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…

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…

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!
Bella done a great job from the start to finish the job
Had a leaking water heater… United came out the same day and replaced it. They were very helpful and professional. I will definitely call them again for any plumbing needs.
I cannot say enough good things about these folks. I contacted a few companies via Yelp Project about replacing my water heater with an outdoor tankless along with removing a deprecated water softener pipe so I could remodel my garage. Their response time was the fastest, their quote ($) was the best, Bella's…
In this dark world of overpriced, unscrupulous plumbers, United Plumbing is a beacon of light. Not only do they genuinely care about fixing the issue at hand, but they go about the repair in an honest and trustworthy manner. Their prices are fair and the work is done right. I'm thankful to finally have a service…
Very professional service and nice people. The costs is reasonable. Strong recommendation.
Got a new tankless hot water heater installed by United Plumbing. They were honest, helpful and quick. Highly recommended.
Such prompt, courteous service. Called one day, water heater installed the next. I will certainly recommend this company to anyone who needs work.
Late to the appointment, but quick and efficient repair. No mess no drama.
All the United Plumbing people who helped me were very professional, courteous, and responsive to my requests. Their prices were competitive and reasonable. I would use them again for future jobs.
Our 75 gallon water heater stopped working yesterday with noticeable leaking from the tank. As it is 9 years old we decided to replace it with a new one. Contacted several plumbing services, united plumbing responded and scheduled an onsite evaluation quickly. The evaluation and the following new tank installation…
Technicians did a great job removing old water heater and installing the new one quickly and professionally. Highly recommend them for water heater replacement
Very friendly and reasonable customer services. The technician is also very friendly and professional. First time repair/replace water heater, and got satisfied results in the end. Would recommend and reuse for sure.
Very responsive. They followed up almost every day even though I was not ready. They are very knowledgeable telling me that the drip pan is not required for garage and it saves the owner some bucks. I appreciate the photos of the works taken because I was not there. Will use them again.
Their response was very prompt and the installer was very professional and sincere. The overall service is good.
Very quick response to my inquiry about a malfunctional water heater. Great follow through discussions on whether I should get a new heater or repair the bad one, what brand/type of heater I can choose, when the new heater could be installed, etc., even during off work hours. Thank you Oscar and Sam for helping me…
These folks did a great job with my water heater replacement. Service is quick and high quality. Price is very reasonable.
Called United Plumbing on a Sunday, and scheduled a Water Heater installation the next morning. The technician was on-time, and they did a wonderful job with the installation of the water heater in our garage.
Found them from Google. Called them. Had a good chat. Got a quote and they scheduled me for the date I asked. Technician came on time and installed the water heater, hauled away the old. Customer support followed up with Building department regarding permit signing and scheduling inspection. Everything moved really…
The pilot light on our water heater went out and wouldn't relight. Oscar was very upfront about the possibility of repair vs replacing the water heater. He was also extremely organized and very nice. He was able to get us taken care of same day with a new water heater, and he made sure we knew pricing upfront ahead…
