My entire experience with Allen Service was beyond expectation. We are buying a new home and had some concerns about HVAC and plumbing. Shannon was so very helpful in answering my questions and Daniel was able to get us in quickly because of deadlines due to home buying. I was amazed! Jeremy was our Tech and I can't sing his praises enough! He explained everything to me in a way that was easily understandable and showed me what he was talking about as he explained. He was also was ready, willing and able to answer all of my questions. I will definitely be using Allen Service for my future needs.

I'm not one to post many reviews or voice something publicly. But I will recommend this company 10 out of 10 to everyone. The owner is a man with heart and passion that loves even the little man, and their tech's work shows it. Kevin was my tech and was probably the nicest person I've ever had the pleasure of meeting. These guys are your guys for the job.

During one of their busiest times of the year, Allen Service fit me into their schedule and answered all of my questions regarding our furnace and air conditioning systems. They were on time for the appointment and Jeremy explained all of his findings from his evaluation in an easy to understand manner. It was great to work with a company that takes care of their customers so well!

Allen Service always provides excellent service and response times. Rich is an experienced technician who knows plumbing inside and out. Rich is very personable and as good at working with the customer as with the actual work. Everything was done as expected-job was well-done. Everything done correctly and clean up to the point where you couldn't tell they had been there. Highly recommended.
