EXCELLENT Based on 233 reviews art hazen2025-01-13Trustindex verifies that the original source of the review is Google. I sent out a request for a quote for a failing ejector pump. I got a call back almost immediately from U.S. Allied. They set up an appt for Monday with Howard. Service was prompt and diagnosed the problem as a failing check valve. Howard replaced only the check valve and the system was working great. Howard was great to work with and got the job completed very timely and was super clean. Appreciate all his hard work!!

Had a water heater with power vent and a thermo expansion tank installed. The office staff was very professional and courteous. Plumber Matt performed the install and also was very professional with great quality of work. I quoted about 10 plumbers and they were the best overall quote with an added bonus of exceptional service.

Steven Zink2024-06-18Trustindex verifies that the original source of the review is Google. Alex did an excellent job! Positioned the new water heater so that the controls would be accessible, added vertical run in the vent line for improved draft, added an expansion tank, explained very clearly what routine maintenance is recommended. Looking forward to the next project with US Allied! Liz Hornbeck2024-06-07Trustindex verifies that the original source of the review is Google.

Thanks Gabrielle Holt2024-05-24Trustindex verifies that the original source of the review is Google. Alex G. was such a great technician! He arrived on time as the dispatcher stated. I told him my issue, he provided me few recommendations to prevent service calls in near future and he got the job done at reasonable price!! He was very professional, he didn't come off as a " I'm trying to sell you something guy". Just a very genuine guy who worked with a purpose, to make sure the job was done accurately but with quality behind it! Nice to see this company is close to home too! I will definitely use them again in future!
