Licensed electricians typically install bathroom exhaust fans, ensuring safe wiring and code compliance. If new ductwork is needed, an HVAC specialist handles the venting. A handyman may suffice for simple replacements, but new installations should involve a licensed electrician to ensure a safe and effective installation that lasts for years to come.
If you’re replacing an existing fan, purchase a fan with the same dimensions so you won’t have to make any additional cuts in your ceiling or wall to accommodate it.
Pay attention to the fan’s CFM (cubic feet per minute) rating. A larger bathroom generally benefits from a larger CFM rating. At a minimum, you need one CFM per square foot.
You’ll also want to look for the fan’s sones rating, which measures how loud the fan will be during operation. Higher numbers indicate louder fan operation. To keep things quiet, look for two sones or fewer.
Installing a bathroom exhaust fan takes two to four hours when new wiring and ductwork installation are required. For a simple replacement that involves no extra modifications, the process takes one hour or more. This installation ensures all electrical and ventilation requirements are met and provides optimal airflow to your bathroom.
Bathrooms with windows do not automatically require an exhaust fan if natural airflow sufficiently reduces humidity. However, relying solely on a window does not guarantee consistent moisture removal. An exhaust fan actively ejects humid air, preventing mold growth and damage to surfaces. Installing a fan ensures reliable and continuous ventilation regardless of window size or weather conditions.
Bathroom fans last 10 years with proper upkeep. Regular cleaning and prompt repairs extend the life and efficiency of the fan. When signs of aging, such as increased noise or persistent odors, emerge, the fan must be replaced promptly to maintain optimal ventilation and safeguard your bathroom from moisture-related damage.
Local building codes mandate that all bathrooms maintain proper ventilation through a fan or window system. Verifying these requirements before installation is essential to ensure safety and code compliance. Hiring a licensed professional ensures that your installation meets all local regulations, thereby reducing the risk of moisture-related damage and potential fines.
