May home maintenance checklist

• Change the furnace filter for cooling season DIY
  Your air conditioner moves air through the same filter. Start summer with a clean one so the AC isn't working against a clogged filter.
• Clear around the outdoor AC unit DIY
  Pull out leaves, grass clippings and weeds, and trim plants back so there's open space on every side. The unit needs airflow to get rid of heat. AC and heat pump guide →
• Open the pool or service the hot tub Pro
  Have the pool opened and the pump, filter and heater checked, or test and balance the hot tub water after winter. Small leaks are cheaper to fix now than in July. Pool repair guide →
• Look over the deck and exterior wood DIY or pro
  Check for peeling stain, soft boards and loose railings. Re-stain or seal wood that's turned grey and absorbs water.
• Test GFCI outlets DIY
  Press the test button on outdoor, bathroom and kitchen GFCI outlets, then reset. If one won't trip or reset, have an electrician replace it.
• Service the garage door DIY
  Lubricate rollers and hinges, and test the auto-reverse by closing the door on a piece of wood. If it doesn't reverse, stop using the opener until it's fixed. Garage door guide →
