Customer Reviews

Fabio Hsu

Oscar was outstanding! He communicated clearly and professionally from start to finish, providing a thorough explanation of the issue with our leaking toilet and outlining the best solutions. With his positive attitude, high energy, and genuine customer-first approach, Oscar truly made the experience enjoyable. He didn’t just fix the immediate problem—he went above and beyond by proactively inspecting for potential future issues, helping prevent bigger headaches down the line. His attention to detail and commitment to quality work were impressive. I highly recommend United HVAC, Plumbing & Electrical, and specifically Oscar, to anyone needing reliable, top-notch service.

United HVAC & Plumbing’s technicians were professional and good communicators. They came when scheduled and diagnosed our plumbing issues quickly and thoroughly. The team worked quietly, quickly, and cleanly to replace a long kitchen drain and a leaking toilet. Both repairs are working well and are improvements in the previous conditions. (We have an old house and it has seen many fixes over the years.) I would definitely hire United HVAC and Plumbing again for any needed repairs!

We had a great experience with United. Teo from their team helped us with a new tankless water heater to replace an old one. The installation was done flawlessly. We later had some minor pipe issues, and they came to help us immediately even during the holidays. Thank you and really appreciate it!
