Do exhaust fans in bathrooms really need love?

Exhaust fans are in most household bathrooms.

Yet, as familiar as they are to Maryland homeowners, there are several important factors that are getting overlooked.

Five Important Bath Fan Things

Most exhaust fans installed in Maryland homes vent moisture directly into the attic.
--This causes mold
--This accelerates the age of the roof
--This degrades existing insulation
Bathroom exhaust fan ducts running through an attic can "sweat" during a Maryland winter if not insulated properly.
Different fan models exhaust different amounts of air per minute.
If an exhaust fan is making noise, that does not mean it is working properly.
Incorrectly installed fans can act as gateways to the attic increasing BGE and Pepco energy bills.

A bathroom exhaust fan is important for good overall household indoor air quality and should be installed correctly!

Answer - YES!

Bathroom fan replacement Maryland

5 things correctly installed bathroom fans do have:

The exhaust fan damper is vented through the roof or side wall.
A bath fan should be measured for how much air it is exhausting after installation.
A bathroom fan duct should be insulated to R-8 in Maryland's climate
A tightly pulled or rigid duct is preferred with a maximum run of 25'
The fan housing should be air sealed after installation to prevent air leakage
