"Ok so this man Giovanni is a rare find. Read his reviews they are real reviews. I had a problem no hot water and we had a new tankless hot water heater put in 9 months ago. So did some research and as soon as I read Giovanniâ s reviews I stopped searching. The review of the son being concerned that Giovanni was going to take advantage of his older mother is the main review that sold me. So this is what happen, I called and spoke to Giovanni around noon. He was going to squeeze me in around 2:30. He had other appointments. So around 1:30 a friend can to my house and I told her about the hot water so she said let me see. She started going into settings and with a few clicks it started working. I then sent Giovanni a text telling him what took place. He called me I told him what my friend did and walked him through the steps. He said all was good except to take off always running and put on intelligent, which I did. So now the next day I get home from work turned on hot water and just warm after 5/6 minutes of running. So thinking there was still the problem I text Giovanni and ask if he could come and look at it either today or tomorrow told him about the warm water. He then text me back saying that the intelligent needs to relearn when we use water. He also told me to turn on hot water in few different places in the home. And yes he was right the water got hot very hot. It just needs to relearn when we use hot water. I have paid this man nothing, he talk me out of having him come to my house because he doesnâ t feel there is a need for him. He told me it could take a week to learn, and if I did have problems to call him back. WHAT A GREAT GUY. I kinda hope it does break just to meet this incredible man. THANK YOU GIOVANNI. Need to update this review because I did have him come to my house for a feew liitle things. He quoted my $1,595.00 for 3 didderent fixed. The reason why I am writing this is because after he started the work he realize that one of the issue I had didn't need as much work as he first thought. He removed $400.00 from my bill. He could have said nothing because the issue was in the craw space and I would have nevered known. That is a really great guy and an incredible plumber without a doubt. Would refer him to anyone and everyone!"

"Victor from L.A. Plumbing Pros came out Jan. 28 to start my water heater. He was here within a half hour of his call. He gave me a ball park price over the phone for doing the job but told me when he got here he did not realize I was within a couple of blocks of the Altadena fire. He said there is no charge. He was very gracious and kind and I am so grateful to him. He got the water heater to work in just a couple of minutes. Thanks again Victor."

"Very professional. Prompt. Tankless water heater has been working fine ever since. Hired another plumbing company before calling G M C. They were half the price. But did not solve the problem. David with G M C diagnosed the problem. Completed the work. No problems ever since. Thank you Angi, thank you David and G M C Plumbing."

"Giovanni reached out to me after I submitted a request through Home Advisor. My water heater started to leak after the recent earthquake that I needed to replace the whole new unit. I wanted a tankless water heater, but the cost and time frame did not workout for me since we needed it right away. I decided to go with the traditional water heater, same brand as the current one that came with the house and it was a trustable brand. Giovanni even checked our pressure valve which needed replacement as well. It took him the whole day to finish from purchasing the parts to installing everything. Once he was finished, he educated us and it was a done deal. He will be my go to plumber. Very honest, nice, and answers all questions."
