    The Pharmacist


    My home is 80 years old and was long overdue for an upgrade to its mechanics. I did my research and developed a basic idea for how I wanted to convert the home from oil to gas, upgrade the electric to a 200 amp panel and add central a/c. The gas company had at some point provided me with a list of approved contractors. I shopped around and if the contractor even showed up to the appointment there was always something that wasn't right, some were shady, most gave me prices that were 2x - 3x what they should have been and a few low balled the hell out of me but had in their proposal a clause for unforeseen charges which left it wide open for me to get hit with huge "extra costs". I was then referred to Onze Southern CT. I called and left a message, almost immediately Jim Onze called me back, this really caught my attention as every single other company took days to reply, and again if they even called back or showed up. I told Jim I knew exactly what I wanted and he stopped me and said how do you know. After a brief conversation he asked if he could come look at the project area and if it was ok with me he would like to show me three different options for the project. I agreed and we set an appointment. Jim Onze showed up on time for the appointment, not only that he showed up early throughout the entire project to ensure everything went smooth. Just as he said he would he provided me with three options that would fit what the home needed. He took the time to explain each and walk me through the benefits and advantages of each system. We agreed on what we would install and began to move forward with the gas company installing the line from the street. Jim provided me with advice and guidance the entire way, in fact he saved me over $1,000 with the gas company at one point. In searching for an electrician and an hvac company I experienced the same thing, they wouldn't show up, they seemed shady or were rip off artists. I told this to Jim and just how exasperated I was feeling with this and he offered two referrals to me, and as you would expect the electric and hvac companies that he turned me on to were of the same caliber as Onze Plumbing, offered advice, guidance and mapped out the perfect plan to complete the project. I now have a completed system installed that upgraded all the major points for heating and cooling in the home plus I can install a home generator and gas range in the kitchen with ease from pre planning the lines we ran. Onze is a family owned business, all of their employees were the most professional I have worked with on this or any home I have ever owned. The price was not the cheapest for this project but it was not the most expensive, this is the perfect example of you get what you pay for. The professionalism, advice, guidance and dedication to customer service is five stars. I appreciate everything Jim Onze, his son and employees did to complete this project to perfection. I recommend this company above any other.

    If I could give them more than 5 stars I would! I needed a new boiler in my home, and I contacted a number of different companies to figure out the best way to replace the old boiler. I spoke with small, medium and large sized firms and received a number of proposals. The Onze proposal was by far the best, not only in terms of price, but was also delivered very quickly and was well thought out. They then followed through and completed the job very efficiently and seamlessly as the new boiler meshed right in with my existing heating system. I was so impressed with their work that I am discussing doing additional work to my home’s plumbing and heating system with them. Overall, they exhibited excellent workmanship, fair pricing and pride in a job well done. I highly recommend them to others who are looking for high quality heating and plumbing work done to their home or business.

    We just moved into a new house that needed a lot of plumbing repairs done and Jason Onze did an amazing job in a short amount of time so that everything works perfectly. They also put in a new heating system in one day and it was seamless. We are happy to recommend Onze Plumbing and will call them for any future issues.
