings make old pipes expand and contract, which can lead to banging, knocking, and gurgling as air works through the system.
- Long heating stretches put steady strain on relief valves and expansion tanks, and leaks or pressure problems often follow.
- Storms and power outages can damage igniters and controls, leaving the burner unable to light once the power comes back.
- Windy nights pull heat out of older homes fast, and a boiler with worn controls may short cycle and burn extra fuel trying to keep up.
We fix the real cause instead of covering up the symptom, and every system gets a full test before we leave.
Boiler Repair Prevention & Replacement
Out in Dunbarton, a boiler breakdown in the middle of a snowstorm is the last thing anyone wants, and a yearly tune-up is the best way to avoid one. Before heating season, we clean the burner, test the safety controls, check pressure, and bleed air from the lines. For homes on private wells, we also look for mineral buildup in fill valves and fittings, which can lead to leaks and pressure trouble if it goes unchecked. VIP members get that visit scheduled automatically, along with priority service if something does go wrong in the dead of winter.
Time for a new boiler? If yours is pushing 20 years old, needs a repair every season, or can’t keep an older farmhouse warm on a windy night, replacing it is usually the better investment. A properly sized high-efficiency boiler burns less fuel and delivers steadier heat. When the new system needs gas line work, we handle that too, install everything to current code, and offer financing to help with the cost.
Furnace Repair for Newer Homes
Homes built in Dunbarton in recent years are mostly heated with forced air furnaces, so our furnace repair service matters here as much as boiler work.
- Call us when the furnace runs but the house won’t warm up, which often points to a failing igniter, sensor, or blower.
- Ask us to check a furnace that cycles on and off, since airflow and venting problems are common causes.
- Add heat pumps to share the load with your furnace and cut back on fuel use.
- Let us install and set up a thermostat that matches your furnace and any heat pump.
- Reach out for emergency heating repair when the furnace quits, and we’ll thaw any frozen lines.
For boilers, furnaces, cooling, and plumbing, one trusted number has you covered.
A Recent Boiler Repair in Dunbarton, NH
Paul lives in an older home near Dunbarton Center, and one February morning he noticed his boiler pressure had dropped to almost nothing and the heat had shut off. Our technician found a slow leak at a corroded fitting near the fill valve that had been draining the system for weeks. He replaced the fitting and the valve, refilled the system, and purged the air from every zone. Paul said he was glad to have it fixed before the next storm rolled in.
