Boiler Repair in Huntington Station, NY

Air bleeders, or automatic air vents, let trapped air escape from a hot-water system. Over time the internal float sticks or the valve starts to drip. Air bleeder work was the most common boiler repair in our Huntington Station records. A failed vent lets air collect, causing gurgling pipes and cold radiators at the top of the system.

In two-story homes and converted multi-family buildings, air gathers on the upper floor first. We replace the vent, purge air from each zone, and check the fill valve and system pressure, since a system running at low pressure draws air in more easily.

The aquastat watches boiler water temperature. It fires the burner when the water cools and shuts it off when the water reaches its high limit. The relay inside switches the burner and circulator. When it sticks or burns out, the boiler may not fire at all, or the circulator may never start, leaving radiators cold.

One of our Huntington Station visits was an aquastat relay replacement. We test the sensor and settings first, since a bad setting can mimic a failed relay. On oil boilers with a tankless coil, the aquastat also keeps domestic hot water ready, so a failure can mean no heat and no hot water together.

Old basement piping sags as hangers rust or work loose, and heavy cast-iron and copper lines put stress on joints and on the boiler's own connections. On one Huntington Station visit we installed new brackets to support the boiler piping. Proper support stops vibration noise and keeps fittings from cracking or seeping.

Look for drooping pipes near the boiler, stained joints or water spots on the floor. Banging or ticking when the heat starts can also point to piping that shifts as it warms and expands.

We check the thermostat call, power to the boiler, the burner and its safety controls, and the pressure gauge. Then we look at circulators and zone valves to see whether hot water is actually leaving the boiler. Each step narrows the cause, whether it is the burner, the controls or the movement of water.

If the gauge reads too high or too low, see our boiler pressure guide. For an oil boiler that has locked out, read the reset button guide before pressing it more than once. If one baseboard loop stays cold, the baseboard heat guide helps.

Yes. A yearly tune-up cleans the burner, checks combustion, tests the aquastat and relief valve, and finds air and pressure issues before they turn into a no-heat call. One Huntington Station home in our records is on a service agreement that covers heating and cooling maintenance together.

Oil boilers benefit most, since soot builds up quickly. See how a pre-season visit goes in our Huntington Station oil boiler tune-up, and compare options on our maintenance page.
