A Top Rated Plumbing & Heating Company

Serving Milford and all of New Haven and Fairfield Counties in Connecticut

James Onze Plumbing & Heating was opened in November of 1989. After having worked in the plumbing and heating trade for over eleven years, owner, Jim, set out with one truck and one scheduled job on the books. His reputation for top quality work spread quickly and continues to set the standard for our operation today. In December of 2000, Huckabee Plumbing Services a premier plumbing contractor, founded in 1965 by Henry Huckabee became part of our organization. While this addition expanded our customer base, our focus has remained on residential plumbing and heating needs. Over ninety percent of our work still comes from previous satisfied customers referring us to their family and friends. With thoughts of tomorrow we are undertaking a name change to Onze Southern Connecticut Plumbing & Heating better aligning our name with our primary service area.

Jim, along with his sons William, Jason and Brian working together in the business, guarantee our customers that a family member is involved with every aspect of their service.

I had to replace multiple burst baseboards in my home and Onze Plumbing did a fantastic job.After calling around for estimates, almost every company kept trying to upsell me services or gave me high ball estimates. Finally, a friend referred me to Onze. Jim, Jason, and the rest of the team were honest, friendly, responsive, and did a great job. I will be using them again for future plumbing needs.

Excellent service very professional and timely. The crew was very polite and meticulous in their installation. The company worked with us on timing to coordinate removal of scrap in as little time as possible.

Onze plumbing provides excellent service, going above and beyond in answering questions and responding to the various plumbing issues around our house. They were very knowledgeable, very helpful, and fixed all our problems without any issues at all. We highly recommend Onze and will be calling on them again.

We hired Onze Plumbing to install a gas line for our new fireplace and also to move our water lines for our washer and dryer. They were very prompt, polite and professional. I'd absolutely recommend them!

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.

Onze Plumbing & Heating does quality work. From meeting the owner Jim and how he explained the whole process from the removal of the oil tank, water heater and oil burner was very good. I also like the way his crew with the leadership of his son worked. Two of them showed up at 7:30am to start disconnecting the old heating system and a few hours later 2 more showed up to start removal from the basement and start the installation. It was pouring rain that day and they kept on top of cleaning up as they progressed. The last 2 guys showed up to install the exhaust and intake for the system. I was really impressed with how these guys worked as a team. They were finished in about 12 hours. Jim came back to go over the operation with me and show me how to increase the hot water. He also told me if I had any problems don't hesitate to call him directly. Overall I would give them a 10 for total customer satisfaction.

These guys are fantastic! James did a natural gas conversion for me and helped me renovate my kitchen and half bath this past year. Both times He and Sons were excellent to work with. Their work was clean, efficient and fairly priced.They were always friendly and easy to talk to and work with. I highly recommend their work for any level of construction or renovation.

I highly recommend James Onze Plumbing & Heating. Jim and his sons have now completed two majors projects for us, and conduct yearly maintenance on our new boiler system. For the first project, Jim installed a brand new, high efficiency, direct venting boiler system in our home when we purchased it. Most recently, Jim ran the plumbing for a new half bathroom that we added. In both cases, Jim and his sons are responsive, reliable, efficient, incredibly neat, and effective. The work they do is nothing short of beautiful (we often take guests down to the basement just to check out our new boiler). Perhaps best of all, whenever I have an issue, I can call or text Jim and he's immediately responsive. I don't think I've waited more than a day for someone to come by the house when we need something. And for the larger projects, not more than a week. Above all, everyone I've interacted with from the Onze business have conducted themselves with the highest standard of professionalism and integrity. Highly recommend!
