Forest Hills Water Heater Repair & Replacement diagnoses gas water heater failures correctly before recommending anything. We are Queens-based water heater specialists — gas water heaters are not one item on a twenty-service menu, they are what we do every day. Written flat-rate price before any work begins. Same-day service throughout Forest Hills and Queens. No after-hours surcharge.
Gas smell near your water heater. Leave the area immediately, do not operate any switches or appliances, open windows if you safely can, call 911 and Con Edison first — then us. A gas smell is a life-safety emergency above all else.
Pilot light that will not stay lit. A pilot that lights then immediately goes out has a thermocouple or thermopile failure — a safety sensor problem, not a gas supply problem. Do not keep attempting to relight. Call us.
No hot water — unit not firing at all. Complete ignition failure on a gas unit has specific diagnosable causes. We identify which before recommending any parts.
Active water leak from the tank. Shut off the cold water supply valve above the unit and call immediately. A leaking tank body cannot be repaired — it needs same-day replacement.
Yellow or orange pilot flame instead of blue. A yellow flame indicates incomplete combustion — a draft, venting, or gas pressure issue that produces carbon monoxide as a byproduct. This is a safety condition requiring immediate attention.
Knowing which component failed determines whether you spend $150 on a thermocouple or $1,800 on a new unit.
Thermocouple failure — most common.
The thermocouple is a safety sensor in the pilot flame. When it fails, the gas valve closes and the pilot will not stay lit. Replacement costs $150 to $250 and is completed the same visit. A technician who recommends full replacement for a thermocouple failure is not diagnosing correctly.
Thermopile failure.
Newer units use a thermopile instead — a larger sensor powering the electronic gas valve. When it fails, the unit will not ignite at all. We test output voltage before replacing it — a thermopile reading within spec means the gas valve is the actual fault.
Gas valve failure.
Controls gas flow to the pilot and main burner. Fails as a stuck solenoid, corroded seat, or failed internal connection — unit will not ignite, fires intermittently, or produces the wrong water temperature. Replacement runs $300 to $550.
Pilot light problems.
Pilot that goes out immediately when you release the button — thermocouple. Pilot that will not light at all — blocked orifice, draft, or Con Edison gas pressure issue. We test supply pressure before replacing components.
Electronic ignition failure.
No burner response, clicking without ignition, or intermittent firing — spark igniter, ignition control board, or gas pressure issue. Each has a different fix. We confirm which before ordering anything.
Draft and venting problems.
Blocked flue, backdrafting vent, or inadequate combustion air causes the thermal cutoff to trip and shut the unit down. If the unit fires then shuts off and the thermocouple tests good, venting is the next diagnostic step.
Sediment buildup.
Gas heats from the bottom. Sediment on the tank floor insulates the metal, causes overheating, and produces the rumbling sound you hear. Caught early — a flush fixes it. Caught late — the tank floor has corroded and replacement is the only option.
T&P valve discharge.
Continuous discharge from the relief valve may be a failed valve or a sign of excess system pressure. We find the root cause before replacing anything — a new valve that keeps discharging has an unresolved underlying problem.
We give you this in writing before any work begins.
Under 8 years old — repair almost always. A gas water heater under eight years old with a single failed component — thermocouple, thermopile, gas valve, T&P valve — has significant remaining service life. Repair is the correct financial decision in almost every case.
8 to 12 years old — honest assessment. We give you repair cost and replacement cost with real numbers. If repair cost exceeds 50% of replacement cost, replacement is usually the smarter long-term decision. If repair cost is significantly below that threshold and the tank shows no signs of internal corrosion, repair is still the right call.
Over 12 years old with a major component failure. Gas valves and heat exchangers on units over 12 years old are expensive repairs on an aging system. We recommend replacement in most cases and tell you exactly why with numbers — not a vague "it's old" dismissal.
Any unit with active tank leakage. A gas water heater leaking from the tank body has corroded internally. No repair is possible. Replacement is the only option and we complete it the same day in most cases.
We publish pricing because you deserve to know what you are looking at before calling anyone.

These are flat-rate ranges. Your specific price depends on the unit brand, part availability, and access. Every job gets a written quote — the exact number, not a range — before we begin.
Gas water heater replacement when repair is not the right call: $1,200 to $2,500 for a standard 40 to 50-gallon unit fully installed, NYC permit included, old unit removed and disposed. Visit our Gas Hot Water Heater Replacement page for more details.
Gas water heaters require proper handling due to the involvement of gas and combustion.
