• Be licensed in Massachusetts with manufacturer’s certificate of training within past 5 years
4. Customer and Building Requirements:
• Note: Installers are recommended to install ASHP system based on NEEP’s Cold-Climate Installation Guidelines
, which include ensuring any outdoor units have adequate clearance above historical average maximum snow depth
• This program is available to residential customers of HG&E for owner-occupied properties with 4 units or less. (Assistance is not granted to tenants renting or leasing the property. Customer must live at address where ASHP system is being installed).
• Installation address must currently use natural gas, oil or propane as primary heating fuel (unless new construction or gut-rehab) and have an active HG&E residential electric account.
• Customers who heat with oil or propane must submit past year of fuel use data to CET before audit (if available).
• To receive the higher Tier 2 ASHP rebate (provided if customer decommissions existing heating system), installer must indicate on post-installation form that existing heating system was decommissioned.
*Gas-Conversion Projects Only: In order for customers who are converting from natural gas to receive the higher Tier 2 rebate, customer must have their previous gas heating system decommissioned indefinitely by having the gas heating connection pipe cut and capped by a Massachusetts licensed gas plumber. Plumber must have valid gas permit for the project. Natural gas will not be available for heating load following ASHP conversion. Load transfer to other appliances subject to review and approval by HG&E. (Locations may be subject to additional requirements depending on gas service material and gas meter location(s)).
• Applicant's account must be in good standing with HG&E, (6- 12 month history of satisfactory payments) and there shall be no Municipal tax liens on the property. For homeowners with no prior HG&E billing history, Applicant may submit a letter of credit from their previous utility provider.
• Customer must submit pre-installation application which must be approved by HG&E before installing ASHP.
5. Free program-specific ASHP Energy Audit required before installation (or equivalent Manual J calculation)
6. Additional Terms and Conditions:
• To receive the Weatherization Rebate Adder, weatherization contractor must be licensed, the weatherization services must have been recommended in your energy audit, and weatherization work must be completed no later than 6 months after installing program-approved ashp system. Weatherization rebate adder is not available for new construction or gut-rehabs.
• At HG&E's option, the completed installation may be inspected by HG&E personnel or its representative to ensure compliance with the terms of this program.
• Customer is not eligible for any additional HG&E weatherization rebates for one year after project completion and is not eligible for any additional HG&E rebates for the ASHP system that is installed through this program. The Applicant is responsible for obtaining pricing, selecting a contractor, coordinating contractor scheduling and making payments to the contractor.
• HG&E reserves the right to change, suspend, or modify the terms of this program at any time, and reserves the right to inspect any installation. Gas service may be terminated for violation of any Program eligibility requirements.
• Neither HG&E, CET, their agents, or employees shall be liable for any claims, loss, expenses, or injury whatsoever for work performed under the Agreement. HG&E and CET make no and have not made any warranties or representations, express or implied, and do not hereby claim any representation, warranty, or covenant as to the design, installation, fitness for any particular purpose, merchantability, condition, quality, performance, durability, or suitability of the equipment (or any installation of installer thereof), or the work in any respect. HG&E and CET do not endorse, guarantee, or warranty the equipment, work, or any particular contractor, vendor, manufacturer, or product.

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.
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.
