wasted energy and money.

Plus we have program partners who will help to coordinate your project from start to finish—making it even easier to save energy and money.

Frequently Asked Questions

In order to qualify for the National Grid’s Total Home Comfort Program, there are a few requirements that you must meet. Firstly, you need to be a current National Grid residential gas heating customer. Secondly, your home must be located within the National Grid Metro NYC and Long Island gas service area. Thirdly, you must reside in a one to four-family home. Lastly, you will need to work with an approved National Grid Partner to access the program. By meeting these requirements, you can take advantage of the program and receive weatherization services to enhance the energy-efficiency of your home.

Our approved program partner will perform a complete energy audit of your home and identify potential areas where thermal insulation is required to be installed. They will then work with the insulation contractors to assess how much thermal insulation is needed to apply across walls & ceilings. Once the energy assessment is complete, our program partner will get the quote and start with the rebate financing process.

The insulation rebates are calculated as per the energy savings that you are going to get from thermal insulation installation. Our program partner will provide you with an estimate on rebates which you can earn on your specific project.

The Total Home Comfort Partners are energy service providers who will make all arrangements to develop your project, install the measures, and submit the application details for rebate reimbursement.
