HOW TO APPLY:

Step 1: Apply

Submit the pre-application, located in the Program Resources section below, to see if you meet the inital eligibility requirements. 

Step 2: Receive an Energy Audit

If your pre-application is approved, we will provide you with instructions to schedule a free program-specific ASHP energy audit through our audit partner, the Center for EcoTechnology (CET). CET will provide you with weatherization recommendations and determine your home's heating requirements. 

Step 3: Obtain Proposals

Provide your chosen installer with your home's heating requirements that were determined by CET as well as the program eligibility criteria (located in the Program Resources section below). Also consider obtaining a quote from a licensed contractor for the weatherization recommendations from your audit report.

Please note: It is recommended that you have a contract with any contractor you decide to work with in order to protect you from any damages that may occur as a result of the project, and that the contract is in line with the Massachusetts Home Improvement Contractor Guaranty Fund. 

Step 4: Assess Your Options

Submit your proposals to CET so they can advise you on the various costs and benefits for completing the weatherization recommendations before you install the ASHP. They will also review the ASHP proposal you choose to move forward with to ensure it meets the program eligibility requirements. (Be sure to provide CET with the AHRI number for each unit being considered as well as the size of any additional electric heating elements). 

Step 5: Request Financial Assistance (Optional)

Submit the Residential Energy Conservation Program application (below) if you would like to request financial assistance at 0% interest to help with your installation costs ($100 administrative fee required).

Step 6: Have the Work Completed

Complete the weatherization recommendations from your audit report if you have decided to move forward with them. Then have your new ASHP system installed. 

Step 7: Receive Payment

HG&E will mail you a check for your ASHP rebate, weatherization rebate (if applicable) and RECP assistance approximately three weeks after your ASHP system has been installed and we receive all required post-installation paperwork from your installer.

FAQ's

What Are Air Source Heat Pumps and Mini-Splits?

Air source heat pumps, sometimes referred to as mini-splits, are an energy-efficient electric heating and cooling system type becoming more popular in cold climates due to recent advancements in technology. Click here to learn more about this technology.

What Does the ASHP Energy Audit Entail? 

The ASHP energy audit is specifically designed to prepare homeowners who are installing a whole-home ASHP system to help you assess the benefits of improving your building's weatherization before ASHP system is installed. These weatherization improvements can include improving your insulation, air sealing and duct sealing which can reduce the amount of hot and cold air that escapes from your home, therefore reducing the amount of energy needed to heat and cool your home. Weatherizing your home can also reduce the size of the heating system that you will need, reducing your installation costs. CET will provide you with the estimated annual heating and cooling cost savings for moving forward with each recommendation. They will also determine the size of the heating system you will need based on your current building charecteristics, and will let you know what size system you would need if you moved forward with their weatherization recommendations. (If you currently heat with oil or propane, please provide CET with your fuel receipts from the past year so they can better estimate the annual energy savings estimates for the various recommendations from your audit report). 

Why Should I Receive Multiple Proposals from an Installer?

Weatherizing your home before installing a new heating system can often reduce the size of the system that's needed, therefore reducing installation costs. When you reach out to a qualifying installer, you will be able to provide them with the size of the heating system you need based on your current building characteristics, as well as the size of the system you would need if you move forward with the weatherization recommendations from the audit report. The installer will then be able to create two proposals for you to help you understand any reduction in your installation costs for weatherizing your home before installing the system. 

How will CET Help Me Assess My Options?

CET will work with you to review your ASHP proposals and any weatherization proposals. They will provide you with both an upfront and lifetime cost-comparison based on whether or not you move forward with the weatherization recommendations. The cost-comparison will take into account the rebates available through this program, your historical heating bills, and the installation costs from your proposals to help you understand the financial benefits of improving your building's weatherization before installing the ASHP system. 

What Post-Installation Paperwork Does My Installer Need to Submit?

HG&E will need to receive a completed ASHP post-installation form as well as a weatherization post-installation form (if applicable) from your installer(s) after the work has been completed. CET will provide your chosen installers with these forms. 

When will My Installer(s) be Paid?

It is up to you to pay your installer(s) for any work that is completed. Because it will take at least three weeks for you to receive the payment from us after the ASHP system is installed, it is recommended that you review the payment terms with your chosen installer, including the payment due date for the work they performed. 

Program Background

This program was designed to support the installation of high-quality, highly-efficient and optimally designed ASHP systems that operate year-round in cold climates and to help achieve Massachusetts goals of reducing greenhouse gas emissions by replacing higher emitting heating fuel sources with cleaner and more efficient electric heating and cooling systems.
