Posted on Google Omied LeleTrustindex verifies that the original source of the review is Google. Pasha (technician) was very helpful. We had a clogged drain and were unable to clear it ourselves. He arrived and fixed the drain and was very clean and polite. Left everything as it was before he arrived. Highly recommend.Posted on Google Liang KatherineTrustindex verifies that the original source of the review is Google. Fantastic service! We really enjoyed working with United plumbingPosted on Google Natalia ShreveTrustindex verifies that the original source of the review is Google. Pasha was very professional he gave us a couple of options and finished the plumbing job very quicklyPosted on Google Just JaniceTrustindex verifies that the original source of the review is Google. As a busy homeowner I truly appreciate their ability to work around my schedule and needs. My garbage disposal recently died, and Neo was professional and offered my different options. He had the parts I needed and was able to complete the job quickly and cleanly.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I wholeheartedly recommend United HVAC, Plumbing & Electrical. I recently hired them to replace the original 1961 HVAC ductwork in my house, and they did a wonderful, extremely professional job. I am beyond satisfied with the results. You don't just have to take my word for it--I actually took pictures of their completed work, uploaded them to Google Gemini, and asked the AI to evaluate the installation. Even the AI praised their work, calling it a "top-tier, textbook installation"! (See the screenshots below). During the bidding process, I compared United with another company. United's quote was slightly higher, but choosing them was absolutely the best decision. Their program manager, Tim, was incredibly easy to work with. He quickly identified asbestos tape on my 1961 ducts and insisted we use a C-22 licensed abatement company to remove it safely and provide all the legal documentation for future reference. The other company offered a cheaper route by doing the removal themselves, but for something as dangerous as asbestos, doing it by the book is well worth the minor price difference. I also want to give a massive shoutout to Bair (Bayar) for his exceptional craftsmanship. He is easy-going, friendly, and really listened to all of my concerns. He provided great recommendations on how the new ductwork should be organized, and actually used a machine to fine-tune and balance the air pressure throughout the house. To top it all off, he even carefully reorganized the insulation in my attic after the work was done! It's this kind of attention to detail that makes them stand out. The pictures speak for themselves. If you want true professionals who care about safety, honesty, and quality craftsmanship, go with United HVAC.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I highly recommend United HVAC, Plumbing & Electrical! From start to finish, the entire process was incredibly smooth. They handled all the permits and inspections throughout the project, which gave us complete peace of mind. Every single technician we interacted with was friendly, approachable, and truly easy to work with. I specifically want to give a massive shoutout to Max (Aiusha) and Rinat for their wonderful work. Max is super professional and highly skilled. He installed my water heater and water softener with absolute "military precision." I'm the kind of guy who has a lot of weird, specific ideas about how pipes should be routed and extra gadgets I want installed to monitor the system, and Max handled all my requests with total ease. I am also super paranoid about plumbers plowing through studs or structural beams in my 1961 house, but Max was extremely careful and treated my home's structure with the utmost respect. Rinat is also a fantastic plumber. He installed a PRV, a Moen Flo auto-shutoff valve, an RO system, and even replaced some of the old sewage pipes in my house. He really listened to all of my requests and finished the job quickly and professionally. I highly recommend him! Because of their wonderful service, I’ve officially signed up for their company's membership. I am currently working with them to redo my HVAC ductwork, and I will definitely leave another review for that project once it's done. I'm sure they will do a wonderful job there, too!Posted on Google Ritesh BediaTrustindex verifies that the original source of the review is Google. Great service. Loved the professionalism and the way fixed my plumbing problem. I would call them again.Posted on Google Ginger PerngTrustindex verifies that the original source of the review is Google. We had to replace the wax ring on our toilet. Scheduling was easy; pricing was fair (much cheaper than the other quote we got!) Our technician, Melvin, was polite and expedient. This is our second time using United and highly recommend for gas and plumbing services.Posted on Google Joseph MartinTrustindex verifies that the original source of the review is Google. Melvin was great. Fast and efficient.
