The product Build Time you see represented on this site is only a typical number of days the manufacturer states it needs to build the product(s) when ordered. Build times are based on business days (excludes weekends & holidays).
The build time does not include the time it will take to ship the order to you (the customer). If an order has multiple items and comes from multiple warehouses, you may receive part of your order on one day, and then receive the remaining part(s) of your order at a later date.
*Please be aware that seasonal demand of certain equipment may cause build times to run longer than what is typical.
THE "COMFORT COOLER" CA2421S SQUARE FOOTAGE RATING IS BASED ON A 3 TO 4 MINUTE AIR TURN OVER.
*To determine the proper size fan, multiply the square feet in your home by the ceiling height. Select the whole house fan which has equal or greater CFM performance as the calculated figure.
Triangle's whole house fans will lower your cooling bills by bringing in cool, fresh air and exhausting warm, stale air, making your home more comfortable. Moving air at 85° feels as cool as still air at 78°, so you can run your air conditioning unit less.
The existing soffits, gable louvers, turbine ventilators and ridge vents in your attic serve as outlets for the old hot air.
Fabricated from heavy steel with a baked powder-coat finish, these fans are durable and whisper quiet. Along with Triangle's automatic ceiling shutters, the Comfort Cooler or Comfort Aide is an easy-to-install, service-free unit.
