HVAC reviews in Canton, Massachusetts

My heating system technician, Tom Stinchfield, was very experienced, thorough, hard working, and personable. Green Energy Mechanical’s back office was also good to work with. Txs!

I had a very good feeling about working with Irvin On my old Furnace. He was giving me a lot of good information and would stop and help explain what was happening if I didn’t understand. I feel really well served by your company as well as the people who I’ve met from your company.

I give Irvin My Highest references and will recommend your company to my friends in the neighborhood. Thank you all.

TLDR: FOR YOUR OWN SAKE, GET YOUR WORK DONE ELSEWHERE. WASTED 2 MONTHS OF MY TIME AND STILL HAVE MY MONEY.

They are sloppy, unprofessional thieves. They took my money and took my time. I accepted a quote, signed the contract, and gave 50% down payment. After waiting for 4 weeks to get a start work date, they contacted me and said they misquoted me and they need to raise the quote price significantly.

They still have my money. They haven't returned my calls. When I call, I have to shuffle through AI agents before I can finally talk to a person who always ends up telling me I’ll ’get a call back later’.

I’ve never had to leave a review like this- I almost exclusively write positive reviews so when I tell you this place sucks, believe me.

Kevin, Shaun- whoever needs to hear this; get it together. Honor the quote.

Our two-year-old heat pump system from Green Energy Mechanical stopped working in October 2025 due to a leaking coil in the indoor air handler, leaving us without heat for several weeks while we waited for parts from the manufacturer, GE. It was a very difficult situation, especially as the colder weather set in.

Green Energy Mechanical evaluated the problem, and when it became clear that the replacement coil wouldn’t arrive in a reasonable timeframe, they replaced the entire air handler unit at no cost since the system was still under GE’s 10 year warranty. Our system is now working properly again, and we appreciate the steps the company took to resolve the issue.

My story is a long one. Completely and undoubtedly screwed over by this company. Had a technician to my house on a Thursday morning for an emergency type situation, broken shower, NO water through my entire house. Technician didn't have parts said they'd send someone out the next day, early morning. Friday noon rolls around with the only info we received being your technician is running late. At 430 after many calls to checkup on our service we receive a call that our technician was broken down and wouldn't make it. Again this was 430 on a Friday so literally left us with no other choices and even had taken half the money as a down payment. Multiple calls to a buisness that advertises being open 24/7, clearly that arent! Not one call back about helping us navigate a situation they put us in, Monday morning comes I assume I will be a priority, and recieve a call bright and early but NO i had to call them! A man I spoke with apologized and said he would like to offer me a free service for my trouble and would contact me again the following day. NOPE. 2 weeks later and not a peep. So very very unhappy with this company and the customer service.

DO NOT USE!! Update to owner response: LIAR! You did not fix the leak at the shutoff valve and were paid in full. How did you know it was safe if the gas was OFF... FRAUD! please see attached proof of receipt and picture of gas leak, (see the bubbles). STOP PAYING FOR YOUR FAKE POSITIVE REVIEWS, ITS MISLEADING. THEY ARE ALL THE SAME, ALL THE REAL REVIEWS ARE NEGATIVE BECAUSE YOU ARE AWFUL COMPANY. You pay for 10 good reviews after you get 1 bad review. You can't even send people out on the same day, can't even shut off gas at the gas meter. When your part failed less than a month after installation, you failed to show up for 5 days when there was no heat and failed to honor your warranty. Also please respond to my lawyer! AVOID THIS COMPANY AT ALL COSTS.

DO NOT USE!!! I had an awful experience with Green Energy AC. Their technician broke a gas shutoff valve during a simple repair, was unable to shut off the gas at the meter, and left the property with an active gas leak. The fire department had to shut down gas and electricity to the entire building. I was told the job was completed even though it wasn’t, and I had to hire another company to fix the damage. The gas valve they installed later failed and was installed incorrectly, and despite the work being under warranty, they ignored multiple no‑heat calls for days. I ended up paying additional contractors to correct their mistakes. Based on safety issues, poor workmanship, and lack of communication, I cannot recommend this company.

Mohamed was extremely pleasant and helpful in servicing my Navien tankless hot water system. He explained everything to me in a very kind and polite fashion. Thank you!

I woke up to my heat not working. They were able to have a tech come immediately. Thanks Manuel. He figured out my heat exchanger was rusted out so my pressure switch wasn't registering correctly. I received several quotes to fix it but went with replacing the whole HVAC unit due to it being 20 years old. 2 days later, techs came to replace it. Thanks Eric & O'Neill. I didn't have the money to replace it but they have financing options. The entire experience with this company was excellent. Thank you so much for getting my heat working before the real cold weather starts. I highly recommend them.

Muhammad took an extraordinary amount of time diagnosing a problem that had safety implications. It was a long, hard process for him but he didn’t give up! Highly recommend him and green Energy.

The team sent Byron to examine our situation. Nearly 60 year old system in need of repair. They examined carefully and completely. Allowed us to ask innumerable questions, gettimg Lucas on the phone. Put together a replacement system package, and scheduled a next day installation. Fantastic.

Mohamed and Khalil, both here to address our gas line situation, were very respectful in our dealings and communications. They've left here just now, but I'm feeling pretty satisfied about our forthcoming visit and work to be done tomorrow.

Wow! What a truly great experience, I’ve had at least 5 different companies come to my home and assess my heating system but never have I had someone as thorough and friendly as Irvin. From start to finish, he made sure he would leave with a resolution. He and his whole team were very transparent, discussed options with me, and explored different solutions for my home. They definitely build a good relationship with their customers and we’ll definitely be calling them back for any future needs. Irvin built our trust and made the entire process really easy to understand. 10/10!

Extremely Unprofessional and Avoid at All Costs

Green Energy Mechanical has been one of the most frustrating companies I’ve ever dealt with. They were the original installers of the central AC in our home, so when the system failed, we contacted them to diagnose the issue. They identified several failed parts and quoted us for the labor to fix it, requiring a 50% deposit upfront. We paid — but the service never happened.

I had to call every single week just to get an update. Larry kept giving excuse after excuse and making promise after promise, but nothing ever moved forward. His repeated apologies meant nothing because what we needed was an actual solution, not months of empty words.

After getting nowhere, I requested a refund of the deposit and reached out to Chris, the tech who diagnosed our system. He told me the parts weren’t under warranty, even though they absolutely were. I provided proof, which he asked me to email — and then he simply ignored me. When I followed up by text, he claimed he needed to speak with his boss… and then the ghosting started again. Same story, no action.

This company refused to work with the manufacturer, ignored warranty information, took a deposit for work they never performed, and wasted months of our time with zero accountability. The lack of professionalism is unbelievable.

Save yourself the frustration — stay far away from Green Energy Mechanical and take your business elsewhere.

Khalil did an excellent diagnostic job. He was respectful and thorough in his planning. He was able to coordinate an repair as needed. Overall he would come highly rated.

Tony from Green Energy came by to do our heating system checkup, which they installed a year ago. He was very professional, thorough and a pleasure to deal with. He answered our questions and explained how our system was working in plain language. Very happy with the installation and service so far so I highly recommend Green Energy.

Heat went out on a cold day. They came with two techs that did not have any knowledge of how a system worked. They just kept talking to their boss all day on the “slack” line & taking pictures. After 5 hours of sitting around doing nothing. The boss called me and quoted an entirely new system replacement. Price range from 16k-32k. Had a friend come by for a second opinion the next day. He replaced a nozzle for $100 and my system works great. Don’t use this company. They are either incompetent or scammers.

My husband & I were having problems with our mini-splits & called Green Energy for repair & advice. The first day Byron, a technician came out & worked for hours trying to determine the issue. A second technician, Mohamed came out a few days later. Unfortunately, our outside unit is beyond repair. We made the decision to replace it & were assisted in person & on the telephone. We are very happy to leave an excellent review. The technicians, telephone personnel & management have gone above & beyond helping us. Thank you. Sincerely, The Miller's

Tom S from green energy mechanical gets my highest recommendation. Could not have been nicer or more efficient. Work was fast and well done. Great work on tub/shower ,bathroom sink and kitchen sink. Walked us thru work when complete. Removed all trash and old parts when complete. I think both areas might have been cleaner when he finished. If you chose to use green energy I would recommend requesting Tom

⭐️ 1 Star – Completely Unacceptable and Unprofessional

I had an appointment scheduled with Green Energy Mechanical HVAC after speaking with a representative who assured me they would come out first thing in the morning to take care of an urgent issue. They were unable to come the day prior, so this was already a rescheduled visit.

The technician arrived at the property and then told me he could not find parking and that if parking wasn’t available, the appointment would need to be canceled or rescheduled. I immediately called the office to explain the situation. I was told they could move the appointment to the following day — which makes no sense, as the snow would still be present and the same parking issue would exist.

I explained that I have two small children in the home, one of whom has autism, and that temperatures on two floors of my house were dropping toward 60 degrees while it was around 10 degrees outside. This is not a minor inconvenience — this is a winter emergency.

After placing me on hold to speak with a manager, the office called back and informed me that they were canceling the appointment entirely and would not be servicing me at all.

In the middle of winter, abandoning a family with young children and failing HVAC because of parking is beyond unacceptable. The lack of professionalism, accountability, and basic human consideration was shocking. This is by far the worst customer service experience I have ever had, and I would strongly caution anyone against relying on this company when it actually matters.

Irvin is the BEST! I cannot recommend Green Energy enough. From the moment Irvin arrived, he was friendly, professional, and knowledgeable. He took the time to thoroughly inspect our furnace, explain the issues in detail, and walk us through multiple options to address the problem.

The level of customer service truly exceeded my expectations. It’s rare to find someone who is professional, personable, and trustworthy all in one. Because of this experience, I have full confidence in both Irvin and Green Energy, and I look forward to continuing to work with them for all of our HVAC needs in the future.

I have been using Green Mechanical for over 10 years. The company’s technicians have always been great. Today Chelsea came to do the yearly service on the heating system. She was on time, efficient, went over details regarding the work being done and any work that I may need to consider in the future. Not only was she great at her job, she was a pleasure of a person. Another great experience with Green Energy Mechanical.
