EXCELLENT Based on 233 reviews Posted on art hazenTrustindex 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.

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.

ThanksPosted on Gabrielle HoltTrustindex 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!
