    "Totally excellent service. My furnace was not working so I had no hot water. I called after 7 pm and Mike was there first thing in the morning to check it out. He located the problem and took immediate action to resolve it. Called suppliers, located the part for a 57 year old furnace. The following day Jason and Chase came and made the repair. Cost effective price with professional workmanship. Reliable and trustworthy."

    "Eric was awesome! Replied to my initial inquiry right away. He fixed my bathroom ceiling fan and replaced some outlets in my bathroom. He checked everything to make sure it was safe. Super friendly and I felt very comfortable. Very reasonable with pricing as well. I would highly recommend Angell Electric! Thank you"

    "Wonderful service from Adam! My water heater was struggling to keep up with my wife?s long showers - which by the way she heats them up hot as hell! ? Besides the point, Adam recommended sizing up the water heater in order to keep up with the demands of some crazy hot water. Incredibly fast installation process and Adam was really friendly. I would definitely recommend him to all my friends who are looking for a plumber. You should certainly give him a call!"

    "The people at ProActive Comfort were amazing from start to finish. They were responsive, thorough and professional and really saved us not just money, but our basement from what could have been a disaster by responding to us so quickly. Emily, who is their initial contact, responds quickly and is infinitely helpful . She responded to us almost immediately when we lost out hot water heater 10 days ago. They understand our need for a hot water heater and the price was very reasonable. They do all HVAC work and we will definitely hire them when it comes time to replace our gas boiler. I asked them for a quote on a direct/vent system and they sent it over in less than 24 hours . Anyone needing the services they provide would be wise to hire them ."

    "I couldnâ t have asked for a better experience. Losing your central air conditioning during a 10-day heat wave is miserable. As miserable as my problem was, within 72 hours of making contact with Next Gen, I had a brand new air conditioner installed. There was no hassle, no delays, everything promised & paid for was delivered. Dan from Next Gen was great to work with. I am a happy & satisfied customer. I will certainly call Next Gen for any future HVAC needs."
