    A O Dowd Plumbing Inc. did an amazing job with the water heaters I needed repaired. The team was friendly and professional all around. They communicated well from beginning to end - even followed up to make sure everything was working well … More after their service. They are truly reliable and trustworthy.
    I will definitely recommend this company to all my family and friends.

    As a small business owner, reliability and being punctual is a rare but precious quality that we seek in vendors and technicians. Needless to say, this year was extremely difficult for small business owners. So when LA County finally … More allowed our operations to resume we had very short turnaround time. This is when we discovered that our Boiler wasn't functioning properly. I called multiple vendors and specialists, but decided to go with Jason from A O Dowd Plumbing because of the way he went about asking me what the issue and problems I was experiencing in trying to diagnose the situation over the phone. Most other competitors were more interested in making sure you know their rates and how this is considered overtime. As a business owner, I am as skeptical and jaded as they come unfortunately due to the numerous times of let downs, price gauging, and simply dealing with "call centers" than actual technicians. So I took a chance with Jason. Although he had other jobs prior to ours; he understood the urgency of our situation and sympathetic to the fact that we're just a small business barely trying to hang on while LA County wreck havoc with abrupt opening/closing policies. He scheduled our job for the early evening since he knew we needed our boiler to be fixed in order to get opened. He did a great job communicating when he was about to head over outside of LA County and the time frame to expect him. Upon arrival, he diagnosed the situation and presented the potential solutions along with the price quote. I highly recommend Jason because not only was he very professional but he was very transparent in how he was going to present potential solutions in tackling the problem. He did wonders in getting our very old but still solid boiler up and running in a couple hours. He definitely saved the day for us.

    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.
  • Avatar Peter Kono ★★★★★ 4 months ago
    Great service. Helped repair/replace my water well pump. Highly recommended.
    Went out of their way to assist me. Hector is great!
  • Avatar Wendy Chou Le ★★★★★ 5 months ago
    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!!
  • Avatar Kendra Hudson ★★★★★ a month ago

    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!
