CPI Service

I had 2 plumbing repairs. Replacing water connectors to the washer and replacing shower cartridge. It took 2 visits; one for estimate and one for the repair. Both visits took about one hour. I called on Thursday and was able to get an appointment at 11 am and repair was completed on Monday. Both service reps were courteous and prompt. Text messages to confirm appointment and estimated time of arrival worked well.

Danny Harn - doesn't get any better in terms of expertise and customer service. We had 5 water heaters that needed upgrading - his attention to detail is what made a huge impression and basically did whatever was needed to do an expert job. Thank you Danny for looking after our biggest ticket items - water heaters.

Bunhak is very professional and respectful to my Alzheimer mother when working for fixing both my heating system and my AC. He even went out of his way help me with my door bell for free. I'm extremely happy about his service. Now we can live through the cold winter system with a working heating system. Thank you, Bunhak very much!

Thanks to CPI plumbing I was able to get my kitchen sink drain unclogged and a new garbage disposal installed as well as they replaced all the pipes under my sink. Special thanks to Charlie who spent the day making sure everything was up and running. Shamir was really helpful and so was Gerardo!

Our new Heat Pump system has just been installed and we are very pleased with CPI and the new equipment. We are especially grateful for the knowledgeable and hard working technician Bunhak, who worked throughout our recent heatwave wave to finish the job. We would highly recommend the company CPI for any HVAC installation or maintenance.

CPI Service did a great job installing a new heat pump in my attic March '25. Enjoying the air conditioning. Will highly recommend.

Gerardo and Shamir came to my place today - when they said they would -and listened patiently to my explanation of what's going on with my water leak. They checked the sprinkler system, the meter, the main shutoff and gave good, understandable advice about steps to correct the leak issue. I appreciate the time they spent doing this with me.

Great experience. I worked with them for sewer line repair service. Professional team, Bunhak was friendly and experienced too. I recommend them for emergency plumbing services around San Jose area.

I had a great experience with CPI. Unlike many other plumbing services, they charge a fixed price for fixing the problem — no surprise hourly charges. From the start, they were clear and transparent about the total cost, which gave me peace of mind. Most importantly, they were committed to actually solving the issue, not just diagnosing it. The plumber stayed until the job was done right, without rushing or trying to upsell unnecessary services. It's refreshing to work with a company that values quality and customer trust. Highly recommend CPI Plumbing for anyone looking for reliable and honest service.

We got a new water heater installed by CPI. Shamir came in to give the quote and explained our options and the process. Sam the plumber came in the next day and took care of the heater installation and bringing it up to latest code. Excellent work. Reasonable prices. Highly recommended!
