From the moment they arrived, their professionalism, respect, and deep knowledge were clear. They quickly assessed and fixed the issues we were left with, and we only wish we had chosen them from the start. If you want the job done right the first time, we highly recommend UG Nasons. Outstanding service!

Out of several boiler companies/ plumbers I called (at least 8) Mike was the only one that…read moreresponded straight away and said he'd come out the same day, even though he wouldn't be able to get to us until late at night. He lives far and I was impressed that he was still willing to drive over and help us. Mike is a highly competent technician. He was able to diagnose the issue with our boiler and narrow it down to one of two possibilities. After ordering parts, he came back, as promised, to complete the job. We finally have a working boiler. Mike is a great and kind guy. He's honest, respectful, friendly and reliable. He won't let you down. I appreciate that he kept in touch when he was en route. We are grateful for all his help and wouldn't hesitate to re hire him.

Buying a mini-split system is an incredibly difficult process. The Mass Save rebate system is very…read moredifficult to navigate. I got quotes and presentations from 4 different vendors and the pitch and price was exactly the same - hour long presentation and a $30k cost. However, what each vendor tells you is that IF you qualify a $10k rebate is available and your net cost is $20k. Essentially the rebate is a scam - it just gives contractors the ability to inflate the prices and use the rebate to make the system sound cheaper than it really is. I finally met with McIver and he was able to simplify the entire process. He is not a Mass Save contractor. So he does not work the rebate, just offers a strait-up cost to install the system. When he gave me his quote, I quickly figured out that Dan McIver was an honest man and that the whole Mass Rebate program was a scam. His quote with the similar equipment and the same number of mini-splits was $13,500. I hired him for the job and they started within a week. One of my biggest concerns was esthetics - I was worried about too many refrigeration lines running around the outside of the house. Our house is a rental property in Cape Cod that had a lot of charm to it and we did not want to ruin the integrity of it. Dan came up with a brilliant solution and was able to run most of the lines through the basement to minimize the lines on the outside of the house - we were so pleased with this solution. His team did a fantastic job building out the system - they were clean and finished the project on the timeline he quoted. The work was high quality!! Net is that Dan took a very complicated buying process and made it simple and affordable. He is highly recommended for the quality of his work, pricing and his honest and straightforward approach!

We…read morecalled our HVAC service provider, who indicated the issue was not with the boiler, but with the propane gas valve. He went on to say that our boiler would need to be replaced fairly soon, showing me pictures of rust. He provided a quote for boiler replacement. I called two other HVAC companies, including Ocean State Air Solutions. Joe DeSilva and his very knowledgeable partner, Chris, came to my home to take a look at the boiler. Chris was patient in describing the functionality of the various components of our system. He went on to say that our boiler was a cast-iron boiler in good shape and should last for many more years. He said selling me a new one would be dishonest. These two gentlemen were honest, forthright, and patient with me, who has zero knowledge of boilers. So, I am cancelling my contract with my current HVAC service provider and going with Joe and Chris from Ocean State Air Systems because Trust matters to me.
