Home Efficiency Services

Greater New York not only experiences the full spectrum of seasons throughout the year, but we also see some of the highest utility rates in the country! This is why home improvements, like insulation and air sealing, are crucial for homes in the area. 

Green Team LI specializes in making Greater New York homes comfortable, healthy, and more affordable to heat and cool with our whole-home efficiency services. Whether you have a historic colonial home or a split level, our team can find a reliable, long-lasting, and affordable solution that meets your needs.

Why You Should Always Start with an Energy Audit 

Before you make any efficiency upgrades, it’s important to start with baseline knowledge of your home’s current performance and where it’s using the most energy. At Green Team LI, we do this with a comprehensive energy audit

Our team of certified energy auditors will come to your home and collect data with specialized tools, like infrared thermal imaging and blower door testing. This gives us an opportunity to discover areas of air leakage, poor insulation, and other factors that could be contributing to inefficiencies in your home. From there, we can build a customized plan that will help lower your energy bills, increase your home comfort, and improve indoor air quality. 


High-Performance Insulation & Air Sealing 

Insulation and air sealing work together to protect your home from the outside elements throughout every season of the year. By helping your home maintain stable indoor temperatures, reducing air leaks, and providing moisture control, these two essential services go hand in hand to optimize your home’s performance.  

At Green Team LI, we offer several types of insulation for Greater New York homes, including:

  • Spray Foam InsulationSpray foam insulation is an all-in-one insulation and air sealing product that comes with numerous benefits and can even improve the structural integrity of your home. 
  • Cellulose InsulationMade from recycled materials and treated to be fire, mold, and pest resistant, cellulose insulation is a great option for many homes. 
  • Foam Board InsulationWith a rigid, airtight structure, foam board is a durable type of insulation offering a high level of efficiency.
  • Air SealingSealing gaps and cracks throughout your home strengthens its thermal barrier and enhances insulation performance. 

Make Your Efficiency Upgrades More Affordable with Tax Credits & Rebates! 

Because home efficiency is such a crucial component in your home’s performance, there are several incentive programs that can help make upgrades more affordable. Green Team LI stays up to date on the tax credits and rebates available to homeowners throughout Greater New York and is a participating contractor with PSEG and NYSERDA. Many residents qualify for a free energy audit and can save thousands of dollars on insulation and air sealing upgrades!

Incentives are often funded by government programs, which means they are subject to regular changes. When our team goes over your energy audit report with you, we’ll also go over what services are eligible for tax credits or rebates to help you maximize your savings.
