Boiler Installation & Replacement NYC
Whether you are replacing an aging boiler or installing a new system in a renovation, Fixar provides expert boiler installation across Brooklyn and all five NYC boroughs. We size, select, and install the right boiler for your building and budget.
When to Replace Your Boiler
- Your boiler is over 15-20 years old and efficiency has declined
- Frequent breakdowns and repair costs exceeding $1,500/year
- Uneven heating throughout your home or building
- Rising gas or oil bills despite no change in usage
- Visible corrosion, rust, or water pooling around the unit
- Your current boiler has been flagged during a NYC DOB inspection
Our Installation Process
Assessment & Sizing
We evaluate your building's heating load, existing piping, fuel source, and venting to recommend the right boiler type and size.
Proposal & Permits
You receive a written estimate with equipment specs, timeline, and total cost. We pull all required NYC DOB permits and schedule inspections.
Removal & Installation
We safely disconnect and remove your old boiler, install the new unit, connect piping, venting, and fuel lines, and perform a complete system flush.
Testing & Commissioning
We fire the boiler, test all zones, check for leaks, verify safety controls, and walk you through operation and maintenance.
Oil-to-Gas Conversion
NYC is phasing out heavy fuel oils. If your building still runs on #4 or #6 oil, now is the time to convert to natural gas or a cleaner alternative. Fixar handles the full conversion process including Con Edison gas service coordination, new gas piping, boiler replacement, and DEP permits. Converting to gas can reduce your heating costs by 20-40% and eliminate oil delivery hassles.
Boiler Repair Brooklyn & NYC
A boiler breakdown in a NYC winter is more than an inconvenience — it is a health and safety hazard. Fixar provides fast, reliable boiler repair across all five boroughs with same-day and emergency service available.
Common Boiler Problems We Repair
No Heat or Hot Water
Can be caused by a failed thermostat, broken circulator pump, faulty zone valve, low water pressure, or a tripped safety switch. We diagnose systematically and fix the root cause.
Boiler Leaking Water
Leaks may come from corroded pipes, a failed pressure relief valve, a cracked heat exchanger, or loose fittings. We locate and repair leaks before they cause water damage.
Kettling (Banging Noises)
Limescale buildup or sludge restricts water flow through the heat exchanger, causing the water to boil and create banging sounds. We flush and descale the system.
Pilot Light or Ignition Failure
Thermocouple failure, clogged pilot orifice, or a faulty ignition module can prevent the boiler from firing. We replace worn ignition components and restore operation.
Radiators Not Heating Evenly
Air trapped in the system, a failing circulator pump, or stuck zone valves can cause cold spots. We bleed radiators, replace pumps, and balance your heating system.
Pressure Problems
Low boiler pressure causes inadequate heating; high pressure triggers safety relief valves. We check the expansion tank, fill valves, and pressure reducing valve to restore proper operation.
Boiler Maintenance Schedule
Annual boiler maintenance is not optional in NYC — it is required by law for many buildings and is the best way to prevent mid-winter breakdowns. A well-maintained boiler runs safer, lasts longer, and costs less to operate.
What Our Annual Boiler Tune-Up Includes
- Combustion analysis — we test flue gas to verify the boiler is burning fuel cleanly and efficiently
- Heat exchanger inspection — checked for cracks, corrosion, and carbon buildup that reduce heat transfer
- Burner cleaning and adjustment — ensures proper flame pattern and fuel-air ratio
- Safety controls testing — we test the pressure relief valve, low-water cutoff, high-limit control, and gas valve
- Water chemistry check — test pH levels and add treatment chemicals if needed to prevent corrosion
- Circulator pump inspection — check for leaks, noise, and proper flow rates
- Expansion tank check — verify proper air charge to prevent pressure fluctuations
- Flue and venting inspection — check for blockages, corrosion, and proper draft
- System flush — recommended every 3-5 years to remove sludge and scale buildup
Best time to schedule: Late summer or early fall, before heating season begins. Ask about our maintenance plans for priority scheduling and discounted rates.
Boiler Types We Service
Fixar works with every type of residential and light commercial boiler found in NYC buildings. Here are the main types we install, repair, and maintain:
Gas Boilers
The most common type in NYC. Runs on natural gas supplied by Con Edison or National Grid. Available in standard and high-efficiency condensing models. We service all major brands.
Oil Boilers
Still found in many older Brooklyn brownstones and multi-family buildings. We service, repair, and can convert oil boilers to cleaner natural gas.
Combi Boilers
Provide both space heating and domestic hot water from a single compact unit — no separate water heater needed. Ideal for small NYC apartments where space is at a premium.
System Boilers
Work with a separate hot water storage cylinder. Good for homes with multiple bathrooms that need high hot water demand. Common in larger Brooklyn homes and townhouses.
Condensing Boilers
Capture heat from exhaust gases that standard boilers waste, achieving efficiency ratings of 90-98%. Required for new installations in NYC and eligible for utility rebates.
Electric Boilers
Zero-combustion heating for buildings without gas service. Smaller footprint, no flue required, and no risk of carbon monoxide. Increasingly popular in new construction.
Emergency Boiler Repair — 24/7
A boiler failure during a NYC winter is dangerous. Pipes can freeze and burst within hours. Vulnerable residents — children, elderly, and those with medical conditions — are at immediate risk. Fixar provides 24/7 emergency boiler repair with an average response time of under 2 hours.
When to Call for Emergency Boiler Service
- Complete loss of heat when outdoor temperatures are below freezing
- Gas smell near the boiler — leave the building immediately and call 911 first, then call us
- Water flooding from a burst pipe or failed boiler
- Carbon monoxide alarm sounding — evacuate first, then call
- No hot water in a building with a combi boiler (your only hot water source)
- Boiler making loud banging or whistling noises and won't shut off
Emergency boiler repair: (929) 351-5179 — available 24 hours a day, 7 days a week, 365 days a year.
NYC Boiler Inspection Requirements
New York City has strict boiler regulations enforced by the Department of Buildings (DOB). Property owners are legally responsible for compliance.
Annual Boiler Inspection
All boilers in NYC buildings (other than one- and two-family homes with boilers under 350,000 BTU input) must be inspected annually by a licensed boiler inspector and the report filed with the DOB. Failure to comply results in fines starting at $1,000 per violation.
Key NYC Boiler Regulations
- DOB permits required for all new boiler installations and major repairs
- Annual inspection filing due each year — Fixar can coordinate your inspection
- Local Law 87 — buildings over 50,000 sq ft must undergo energy audits including boiler efficiency testing
- Local Law 43 (oil phase-out) — #4 and #6 fuel oil boilers must be converted to cleaner fuels
- CO detector requirements — NYC Local Law 7 requires carbon monoxide detectors near all fuel-burning appliances
- DEP air permits — required for boilers above certain BTU thresholds
Fixar helps property owners and building managers stay compliant with all NYC boiler regulations. We can coordinate annual inspections, file required DOB paperwork, and ensure your boiler meets current code.

Frequently Asked Questions
How long does a boiler last?
A well-maintained gas or oil boiler typically lasts 15-25 years. Condensing boilers may have a slightly shorter lifespan of 12-20 years due to the acidic condensate. Annual maintenance is the biggest factor in boiler longevity.
What should I do if I smell gas near my boiler?
Leave the building immediately. Do not turn on or off any lights or electrical switches. Call 911 and Con Edison's gas emergency line (1-800-752-6633) from outside. Once the gas company has cleared the area, call Fixar for boiler inspection and repair.
How often does my boiler need maintenance?
At minimum, once per year before heating season (ideally in September or October). Buildings with older boilers or high usage should consider twice-yearly service. NYC requires annual inspections for most commercial and multi-family boilers.
Should I repair or replace my boiler?
As a general rule: if your boiler is under 12 years old and the repair costs less than 50% of a new boiler, repair it. If it is over 15 years old, needs frequent repairs, or has a cracked heat exchanger, replacement is usually the smarter investment. Fixar provides honest recommendations — we never push unnecessary replacements.
Can you convert my oil boiler to gas?
Yes. Fixar handles the complete oil-to-gas conversion process including new gas boiler installation, gas piping, Con Edison coordination, oil tank decommissioning, and all NYC permits. Most conversions are completed in 2-4 days.
Do I need a permit to replace my boiler in NYC?
Yes. The NYC Department of Buildings requires a permit for all boiler installations and replacements. Fixar pulls the permit, coordinates the DOB inspection, and ensures your installation meets all NYC mechanical and plumbing codes.
What is a condensing boiler and is it worth it?
A condensing boiler recovers heat from exhaust gases that a standard boiler vents out. This makes them 90-98% efficient compared to 80-85% for non-condensing models. In NYC, condensing boilers are now required for most new installations. The higher upfront cost is typically recouped in 3-5 years through lower gas bills.
