We recently hired United Plumbing to replace our old HVAC system. From start to finish, the experience was exceptional. Their technician, Oleg, thoroughly inspected our attic and crawl space to accurately assess our needs. The estimator, Fariza, provided a clear and competitive quote based on Steve's findings.

The installation team, Oleg and Valerii, were true professionals. They were courteous, efficient, and meticulous in their work. The quality of their installation was outstanding.

We were highly impressed with United Plumbing’s professionalism, responsiveness, and fair pricing. We would highly recommend them to anyone looking for a reliable and trustworthy HVAC company.

Victor showed up quicker than any other technician from any company could during a AC malfunction during a heat wave. He was thorough and fixed the main and secondary issues.  Great job.

Semenov was knowledgeable and straightforward with descaling my tankless water heater. Didn’t try to upcharge me. $130 cost for descaling, same as buying the tools. Good value.

United Plumbing responded quickly with a fair estimate for my garbage disposal replacement.  They were able to schedule for the next day and the work was done professionally and on time. Perfect!

Super fast to respond to my request and very easy to communicate with. Alex was prompt, professional and friendly and didn’t make me feel bad that I had a very simple job I probably could have figured out myself.

Great service. I’ll be back.

This was the 3rd company I looked into for my plumbing issues. I was able to get a same day appointment and the technician Almaz arrived at the start of the 2-hour window they quoted. I even got a text that he was on his way. I had two pipe leaks, one under the bathroom sink and one in the crawl space. Almaz was careful and thorough in diagnosing the latter and worked his way down the tight crawl area. We ended up cutting out dry wall in my garage to get an actual quote. Their prices seem very fair and so far I’m very happy I went with them. Will update once the fix is complete.

Excellent serviceman, Alex.  Company receptionist and online/ texting to keep me (client) updated every step of the way. I want that easy of a client because so had specific requests and they handled everything. 5 stars **** New sump pump installed under house.

Had some plumbing issues with backed up pipes. I contacted United Plumbing and was able to get a service update within 30 minutes on a Sunday which was amazing. Alex came out and took care of the issue at hand swiftly and efficiently.
