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!

United Plumbing did an excellent job replacing our water heater and installing a flood-stop valve and pressure valve. Neo and Islam were very diligent, professional, and took the time to answer all our questions and concerns. They also offered one of the most cost-effective bids we received, without cutting corners. We’re very happy with the work and highly recommend hiring them.

A week ago, I posted a bathroom faucet replacement project, United HVAC was among the first to respond, the first to give me a fair price, and the easiest to work with. They followed up with appointment reminders. Alton is a great plumber, he came exactly in time, did a quick wonderful job installing the new faucet, tightened handles on another bathroom faucet by my request, was courteous and communicable. I received an email invoice, confirming my payment and explaining the (quite generous) warranty terms. I highly recommend United HVAC.

Not that I want to need a plumber, but when I do, it’s nice to know I can call United plumbing’s service personnel. Nice folks. They know what they are doing. Consistently good results. We had a water heater failure. United sent a technician to assess the water heater within a 2-hour window. Then they helped us schedule a same-day replacement installation. They also provided tips on how to help the new water heater last longer.
