Is it time to replace your furnace?

Most furnaces last 15–20 years. If yours is in that range and any of these sound familiar, replacement usually beats another season of repairs:

  • Heating bills keep climbing even though your usage hasn’t changed — an aging furnace loses efficiency every year.
  • Repairs are getting expensive. Our rule of thumb: if a repair costs more than a third of a new unit and your furnace is 12+ years old, put the money toward replacement.
  • Uneven heat or short cycling — some rooms cold, the system turning on and off constantly.
  • Yellow burner flame, soot, or a CO detector event. Stop using the furnace and call us — this one is a safety issue, not a comfort issue.

What furnace replacement costs in 2026

Real numbers, because that’s what you actually want to know. Typical installed ranges across NYC and Westchester this year:

ProjectTypical 2026 Range (Installed)Timeline

High-efficiency gas furnace (96%+ AFUE)$7,000 – $12,0001–2 days

Furnace repair$90 – $1,200Same day

Where you land in the range depends on your home’s size, ductwork condition, venting, and equipment tier. That’s why we don’t quote over the phone — we measure, then give you an itemized written quote with options at different price points within 24 hours. Permits included; no surprise line items.

Furnace, boiler, or heat pump?

Gas Furnace

The workhorse for homes with existing ductwork. Fastest install, lowest upfront cost, and modern 96%+ AFUE units cut fuel use dramatically compared to a 15-year-old unit.

Boiler

Right for steam and hot-water radiator homes common across the Bronx, Yonkers, and pre-war Westchester housing. We service and replace both gas and oil boilers, including oil-to-gas conversions.

Heat Pump

Heating and cooling in one system. Federal tax credits (up to 30% under the IRA), Con Edison Clean Heat incentives, and NYSERDA programs can take thousands off the price — we handle the paperwork.

Furnace questions we hear every winter

How long does furnace replacement take?

A straightforward gas furnace swap is one day — out in the morning, heating by evening. Boiler work, oil-to-gas conversions, or ductwork repairs add a day or two.

Should I replace my furnace and A/C at the same time?

If both are 12+ years old, yes — combined replacement saves on labor and gets matched, properly sized equipment. If your A/C is under 10 years old, replacing just the furnace is usually the smarter spend.

Do I need a permit for furnace replacement?

Yes, in nearly all of NYC and Westchester. We pull the permits and schedule inspections as part of every install — it’s included in the quote, not an add-on.

What size furnace do I need?

The one matched to your home — not the biggest one. Oversized furnaces short-cycle, wear out faster, and heat unevenly. We size from actual measurements, never square-footage guesswork.

Are there rebates for replacing my furnace or switching to a heat pump?

Yes. High-efficiency equipment qualifies for federal tax credits under the IRA, and heat pumps stack Con Edison Clean Heat and NYSERDA incentives on top. We identify everything you qualify for in the written quote.
