Late on an incredibly hot Sunday, my a/c decided to stop working. I called at least half a dozen places that advertise being available seven days a week. Some place never called me back or couldn't come out, one place was just rude, but Jack took the time to advise me on a few easy things I could look for so I could fix it myself without having to pay him to come out. When I found it was still not working, he came out the next afternoon, squeezing me in between appointments, and happily fixed the problem and showed me what to look for next time. He was pleasant to work with and so was Liz. Thanks for making this painless! I will definitely use you guys going forward.

Thank you!

We used AB/JDD plumbing to install a new furnace which was recommended by ab/jdd in our rental house about a year ago. We were assured that this unit will last for a long time (at lease10-15 years). Right after one year after the warranty period was over the unit failed. I called the company for help and first I was told they will service the unit the next day with a service charge but then later on the day I was told they won't be able to service it for two weeks from the day I called them. In the winter this was not acceptable and I had to look for someone else to fix the unit. I will not recommend this company as their work and service is not at all reliable.

Unlike products, its much harder to figure out when you are getting value for services you pay for. When you do find someone that you feel really did a good job and charged you fairly, it feels really good. Our experience with Jason at AB/JDD was just that. About one month ago, I had another plumber come out and look at the slow flow in the shower who said we needed a new valve. Then we looked up AB/JDD on Yelp. Jason came by to look at our showers and install a new faucet in the sink. Jason looked at the showers for 2 minutes, did not even need to open it. Said we needed a new shower head. I had one handy and he was right. No charge for that! Thats the value of experience. Then he installed our new faucet. Took a little longer than he had anticipated but he did not try to hurry and gave us his full attention. I liked that -- when he is working for you he is only working for you. He isn't trying to rush to the next job. He was on time for my appt, but if they are ever late, I will try and remember this. The whole job still got done within the hour as was promised. Cleaned up the work area before he left. Overall, experienced, competent, and takes the time to make it right the first time.

When I worked as a Building Inspector I looked at this companies work quite frequently. It was clean, code compliant and thorough. This company takes pride in their workmanship and that is why it is consistently exceptional.

This is the 2nd time I have used AB/JDD and they will be my first contact, EVERY TIME! The first time they helped me was to cover a home warranty issue which was handled without an issue. This time I needed a new water heater. Not only were they my first quote but they were also the cheapest. I called about 10 other shops and AB/JDD got me the LOWEST price for a larger water heater.

Everyone I was in contact with was helpful, friendly and knowledgeable. I had the work done within hours of the water heater breaking (yay for hot showers). With their help, I was able to get a rebate from PG&E (saving me more money). The techs swept the water heater closet and had it looking the best it has looked in years! Thank you for top notch customer service.

I can highly recommend AB/JDD Plumbing. Suddenly at 11:00 PM in the evening, my master bathroom toilet started backing up without stop, flooding the bathroom floor which thankfully was a step down from the master bedroom. Jack came within 15 minutes at 11:30 PM & stayed until almost 2:30 AM. He quickly opened up the sewer line beneath my home, & arranged for a decontamination service to come over at 1:30 am to clean up the mess in the bathroom and under the house. Because he was unable to use the snake to fix the problem, he came the next day with the heavy equipment needed, & after filming the reason for the blockage, his crew worked diligently to tear out the tree roots, and put in a new clean-out. He also went under the house to replace the affected ducts.

Jack & his crew were completely professional and more importantly, very quick to solve this disaster. Of even more importance, I did my homework & found out that their charges were lower than that of other plumbers. They were so honest & fair & really knew what they were doing. Without Jack's fast response, I would have had to demolition the entire bathroom, but even the sub-floor did not suffer any damage. I feel very lucky that I contacted him & have his phone number next to the phone just in case.

They do an excellent job with small plumbing issues. But for any large project they are not the company.
They did my copper pipping about five years ago. Today I'm in the middle of a remodel job and to my surprise a couple of the pipes that were to be replace were never changed out. They are outstanding in the plumbing business they respond in a timely matter and get the job done. But if you have a large project beware.

Excellent customer service. They were prompt and flexible with our schedule. They completed the job much quicker than we expected and it was very reasonably priced. Although I would consider the job we had them do kind of small, Jack and staff were very professional, pleasant and respectful.

This is the most heartfelt review that I have ever felt to leave in return for someon's selflessness and professional help. If my review leads you to earn the business of the owner of this company Jack, then my moral obligation will be fruitful. Here's my true experience hours ago from now.

We had been experiencing a loss of hot water since today morning and my wife and I decided to call in a 24 hour Hvac company. I searched for providers on yelp and picked this company after seeing some good reviews. Jack answered the call at 10 pm at night and offered to come down for help. The only thing for us was the cost associated which was about 100 some bucks. I had had a chance to talk to my relatives during the day abt our problem and she mentioned it could be a pilot light problem which is an easy self fix. We were just too scared to do it ourselves. So Jack offered his help and said he can come down in 30 mins. I hesitated a little bit as I was thinking abt the cost and kinda mumbled to him if this could be a self fix. That was it. Jack told me he would help me fix this with instructions on phone. His instructions and patience were so professional we fixed the problem in minutes ourselves.

Now I do want to mention that there's no such thing as a free lunch. I offered to pay him whatever he thought was due for his phone help. He didn't charge me anything. He didn't have to do that you know. And here's my way of saying thanks to him - to write him a good yelp review. Please let him earn your business.
