Find out why you don't need to vacuum out your heating ducts unless you have done construction in the house. Instead, you should install a good quality electronic air cleaner on your system.
LESLIE: Rita in Illinois is calling in with an HVAC question. What can we do for you?
RITA: Yes, I was wondering how you feel about having someone vacuum out your hot and cold furnace vents.
TOM: Your heating ducts .
TOM: Yeah, we don’t really feel strongly about that. I think that what we do recommend is a good-quality electronic air cleaner  on your system. But unless you’re having construction done in the house, where you’ve generated a lot of an excessive amount of dust, I don’t really feel like duct cleaning is necessary.
RITA: OK. Alright. Well, thank you so much. My husband will be glad to hear that. (Leslie and Rita chuckle) Save us some money.
TOM: OK. Alright. Tell him he’s got some more money now to take you out to dinner. Thanks so much for calling us at 1-888-MONEY-PIT.
