Client explained that there was an air restriction going into the bedroom in the basement. None of the unit had a clean out vent in the condensation drains.. Client signed a quote for the ionizer to be installed, but she wants it done after the contractor is finished doing the tiles work in the basement and in the upstairs part of the house also they will schedule ductwork cleaning before the ionizer get installed. This will be around a week or two from today.
