Best Heating Systems in Honolulu HI

Excellent job, Kama Hele! So pleased with all the work they did for us today. They went above and beyond to ensure our piping was repaired and not leaking. Highly recommended!

535 Plumbing are excellent. Extremely professional, organized and knowledgable. They are prompt, affordable and you can count on them to get the job done. Our brokerage uses them as our preferred vendor for all plumbing concerns. The staff are friendly and prompt with scheduling. We have used them for over 50 jobs and have never had a bad experience.

Requested a quote they never called back to do the job still waiting

Great mechanical contracting company. Staff is highly trained and do awesome work. Always get the job done on time & with a smile. No job is too large or small for this team of great employees.

Called for estimate of a toilet installation. They sent over a technician in an hour to give me an estimate. I asked if he could also replace my washer supply line valves. He gave me an estimate and told me they could do it all right then. Because of his professionalism and explanation of things, I decided to get it done then. Pleased with their work. It saved me time from having to schedule a future date for the work to be done.

I can’t believe the wonderful job NU Flow did for my plumbing. Great price! Even better service! I absolutely recommend and will be back in the future.

Thank you!

Over twenty years ago Larry installed a Tankless heater at my church that still runs efficiently today. Whenever I have had a plumbing challenge at my church or home, especially with water heaters, Larry has always been up to the task of getting it fixed right the first time. Not only that but he is consistently on time for all his appointments, he is honest and trustworthy and his pricing is fair and from what I have experienced quite lower than what others might quote you for a job. Before you pay thousands of dollars on a water heater system quote from the big plumbing companies, call Larry. He will give you a more realistic, fair, and reasonable price. Do yourself a favor and call Larry to install a tankless water heater at your place or to troubleshoot and fix a plumbing challenge. You will be glad you did.

They're my go to for plumbing issues.

Service was great but their invoice system is junk. They will send you an invoice 3 months after their service with no address to reply to and no phone numbers to contact them directly on Oahu. Once you do find their phone number online, no one ever answers in accounts and they don't call you back! Frustrating!

Dont ever call this unprofessinal company!!!! They dont show up on the time they tell you. They dont return your calls! Never never never call this company!!!!!!!! Trust me! You'll waste your money and time for this shity service! Find someone else BETTER!
