High-Efficiency Furnace Replacement in Rye, NY - 96% Efficient Two-Stage System Upgrade

Another Rye homeowner is ready for winter thanks to Sustainable Heating & Cooling, where we specialize in high-efficiency gas furnaces built for comfort, safety, and long-term savings. In this project, we replaced an outdated 80% efficient gas furnace with a modern 96% AFUE two-stage system, giving the customer cleaner heat, quieter performance, and lower energy bills.

From 80% to 96% - Why High-Efficiency Gas Furnaces Make a Difference

Standard gas furnaces waste up to 20-40% of the fuel they burn. By upgrading to a 96% efficient condensing furnace, nearly all the heat generated is delivered into the home instead of escaping through the flue. That means better comfort and a noticeable drop in monthly gas costs.

The new two-stage gas furnace is designed for performance and efficiency. It runs on Stage 1 most of the time, using less gas while maintaining steady heat, and automatically switches to Stage 2 only during extreme cold. This provides consistent warmth without the short cycling and high fuel use common with older single-stage models.

Installed to Code - The Right Way, Every Time

At Sustainable Heating & Cooling, every gas furnace installation in Rye is completed 100% to code and held to our own high internal standards.

For this project, we included several critical upgrades:

Condensate Neutralizer - Required by code for all high-efficiency gas furnaces. It safely neutralizes acidic condensate before it drains, protecting plumbing and the environment.

“Fan-in-a-Can” Fresh Air Intake System - This air intake system provides the boiler room with the outside air supply required for safe combustion. It keeps the furnace operating efficiently and improves overall indoor air quality.

Cleaner Air with an Aerus Air Scrubber

To make the home’s air even cleaner, we installed an Aerus Air Scrubber - a professional-grade air purifier that removes allergens, dust, bacteria, and odors from the air. For families with allergies, pets, or asthma, this simple add-on dramatically improves comfort year-round.
