Clean gutters. Inspect gutters to ensure all spikes, straps and clips are tightly fastened. Use a garden hose to flush debris from downspouts. Make sure downspouts or splash backs direct water at least three feet away from the foundation.
Wash windows, inside and out, using a solution made from three tablespoons of non-sudsy ammonia to 1 gallon of water. Don’t work in the direct sun — the solution will dry too fast and streak. To clean windows with real (not removable) grills, use a hacksaw to cut a squeegee so it fits the windowpanes exactly.
Have central air-conditioning unit checked according to the recommendations of the unit’s manufacturer. Replace the filter in the forced-air system. Clean debris from condenser or heat pump located outside.

Have swimming pools cleaned. Inspect and service pool liners and filters.
Shop for seasonal sales on air-conditioning units and window fans.
Dust ceiling fan blades.
Set thermostats and automatic sprinkler systems to adjust for weather changes.
Inspect and repair or repaint all patio and deck furniture.
