Gave client estimate to replace her 20 year-old AC system. Currently there is a 4 ton there now, this is too big for the home. Home is only 1620 ft.² with all new windows and good insulation. There should be a 3 ton in-home. Gave client estimate for a 3 ton and a 4 ton unit. She needs to have a Rheem unit quoted for grant purposes. Hey baby.
