We have an old house with hot water heat. About 3 years ago, we retrofitted the house with central air. Now we want a whole house humidifier and our AC company is saying they can install a humidifier in the attic with our AC unit and it would work because we run our fan 24/7 in the winter.
They said, it might mean we need to clean the vents more frequently, say every 3 years, they also said we'd need to insulate the unit in the attic to avoid freezing.
Does this seem feasible? We really need a whole house unit as the kids just hack in the dry heat during the winter.
