"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

Customers say: Super punctual

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Aire Systems of Campbell and Saratoga truly sets the standard for exceptional service in the HVAC industry. Alton, the owner, went above and beyond to ensure I understood every aspect of the process, from selecting the right system for my small home to navigating available rebate programs. His expertise and dedication to customer satisfaction stood out as he guided me through the rebates step by step, emphasizing how beneficial they are despite the effort required. What really impressed me was Alton’s commitment to follow through—he’s not just selling systems, he’s supporting his customers well beyond installation. Daniel, the team lead installer, was equally remarkable. Always punctual and professional, he demonstrated a level of care that extended beyond the job itself. He kept me informed daily, explaining what was being done, what to expect next, and how long it would take. Knowing I had to leave for work, Daniel kindly spent time with my dogs, making sure they felt at ease while he worked. It’s rare to find a company that combines technical expertise with such personal care. Aire Systems, with Alton and Daniel at the helm, earns my highest recommendation!"

"My water heater was leaking and I needed it fixed asap because we had no hot water and I have small kids at home. Robert came, he saw the problem and fixed it fast and efficiently. He was professional and polite and the price was right. I will definitely call him again in the future. And have recommended him to family and friends. Thank you Drain Right Plumbing!!"

"Got a note from SFPUC for massive water use for the past several days, but no clear smoking gun. Was really worried and called Francisco asking for immediate help. He was at my house in 15 minutes and walked through all the most common culprits (toilets, etc), until we heard the water running outside and found that my kids had left the hose running. Paid him for his time and will definitely be calling him the future - amazing service. Kids learned a good lesson too."
