Whole House Fan Installation in Morris County, NJ

A whole house fan is different from an attic fan. It mounts in the ceiling of the top floor, usually in a hallway, and when a few windows are open at night it pulls that outside air through the living space and moves the hot air into the attic and out through the vents. In Northern NJ, where June and September nights often drop into the 60s, a whole house fan can replace the central air for a good part of the season.

Trapani Electric installs whole house fans for homeowners across Morris, Passaic, Essex, Bergen, and Union Counties. The job includes a dedicated circuit to the fan, a wall switch or timer within easy reach, a louver that closes tightly in winter, and a check that the attic has enough vent area to let the air out. We usually recommend ducted models, which hang from the rafters and are much quieter than the older direct-mount fans.

A whole house fan installation includes the following:

• A fan sized to the home's square footage, typically 2 to 3 air changes per minute for the top floor
• A dedicated 15 or 20 amp circuit from the panel
• A ducted or direct-mount unit, chosen for noise level and for the way the attic is framed
• An insulated, self-closing louver so that the ceiling opening does not leak heat in January
• A wall switch, timer, or remote, and a two-speed control where the fan supports one
• A check of the attic's net free vent area, and added vents if the attic cannot exhaust the air the fan moves

If your attic is short on venting, we will tell you before the fan is installed. A whole house fan with nowhere to push the air simply pressurizes the attic and forces dust back down into the house.
