Whole house fan functioning properly. Found that eave vents have been covered with insulation. Another company blew in insulation and it is super high all the way to roof edge. Customer is saying the whole house fan takes all night to cool down. May be due to vents being covered. Worked fine before they blew insulation in. Insulation is about 2-3’ deep. Need to remove around vents and order new timer for whole house fan.
