"Robert expertly found the leak in the garage came from the air conditioner compressor, unit in back patio. The pipe ran all the way under the slab, I guess, through to the garage. We covered the area with a plastic tarp and stopped the water flow. What a relief!"

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

"Both the main and secondary condensate drains were clogged and the service technician cleared them. He also cleaned filters and verified proper operation of all equipment. We intend to use Carini for future annual checkups and needed service.

"Aztec H2O provided a high quality water softener and the install was impressive. Stephen, the owner was very meticulous and took his time to explain the function of the Pentair unit. Best of all, he was a fraction of the cost of other water systems like EcoWater, Culligan, and Life Source! Please call Stephen first!"

"Service request handled promptly. Installer was quick and efficient. However, we were not consulted on possible brand preferences. Comparing prices after the fact we found this plumber to be relatively expensive."

"I contacted Anderson Plumbing Heating & Air, a honest and trustworthy company after I realized at the last minute I needed a refrigerator water line assessment and they quickly sent Miguel to my home who noticed upon assessment inspection the water pressure was unsatisfactory and recommended replacing the water pressure valve in addition to the refrigerator water line. Miguel was absolutely amazing , a breath of fresh air, very easy to work with, and managed to accommodate my water line hookup needs fitting me into his busy schedule. Miguel provided me with a great service experience at very reasonable price! He went above and beyond providing before and after pictures of my old and new water setup, answers all of my questions, all while providing outstanding customer service with a smile & 10/10 quality of work! Thank you Miguel for a great refrigerator water line hook up experience !!"

"The technician came out to give free estimate and was on time but after a fairly brief examination of the leaking faucet gave us an estimate of $600 to repair the leak. Since this was quite a bit above our budget I decided to pull the cartridge out myself and look for a replacement. The tech was kind enough to point out where the shutoff for the water was located so that I could safely do this . When I opened the faucet up and removed the cartridge I took it down to Home Depot which has a nice selection of these items. Unfortunately they didn't have one like mine but when I looked at it more closely I could see that it was really only the rubber seal at one end that had been worn down. This was the source of the leak. I found a little package of these rings that fit my cartridge and this cost me a little less than $4. I installed a new one and put everything back together. It has worked just fine wiith no dripping for about 10 days now. I doubt if I could have done this all myself so I have to give credit where it is due to both the tech from Point Loma Electric and the person at Home Depot who also gave me some advice."
