Heat Pump Installation for Nassau & Suffolk County Homeowners
Heat pumps are transforming how Long Island homeowners heat and cool their homes. Instead of generating heat by burning natural gas or oil, a heat pump moves heat from one place to another using refrigerant, the same technology that powers your refrigerator. In cooling mode, it moves heat out of your home. In heating mode, it extracts heat from outdoor air (even cold air contains heat energy) and moves it inside. The result is a single system that handles both heating and cooling with remarkable efficiency.
Island Comfort HVAC has been installing heat pumps on Long Island since 2014, when the technology matured enough for reliable cold-climate performance. Modern air-source heat pumps from Carrier, Lennox, and Mitsubishi deliver full heating capacity at temperatures well below freezing. The Carrier Infinity 24VNA0 heat pump operates efficiently down to 0 degrees Fahrenheit, and Mitsubishi’s Hyper-Heating Inverter (H2i) units maintain capacity down to -13 degrees Fahrenheit.


For Long Island homeowners, the primary benefit is efficiency. A heat pump moves 2 to 4 units of heat for every 1 unit of electricity it consumes, which is measured as a Coefficient of Performance (COP). Compare that to a gas furnace, which generates at most 0.96 units of heat per unit of gas (96% AFUE). This means a heat pump can reduce your heating costs by 40% to 60% compared to an older oil system and 20% to 40% compared to a new gas furnace, depending on your electricity and gas rates.
Ground-source (geothermal) heat pumps take efficiency even further by exchanging heat with the earth rather than the outdoor air. Ground temperatures on Long Island stay between 50 and 55 degrees year-round, providing a more stable heat source in winter and heat sink in summer. Ground-source systems achieve COP values of 4 to 5, making them the most efficient HVAC technology available. The tradeoff is higher upfront cost due to the ground loop installation, but federal tax credits and PSEG rebates can offset 30% or more of the total project cost.
We install both ducted and ductless heat pump configurations. If your home has existing ductwork in good condition, a ducted heat pump replaces your furnace and AC with a single outdoor unit and an indoor air handler. If ductwork is not available, a ductless mini split heat pump provides the same heating and cooling capability without any ducts. Multi-zone ductless systems offer room-by-room temperature control.
PSEG Long Island offers significant rebates on qualifying heat pump installations, and the federal Inflation Reduction Act provides a tax credit of up to $2,000 for qualifying heat pump systems. We track all available incentives and help you with the application process.

Our Heat Pump Installation Process
Energy Assessment
We evaluate your home’s heating and cooling loads, existing equipment, ductwork, and electrical service to determine the best heat pump configuration.
System Design
We design the system including equipment selection, ducted vs ductless configuration, backup heat requirements, and electrical upgrades if needed.
Rebate & Incentive Filing
Before installation, we identify all available rebates and tax credits and begin the application process.
Professional Installation
Our crew installs the heat pump system, including outdoor unit, indoor air handler or wall units, refrigerant lines, electrical, and controls.
Commissioning & Training
We commission the system in both heating and cooling modes, verify performance, and walk you through the operation and maintenance.

Same crew, start to finish.
No subcontractors. The team that starts your project is the team that finishes it.
Heat Pump Pricing on Long Island
Air-source heat pump installation on Long Island costs between $6,500 and $12,000. Ground-source (geothermal) systems range from $18,000 to $35,000 including the ground loop, but federal tax credits can reduce that by up to $10,500.
For air-source systems, a single-zone ductless heat pump runs $4,500 to $6,500. A ducted air-source heat pump that replaces your existing furnace and AC typically costs $8,000 to $12,000. Multi-zone ductless systems with 3 to 5 heads range from $8,000 to $15,000.
After accounting for PSEG rebates, federal tax credits, and annual energy savings, most Long Island homeowners recoup the additional cost of a heat pump over a traditional system within 5 to 8 years.
What Long Island Homeowners Say
“James came out the same day we called. Diagnosed the issue in 20 minutes, had our AC back running within the hour. His crew installed our whole system four years ago and it has been flawless. Cannot recommend enough.”
“We got four quotes for central air. Island Comfort was the only company that showed up on time, explained every option without pressure, and gave us a written quote the same visit. System runs perfectly. Fair price.”
“Our furnace died on the coldest night in January. James had a tech at our house by 9 PM and we had heat back by midnight. They did not gouge us on the emergency call either. Ended up replacing the whole furnace the following week. Professional start to finish.”
