Frank was referred to me by my water heater manufacturer. When he arrived, he figured out the issue was not the water heater after all, and immediately determined the actual problem, which he quickly addressed.

Frank is one of the most trustworthy plumbers I have met. Reliable, on time and reasonably priced. He came over on Friday on a whims notice for a warranty service, had the parts in his truck and was able to get my hot water heater back in service within 30 min. During this time of uncertainty with the Coronavirus I am thankful for a trustworthy plumber to help me out. Thank you Frank!

Frank did an excellent job replacing my AO Smith water heater 6 years ago. Recently the control panel became defective, I was afraid no one would come out during the coronavirus pandemic. Frank came out within a few hours with the exact replacement part (still under warranty), got us back up and running again. Great service and a life saver! Highly recommend!

Issue wasn't resolved for the first visit (noise issue of AO Smith when burner is on) and when I tried to contact Alpha Omega again (more than three times, left voice mail each time), no one ever responded.
Now contacting SPS and hopefully they will be able to fix the issue

My water heater was broken for one day, called different company or handyman, either no reply, or no solution. I found the Alpha Omega Plumbing from AO smith service provider this morning, gave him a call, he answered phone, and came over to my house in a hour. Very fast response.
The service he did is very professional, he replaced the burner of water heater within half an hour, my hot water finally came back. Before he left, he also checked if there is gas leak or not after installation, very careful and professional. Also another important thing, the cost is reasonable!

Strong recommend his service!

Due to AO Smith water heater recall. AO Smith gave me Alpha Omega Plumbing number 408-622-8911. I called on 5/12/2019 left message, I send Text Message on 5/13/2019 1:39pm to followed up and followed up the message again on 6/16/2019. Frank never reply either text message or return my phone call. How can a business so busy can't reply to anything. If you're too busy just say it. You are not the only one plumber in Bay area.

I had to replace my tankless water heater up in the attic and install a new one. I contacted multiple plumbers and Frank's quote was the best! He showed up right on time and installed it in about 2 hours. I asked him to install a remote control so that we don't have to climb up the attic and he did that at the same price. He even brought in an electrician to make sure that everything is code compliance. Frank is a real professional and can be trusted 100%! Thank you Frank!

I am very happy to give Frank these 5 stars:
My AO Smith water heater was not working on Saturday evening (Mar 23, 2019). I called AOS's customer service in the morning of Sunday. After listening the issue I got, AOS's representative emailed the list of some service providers in my local (San Jose, CA). I called Alpha Omega Plumbing because it works on Sunday. Frank (owner) asked me my address, then he showed up in front of my house in 30 minutes later. Professionally, Frank recognized the issue of my heater: its burner's broken. A brand new burner was already in his truck for replacement. My heater was back to work after less than 30 minutes.
I paid nothing for labor and replaced part.
I am confident to recommend you to contact Frank of Alpha Omega Plumbing if you have any issue with the water heater.

Like some others here, I was given Alpha Omega Plumbing as the service provider to fix a water heater under an A.O. Smith recall. I called them 4 times over two weeks, left my contact information each time and I never received a call back.

I can understand being buried due to the recall. But in that case put on the voice mail that ""if one is calling due to the recent recall, we can no longer accept the work as we are backed up..."" It would have saved me weeks of waiting.

We are impressed by Frank and Mike professional work. I left a message to Frank about 1pm, thinking might need to call him again next morning, yet he reached out to me around 9pm and sorted out everything and come right next day. When he and Mike came today, they promptly fix broken water heater in 15 minutes. Very responsive, and efficiently. Highly recommend. We'll definitely call them next time.
