Durastar offers a straightforward, value-focused furnace line for residential heating. Its gas furnaces are available in 80% and 95% single-stage and 96% two-stage models for up-flow and horizontal installs.
Durastar furnace highlights:
Here is roughly what a new furnace costs to install, using current national averages. Durastar offers both standard and high-efficiency models, so a Durastar install can land anywhere in the ranges below depending on the model you choose.
| Furnace type | Typical installed cost (U.S. average) |
|---|---|
| Standard-efficiency (80-83% AFUE) | $3,800 - $6,000 |
| High-efficiency (90-98% AFUE) | $6,000 - $10,000 |
National averages from HomeAdvisor and Angi (2026): gas furnace installation runs about $3,800 to $10,000 (up to $12,000 for premium modulating units), and the furnace itself is 50-75% of the project. Your Long Island price depends on size, efficiency, ductwork and venting.

Every Durastar furnace installation starts with a free in-home assessment and a proper heat-loss (Manual J) calculation, so your furnace is sized right and your ducts can handle it. Our licensed, factory-trained technicians set up an 80% AFUE model out the chimney, or a 90%+ condensing model out a sidewall with a condensate drain, pull permits, connect the thermostat, and fully commission the system before we leave.
We will walk you through single-stage, two-stage and (where offered) modulating Durastar options, plus variable-speed ECM blowers for quieter, more even heat. See our full furnace service or browse all furnace brands.
If your Durastar furnace is short cycling, blowing cold air, making noise or not running, our technicians diagnose and repair it quickly, with 24/7 emergency no-heat service across Suffolk and Nassau County. We carry or quickly source common Durastar parts, so most repairs are finished in a single visit.
Our annual tune-up cleans the burners, inspects the heat exchanger for cracks (a carbon-monoxide safety check), tests the safety controls and blower, and replaces the filter, keeping your furnace safe and efficient and helping keep the warranty valid.
When a furnace is beyond economical repair, or a cracked heat exchanger makes it unsafe, we make replacement simple. We will tell you honestly whether your Durastar furnace is worth fixing or whether a newer, high-efficiency unit will pay for itself in lower bills.
Many Long Island homeowners use a replacement to move up to a 90-98% AFUE furnace with a two-stage or modulating burner and a variable-speed ECM blower for even, quiet comfort. We handle removal and disposal, any venting or duct changes, and available rebates and financing, all with a free estimate up front.
Catching these early usually means a smaller, cheaper fix. Call us if your Durastar furnace shows any of the following:
