Recommended Customer Reviews

Enrique helped me out with replacing a very old water heater with a brand new Bradford White. Great service starting from when i called them to book an appointment until after the job was done.

There office communication was excellent, Guillermo was the technician and was super professional and his work was excellent.
Highly recommend A1 for any plumbing needs.

Tankless water heater went out on a busy Monday morning - no water pressure, no hot water. Service line picked up immediately and was able to schedule Christian to come out day of. He is personable, professional and knowledgeable. Troubleshooting with a descaler unfortunately did not work but Christian assured us he could get a new water heater installed next day. Took the time to compare models, hot water needs of the house, pros/cons of water conditioner/filter, and pricing. Install went perfectly, work area was clean, and we are very happy.

I highly recommend these guys! We had an issue with our plumbing at my business and they sent someone out with the hour I called. Robert and Jorge assessed the situation and thoroughly explained our problem and what needed to be done and was able to fix the problem. They worked fast as well and the price was great for the work they had to do!

Christian showed up to my house and he was polite and very knowledgeable about my issue. Great customer service. I would definitely recommend them.

Submitted request online for price quote. They said they would come out and give a free estimate. They were out that morning to give estimate. I had them do the requested work. Estaban was very nice and informative AND CLEAN. I know some plumbers are not so I found that important. They completed the work gave me some suggestions for work that might be needed in the future. I would 100% recommend A-1 Plumbing to anyone and will be using them when future needs arise.

I called on Sunday morning, and Christian was there before 12 PM. He quickly identified the issue and provided me with several options for fixing it. After I authorized the work, he and his coworker got started right away. The best part is that Christian was able to pivot during the fix and saved me $300

Excellent service Rudolfo was friendly and efficient he really did an excellent job

Osvaldo did a great job and went out of his way to try and save me $ good recommendations to avoid plumbing problems later on.

Very clean and professional. Introduced himself and his partner and asked what they can help with today. Listen to what happened and my concerns. Address the issue right away and checked under the house to see if there were any issues. Very knowledgeable. Told us about the 30 day warranty on the work. Had a great attitude and very friendly.
