Many residential ducted heat-pump replacements use a $7,500–$15,000 planning range. Ductless, whole-home conversion and hybrid projects need their own scope—the selected winter capacity and distribution plan matter more than nominal tonnage.
Planning ranges are not quotes. Capacity, matched equipment, ducts or zones, backup strategy, electrical work, site conditions, permits and authorized scope control the written project price.

Ducted heat-pump replacement
$7,500–$15,000
A planning range for many residential ducted heat-pump replacements using serviceable distribution. Capacity, matched equipment, controls, backup heat, electrical work and duct corrections determine the written quote.
Ductless single- or multi-zone project
Zone count first
Indoor-unit count, room loads, line-set paths, condensate routing, electrical work and outdoor-unit combinations make ductless work a separate scope—not a central-system price with different equipment.
Whole-home cold-climate conversion
Design first
Replacing fossil-fuel heat requires a room-by-room load, selected low-temperature capacity, distribution plan and explicit backup or balance-point strategy before a useful price can be compared.
Dual-fuel, hybrid or distribution redesign
Design first
A retained furnace, new air handler, duct changes, zoning, electrical upgrades or multiple systems create a coordinated project. Require controls and operating sequence in the proposal.
Installed-cost drivers
Heating and cooling loads, exact indoor/outdoor match, low-temperature output, efficiency tier and controls determine which system is being priced.
Existing duct condition, return-air capacity, static pressure, zoning, indoor-unit count and line-set routes can change both equipment and labor.
The selected unit's capacity at the project's design temperature, balance point and auxiliary or retained-heat strategy must be resolved for the home.
Panel capacity, breakers, disconnects, equipment location, drainage, access, removal, permits and program documentation affect the complete installed scope.
Written estimate checklist
DOE and ENERGY STAR guidance centers proper sizing, airflow, ducts, refrigerant charge and installed performance. Ask each bidder to document the same responsibilities.
Cold-climate design
A cold-climate proposal should connect the home's heating load to the exact system's capacity at relevant outdoor temperatures. It should also state what happens below the balance point and how auxiliary or retained heat is controlled.
Choose the right next step
Start with diagnosis when the failure is not known. Compare a documented repair and system condition with replacement instead of deciding from age alone.
Start with heat-pump repairUse the conversion guide to compare full electrification, retained backup, duct and electrical scope, operating assumptions and current program requirements.
Plan a furnace conversionDuctless design starts with room loads, indoor-unit locations and line-set paths. Keep that scope separate from a central ducted replacement.
Plan a mini-split projectReview the current Long Island program rules before equipment is selected or an estimated incentive is subtracted from the installed price.
Review 2026 rebate guidance2026 incentive reality
PSEG Long Island's 2026 announcement confirms current Home Comfort requirements, including a defined Manual J sizing relationship and rebate caps. Exact equipment, project type, income tier and current program rules still control eligibility. The former federal 25C home-improvement credit ended for property placed in service after December 31, 2025.
Project sequence
The schedule is confirmed after the design and work scope are known. No generic one-day promise substitutes for a complete project plan.
Document loads, distribution, electrical capacity, site constraints, current equipment and homeowner priorities.
Choose exact matched equipment using loads, low-temperature performance, airflow or zones and backup strategy.
Review inclusions, exclusions, base price, conditional incentives, permits, timing, payment terms and written coverage.
Complete the approved work, then document airflow, refrigerant, controls, auxiliary heat and homeowner operation as applicable.
Local project coverage
Home+ is based in Jericho and serves covered Nassau County and Western Suffolk County ZIP codes. Dispatch confirms service-area fit and current availability for the project address.
Ducted cold-climate systems, ductless mini-splits and oil-or-gas conversions across covered Nassau County and Western Suffolk ZIP codes — written scope and pricing after an in-home assessment.
Home+ Air & Heat installs ducted and ductless heat pumps throughout covered Nassau County ZIP codes and Western Suffolk, from our base in Jericho. Projects include cold-climate ducted replacements, single-zone and multi-zone ductless systems, whole-home conversions from oil or gas, and hybrid setups that keep the existing furnace as backup heat. Every proposal is written after an in-home assessment of the load, distribution and electrical capacity.
Most Nassau County projects plan around $9,000–$18,000 for a whole-home or ducted cold-climate heat pump and roughly $4,500–$7,500 per zone for ductless mini-splits. The final number depends on capacity at winter design temperature, matched indoor equipment, duct or line-set routing, electrical panel work, site access, permits and the authorized scope. Planning ranges are not quotes.
Yes, when the equipment is selected for cold-climate performance rather than nominal tonnage. Long Island's winter design temperature means capacity has to be verified at low outdoor temperatures, and the proposal should state the backup or auxiliary heat strategy. A hybrid system that keeps a gas furnace for the coldest hours is a common Nassau County answer for homes with existing ductwork.
Ductless mini-splits fit the housing stock well — pre-war Garden City and Rockville Centre homes with no duct space, Levittown and Hicksville additions and finished attics, and rooms the existing central system never satisfied. Each zone heats and cools, so a mini-split solves a hot bedroom in July and a cold room in January with the same equipment. Zone count, indoor head type and line-set routing are confirmed onsite.
The PSEG Long Island Home Comfort program offers $4,000 at market rate or $7,500 income-qualified as a flat heat-pump incentive, available through a Participating Partner with Manual J sizing between 100% and 120% of load. Eligibility is confirmed with the written proposal, and the former federal 25C credit is not available for property placed in service after December 31, 2025.
A straightforward ducted replacement is often one to two days. A multi-zone ductless project, a full conversion from oil or gas, or a job that needs panel upgrades or duct rework runs longer, and permit and inspection timing varies by village or town. The anticipated sequence, shutdown period and restoration responsibilities are stated in writing before work is authorized.

Heat-pump installation FAQ
Home+ uses $7,500–$15,000 as a planning range for many residential ducted heat-pump replacement projects. It is not a quote or a universal whole-home conversion price. Capacity, exact equipment, ducts or zones, backup heat, electrical work, access, permits and the authorized scope determine the written price.
Sometimes, but not by assumption. The design should compare room-by-room heating and cooling loads with the selected system's capacity at relevant outdoor temperatures, then state the balance point and backup strategy. Some homes use full electrification; others retain or add auxiliary heat.
Cold-climate heat pumps are designed for low-temperature operation, but capacity and efficiency vary by exact model and outdoor temperature. Ask for the selected system's low-temperature performance, the home's design load and the planned backup or no-backup strategy in writing.
A serviceable duct system can support central distribution, while homes without ducts or rooms with distinct loads may suit ductless zones. Existing duct condition, room loads, indoor-unit locations, aesthetics, controls and installation routes should decide the design—not a blanket rule.
PSEG Long Island's 2026 Home Comfort announcement confirms a current program with project requirements, including sizing and rebate caps. Eligibility and amount depend on the exact equipment, sizing, project type, participating-contractor process, income tier and current program rules. Keep any estimated rebate separate from the base installed price and confirm it in writing before authorization.
The former federal 25C Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025. The current IRS Form 5695 instructions say it cannot be claimed for later property, so a 2026 proposal should not subtract it.
Timing depends on the approved scope. A ducted equipment replacement, a multi-zone ductless project, a whole-home conversion and a job requiring panel or duct work are different schedules. Ask the contractor to state the anticipated work sequence, shutdown period, inspections and restoration responsibilities in writing.
Warranty terms vary by manufacturer, exact model, registration, installer and maintenance requirements. The proposal should separate manufacturer parts coverage from contractor labor coverage and identify who registers the equipment, deadlines, exclusions and service responsibility.
