Pasha did a great job with installing my new water heater. Arrived on time. Professionally done. Clean and tidy. Good coverage for my floor during his work. Thank you Pasha and United!
I’ve used this company twice and had a great experience both times. Julian helped with a kitchen drain issue and did a thorough evaluation of the house, and Pasha helped with the water heater and faucet. Both were professional, responsible, and paid great attention to detail. I originally found them through their…
I had a great experience with Cristopher Villa. He came out to diagnose an error code on my tankless water heater and was able to identify the issue. During his inspection, he also noticed that the unit was leaking and brought the problem to my attention. Cristopher provided me with three different options to…
United responded quickly on weekend night and dispatched consultation next morning. Neo was very friendly and not a pushy salesman. Pasha installed the new tank and did a great job!
Pasha was exceptional, very patient and explained us everything. He diagnosed step by step the problem with our mixing valve and then fixed it. Thank you!
Recommended by other to contact them. Very professional. Answered all the questions, cleared all confusions and concerns right before install. The office responded quickly. The technician is efficient and polite. They clearly value their reputation. Will recommend anyone who needs a licensed permit work.
United HVAC did an excellent job when they installed my new water heater. Both Daniel E. and Atayde N. we're extremely nice, respected me and my home, and I could tell immediately that they knew what they were doing. After the installation they made sure that everything was working perfectly and that the area in my…
Our water heater suddenly started leaking. Gave United Plumbing a call and they sent someone to take care of it immediately. Special thanks to Neo and Pasha for their professional and tidy service and installation. Highly recommend!
Pasha was super quick to respond and his quote was accurate based on other companies we reached out to. Great work and would recommend.
Update: They finally have a technician come to my house and fix the issue. The technician is very professional and efficient while the management team is sloppy. —— I hired United HVAC & Plumbing in October 2024 to install a brand new 50-gallon American Standard water heater, for which I paid a premium price of…
Pasha did a great job replacing water heater. I had some questions about water heater installation and Lewis came out and explained everything to me and we passed inspection. Great job by the team from beginning to end.
Neo and Pasha were very helpful and prompt. they came immediately diagnosed our problem and fixed jt! very friendly and helpful
I had a fantastic experience with this plumbing company and highly recommend them. They were quick to schedule an appointment, which was a huge relief given the situation. The technician Neo initially came out to repair our water heater. They did a thorough job trying to get it up and running, but unfortunately, the…
Anton came to the house and helped fix the ignition issue. He was professional, patient, and very helpful throughout the process. I really appreciate his support and would highly recommend him.
The installer was professional, courteous, and did a neat installation of a new water heater and recirculation pump. There were a few issues after the initial installation: the water heater was not completely filled and put into service before the installer left, the reused drain valve leaked, and the AUTOADAPT…
The water heater replacement service provided by Gerardo and Teo was excellent. This was particularly impressive given the unit’s location in an uphill basement. They were very polite, highly skilled, and offered competitive pricing. I would strongly recommend their services to anyone requiring water heater…
Pasha and Neo did a great job replacing the hot water heater. When I called to make an appointment, they came the next day, provided a thorough assessment and walked through all of the different options. Neo gave us a good recommendation and Pasha installed the water heater quickly. Everyone was very knowledgeable…
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…
Great service. Altyn was exceptional in service and did a wonderful job, despite several unknown challenges in work. Highly recommend
United was quick to do an inspection and quote to replace our 20 year old tank water heater for a tankless and was able to start the job the same day. Professional and great service and the price was the lowest I received out of 3 or 4. Highly recommend!
