Jeffrey, Randy Weissbach of Cassidy air conditioning has inspected the livingroom air conditioner and air vents. The vent into the garden room cannot be easily be enlarged, it passes through a concrete wall, the vent into the lake room could be enlarged by approximatly 3 inches in height and maybe 3 inches in width. A new grille can be ordered which will take 4 weeks. There is no space for any sound reducing baffle in the duct, the air conditioning unit is tight to the back side of the wall. Randy does not believe tha enlarging the vent will substantially reduce the noise. He believes that a smaller unit would male less noise but suggested as a test that the grilles could be removed, in effect enlarging the free open grille area. Cassidy air conditioning has submitted a proposal to replace the existing air handling unit in the colset with a smaller, quieter unit for $ 5,245. This work would be done from the outside closet with out damaging the interior finishes. Doug EFTA_R1_01514482 EFTA02440503
