Why is my heating system not producing enough heat?

Insufficient heat usually comes from a boiler that's short-cycling, a failing circulator pump, air in the lines, sludged radiators, or a system that's undersized for the space. We diagnose the cause and restore full output.

Why isn't my heating system starting?

A heating system that won't fire may have a tripped safety switch, a faulty igniter, no fuel supply, a bad thermostat, or a locked-out burner control. We troubleshoot the control sequence and get it running safely.

Can older steam or hydronic systems be repaired?

Yes. Older steam and hydronic systems are very repairable. We service steam traps and vents, replace circulators and zone valves, and re-balance distribution — often restoring comfort without a full replacement.

Do you repair heating controls and thermostats?

We do. Thermostat and heating-control problems are a common cause of no-heat or short-cycling. We test and replace thermostats, aquastats, and zone controls as part of a complete diagnostic.

Common Heating Problems We Repair

Heating problems in New York buildings usually trace to a few common causes. Our technicians diagnose the real issue and repair it — not just the symptom:

No heat

A heating system that runs but produces no heat often has a faulty circulator, a stuck zone valve, air in the lines, or a tripped limit. We find and fix the cause.

Insufficient heat

If your system can't keep up, it may be short-cycling, undersized, or suffering from sludged radiators and a failing pump. We restore full output.

Uneven heating

Cold spots and hot rooms usually mean air in the pipes, a stuck zone valve, unbalanced steam vents, or a failing circulator. We balance the system.

Heating system not starting

A system that won't fire may have a tripped safety switch, a faulty igniter, no fuel, a bad thermostat, or a locked-out burner control. We troubleshoot safely.

Unusual heating-system noises

Banging, gurgling, or humming points to air in the lines, a failing pump, or water hammer in steam pipes. We vent, re-pressurize, and quiet the system.

Thermostat & heating control issues

Short-cycling, no response, or wrong temperatures often trace to a failing thermostat, aquastat, or zone control. We test and replace heating controls.

Our Heating Repair Process

1
Understand the symptoms
We listen to what you're experiencing — no heat, uneven heat, noise — and inspect the boiler, distribution, and controls.
2
Diagnose the distribution & controls
We test circulators, zone valves, steam vents, thermostats, and aquastats to pinpoint the failure in the heating system.
3
Clear repair recommendation
You get a straightforward explanation of the problem and your repair options before any work begins.
4
Repair, test & verify comfort
We complete the repair, fire up the system, and confirm even heat reaches every room before we leave.

Steam Heating Repair & Hydronic Heating Repair

Steam heating repair

We repair banging pipes, faulty steam traps and vents, water feeder issues, and uneven steam distribution in older NYC buildings. See our steam heating service for details.

Hydronic heating repair

We repair circulator pumps, zone valves, expansion tanks, and air-bound hydronic loops that leave rooms cold. See our hydronic heating page, or our boiler repair service.

When Repair May Not Be Enough

Most heating problems can be repaired. But if your system is aging, inefficient, or repeatedly breaking down, a replacement may cost less over time. Replacement often makes sense when:

Your heating system is over 15–20 years old.
Repairs are becoming frequent and costly.
Energy bills keep rising despite normal usage.
