We will be installing a used 3.5 ton Goodman ac and coil. Model GSX16. This also includes a filter rack under the existing furnace with a condenser pad and service disconnect. Also included will be a a filter dryer to filter contaminants switching from r22 to r410a. We will use rx11 flush kit to clean all the old Freon out so that we can use the new r410a Freon. Evaporator coil will have an emergency drain sensor to protect against flooding
