What size fan do you need?

• <div><p>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 <a href="https://www.angi.com/articles/does-your-home-need-more-attic-ventilation.htm">the size of attic fan you need</a> 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.</p></div>

What size fan should I get?

• <div><p>The square footage of your room will dictate the correct ceiling fan blade size. For example: </p><ul><li><p>Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.</p></li><li><p>Rooms up to 175 square feet require 42- to 48-inch fans.</p></li><li><p>Rooms up to 350 square feet require 52- to 56-inch fans.</p></li><li><p>Expansive spaces over 350 square feet need a fan larger than 60 inches.</p></li></ul><p></p></div>

Q: Where is the backdraft damper located?

• <div><p>You&rsquo;ll find the backdraft damper near the top of the range hood (where it connects to the ductwork). However, some range hoods also have a second damper, which is located close to the roof or exterior wall where the ductwork ends. If you don&rsquo;t see a damper in either of these places, you might not have one.</p></div>

Q: Can I install an exhaust fan myself?

• <div><p>DIY is possible for basic replacements. Professional installation ensures proper wiring and venting.</p></div>

Q: How often should I replace a bathroom vent?

• <div><p>Bathroom vents' expected life span is about 10 years, but it can be even less without proper care and regular maintenance. Dust and debris, such as hair trimmings and excess moisture, are more likely to build up in vents installed in such spaces, which is why it&rsquo;s so important to clean them every six months.</p></div>

Jon, Ler and Emanuel L were the crew who installed 5 piers on the corner of my house. They were very efficient, and left things looking exactly as before they did the job. I received updates as their work progressed.
