Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Installing a ceiling fan where no wiring exists is a difficult and potentially dangerous job that should not be attempted as a DIY project. It is recommended to hire a certified electrician to build the necessary electrical infrastructure. In some areas, building codes require this work to be done by a professional to ensure safety and compliance. Due to the complexity, this type of installation is a significant job that could cost up to $2,000.

Stainless steel or aluminum fans are long-lasting and have less air resistance. They are best for outdoor use as their durability helps them withstand unpleasant weather conditions. Their heavy weight requires a stronger motor, which leads to more noise than other blade materials.

Wooden fan blades are a classic, durable option. They are much quieter than metal fans and feature a wide range of styles and finishes to choose from. However, they can be damaged by moisture if not covered with plastic.

Plastic fan blades are lightweight, easy to clean, and versatile. There are various shapes and styles to choose from as plastic is easily molded and dyed. They will also deteriorate slower than other materials as they aren’t as susceptible to humidity and moisture.

A typical fan installation takes between two and six hours. The exact timeframe can be influenced by factors such as the home's structure, existing electrical characteristics, ease of attic access, and whether complex wiring or additional attic ventilation work is required.
