Action 1: Strategy the bath exhaust fan replacement

A brand-new generation of effective and peaceful exhaust fans is now offered in the house centers and from heating, ventilation and cooling providers. The brand-new fans are practically quiet. They’re likewise a lot more effective and utilize less energy than the older designs. They can even be left on full-time if you require constant ventilation. (A lot of common fan motors would stress out.) See “Searching For a Peaceful Fan,” listed below, for more information.

In this short article, we’ll reveal you how to get rid of an old bath fan and set up a brand-new peaceful one. For the most part you can do an exhaust fan replacement in less than a day with little or no ceiling repair work. While we’re at it, we’ll reveal you how to change normal 3-in. uninsulated duct with much exceptional 4-in. insulated ductwork.

This task includes electrical circuitry, so call your regional electrical inspector to discover if you require a license.

Setting up a fan needs just primary woodworking and electrical abilities. You’ll require fundamental hand tools, a power drill and a jigsaw. The fundamental operations consist of hand sawing a little drywall opening, driving sheet metal screws into aluminum ductwork, cutting aluminum duct, getting on the roofing and sawing a bigger roofing vent opening, and detaching and reconnecting electrical wires. If you face issues you can’t deal with, such as complex electrical circuitry, tight duct clearances, water damage at the roofing vent cap or a high roofing pitch, do not think twice to call a certified electrical contractor.

You’ll need to go into your attic and stroll on your roofing, so play it safe. Use a long-sleeve t-shirt, long trousers, boots, a hat and a dust mask to secure yourself from dust and insulation in the attic. While on the roofing, usage roofing brackets, roofing cleats or a safety belt for safe footing and fall security. And if your roofing is too high or you do not feel great up there, employ a pro for this part. The bath fan we’re changing is relatively normal. It lies in a ceiling with an available incomplete attic above.

The fan is effectively wired and ducted with 3-in. uninsulated ductwork to the roofing. If your old fan system has extra functions like a light or heating unit that runs off a 2nd switch, your electrical circuitry will be more intricate. If the rewiring puzzles you, speak with a certified electrical contractor to exercise the information. If you have a 2nd flooring above the fan, determine the height of the area offered. The brand-new, quieter fans are taller than the old ones, a minimum of 7-1/2 in. high. While it must suit normal flooring joist area, examine the fan measurements to make certain.

If you do not have an attic above, as we reveal, you’ll need to do the whole setup from listed below. This indicates you’ll need to cut open the ceiling a bit (and spot it later on!) to get the fan in and run ductwork to a wall vent cap. The connections will be the very same as we display in the image series. Nevertheless, altering to a bigger wall vent cap can be more intricate if you have brick, stucco or vinyl siding instead of wood. If you’re uncertain how to continue, consult a siding professional for suggestions.
