What should be on a summer cleaning checklist in Maryland?

Summer cleaning in Maryland centers on humidity and cooling. Prioritize mildew control in bathrooms, basements, and closets; HVAC filter changes and vent cleaning (your system runs hard all season); washing windows, tracks, and screens while it's dry; refreshing outdoor living spaces and entryways; and a fridge and kitchen deep clean before summer entertaining. A dehumidifier keeping indoor humidity around 40–50% prevents most summer mold and musty smells.

How do I stop mold and mildew in a humid Maryland summer?

Control moisture: run bathroom exhaust fans, use a dehumidifier to hold indoor humidity around 40–50%, and keep basements and closets ventilated. Wipe down damp areas (shower, grout, window sills) regularly, dry shower curtains and mats, and address any musty smell quickly — it's usually the first sign of mildew starting. Catching it early is far easier than removing established mold.

How often should I change my AC filter in summer?

In peak cooling season, check your HVAC filter monthly and change it roughly every 1–2 months — more often with pets or allergies. A clean filter keeps the system efficient and stops it from recirculating dust through the whole house, which is one of the biggest contributors to summer dust buildup in Maryland homes.
