Proper ventilation is important no matter what the season. Here are some ideas for how to improve your home’s air circulation and keep temperatures comfortable year round.

Whole-house fans are a wonderful investment. Imagine it’s the end of a hot summer day and the temperature has finally begun to cool outside. You could open your windows and then switch on your whole-house fan, typically installed in the attic, which would then quickly exhaust built-up heat in your home while simultaneously bringing in cool air from outside. Your house is almost instantly comfortable, and you didn’t even have to switch on the AC. For more, see Whole-House Fans Buying Guide.

Ceiling fans are another great way to get air moving. You might think just about using them in the summer to cool things off, but ceiling fans also can push warm air that has risen to the ceiling back down to the living area during the winter months. See the Ceiling Fan Buying Guide for more information about your options.

Good attic ventilation is essential. In summer, an improperly ventilated attic can trap heat and radiate it down to the rooms below, putting a strain on your air conditioner—and wallet. In the winter, heated air from the living spaces below can rise to the attic. If the attic is poorly ventilated, this heated, humid air can cause destructive condensation on insulation, joists, and rafters. Hot air trapped in the attic during winter can also cause snow to melt at the top of your roof and then refreeze at the cooler eaves, leading to ice buildup and, possibly, roof leaks. The solution for the problems of both seasons is to install attic vents that allow warm air to flow out and cooler air to be brought in.
