Best bathroom fan installation pros near Phippsburg, ME

Stainless steel or aluminum fans are long-lasting and have less air resistance. They are best for outdoor use as their durability helps them withstand unpleasant weather conditions. Their heavy weight requires a stronger motor, which leads to more noise than other blade materials.

Wooden fan blades are a classic, durable option. They are much quieter than metal fans and feature a wide range of styles and finishes to choose from. However, they can be damaged by moisture if not covered with plastic.

Plastic fan blades are lightweight, easy to clean, and versatile. There are various shapes and styles to choose from as plastic is easily molded and dyed. They will also deteriorate slower than other materials as they aren’t as susceptible to humidity and moisture.

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.

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.

Exhaust fans push air out of spaces, removing moisture, heat, odors, and pollutants. They vent air outside through ducts, preventing mold and improving air quality. Unlike ventilation fans, which circulate fresh air in and out, exhaust fans focus solely on expelling unwanted indoor air.
