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

Concord’s housing tells the story of a capital city that grew outward over two centuries. The South End and North End are lined with Victorians and older multi-family homes, and many still run steam heat through cast iron radiators that suffer from leaky valves, clogged vents, and low water problems. The Heights and parts of West Concord filled in after World War II with ranches and capes heated by hot water baseboard, where pumps and zone valves have been working for decades. New construction on the city’s outskirts is a different story, since most recently built homes use forced air furnaces rather than boilers.
LHR Plumbing and Heating works on all of it. Whether you own a century-old steam system a few blocks from Main Street or a brand-new condensing unit, our boiler repair technicians find the problem, explain your options, and give you an upfront price.
Boiler Repair & Troubleshooting
Concord gets some of the coldest winter nights in southern New Hampshire, and each neighborhood’s boilers tend to break down in their own way when the temperature drops.
- In South End and North End homes, cold radiators on the upper floors often trace back to clogged air vents or a steam boiler running low on water.
- Older steam and hot water systems across the city bang or gurgle when trapped air or pooled water sits in the pipes.
- Mid-century homes in the Heights can show leaks or swinging pressure readings as original expansion tanks and relief valves wear out.
- High-efficiency boilers may refuse to ignite or lock out with an error code when a sensor or igniter fails on a frigid morning.
- Any boiler that short cycles will push fuel bills higher, especially one that was oversized for the house.
Whatever is behind it, we repair the cause instead of patching the symptom, then test the system from top to bottom before we head out.
Boiler Repair Prevention & Replacement
Most of the no-heat calls we get in January start as small problems a tune-up would have caught. On older Concord steam systems, that means checking the low water cutoff, cleaning the sight glass, and flushing out sediment. On hot water and high-efficiency boilers, it means testing circulators, safety controls, and venting. VIP members get this visit booked every year before heating season, plus priority repair service if anything fails later.
Time for a new boiler? When repairs keep piling up, the boiler is two decades old, or it can’t keep up with a drafty older house, replacing it usually saves money over time. A high-efficiency boiler paired with modern thermostats gives you steadier heat and far better control than the old dial on the wall. We install to current code and offer financing so a new system doesn’t strain your budget.
Furnace Repair for Newer Homes
While Concord’s older neighborhoods run on boilers, new homes on the outskirts of the city are almost always built with forced air furnaces. Our furnace repair service covers them just as thoroughly.
- If your furnace won’t start, we check the igniter, flame sensor, and control board to find the failure.
- If it blows cold air or cycles on and off, we look at the filter, airflow, and venting.
- If you’d like extra efficiency, we install and service heat pumps that team up with your furnace.
- If your thermostat isn’t talking to the system correctly, we reset or replace it.
- If the furnace dies on a bitter night, our emergency heating repair responds, and we can thaw any frozen lines.
For boilers, furnaces, cooling, and plumbing, one trusted number does it all.
A Recent Boiler Repair in Concord, NH
When the radiators on the third floor of Dave’s South End Victorian went cold last December, he figured his old steam boiler was finished. Our technician found a clogged sight glass and a failed low water cutoff that kept shutting the burner down before steam could reach the top of the house. He replaced the cutoff, cleaned the glass, and swapped out two stuck radiator vents upstairs. Dave said the third floor was warm by evening, and he was glad he didn’t have to replace a boiler that still had years left in it.
