Revenue model

1. Energy Audits: Comprehensive home energy assessments that evaluate energy performance, identify inefficiencies, and provide customized recommendations. Many homeowners qualify for free audits through NY State and utility programs (PSEG, NYSERDA). Audits are a requirement for most rebate programs and serve as the entry point for all other services.
2. Insulation and Air Sealing Services: Installation of various insulation types (spray foam, cellulose, foam board) and air sealing services to improve building envelope performance. Revenue is project-based, typically ranging from hundreds to thousands of dollars depending on home size and scope of work.
3. HVAC Installation and Service: Installation and maintenance of heating and cooling systems including air source heat pumps (ducted and ductless mini splits), furnaces, air conditioners, and oil to gas conversions. Includes annual maintenance plans and service agreements for ongoing revenue.
4. Solar Panel Installation: SunPower solar panel and battery storage installation services. Revenue from equipment sales, installation labor, and financing arrangements. Partners with SunPower as authorized dealer and offers various financing options including Mosaic loans, SunPower leases, and third-party financing.
5. Ductwork Services: Duct sealing, replacement, and insulation services to improve HVAC performance and reduce energy loss.

Core offering

Green Team LI is a Home Performance with ENERGY STAR contractor that begins every project with a comprehensive energy audit using blower door testing and infrared thermal imaging, then delivers targeted upgrades based on audit findings. Offerings span three categories: heating and cooling services (air source heat pumps, ductless mini-splits, high-efficiency heating systems, central air conditioning, ductwork, and oil-to-gas conversions); home efficiency services (spray foam, cellulose, and foam board insulation, air sealing, building envelope work, and indoor air quality improvements); and solar services (SunPower panel installation with optional battery storage). The company is an authorized SunPower dealer and assists homeowners in navigating NYSERDA, PSEG Long Island, Con Edison, and Inflation Reduction Act incentives.

Product overview

Green Team LI is a home comfort and efficiency contractor offering a comprehensive suite of services organized around energy audits, heating and cooling, home efficiency, and solar. The core offering begins with energy audits that use blower door testing and infrared thermal imaging to assess whole-home performance. Based on audit findings, customers can engage services across three main categories: (1) Heating & Cooling including air source heat pumps, ductless mini-splits, furnaces, air conditioning, ductwork, and oil-to-gas conversions; (2) Home Efficiency encompassing spray foam, cellulose, and foam board insulation, air sealing, building envelope work, and indoor air quality services; and (3) Solar with SunPower panels, battery storage, and associated financing. All services can be bundled with rebates and incentives navigation through programs like NYSERDA, PSEG, and the Inflation Reduction Act.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Sunrun: Largest U.S. residential solar, battery, and home energy company; overlaps with Green Team LI's solar + battery storage offering but operates at national scale and primarily through solar leases/PPAs rather than whole-home audit-led GTM.
• Tesla Energy: Residential solar and Powerwall battery installer integrated with Tesla vehicles and software; competes with Green Team LI's SunPower-based solar offering in the NY metro market at a national-brand price point.
• ADT Solar (formerly Sunpro Solar): National residential solar installer leveraging ADT's brand and customer base; competes in NY for the same solar-only and solar+battery homeowner segment that Green Team LI serves.

Regional players

• Trinity Solar: One of the largest regional residential solar installers in the Northeast U.S., operating across NY, NJ, CT, MA, and other states; directly comparable geographic and customer overlap with Green Team LI's Long Island focus.
• Revision Energy: Northeast U.S. (Maine, New Hampshire, Massachusetts) solar, heat pump, and energy efficiency contractor; comparable in combining solar installation with heat pump and weatherization services for homeowners.
• Momentum Solar: Direct-to-consumer residential solar installer active in the Northeast including NY/NJ/CT; comparable sales-led, in-home consultation GTM, though without the whole-home energy audit overlay.

Direct peers

• Sealed: Residential home energy efficiency company that performs whole-home assessments and then funds and manages insulation, air sealing, and HVAC upgrades — closely comparable to Green Team LI's home efficiency service line and audit-led GTM motion.
• PosiGen: National residential solar and energy efficiency contractor that, like Green Team LI, pairs solar installation with weatherization and HVAC upgrades for homeowners, often using state and utility incentive programs to drive affordability.

Emerging players

• Renu Energy Solutions: Carolinas-based residential solar, battery, and energy efficiency contractor; comparable in bundling whole-home efficiency and solar under one contractor, though operating in a different regional utility market.
• BlocPower: Building decarbonization company focused on energy efficiency and heat pump retrofits in residential and small commercial buildings, leveraging state and utility incentives — comparable in mission and incentive-driven model, though with a stronger software/data overlay.
