Hi, my name is Gary Harstad and I am President of GD Construction Inc. We have been doing kitchen and bath cabinet installations and Remodels in new and existing homes for over 25 years. In the process of tearing out the old and installing new cabinets, we almost always come upon heat vents that come up under cabinets. It's what we see in those heat ducts that prompted us into the duct cleaning service. The dust, dirt, sheetrock dust, insulation and yes, the unthinkable that we see in those ducts is not very pretty. It really is a dirty little secret in there, and if people knew, I am certain they would want to do something about it. We did a lot of research and found RamAir to be the safest and most effective duct cleaning system. With newer homes now using flex duct systems, I couldn't imagine any other way.
