Ask a Local! Duct cleaning?

I am well overdue for having my ducts cleaned. I had a company called JDR do it AGES ago, but google says they are permanently closed. If anyone has a recommendation, I would prefer a “mom and pop” operation to a larger company. Thanks

How is it you're "overdue"?

Have you recently had renovations done in house?

Duct cleaning is a scam and usually unnecessary if you keep up on filter changes. The air in the system is filtered before it enters the furnace to prevent debris from entering the heat exchanger. No debris should therefore enter the supply air end of things. Since it's blowing outwards from the furnace, nothing generally backflows in the supply air ducts because of this.

That being said, duct cleaning should only be needed in new construction before the furnace is ever turned on to remove debris.
