Ventilation fans are different than normal ceiling fans.

Ventilation fans’ job is to remove offending air from the house to the outdoors. It is non discriminatory. In other words, it doesn’t care if the air on the inside is warmer than outside.

Usually, you’ll find ventilation fans in kitchens on hoods, in bathrooms, utility rooms, or in attics.

If you have a good reason to use these fans, then by all means use them. They are there for a reason. But don’t forget to turn them off when they’ve done their job.

A ventilation fan can suck the heated air from a normal sized house in a little over an hour. Again, in the winter this can be absolutely devastating. Your furnace will be overworked.

It’s the equivalent of leaving a window open for an hour or more!
