About Home Efficiency Experts

Making Long Island Homes Healthier, Happier, and More Efficient — One Family at a Time

At Home Efficiency Experts, we’re more than a team of building science professionals—we’re a family, and we respectfully treat your home like it’s our own. Based right here on Long Island, our company has been helping local homeowners stay warm in the winter, cool in the summer, and comfortable all year long with energy-saving upgrades that truly make a difference.

We start with a free energy assessment, where our trained experts pinpoint the areas your home is losing energy—whether that’s from poor insulation, leaky ducts, outdated heating or cooling systems, or lack of air sealing. Then, we walk you through practical, personalized solutions that reduce your energy bills and improve your home’s comfort and indoor air quality.

Whether you’re looking to install a cold climate ductless mini split heat pump, upgrade your insulation, or explore rebates for air source heat pump systems in New York, our team will guide you every step of the way. We specialize in energy-efficient HVAC upgrades, and we know how to make them affordable, often using rebates from NYSERDA and PSEG Long Island to significantly lower your upfront costs.

As a family business, we pride ourselves on honesty, craftsmanship, and treating every customer like a neighbor. That’s why we’ve become one of the top performers for GJGNY home projects on Long Island. Our upgrades not only save you money, they make your house feel more like home.
