Bathroom Exhaust Fan Replacement Rockville MD

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

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

  1. Most exhaust fans installed in Rockville Maryland homes vent moisture directly into the attic
           --This causes mold
           --This accelerates the age of the roof
           --This degrades existing insulation
  2. Bathroom exhaust fan ducts running through an attic can "sweat" during a Rockville, MD winter if not insulated properly
  3. Different fan models exhaust different amounts of air per minute
  4. If an exhaust fan is making noise, that does not mean it is working right
  5. 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!  

Correctly installed bathroom fan in a Rockville MD home:

  • The exhaust fan damper is vented through the side wall or roof
  • 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 Rockville Maryland climate
  • Rigid duct is preferred with a maximum run of 25'
  • The fan housing should be air sealed to prevent air leakage
