"I had Local Handyman help me with a long list of “to do’s” I had been avoiding. They helped me with multiple interior and exterior projects. Their communication from beginning to end was fabulous. They helped me evaluate the scope of the work against other bids I received. Their work was professional, their men arrived on time and they completed everything in a timely and quality manner. I will hire them again."

Bathroom Fan Installation FAQs, answered by experts

A small wobble isn’t worrisome, especially when you’re using your fan at top speed, but a significant one is. Ball joint fans, which are used on sloped ceilings, are more likely to wobble than a standard fan based on their design. But even then, you shouldn’t see significant wobbling, as this can be a sign of a bad installation.

Depending on the thickness of the carpet, it can take anywhere from 4 to 12 hours for carpet to dry with a fan. The humidity and temperature of the room also play a role in drying time, as added moisture in the air can result in longer drying time. 

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

Whole-house fans cost significantly less to run than a window AC unit. You'll pay an average of $0.01 and $0.05 per hour to run a whole-house fan compared to $0.06 to $0.88 per hour for the cost to run a window AC, depending on its size and the size of your home. They also use far less electricity than traditional central AC units.

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.
