Pre-Fall HVAC Prep: Safe DIY Checks for Pepperell Homeowners
First, shut down your heating or cooling system. Then, put on a proper dust mask before doing anything else. Use a flashlight to inspect the supply and return vents in your home, look for dust buildup, pet hair, or debris. Gently vacuum these surfaces with a hose attachment, but never use a shop vac or high-pressure air, which can damage ductwork. For accessible registers, remove the front grille and wipe down the interior with a damp microfiber cloth. If your home has baseboard heating, check for dust accumulation and wipe it down. In Pepperell’s older homes, pay extra attention to wood-frame ductwork, excess moisture can lead to mold. Learn more about air duct maintenance in Harvard for tips tailored to similar climates.
