Chris S. And Vern came last Thursday promptly in designated time frame. They took care to remove wet boots and lay cloths and clean up any debris ( had new hardwood in a room) and did a great job explaining the cleaning process showing me before and after pics. I’m sending EXTRA THANKS to Vern for noticing a meter that was off in the basement Radon mediation system. Considering we recently moved in, our home inspector said everything was working fine a couple months ago. Vern noticed the unusual meter reading even though they were here just to clean my ducts! I had a radon company come out today and replace a faulty fan. Our family is so grateful as I would not know how long I would take to notice it!
