Residential furnace, central AC, heat-pump, and ductless projects across Nassau County with written scope, pricing, and scheduling confirmed before authorized work.
HVAC installation begins with the home's heating and cooling goals plus a review of load, distribution, electrical or fuel service, venting, drainage, controls, equipment location, access, and applicable permits. The written proposal identifies the selected equipment and project-specific scope.
We evaluate equipment options from established manufacturers, including Carrier, Lennox, Trane, Mitsubishi, Daikin, Rheem, and Goodman. The written proposal identifies the selected equipment, sizing method, permit responsibility, warranty-registration responsibility, included work, and price before installation begins.

Professional HVAC installation in every Nassau County community
Furnace, central AC, heat-pump, and ductless projects sized with a Manual J load calculation, quoted in writing with permits and scope spelled out, and confirmed by ZIP code when you call.
Home+ Air & Heat installs residential heating and cooling across Nassau County and Western Suffolk from our Jericho shop, including Hicksville, Garden City, Levittown, Massapequa, Syosset, Farmingdale, and the Huntington and Islip areas. Coverage is confirmed by ZIP code when you call, and the written proposal states equipment, scope, permits, and price before anything is ordered.
Plan on $4,500–$12,000 for a furnace or central AC project and $5,000–$18,000 for a heat-pump or multi-zone ductless project. The spread comes from capacity, efficiency, ductwork and electrical work, equipment location and access, venting or drainage, and permit requirements — which is why the final number comes from a site visit and a Manual J load calculation, not square footage.
Yes, and doing both together is usually the cheaper path. A shared furnace-and-coil or heat-pump changeout reuses one set of line-set, electrical, and duct connections instead of paying for that labor twice, and it lets us size both sides of the system to the same load calculation rather than matching new equipment to an aging partner.
We cover Western Suffolk, including the Huntington, Babylon, and Islip areas, and confirm your specific ZIP code before booking rather than promising blanket county coverage. Eastern Suffolk and the East End are outside the service radius. Nassau County is covered in full.
A straight changeout of a furnace, central AC, or heat pump is typically a one- to two-day job. Projects that add ductwork, relocate equipment, upgrade electrical service, or wait on a town permit or inspection run longer, and the proposal states the expected schedule for your address so you know what to plan around.
Homes with sound ductwork and gas service usually stay cheapest on a high-efficiency furnace with central AC. Heat pumps make sense when you want one system for heating and cooling and can review PSEG Long Island rebate eligibility for properly sized equipment. Ductless is the answer for additions, converted garages, finished attics, and homes with no ducts at all.
PSEG Long Island's Home Comfort program is active for qualifying heat pumps and heat-pump water heaters, and eligibility depends on the equipment, sizing documentation, and a participating partner performing the work. We verify the program and amount in writing for your address and selected equipment before you buy rather than quoting a rebate you may not qualify for.
