Tips for Selecting a Whole House Fans

In its very essence a house fan consists of an electrical motor, fan blades and an housing to support the motor and the blades.

The better models have a better insulated housing (and door, and frames), a better and more silent electrical motor, and better and more balanced blades. The difference are usually in these details.

But there are some features you may also want to equate: traditional models versus recent models, multi-speed models, models with or without controls, new sealed and insulated models.

Tip 1: Buy an well insulated and sealed fan

Bet on a tight-sealing cover and on a sealed system (including a sealed door for the fan opening), namely if you want respond to weather changes in a handy way.

This features are also a guarantee of a much more silent model.

Tip 2: Choose a multi-speed model

Multi-speed whole house fans – usually two-speed fans – have significant advantages. They allow a wider flexibility to their homeowners: the high speed allows the entire house to be ventilated quickly, while the low (and quieter) speed provides an agreeable air circulation…

Tip 3: Control options

Pull-chains or wall control switches are common and handy. Many models allow you to run or shut off the whole fan, or set the fan speed with simple on/off wall or pull switches; some models involve also a timer to run or stop the fan at pre-selected times.

Tip 5: The big alternative: traditional vs modern whole house fan models…

Traditional models– either with fan blades attached directly to the motor (direct drive whole fan technology) or based on a pulley and belt system to operate the blades (the belt driven whole fan technology) - are tested, reliable and cheap… But they can be noisy and usually demand more complementary work and costs involving sealing and insulation...

New models are much more silent, sealed and easier to install (and demand less insulation work). But they are also much more expensive and less tested…
