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!

Very happy with our service. The estimator went out of his way to provide the best solution and price. Work started when promised and our house was back to normal in a few hours. Workers were very polite and cleaned up the work area before they left.

Alton was our plumber. He was very professional and knowledgeable… keep in mind this was a Sunday afternoon… he responded quickly and efficiently expedited repairs. I would use the company again and recommend to friends and family… and you of course!!!

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.
