Bathroom Exhaust Fan Replacement Ellicott City

Do exhaust fans really need so much love?
Homeowners in Ellicott City, MD are missing a simple, yet important functioning part of their bathroom. Exhaust fans are in most Ellicott City household bathrooms. Yet, as familiar as they are to homeowners, there are several important factors that are getting overlooked.

Here are 5 things about bath fans you might not know:

Most exhaust fans installed in Ellicott City, 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 an Ellicott City, MD 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 right
Incorrectly installed fans can act as gateways to the attic increasing BGE and Pepco energy bills

As it turns out, a bathroom exhaust fan is important for indoor air quality and should be installed correctly!
