Recommended Customer Reviews

Fast, really friendly, honest and affordable. We've done several projects with John Owens and they always exceed expectations!!!

6 months ago, John and his crew replaced the water heater, furnace and washer/dryer in our recently purchased home, including new piping and venting for all 3. His bid was competitive, short lead time, and their work quality was excellent. They finished on time and on budget and took care of all the permitting. We will definitely call them in future!

I have John to come and look at my heating system and water heater. he advise me and even I wanted to buy new one he said I do not need it. and he fixed everything for me. and saved me lots of money. he is the best. good to know there are some good company still out there.

lets talk about john providing service best in putting water heater had a problem call and find out yourself i have been in business over 30 year never come cross any body honest like him right on time right on budget

John Owens is a truly awesome heating contractor. John himself came to our house, and took a lot of time walking us through options for heating a cabin in the San Geronimo Valley. He helped us ask all the right questions so we could choose the solution that worked best for us, not something he was trying to sell.
It took a couple of meetings to decide on a direction. After we did, John set a date for installation and everything happened on time and for the price he quoted. I also liked that I saw a John Owens truck around Fairfax with a KPOO bumper sticker -- my favorite radio station.
You couldn't find a smarter, nicer and more organized heating contractor in Marin.
Highly recommended.

Reasonable, honest, knowledgeable and responsive. I highly recommend this company. Very pleased with all the work they've done.

Our old water heater needed to be replaced and we decided to go the intelligent route of tankless water heater. After seeking proposals from several plumbers recommended by a trusted hardware store in Fairfax, we chose John Owens Services for several reasons.
First, he is a Rinnai specialist and knows the tankless water heating systems very well. Second, his price was within reasons even though I could have save a few dollars buying the unit elsewhere or chosen another unknown plumber. The third and most important reason is the end result. John and his worker delivered and installed the heater on time and did a splendid installation job backed by a full extended warranty from Rinnai. Using modern technology and best quality pipes and fitting, the installation was a work of art in itself and strictly by the codes enforced by the town of Tiburon.
Anyone who would write a negative review about this company may have hidden reasons to do so and, like many others, I can attest of the superb quality and ethics of John and his crew. I think that I have found my new plumber for my future needs.

I got a quote for a Rinnai direct vent heater from John Owens. John told me that he would order it from Ferguson Plumbing supply in Corte Madera. John quoted me $2203 for the heater (Rinnai 8000 BTU direct vent model EX08) and $945 for the labor and materials install including a run of 45 feet of flex gas piping. Total quote was $3148.
I have used Ferguson myself in the property management business for years - so I sourced the heater (Rinnai 8000 BTU direct vent model EX08) directly from them for $1191.49 incl tax and shipping.
So I got the exact same heater for about half the quoted price. Then I called John Owens to find out why they had not returned my calls about installing what I had purchased. They told me they only install heaters and systems that they supply.
I feel that 100% mark-up is excessive, especially when the labor was already quoted. I understand contractors typically add 10% to 15% for disbursement on supplies. I did not like this attitude in the least because not everyone in Marin has money to burn. I think John Owens should have quoted a labor price that was fair to me and them - and let me have the freedom to save some money on the heater unit itself.

John Owens and his capable crew deserve at least ten stars.
I converted my little house in San Francisco away from a traditional hot water heater and into the 21st Century with an on-demand hot water unit, and replacement of a long dead wall heater with Rinnai products, and I couldn't possibly be happier with John's expert service and the Rinnai units.
I was able to easily make the appointment via email, and John arrived on time with his incredible knowledge and skills, and his jolly personality. We discussed various options for my house and after a thorough review of the existing heaters, the gas lines and the electricity box, John provided a complete estimate and that was the price upon installation. They even took away the old units for recycle/disposal, and left my house neat and tidy. They also take care of registering the units with Rinnai for warranty. Talk about service with a smile!
On installation day, John arrived early with his team, with all the tools and parts and whatever else they might need right there on hand in their well-stocked company trucks.
I really admire John's professionalism and prompt service, and I highly recommend him. It is obvious that he loves what he does, and I respect that he shares his knowledge by employing and training other people.
So here are TEN STARS FOR JOHN OWENS SERVICES!!

I was very disappointed at the lack of ""go-to"" attitude. I called this company because it was an authorized service provider for Rinnai. And, I thought as it was in Marin, it knew ""the lay of the land"". The first appointment was cancelled (by them) because it was raining very hard (which happens often in Marin in the Winter), and the owner was fearful of driving his 2T truck** up the hills of Mill Valley to get to my house. Strange, as trucks used by UPS, the garbage company, the recycle company, Golden State Lumber large flatbed trucks, Davey Tree trimming trucks with large chippers hitched behind, PGE repair trucks (with bucket rigs) and even a drilling rig have all been on this street, and all but the recycle trucks have been up my driveway, in addition to there being a large parking apron right off the street. So, we rescheduled for when it is not raining (today), and he didn't show up; his office admin (his wife) claims he tried to call me several times (nope; I've got call waiting), and that he drove by several times trying to find a place to park his truck. Well, obviously I've moved on, and found another service provider who understands that if they are providing services to Marin County, they need to know how to drive here. And, my advice is that unless your service location is on flat land, with access of at least a wide 2 lane street, don't bother calling him. **By way of comparison, an Ford F250 weighs 3T, and they are used by service and repair people all the time on my street , so maybe this guy just needs to move to Iowa!
