"My air conditioner was not working so I contacted my home warranty service and they sent a local company representative to checkout the problem. It was a capacitor - the technician installed the part and it has been working ever since."

Bathroom Fan Installation questions, 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.

It is unlikely that a ceiling fan will fall, even if it develops a wobble. During a proper installation, ceiling fans are securely bolted to a ceiling joist, and the fasteners used for mounting are generally separate from the components related to balancing. A wobble is typically caused by an imbalance, which can be annoying and may lead to other issues, but is not usually dangerous on its own.

However, if a fan is wobbling because it was not installed correctly, it could be at risk of falling. For safety, it's always a good idea to ensure all mounting screws are tight and to address any wobbling or imbalance issues promptly.

Duct fans in HVAC systems last an average of 15 to 20 years. Because these fans operate in relatively controlled environments, they can maintain their efficiency for a long period of time. To maximize the lifespan of your duct booster fan, have your HVAC system maintained regularly.

While it may seem like it makes sense to put a fan in the attic to cool it down, it won’t be as effective as installing attic fans. Ventilation installed near the peak of the roof, whether passive (just allowing heat to escape) or active (drawing the air up and out) will be more effective at cooling the attic.

Blower fans are better for preventing mold growth than dehumidifiers because they target the damaged areas and increase the rate of evaporation, which dries out the building materials. Ideally, you should run blower fans and a dehumidifier, as this will allow the fans to move dry air over your damaged building materials, drying out the space even more quickly.
