## Mini split cost on Long Island

| What is installed | Low | High |
| --- | --- | --- |
| Ductless mini split, one or two rooms | $4,500 | $11,000 |

_Installed, before rebates. These are the New York City bands times a regional factor of 1 for NY suburbs. Judgement: Long Island installer ranges (one zone $5,000-$8,000, three zones $10,000-$15,000) run about 6 to 9 percent above the NYC installer midpoints, which is inside the gap between the two NYC installers themselves, so no discount or premium is applied; Westchester and Hudson Valley installer prices were not found, so this rests on Long Island only.

## Rebates for PSEG Long Island customers

1 program for PSEG Long Island customers is listed as open. Pause and waitlist status could not be confirmed from a public live source for any utility. The New York Clean Heat manual (v3, effective 2026-09-01) lists full amounts for all six NY utilities and no public notice of a pause was found; Con Edison and National Grid ration money through quarterly contractor allocations (official Clean Heat meeting summaries say contractors "should only submit applications for incentives within their allocated incentive budget"), so a homeowner can be told no money is left through a given contractor. Treat "open" as "listed and not publicly paused", and call the utility or contractor before promising a rebate.

## About mini splits on Long Island

Nassau County has a cold-winter climate with humid summers, so a heat pump does both jobs. The housing is mostly single-family homes, many Cape and ranch houses built after World War II, with an oil or gas boiler and radiators or baseboard. Homes without ducts are common, which is why ductless systems come up often here.

Suffolk County sits in a cold-winter climate zone, with Long Island Sound and the Atlantic keeping it a little milder than inland New York. Much of the housing is single-family homes built from the 1950s on, many heated with oil or natural gas, and many with a furnace and ducts. Older homes with radiators or baseboard heat usually point to ductless units.
