An Energy-Efficient Heating and Cooling Upgrade for a Westchester County Home

At Sustainable Heating & Cooling, we recently completed a gas furnace installation as part of a hybrid heating and cooling system upgrade for a homeowner in Mamaroneck, NY. This project is a great example of how we help homeowners maximize comfort while improving energy efficiency, especially during Westchester’s cold winters.

If you're in Mamaroneck and looking to upgrade your heating system, combining a high-efficiency gas furnace with a cold-climate heat pump offers both comfort and cost savings throughout the year.

Project Overview: Hybrid Gas Furnace and Heat Pump Installation

The homeowner reached out to us looking for a more reliable and energy-conscious way to heat and cool their home. Their old furnace was outdated and no longer keeping up with demand. After evaluating the home’s size and layout, we recommended a hybrid system that pairs a new gas furnace with an electric heat pump. This dual-fuel setup ensures efficient performance year-round.

The primary service we performed was a gas furnace installation, sized and selected to handle the home’s heating needs during extremely cold temperatures. The new system also includes a variable-speed heat pump to provide efficient electric heating during mild weather and cooling during the summer.

Why a Hybrid System Made Sense in Mamaroneck, NY

Mamaroneck’s climate includes hot summers and freezing winters. A hybrid heating and cooling system adapts to these seasonal swings automatically. When temperatures are above 40°F, the heat pump handles heating duties at a lower cost. When the temperature drops, the gas furnace takes over to deliver strong, consistent heat.

This setup gives the homeowner:

- Lower energy bills

- Smart fuel switching based on outdoor conditions

- Comfortable temperatures year-round

- Reduced greenhouse gas emissions

What the Homeowner Gained from Their New Gas Furnace Installation

- High-efficiency gas furnace installation for reliable winter heating

- Cold-climate heat pump for efficient mild-weather heating and summer cooling

- Smart thermostat that automatically chooses the most efficient heat source

- Clean, quiet comfort with variable-speed technology

- Reduced fuel usage and better long-term savings

This hybrid system delivers maximum energy efficiency, while ensuring the home stays warm even on the coldest days in Mamaroneck.
