I have contacted this company for plumbing work (toilet, shower, etc) for a new addition on 1/20…read more I was referred to Tim, who was on a vacation at a time. I emailed him and he said he will come by once he is back. Emailed him couple of time after with no response. Finally on 2/5 I emailed him asking if he is still interested in the project, he said he can stop by today 2/10. When I emailed yesterday to confirm, he said he is not available for foreseable future and they are an HVAC company and don't do just plumbing installs. Very unprofessional and wasted a lot of my time.

There are three rental properties that fed off that same well. I was scared that our tenants would be hugely inconvenienced with lack of water for days. This was NOT the case at all.

He even went above and beyond by providing accurate documentation to help with the insurance claim. Thank you Cota & Cota!

John Kelly installed a unit in my Vermont home in 2014. He has been a tough man to get hold of…read morewhen needed, after the job is done. Sadly I needed him every year there after. The unit has needed one part or another every single year.. Aside from and in spite of annual upkeep, he has cost me additional money every single year. Now I have learned that the unit was vented improperly and had a significant effect on the fresh air circulation. Which in turn has cause soot build up on the unit. More money. I have tried numerous times to get in touch with John over the past year via email or voicemail. Unsuccessful in both areas. It is both sad and frustrating to put your trust in someone who claims to be a professional. Find someone else.

I was having all sorts of trouble getting anyone to call me back and schedule a date to come even look at it...until I called John. I called at 5pm in the evening, expecting to get a call back later that week. He called me at 6:30pm, and went to see the job within 2 days. The quote was very fair, and significantly below the one other person I had been able to get to look at the job. A week and a half later, we had a new furnace and new hot water heater, 2 days ahead of schedule. John communicated with me daily, let me know of anything unexpected, and was on time and on budget. Managing repairs from afar is always a challenge, but John made it easy with great communication, including pictures. He even checked in with me 2 weeks later to make sure everything was working correctly. I wouldn't hesitate to call John again. Truly a professional.
