Get matched with top generator install pros in North Billerica, MA

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

"STAY AWAY. Numerous issues and they will cost you more money without you knowing it. I just found out that I was on a **DO NOT SERVICE** list (after all the grief they have given me.) I am ticked off. Here is a summary due to the character limit: 1. They installed a faulty HTP tankless hybrid water heater. I argued with them for what I think was a good year before a HTP tech finally determined that I was right. Replaced it with a Rinnai RUR199in. 2. They took (stole) my oval ductwork and replaced it. I was fine with the replacement. I looked the other way but it was expensive and they never asked - they just hauled it away. Most homeowners probably do not realize how expensive and unusual that oval ductwork is. I could have even recycled it at a profit. 3. I recommended them to a neighbor only to find cops all over their home one day. Their plumber stole their special needs kids controlled medications after having them go into other rooms to turn on and off the faucets. I just chalked it up to a bad apple. 4. HUGE ROOKIE mistake. They short-cycled the new air handler. Vent was right next to the main return (2in. away.) Unecessary wear and tear, high electric and gas usage, and discomfort. Whatever was coming out was immediately suck back in. Unfortunately I did not realize this until a couple years later. 5. HUGE ROOKIE mistake. They never installed the 2-stage wiring. See directly above. Look it up. HUGE discrepancies in temperatures and sky high bills. Premature wear and tear. I wrote Freddy Jr. about this which might be the reason why I am on their list. But still, that is their job to get it right and not mine. Most people would have no clue for the life of their system. 6. They did not hook up the high-limit kill switch/float on the condensation pump which led to a flood and destroyed antiques. I hooked it up in less than 10 minutes. 7. I was told one day that the original manger was fired because he was skimming clients from the company. 8. There is no check valve on the recirculation line which they installed on the new tankless they replaced. I believe it is code and now I have to hire someone else ([business name removed]) to fix their screwup which likely killed my internal recirculation pump. Again, unecessary wear and tear along with high energy bills. I was willing to look the other way on so many things but the truth is they get away with this because most homeowners do not know any better. In other cases, I figured that no one is perfect and we all make mistakes. But then to find out that I was blacklisted a few years later because I called them out on their BS after I needed their help yesterday? The only thing I can think is that I ended up costing them more money on things they should have done properly in the first place. It is a company that needs better oversight and apparently has awful management. I am not bragging but I have an advanced engineeering background creating petroleum engineering training material for big oil (aka plumbing on steroids--makes this look like childs play), programming, developing systems for hydroponics, working with heat and waste recovery systems, fixing combustion engines, and building computers for over 20 years. My point is that I noticed a lot of things that most people would overlook because I know how many things work. I called them out and that is the only explanation as to why I could have been blacklisted. But do yourself a favor and go with [business name removed] or [business name removed] instead. It is not to say that others cannot screw up, but this is my experience with them and the straw that broke the camels back. Mention that you read this here and thank you. Perhaps the next company will not mess you up under the guise/protection of teamsters and protectionist unions that overcharge with ridiculous licensing requirements that ends up meani..."

"The electrical installation work was fast and the quality was good. Keep up the good work!"

"I can’t say enough good things about Bella's Electric Inc. and its incredible owner, Tiago Felisbino. From the moment you connect with this company, you feel the difference—integrity, dedication, and genuine care are at the heart of everything they do. Tiago is not only a skilled professional and a tireless worker, but also a deeply compassionate person whose values shine through in his business. His commitment to excellence is matched only by the love and pride he shows for his beautiful autistic daughter, whose presence adds a unique and inspiring spirit to the company’s story. Whether it’s a small job or a significant project, Bellas Electri delivers with precision, reliability, and heart. It’s rare to find a company that blends technical expertise with such personal warmth. Supporting Bella's Electric means supporting a family-driven business that genuinely cares about its community. Highly recommended—for the quality of the work, and the quality of the people behind it. "

"Chad worked with my husband and I on installation of a bathroom fan and we can’t recommend him highly enough! His expertise was highly valued- took the time to discuss pros and cons of the project and answer any and all questions we had. We also greatly appreciated his transparency (e.g. helped us to cut some of the labor costs if we were interested in doing some prep work ourselves) and communication (e.g. very timely and responsive with all texts, calls and scheduled visits). We were couldn’t be happier with the results and process! "
