"This couldn't have gone better. Chuck and Mike were pros and they did a beautiful job. They handled everything so well and even got it done ahead of schedule since our Airbnb we were staying at wasn't going to let us stay any longer. I had trouble installing some of the ceiling fans after they left so they even came back and installed those back on the ceiling at no charge. These are very trustable folks and I will hire them for any job down the road involving painting, popcorn ceilings, drywall, or related services."

Bathroom Fan Installation FAQs, answered by experts

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.

A blower and a fan serve different functions, so whether a blower versus a fan is better depends on what you need. If you need to heat or warm your home, it’s important that the HVAC blower is in good working condition. If you want to prevent an AC unit from overheating, make sure to keep up-to-date on condenser fan maintenance.

Ceiling fans are very often worth the investment because they improve comfort in your living space and help reduce utility bills. In the late spring and early fall—and even in the summer in some areas—homeowners with ceiling fans can often get away with open windows and fans, which can cut down on cooling bills and also reduce wear and tear on the HVAC system. Over time, ceiling fans can pay for themselves by saving you money on electric bills and air conditioner repair and maintenance.

If you think your fan needs to be oiled, the first thing that you have to do is cut the power to the fan. The best and safest way to do this is by flipping the circuit breaker that leads to that room.  Depending on the model of your fan, you may need to remove a cover. Look for a hole labeled oil. If there isn't one, check the manual or look for schematics online. Once located, use the recommended lubricant or spray. 

If your fan blades are spinning and there is no airflow, your blade pitch may be too flat, or your motor is failing. Adjusting the pitch is a simple DIY task if you have the tools. A failing motor is a bigger problem. You may need to replace your ceiling fan altogether. But fret not, we’ve got a guide for that!
