Q: Some time ago I replaced the inexpensive fiberglass air filters in our forced-air heating system with more expensive pleated filters, which I thought would be more effective.
But the person who serviced my system said that the pleated filters add too much resistance to air flow through the ducts, making the system more expensive to operate. Is this true?

"Adding radiant-floor heat to a bathroom is probably the single best investment in comfort you could ever make," says TOH plumbing and heating expert Richard Trethewey. "Especially when you consider that you're going to be in there most of the time without any clothes on."
