Hes an honest man and would recommend him for any plumbing issues!

Our old AC struggled all summer. By the Book recommended a perfect replacement. Installation was smooth, cleanup impeccable. Now our home is an oasis. Five stars isn’t enough!!!

Here, we had a rare rainy week when the sump pump broke. By the Book made sure our basement remained dry, inspected the drainage, and promptly restored it. We avoided expensive water damage thanks to their quick response.

A unexplained leak in our pool's plumbing caused water to drain every day. These guys identified the problem, fixed it, and made the pump system more efficient. The water bill has returned to normal, yet our pool continues to be full. Outstanding work!

During a routine HVAC maintenance check, they spotted a cracked vent that could’ve led to carbon monoxide issues. They repaired it immediately and cleaned the entire system. Proactive care like this is priceless.

Installed a new water heater last week, and the difference is incredible. The technician walked me through the options, helped choose an energy-efficient model, and completed the job in one afternoon. No upselling—just straightforward, quality work.

Discovered a hidden water leak under our sink that was causing mold. They handled the leak detection and repair swiftly, then advised on preventing future issues. Their attention to detail and friendly approach made a stressful situation manageable.

Our AC stopped working during the heatwave, and these folks came through same day. They fixed the refrigerant leak, replaced the filter, and cleaned the vents. The system now runs quieter and cooler. Highly recommend their HVAC repair services to anyone in San Diego.

These guys were very professional and fast. I would definitely recommend them to any family or friends.

Leon was in the plumbing aisle at Home Depot and looked like he knew what he was doing there. I clearly did not! After waiting for two Home Depot associates to be called and not to show up, I asked him for help with finding a part. He took the time to walk me through and explain the part that I needed and why. I just wanted to commend you on hiring such a thoughtful professional man in your company. He was very professional and very knowledgeable and very thorough. He also promoted your company if I couldn’t figure out what was going on in our situation, which I appreciated. Thank you for taking your time to help. Be blessed as you are a blessing.

Stan Smith was the serviceman that saw to our issue. Truly a nice person with the best of social skills. Friendly and gracious. Beyond the personal aspects of Stan however, his work was methodical and he took care to explain it along the way.

It seems hard these days to find a company who deserves loyalty, but I’m pretty comfortable keeping these guys at the top of my list.
