Josh took the time to explain the best options for our home and made sure we understood everything before moving forward. The installation went smoothly, and we felt confident knowing we were in good hands.

I highly recommend Addario’s Plumbing, Heating & Cooling and truly appreciate the excellent service from Josh and the team.“

“Choosing Oasis was a great decision I made. Their quote was best I had received, (one was almost $4000 more for the same equipment) Jeff was very responsive to any text/ calls within minutes. Jeff has a great team that works with him. Very Efficient and very Neat, you would not know they were even there. They ran Into a couple of issues with the way the old system was installed, but Jeff and crew took it all stride, and made everything right. It could have been a disaster. The difference was night and day. Jeff was very knowledgeable about all the equipment that was going to be used. He answered all of our questions, very thoroughly. Kudos to his team:Ian and Sam also. You will not be disappointed if you choose Oasis for all Heating And Air conditioning needs.

“John was fantastic !! I have never used him before but I like to look local and he was located the town over from mine . My whole house AC stopped working . I could go into many details but I’ll stick to the facts . I contacted John who of course is super busy this time of year in this heat . Even though he could not come out to look because he had so much work he walked me through somethings to try which I did . We then made contact several times after that as he checked in and gave me more advise . He then texted me the next day to see how everything was going . John was spot on with his assessment over the phone and my problem was resolved ! You do not find people like this anymore . He knew he wasn’t going to be able to help me because he was so booked yet he took the time out to walk me threw what to try and then at least 3 or 4 times made contact with me to see how everything was going all while knowing he wasn’t making any money or charging me . This is old school and just a fantastic and reputable person . He knows his business and he is not all about money and what he can get from people . The world needs more people like him and it would be a better place . I would highly recommend him ! I know he must be booked up like crazy because that’s what happens when you have a top notch business ! Thank you John for your help I truly appreciate it !“

“Our boiler suddenly died during a cold spell, so we were without heat and hot water. We were lucky to find David's Plumbing- they were very responsive to our emergency, The price for replacement was very good, considering that it also included replacing the very old water heater that could have gone at any time and been an extra expense down the road. They were very organized , completed the job in one day. and everyone, from the office to the workers that came to the home were very personable, helpful and professional.“
