HVAC Installation Price Ranges

Honest, upfront price ranges for the most common installations we perform across Long Island. Use this page to plan your project — then schedule a free in-home consultation and we will provide a written quote tailored to your home, your equipment selection, and the condition of your existing ductwork and electrical.

These ranges cover ductless mini-splits, central air conditioning, heat pumps, gas furnaces, air handlers, and indoor air quality upgrades. They are starting points, not bottom-line quotes. Final pricing depends on the equipment you choose, removal of the old system, permits, and any modifications needed during installation.

Transparent Pricing

What These Numbers Mean

Most HVAC contractors will not show you a price until they are standing in your home. We take a different approach. The ranges below give you a realistic starting point for budgeting your project, so you can plan with confidence and avoid the sticker shock that some homeowners experience after a sales call.

Every installation is different. The size of your home, the condition of your existing ductwork, the layout of your mechanical space, and the brand and efficiency tier of the equipment all affect the final number. We will walk you through every line item during your free consultation so you understand exactly what you are paying for and why.

If you are weighing a new system against a costly repair, or if you are simply planning ahead for an eventual replacement, these ranges should help you start the conversation with realistic numbers. Reach out any time and we will set up a no-obligation visit.

What Affects Final Pricing

Factors That Move the Needle

Equipment Tier and Efficiency
Higher SEER2 / AFUE / HSPF ratings, variable-speed compressors, and inverter-driven systems cost more upfront but lower long-term operating costs.
Ductwork Condition
Existing ducts that need sealing, resizing, or replacement add to the project. We assess every system before quoting.
Electrical Requirements
Some installations require service-panel upgrades, dedicated circuits, or new disconnects depending on the equipment.
Removal of Old Equipment
Disposal of refrigerant and recycling of the old system is included in our installation work.
Permits and Inspections
Town and Suffolk County permits are pulled and managed by us. Costs vary by jurisdiction.
