    I had some issues with my boiler and their website was very clear on their expertise in that boiler so I called right away. They were were a little outside my area so Jason spent 15-20 minutes over the phone walking me though how to diagnose … More and fix it myself. I was able to get it up and running. I’m impressed with his knowledge of the boiler and personal skills to communicate everything very well, not to mention going out of his way just to help. Very personable and easy to work with. Highly recommend.

    We had problems with our water pressure and valve. Jason and his assistant came out and very quickly repaired our system and valve. He was very professional, and the service was excellent. We would highly recommend his company.

    Our water pressure regulator broke just past dinner time, we had to turn the water off so the super-pressurized water doesn’t run and damage our pipes and stuff. Jason responded that night and was able to get everything fixed by lunch … More time on the next day.
    What stands out with Jason, besides being responsive and professional, is his ability to communicate. He’s really good at educating us about the issue briefly and clearly, and providing options so we can make decisions confidently.
    We used to use our handyman and sometimes YouTube for plumbing related issues. Now we have the go-to guy we won’t be making uninformed decisions anymore!!

    I would like to recommend A O DOWD to everybody that reads this review.
    I moved to this area two years ago, and it was my first time calling a plumber, being very careful , I had four companies come and gave me quotes on descale my tankless
    … More water heater, and a whole house water filter system. Out of the four plumbers I met, Jason stand out.
    First, he is quick to response and on time. Second, he is very professional, and very patient to explain everything that needs to be done. So after the first appointment, I can almost envision what needs to be done. Third and the most important thing is that I have a great deal. I have a tight budget, and Jason is so kind to provide the service and meet me on my budget. Forth, the service is excellent, I would give a ten star if it is available. Jason installed the whole house water filter system the next day I approve the proposal. He did a great job, very detail oriented. He even walked extra miles to fix the cracks on the wall around the pipes just to make me a happy customer!
    There are many experienced plumbers, but not everyone is patient with you; there are also many plumbers that can fix your problems, but not everyone has a heart to bring a big smile on your face by walking an extra mile like Jason!
