Excellent Installation

Quality product with an installation that had attention to detail with quality of material use, in some cases surpassing manufacturer's recommendation. Ivan did an great job, was friendly, and cleanup up afterwards.

Easy furnace installation

Ivan was timely and no disruptions, work done quickly. Good explanations of what was being done, and time required. Once installed, you wouldn't even know work had been done in the house. Heat on, no signs of the project.

Responsive, and quality work.

John Owens always responsive to calls for services related to heating/plumbing. Good communicators in the office and the field, Diana very helpful with scheduling and Randy explains exactly what is wrong and how to deal with it.

Great Service. Very reliable. Excellent pricing

John and his crew are great. They installed my "old" boiler / water heater 15 years ago. Alas, it went awry and they tried to fix it first. Even offered me a temporary water heater if needed. Awesome service. In the end we replaced the heater, they found one at a reasonable price and installed it quickly and efficiently. I would recommend them to anyone!

Great Service

I called the end of Monday; Randy was able to come out Tuesday afternoon, quickly diagnosed the problem, made the repair, and got my heater working again within an hour. Good work, fair price, excellent service.

In the best hands with John Owens Services

John & Randy really helped me out with my Rinnai on-demand hot water heater which had suffered an internal explosion after painters left it with the vents taped up with plastic wrap. John was very knowledgeable on the phone, & quickly sent Randy out to inspect & service it for a reasonable price. I felt I was in competent, trustworthy hands. Randy has every possible Rinnai part on his truck, & was a pleasure to work with. I am very grateful & will continue to use them to service my Rinnai.

Fast & professional

These guys fit our relatively small repair into their schedule when we were in a pinch. It was a repair to our water heater. Every other plumbing outfit said it couldn't be fixed. John Owens fixed it and saved us a couple thousand dollars.
