Zach Was Excellent
This service was completed as part of the Service Contract Agreement we recently agreed to with Allen Services. The overall value of this agreement is yet to be determined. However, I thought our technician for this job (Zach) was excellent. He was professional, courteous, knowledgeable and, I think, fair and honest. I appreciated his straightforward approach.

AJ and the Team from Allen
After repeated power outages this winter, ordered installation of a Generac 26kW generator with connection to our propane feed. AJ and the team from Allen were a great group with whom to work. They got the install done despite snowy and cold weather. Would happily work with them again.
Robert Dannenberg
I will always use him
Jon is very honest and I screwed up and there was nothing wrong with our shower. He did not charge us, I will always use him and recommend him highly. My husband forgot to tip him, so I need to figure out how to get that to him. Thank you again for great service in such a chaotic world. Kristie Thomssen Bruntz.

Great service, reasonable price
Leaking disposer unit promptly replaced along with drain pipe cleaning. Great service, reasonable price. Thanks to Jon Harris!
Bill Jackson
Friendly, Efficient Service
Matthew Mish provided friendly, efficient service and explained what was needed before completing his work. We haven’t used plumbing services for quite some time, so I don’t know what the prevailing rate would be. Since we have an annual contract with Allen, we trust the cost is competitive and within normal plumbing pricing standards.
Janis Edwards

Mathew was professional, courteous, and explained everything in detail before starting his work and reported back after completing his drain clearing work.

Excellent Experience
20-year-old hot water heater started leaking. Gave Allen Service a call and someone was at my home within an hour. Everything was replaced and back working the same day. Easton provided several replacement options and did a great job. Excellent experience.

Jon was extremely knowledgeable and took such good care of us. He was friendly and open to questions and educated us well. Would use again.
Evan Ferg
He Was PHENOMENAL
Zack J. serviced our home today and he was PHENOMENAL. He was pleasant to talk with, very professional, and took the time to help educate us so that we had a better understanding of how we can be preventative with our systems. He had no issue walking us through and showing us what he found, and was great at taking before and after pictures. We will absolutely be requesting Zack J. for our future services, and he has made us feel more than solidified in our decision of continuing our membership. We not only feel like we have made a smart decision, but we truly feel cared for due to Zack J. Thanks again, Zack, for everything.
Britny Doole
We had a great visit with Vee
We were serviced by Vee and her “co-worker” Waco Flaco. Waco Flaco was a great listener. He sat quietly and never interrupted. Vee, on the other hand, oh my goodness, we couldn’t get her to be quiet! 😂 All this is in jest. We had a great visit with Vee. She did a very comprehensive inspection and gave a clear explanation of options for us. We chose to have the ducts cleaned and also install an IAQ system after seeing the pictures of our duct work. She is friendly, very professional, and the entire visit was great. We enjoyed meeting her and her “co-worker” and look forward to seeing her again when she installs the IAQ system.
Kathy Seele
