A recent customer said Mike and crew upgraded their HVAC with heat pumps, new air handlers, a mini split and a 50-gallon water heater in a 3-day project, and that a recycling team removed the oil tank. Weathervane Home Services describes itself as a Massachusetts and New Hampshire home-performance contractor doing Mass Save and NHSaves energy work: home energy assessments, insulation and air sealing, and heating, cooling and heat pump installations. Its website says it was started by Dan Carroll, Matt Hammer and John Lanzi. A recent customer had additional insulation and air sealing done, including foam board work in the crawlspace under the kitchen. A recent customer said Rodney and Jose insulated the attic and the crawl space under the addition, and that an electrician replaced the bathroom fan. A recent customer said Jeff Benzan and Manny Jiamenz did attic work and installed a vent through the Mass Save program, and handled a change the husband added. A recent customer said Spencer and Davin replaced a gas furnace with a heat pump system, and that Spencer walked through how the new system works. A recent customer went from a loud 18k BTU air conditioner to a unit that whispers, and said Weathervane sent a company out to remove the old unit, repair the wall and repaint. A recent customer said Rob went through the whole house and explained in detail what was needed to make the home efficient. A recent Reddit commenter said the person who came for an audit seemed legit. In an April 2025 r/massachusetts thread, a commenter who had worked with Weathervane said they were really happy. Its Massachusetts HVAC licence, number 957-SM-B, held by Weathervane Home Services, is active on the state registry. It holds 4.9 stars from 368 Google ratings. Its BBB grade is C-, and the BBB lists one complaint. A recent customer with a Fujitsu system said odors, intermittent hissing and reduced performance followed a shutdown for asbestos remediation, and that annual service they requested never occurred. That customer said they followed a recommendation to have another HVAC contractor remove and reinstall an indoor unit and were not told it could affect warranty-related labor. A recent customer said garbage was left around the outside of the house after insulation work and that basement insulation was left hanging from the ceiling. That customer said the return visit came a month later, by someone without the tools needed to fix it. A 2026 customer said that after going through inspections for insulation, they never heard back. A 2025 customer said part of the home was left unlocked despite instructions and insulation material was left in the driveway. That 2025 customer said an inspector requested through Mass Save showed them sloppy and ineffective work.
“I recently had Weathervane come to my house for an audit and the guy seemed legit.”
“not all mass save auditors are made the same. I’ve worked with Weathervane. I was really happy.”
Response to the Owner's Reply: My review reflects my personal experience and the timeline of events. My concern has never been whether the Fujitsu manufacturer's parts warranty remained active, but with Weathervane's communication, recommendations, and post-installation support. My system operated properly until November 2025. Following asbestos remediation, the system was shut down and indoor heads were replaced. Once the system was returned to service, I experienced odors, intermittent hissing, and reduced performance. Those issues continued for months, which is why I contacted Weathervane in May 2026 requesting annual service so those concerns could be investigated before any later renovation work. That service never occurred. Later, I followed Weathervane's recommendation to use another licensed HVAC contractor to temporarily remove and reinstall one indoor unit to save money. At no point was I informed that this decision could later affect Weathervane's willingness to perform warranty-related labor or create a dispute over service responsibility. Had I been told that before making my decision, I would have hired Weathervane despite the additional cost. I believe that was material information that should have been disclosed before I acted because it directly affected my ability to receive service afterward. This recommendation was communicated to me during a phone call rather than in writing. Because Weathervane was aware that I am legally blind and that I rely on email and text communications whenever possible for accessibility and documentation, I believe providing this important information in writing would have helped ensure I fully understood the potential consequences before making my decision. As a legally blind and disabled homeowner, I relied on that advice. After exhausting every effort to resolve this matter, I sought assistance from the Massachusetts Low-Income Energy Program, the Executive Office of Housing and Livable Communities (EOHLC), Fujitsu, my State Senator's office, and the Better Business Bureau. While Weathervane emphasizes its records and interpretation of events, my review reflects the experience I actually had. I would not have spent months gathering documentation or asked multiple state agencies, Fujitsu, my State Senator's office, and the Better Business Bureau to review this matter if I did not genuinely believe I had not been provided information that would have materially affected my decision. That remains the central issue for me. I stand by my review because it accurately reflects my experience, and I am confident the appropriate agencies and program administrators will evaluate the facts independently.
Had additional insulation and air sealing done to our home and these guys were nothing short of perfect. The 2 that came (totally forgot their names but they were in truck 1) were extremely professional to deal with and the work they did was phenomenal. The craftsmanship and attention to detail was second to none, especially the foam board work they did in the crawlspace under our kitchen. Everything was kept extremely clean as well. 100% reccomend them for any work for your home!
It was a pleasure working with Damian! He did a phenomenal job with the installation of our bathroom fan. He was professional, on time and very polite. Made sure our space was clean and neat after he finished his work. Highly recommended - thank you weathervane for sending him our way!!
Jeff Benzan & Manny Jiamenz were phenomenal, courteous, polite, careful of my home and very thorough with their clean up. They showed up at 8am, then Jeff took the time to explain everything to me prior to the work and again after they were done. They were especially careful not to let the dog out and courteous of the noise while i was working at home. My husband threw in a change and they handled it without a hitch. Weathervane through the Mass Save program put installation in my attic & installed a vent. It was 90 degrees today and they completed the work without a complaint. I would high recommend this company. Ask for Jeff and Manny!
We had the initial energy assessment with the technician Robert and he was amazingly knowledgeable, efficient at assessing our needs and gave us a price range of what the work will entail to hopefully create a more energy-efficient situation for our home.
