I performed an inspection for a buyer about 2 weeks ago. One of my comments in the report was that the AC condenser was emitting a humming noise when it was idle.
The seller has just commented that they had something called a Termidostat (don't know if spelling is correct) installed on the AC which they explained is a variable speed fan than runs when the AC is off to keep the humidity level in the house down. Now if that is the case, wouldn't you hear the noise from this fan running inside the house? What I heard was outside at the condenser and coming from the area of all of the electrical connections and the capacitor.
I've never heard of a Termidostat and how could it remove moisture from the air if the AC is not running?
Anyone ever heard of this?
