With the usual type of furnace, new filters should be installed each fall, and
depending on the situation, possibly mid heating season. Visually inspect
cold air returns, especially if floor grates, on frequent basis.

Subject : RE: Building air duct cleaning
Would any of you who work in an old(ish)building with hot air heat let me
know how often (if at all) the hot air ducts, cold air returns, furnaces (air
part) get cleaned? Also furnace filter replacement or cleaning?
Thank you ever so much, Miki - Townshend Treasurer
