We keep going back to John Owens because the service is great, they are genuine, honest and perform the work at the highest level of professionalism. Plus the folks there are nice, which goes a long way with me 🙂 FYI, we have used John Owens Services for plumbing for decades to help along our 70 year old Eichler (!). Eichler owners will know that radiant floor issues and too narrow galvanized pipes plague these homes. JO knows just what to do.

My experience was great from start to finish. I got multiple bids and chose John Owens because of their fair pricing, their knowledge, and the way they treated me from the very beginning. Even the office staff was so helpful when it was time for me to sign contracts and set up appointments. They installed both a new furnace and water heater for us on the same day and it was seamless. Every John Owen’s employee I met was so professional, knowledgeable, and courteous. I will definitely use them again.

It is generally a good idea to get maintenance done on HVAC systems two times a year: once in the late spring before summer officially begins, and once sometime in the fall before winter officially begins. This way, you know you will have a fully functioning heater and air conditioner throughout the heating and cooling season.

  • Asthma or allergies inside your home.
  • Large accumulation of dust on surfaces.
  • Stale smells throughout your house.
  • Issues with humidity or development of mold and mildew.



Water heaters are complex devices with many different connections that have to be made, such as plumbing, gas or electrical lines, and more. Not only is it incredibly dangerous for you to attempt a water heater installation on your own, but it is also actually prohibited in certain areas. For an efficient and successful job, it is best to leave water heater installation to licensed and insured plumbing professionals.
