Nassau County has approximately 1.4 million residents living in 450,000 households. The housing stock is predominantly single-family homes built between 1945 and 1975, during the post-war suburban boom. These homes present consistent HVAC challenges: aging ductwork, insufficient insulation by modern standards, and heating and cooling systems that are often 15 to 25 years old.

We have completed more than 2,100 HVAC projects in Nassau County since 2009. From ranch homes in Levittown to victorians in Garden City, from waterfront properties in Long Beach to colonials in Syosset, we know the housing stock and the unique requirements of each community.

Nassau CountyHousing & Demographics

Nassau County is one of the most densely populated suburban counties in the United States. The average home is approximately 1,800 square feet, though sizes range from 1,200-square-foot Cape Cods in Levittown to 4,000-square-foot colonials in Garden City and Syosset.

Most Nassau County homes are heated by natural gas, with a significant number of older homes still using oil heat. The county has seen a major trend toward oil-to-gas conversions, driven by lower gas prices and cleaner operation. We have performed hundreds of oil-to-gas conversions across Nassau County.

Electricity rates on Long Island are among the highest in the nation, which makes system efficiency a top priority for Nassau County homeowners. High-efficiency furnaces (96%+ AFUE), variable-speed AC units (18+ SEER2), and heat pumps are increasingly popular choices.

HVAC Considerations for Nassau County

Nassau County homes built in the 1950s and 1960s often feature Cape Cod or ranch layouts with limited attic space. Installing ductwork in these homes requires creative routing through closets, soffits, and floor cavities. Our crew has extensive experience with these layouts.

The proximity to the ocean affects HVAC equipment in southern Nassau County towns like Long Beach, Freeport, and Massapequa. Salt air accelerates corrosion on outdoor condensers and heat pump units. We recommend Carrier’s Coastal Protection coating for homes within 2 miles of the shore.

Many Nassau County homeowners are eligible for PSEG Long Island rebates on high-efficiency HVAC equipment. We track current rebate programs and handle the application paperwork as part of every installation.
