Furnace Installation & Replacement NYC

Whether you need a brand-new furnace installation or a replacement for an aging unit, Fixar provides expert furnace installation across Brooklyn and all five NYC boroughs. We help you select the right furnace type, size, and efficiency rating for your home and budget.

Signs You Need a New Furnace

Your furnace is over 15-20 years old
Frequent repairs — if you are calling for service multiple times per season, replacement is more cost-effective
Rising energy bills despite normal usage
Uneven heating — some rooms are warm while others stay cold
Yellow burner flame instead of blue — indicates incomplete combustion (potential CO risk)
Cracked heat exchanger — a safety hazard that requires immediate replacement
Excessive noise — banging, rattling, or squealing that has worsened over time

Common Furnace Problems We Fix

Ignitor / Ignition Failure

The hot surface ignitor is the most common furnace repair. When it fails, the furnace won't light. We carry replacement ignitors for most brands and can usually fix this in under an hour.

Heat Exchanger Cracks

A cracked heat exchanger is a serious safety issue — it can leak carbon monoxide into your home. We use camera inspection to detect cracks and recommend repair or replacement based on severity and furnace age.

Blower Motor Failure

A failed blower motor means no airflow even though the furnace is firing. Symptoms include no air from vents, overheating shutdowns, or a humming noise. We replace motors and capacitors to restore airflow.

Thermostat Issues

Sometimes the problem is not the furnace at all — a malfunctioning thermostat or bad wiring can prevent the furnace from receiving the call for heat. We diagnose and resolve control issues.

Flame Sensor Problems

A dirty or failing flame sensor causes the furnace to light briefly then shut off. Cleaning or replacing the flame sensor is a quick, affordable repair that restores reliable operation.

Draft Inducer Motor

The draft inducer creates proper venting before the burners ignite. When it fails, the furnace locks out for safety. We replace inducer motors and verify proper flue draft.

Furnace Maintenance & Tune-Up

An annual furnace tune-up prevents breakdowns, improves efficiency, extends equipment life, and — most importantly — keeps your family safe from carbon monoxide risks. Schedule your tune-up before heating season begins.

Our Furnace Maintenance Checklist

Inspect and clean the burners — ensure proper flame pattern and clean combustion
Test the ignitor and flame sensor — clean or replace if worn
Check the heat exchanger — inspect for cracks, corrosion, or carbon buildup
Combustion analysis — verify gas pressure, CO levels in flue, and overall combustion efficiency
Replace the air filter — a clogged filter restricts airflow and forces the furnace to work harder
Lubricate blower motor and bearings — reduces wear and prevents overheating
Check thermostat calibration — ensure accurate temperature readings and proper cycling
Inspect the flue and venting — verify no blockages and proper draft
Test all safety controls — high-limit switch, pressure switch, and rollout switches
Check electrical connections — tighten terminals, test capacitors, and inspect wiring
Test CO detectors — we verify your carbon monoxide detectors are working and properly placed

Schedule your annual furnace tune-up for September or October — before the heating season rush. Ask about our maintenance plans for priority scheduling and discounted service.

Furnace Types by Fuel Source

Gas Furnaces

The most common type in NYC. Runs on natural gas from Con Edison or National Grid. Available in 80% AFUE (standard) and 90-98% AFUE (high-efficiency condensing) models. Gas furnaces heat quickly and have low operating costs relative to electric.

Electric Furnaces

Use electric heating elements instead of a burner. No combustion means no CO risk and no venting required. Higher operating costs than gas in most of NYC, but a good option for buildings without gas service. Simple design with fewer components to fail.

Oil Furnaces

Still found in some older Brooklyn and Queens homes. Require a fuel oil storage tank and regular oil deliveries. Generally less efficient than modern gas furnaces. Fixar can maintain your oil furnace or help you convert to gas or electric.

Propane Furnaces

Used in areas without natural gas infrastructure. Less common in NYC but found in some Long Island homes. Works similarly to a gas furnace but uses propane delivered to an on-site tank.

Furnace Safety — Carbon Monoxide & Fire Prevention

Gas and oil furnaces produce combustion byproducts including carbon monoxide (CO) — an odorless, colorless gas that can be lethal. Furnace safety is not something to take lightly, especially in tightly sealed NYC apartments and homes.

Carbon Monoxide Warning Signs

Yellow or flickering burner flame (healthy flame is steady and blue)
Soot or black marks around the furnace or on walls near vents
Excessive moisture on windows or walls near the furnace
Stale or stuffy air and a noticeable lack of fresh air
Family members experiencing headaches, nausea, or dizziness — evacuate immediately and call 911

Furnace Safety Best Practices

Install CO detectors on every floor and near sleeping areas — required by NYC Local Law 7
Never block furnace vents or air intakes
Keep the area around your furnace clear — no storage, no flammable materials within 3 feet
Change your air filter regularly — a clogged filter causes overheating
Schedule annual professional maintenance — a technician can detect cracked heat exchangers, blocked flues, and gas leaks before they become dangerous
Know your shutoff — learn how to turn off the gas supply to your furnace in an emergency

Cracked Heat Exchanger — The Most Dangerous Furnace Problem

The heat exchanger separates combustion gases from the air circulating through your home. When it cracks, carbon monoxide can leak into your living space. A cracked heat exchanger cannot be safely repaired — the furnace must be replaced. This is one of the most important reasons to schedule annual furnace maintenance: early detection can save lives.

Furnace Repair vs. Replace — How to Decide

Not sure whether to repair your current furnace or invest in a new one? Here is a practical guide:

Repair Your Furnace If...

It is less than 12 years old
The repair cost is less than 50% of a new furnace
This is the first or second repair in recent years
The heat exchanger is intact and not cracked
The furnace still heats your home evenly and reliably

Replace Your Furnace If...

It is over 15-20 years old
You are spending $500+ per year on repairs
The heat exchanger is cracked (replacement is mandatory)
Your energy bills are steadily increasing
It is an 80% AFUE model and you want to upgrade to 95%+ efficiency
You are experiencing uneven heating, strange odors, or excessive noise

Fixar provides honest, straightforward recommendations. We will never push a replacement when a repair is the better option. Schedule a diagnostic and we will give you both options with clear pricing.

Frequently Asked Questions

How long does a furnace last?

A well-maintained gas furnace typically lasts 15-25 years. Electric furnaces can last 20-30 years since they have fewer mechanical components. The heat exchanger is usually the component that determines end of life.

How often should I change my furnace filter?

Standard 1-inch filters should be changed every 1-3 months during heating season. High-efficiency 4-inch or 5-inch media filters last 6-12 months. In NYC, dust and air quality levels mean filters may need more frequent replacement. A dirty filter is the number one cause of preventable furnace problems.

Why does my furnace keep turning on and off?

Short cycling is commonly caused by a dirty air filter restricting airflow, a malfunctioning thermostat, an overheating furnace (tripping the high-limit switch), or a faulty flame sensor. Start by checking your filter — if it is clogged, replace it. If the problem persists, call for a diagnostic.

Is a furnace tune-up worth it?

Absolutely. A $150-$300 annual tune-up can prevent $500-$2,000+ emergency repairs, improve efficiency by 5-15%, and — most critically — detect carbon monoxide risks from cracked heat exchangers or blocked flues. It is the single best investment you can make in your furnace.

What AFUE rating should I look for?

AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel to heat. For NYC, we recommend 90% AFUE or higher. High-efficiency models (95-98% AFUE) cost more upfront but save $200-$500 per year on gas bills and qualify for utility rebates.

Do I need a permit to replace a furnace in NYC?

Yes. The NYC Department of Buildings requires permits for furnace installations and replacements. Gas piping work also requires separate permits. Fixar handles all permit applications, inspections, and code compliance as part of every installation.

Can you convert my oil furnace to gas?

Yes. Fixar handles complete oil-to-gas furnace conversions including new gas furnace installation, gas line connection, Con Edison or National Grid coordination, old oil tank removal, and all NYC permits. Most conversions are completed in 1-2 days.
