September home maintenance checklist

September is pre-heating season: furnace tune-up, chimney sweep, caulk, and fall lawn work.

12 tasks below. Not all apply to every climate or home —generate a personalized schedule in 30 seconds.

• Check HVAC filter (replace every 1–3 months)

  A clogged filter strains the blower and raises energy use — the #1 cheap fix in home maintenance.

• Book heating tune-up before heating seasonCALL A PRO

  Furnace/heat-exchanger checks are a safety item, not just comfort — cracked exchangers leak CO.

  Applies in: Cold winters

• Inspect washing machine hoses & under-sink connections

  Burst supply hoses are a top-3 insurance claim; braided hoses fail too.

• Test sump pump (pour a bucket of water)

  Sump pumps fail silently and are only ever needed suddenly.

  Only if your home has this feature.

• Inspect & re-caulk windows, doors, and siding joints

  A $6 tube of caulk is the cheapest insulation and rot prevention you can buy.

  Applies in: Cold winters, Mild / temperate

• Trim vegetation 12+ inches off siding & roofline

  Plants hold moisture against the house and give pests a bridge.

  Applies in: Hot & humid

  Only if your home has this feature.

• Re-seal deck / porch wood

  Water beads = sealed. Soaks in = reseal this season.

  Applies in: Mild / temperate

  Only if your home has this feature.

• Chimney sweep & inspectionCALL A PRO

  Creosote is fuel; one sweep a year removes the chimney-fire risk.

  Applies in: Cold winters, Mild / temperate

  Only if your home has this feature.

• Close / winterize poolCALL A PRO

  Freeze damage to pool plumbing is a spring surprise nobody wants.

  Applies in: Cold winters

  Only if your home has this feature.

• Pool: test water & clean skimmer baskets

  Weekly in season; the checklist marks the monthly deep-check.

  Applies in: Hot & humid, Hot & dry, Mild / temperate

  Only if your home has this feature.

• Fertilize & overseed lawn

  Fall feeding builds roots; spring feeding builds weeds.

• Clean bathroom exhaust fan grilles & test airflow

  Bath fans prevent the mold you'd otherwise be scrubbing.

  Applies in: Hot & humid
