Boiler & FurnaceRepair Services
Reliable boiler and furnace repair for residential and commercial systems — focused on safety, diagnostics, and dependable heat across NYC and the Tri-State area.
Common Boiler Problems
- Boiler not producing heat
Could be a failed circulator pump, bad zone valve, faulty aquastat, or airlock in the system. We diagnose the root cause and restore heat quickly.
- Uneven or inconsistent heating
Often caused by air trapped in radiators, a failing zone valve, or imbalanced water flow. We balance the system and verify each zone responds correctly.
- Unusual noises or vibration
Banging, kettling, or gurgling sounds typically indicate mineral buildup, air in the lines, or a failing pump bearing. We identify and resolve the noise source.
- Pressure loss or frequent shutdowns
Usually traced to a leaking expansion tank, faulty pressure-relief valve, or a small system leak. We pressure-test the system and replace failed components.
- Leaks or corrosion
Pinhole leaks, corroded fittings, and weeping valves can cause water damage and efficiency loss. We locate the leak, assess pipe condition, and make reliable repairs.
Common Furnace Problems
- Furnace not turning on
Often caused by a faulty igniter, tripped safety switch, or a malfunctioning control board. We test each component in sequence to isolate and resolve the failure.
- Weak or uneven heat output
Clogged filters, failing blower motors, or partially blocked ductwork can starve rooms of heat. We measure airflow and temperature rise to find the restriction.
- Frequent cycling or shutdowns
Short cycling usually points to an overheating heat exchanger, a dirty flame sensor, or incorrect thermostat wiring. We diagnose the root cause so the fix lasts.
- Unusual noises or vibrations
Banging, squealing, or rattling can signal loose blower wheels, worn bearings, or expanding ductwork. We inspect mechanical components and secure or replace worn parts.
- Blower or ignition issues
A blower that won't start or an igniter that fails to glow prevents the entire heating cycle. We test capacitors, motors, and ignition assemblies to restore operation.
Our Approach
Whether it's a boiler or furnace, we take an engineering-led approach — verifying controls, pressure behavior, airflow, and system response before recommending any repair. Our focus is resolving the cause, not masking symptoms.
- Control & safety checks — every limit switch, aquastat, pressure switch, and safety control verified before we proceed
- Combustion analysis — measuring flue gas temperatures and CO levels to ensure a clean, efficient burn and safe venting
- Circulation & airflow assessment — testing pump operation, blower performance, static pressure, and temperature rise
- Heat delivery verification — confirming each zone reaches target temperature evenly and consistently
- Written findings — a clear summary of what we found, what we fixed, and what to watch going forward
Questions & Answers
Common questions about our boiler and furnace repair services.
Do you install new boilers or furnaces?
Our focus is on repair, diagnostics, and maintenance rather than full installations. This specialization allows us to invest deeply in understanding existing systems, extending their lifespan, and keeping them running safely.
What types of boilers do you service?
We service gas-fired, oil-fired, steam, and hot-water boiler systems across residential and commercial properties — from single wall-hung combi boilers to multi-boiler plants and cast-iron sectional systems.
What furnace types do you service?
We service single-stage, two-stage, and modulating gas furnaces, along with oil-fired and electric models. Our technicians carry diagnostic equipment compatible with major brands like Carrier, Lennox, Trane, Rheem, Goodman, and Bryant.
Do you service older systems?
Absolutely. NYC is full of pre-war buildings with cast-iron steam boilers and legacy furnaces. We have extensive experience with older systems, hard-to-find parts, and discontinued control boards.
Can you diagnose safety issues?
Yes. Every service call includes gas-leak detection, carbon monoxide screening, pressure-relief or heat-exchanger inspection, and verification that all safety controls shut the system down when they should.
Will I receive an estimate first?
Yes. After our initial diagnostic visit, we provide a clear written estimate before any repair work begins. You approve the scope of work before we proceed — no surprises.
How often should my system be serviced?
We recommend having your boiler or furnace professionally serviced at least once a year, ideally before the heating season begins in early fall. Annual maintenance catches small problems before they become expensive failures.
What are signs my system needs repair?
Common warning signs include unusual noises, uneven heating, frequent shutdowns, visible leaks or corrosion, a yellow pilot flame, and higher-than-normal energy bills. If you notice any of these, schedule a diagnostic visit.
