FAQ: Home Energy Assessments in Somerville

Are home energy assessments worth the time?

 

Absolutely. For Massachusetts homeowners, a Mass Save assessment is one of the smartest decisions you can make, and it costs you nothing. This complimentary evaluation serves as your gateway to accessing substantial rebates, incentives, and financing options that can cover most, or even all, of your energy upgrade costs.

 

How much does it cost to have a home energy assessment through the Mass Save® program?

 

Absolutely nothing. The Mass Save program is already funded through a small charge that appears on your monthly utility bill. Since you’re already contributing to the program, taking advantage of the assessment and its benefits costs you nothing extra. There’s no catch, no hidden fees, and absolutely no obligation to move forward with any of our recommended upgrades. 

 

How much time does a home energy assessment take?

 

No more than two and a half hours, depending on the size of your home. An Endless Energy specialist will walk throughout the home, making recommendations for weatherization, including insulation and air sealing opportunities, along with HVAC and water heating upgrades. The technician will also provide instant energy-saving suggestions, such as smart thermostats, low-flow showerheads, aerators, and energy-saving power strips.

 

Am I required to complete all recommendations provided during the home energy assessment?

 

Nope! The assessment is purely informational and designed to give you a clear understanding of your home’s energy performance and available opportunities. What you choose to do with that information is entirely up to you. 

 

Who needs to be present during a home energy assessment?

 

We recommend and encourage that the homeowner/decision maker be present throughout the duration of the Home Energy Assessment. If the homeowner/decision maker is unavailable, someone who is knowledgeable about the home and at least 18 years old must be present.

 

Are home energy assessments in person or virtual?

 

Both! We work with your schedule and find the best time for a virtual or in-person Home Energy Assessment. You get the same benefits and quality of service with either option.

Based on 494 reviews
My experience with Endless Energy was outstanding! The initial visit is to discuss the conversion from natural gas to electric heat pump technology.

During the audit, I mentioned an issue with my existing heating system. Without asking, they diagnosed the problem and fixed it w/o charge. Amazing!

I'm currently reviewing a complete energy audit and a proposal that was personally delivered to my home and reviewed, with all questions answered!!! A special shoutout to Mike Heil, who prepared and presented the audit and quote.

Even the CEO gave me a follow-up call, thanking me and asking me to answer any questions!

A great company built with great people!!
Had an energy survey of our new home
Response from the owner:Thank you for the high praise! It's wonderful to hear that you're happy with our service.
We received an on-site visit and discussion on 11/13/25 regarding installation of a heat pump water heater. The technician told us we would receive a quote the next day. However, as of 12/15/25, we still have not received any proposal, despite calling the company at least three times. Each time, we were told the message would be forwarded, but there was no follow-up.

Based on this experience, communication after the site visit was very poor. It appears that smaller projects may not be a priority. If your project is not a large or high-profit job, be prepared for significant delays or no response.
Response from the owner:Hi there - I'm sorry to hear your experience. Can you email us directly at info@goendlessenergy.com and we'll be sure it gets to you immediately. It's possible we have a typo in an email address somewhere.
Response from the owner:Thank you for the high praise! It's wonderful to hear that you're happy with our service.
Tech was knowledgeable and resolved the problem quickley
Response from the owner:Thank you for the high praise! It's wonderful to hear that you're happy with our service.
Markus was very knowledgeable and helped explain each part of the inspection process; as well as our vulnerabilities in our systems and insulation
Response from the owner:Thank you for the high praise! It's wonderful to hear that you're happy with our service.
They were very kind and officiant workers. Only problem would be the lack of communication between myself and the electricians. Other than that the job was done well. All systems work and there was no mess left behind. Also a big thanks to the crew that made everything possible.

UPDATE 12/7/25: $26K Custom Comfort HVAC system performance update --- We've had the HVAC system for about 8 months and are now getting into real cold winter temps. The first floor and basement are ducted. Each of the 2 bedrooms on the 2nd floor has a ceiling mounted mini split.

We are deeply disappointed with the Custom Comfort mini splits installed by Endless Energy. They perform VERY poorly at sensing and responding to temperature changes based on specified comfort settings. The temperatures fluctuate wildly and differently between the 2 units, to the point we've had the technicians inspect the units more than once, but they are not capable of resolving the issue. So we keep playing an arbitrary game of raising and lowering the temp setting, hoping they stabilize.

Further, the unit in our main bedroom frequently makes fluttering and loud popping sounds throughout the day and night, often waking me from sleep. The other unit does make some fluttering sounds, but minimal popping sounds. We were told this is due to expanding and contracting in the vent/pipes. While this theory makes sense on some level, it makes absolutely no sense why the 2 units behave so differently when they're set to the same temps.

For a $26,000 job, we expected better quality products that can actually do their job of sensing and responding to temperature changes accurately, reliably and consistently. The Custom Comfort app is also very dated, slow and clunky.

Thankfully, we are still within our 1 year warranty period, and are hoping Endless Energy will continue to provide great service in helping us resolve this issue.

*************************
We had an exceptional HVAC experience with Endless Energy. They went above and beyond at every point in the install process, even when there were unexpected challenges such as equipment shortages or floor/ceiling joists not lining up as expected. In my opinion, the best way to tell if you're working with a great company is to see HOW they handle unexpected issues or delays. In our case, I have a noise sensitivity so it was vital that the ceiling units they installed be whisper quiet. They solved this problem by hanging the units from isolators. They understood our concerns about optics and placement of return vents and the heat pump. The team was exceptionally communicative and honored their promises. Endless Energy delivered an excellent customer experience with a full team of specialists, technicians and plumbers.

I highly recommend Endless Energy to anyone needing HVAC services because when things don't go according to plan (and let's face it, with these big projects, there's always something unexpected) you can count on them to find creative solutions to meet your needs and ensure your comfort.
Response from the owner:Thank you so much, Janine, for your wonderful review! We're delighted to hear that you appreciated our team's ability to tackle unexpected challenges and address your specific concerns about noise and aesthetics. Your kind words about our communicative team and creative problem-solving truly mean a lot to us.
Eydin was terrific! We needed to have parts replaced in our heating system. Eydin was careful to explain what he would be doing. He kept us updated as the work progressed and was very kind. Eydin made sure that the heat was working properly after he replace the parts and stayed to be sure that the house warmed up. We have had excellent experiences so far with Endless Energy. Both Gavin and Eydin certainly deserve 5 stars!
Response from the owner:Thank you for the high praise! It's wonderful to hear that you're happy with our service.
Marcus was well informed and explained the program and requirements easily.
Response from the owner:Thank you for the high praise! It's wonderful to hear that you're happy with our service.
