“Good morning, Greg
I would like to thank you so very much for the install of our home heat pump system. I cannot say enough how impressed I was by the professionalism, kindness, and tidy-ness of your team. Our house is a total disaster at the moment with several projects happening that make me so anxious and stressed. To be met with patience and cheeful attitudes during work hours and a neat house when I got home after a long day meant so much. I know our project was challenging, so a huge thanks to your team. And a huge thanks for making sure that when our kitchen counters went in we had someone to hook up our sink the same day. I know many people get by without a kitchen far longer thane we’ve had to do, but what a tremendous relief to have it all back in one day!
Thank you, again, for you all your help.”

12/07/20: Residential Boiler System Service:
“I wanted to share a text message that my sister sent concering the banging radiators at my mom’s house on Cottage Street: ‘Sean Casey rocks!!! He spent two days doggedly trying to fix the radiator in Mom’s bedroom that wouldn’t get hot and always banged like it was gonna blow up. He cleaned out the cruddy heating/boiler water and replaced the valve and insulated the pipes in the crawlspace under the room so the steam wouldn’t condense so fast, and voila! She now has heat, and no explosions. That guy is a genius. It’s been banging like that for 5 yrs… We need to drain some dirty water out of the system once a month or so to keep it running properly. He showed me how.’
Thank you!”

“Hey Greg,
I just walked in the door after a 3000 mile drive and everything looks FANTASTIC! I sent Dana a quick text, but please tell your entire team that they did a great job and the place is SPOTLESS! They did such a thorough job cleaning up after themselves, that I could not tell they had even been there, other than all the excellent new systems in place.
Your guys are awesome and they are to be commended for such a neat and organized installation. The only thing left (I believe) is an outside intake air vent which I will discuss with Dana tomorrow. Once he gives me the specs, I will have Kevin run the vent.
Again, many thanks Greg for all the great work you and your team have done to make my little home that much better.”
