Denson did some warranty work which did not fix the problem. Owner stated multiple times over the course of the last 2 years that the unit would be replaced only to find out that that was being said to sweep the problem under the rug. I had to call a reliable Trane company in another town to get decent service. 100% would not recommend this company to someone looking for a trustworthy business to service their purchase.

Rick Boren (owner of Den Son) was great at choosing the correct system that fit our needs. The installation team of four installers was led by Keith and was extremely experienced and worked well together.

My garbage disposal failed so I called Puskar Plumbing to have a new sink and disposal installed…read more I purchased the materials at Home Depot. Employee Tim Davis arrived on the appointed date and got to work. He ran into some problems because the new sink was deeper than the old one. He had to cut out part of the adjacent drawers to get it to fit. He deftly cut out just what was needed and I am still able to use those drawers (we thought we going to lose them). Overall, Tim did a great job, going so far as to prop up a sagging part of the counter top in the area behind the sink (an existing issue). Thanks Tim for the great work!
