• 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 splashbacks 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.
• Remove mineral deposits from faucet aerators and shower heads by soaking parts in
  white vinegar and scrubbing with an old toothbrush.
• 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 system to adjust for weather changes
• Before placing metal patio furniture outdoors, coat it with auto polish.
