Whole house fans can provide effective natural cooling for a fraction of the energy cost of air conditioning. Drawing cool fresh air in through open windows and exhausting hot stale air out through the roof vents, whole house fans create a comfortable, natural living environment while they draw heat out of the structure to reduce air conditioning load for the next day. In dry desert climates, a whole house fan is a no-brainer - it can eliminate the need for air conditioning completely. What many people don’t realize however, is that even in most other areas of the US, you can use it in conjunction with your A/C to dramatically reduce your energy consumption. Typically, a whole house fan uses just 1/10th the energy of A/C. Plus, you enjoy natural fresh air in your home rather than recycled indoor air. While traditional whole house fan designs tended to be difficult to install, noisy and not suitable for most climates, AirScape whole house fans use a completely different design philosophy: they’re more efficient, quieter and easier to install than older designs, making this natural and efficient cooling strategy a great "new" option.
A whole house fan is effective whenever the outside temperature is lower than the indoor temperature - typically in the evenings and at night. A whole house fan mounts between your living space and the attic, drawing cool outside air in through open doors and windows while forcing the hottest indoor air into the attic and out through existing roof vents. This cycle quickly creates a fresh, comfortable indoor environment, and, importantly, steadily draws heat out of the structure itself, so you start the next day with a cool house, delaying or eliminating A/C use. The net result is you enjoy fresh evening air in your home, a wonderfully cool sleeping environment and save a bundle on energy costs.
