A Seasonal Maintenance Calendar for DMV Rental Properties

October 14, 2026 · 6 min read · Tilmon Properties

The Washington region puts buildings through a lot: humid summers, freeze-thaw winters, heavy spring rain and a serious fall leaf drop. Preventive maintenance on a predictable schedule costs far less than emergency repairs, and it keeps residents happy.

Fall (September–November)

Winter (December–February)

Spring (March–May)

Summer (June–August)

Year-round

TaskHow often
HVAC filter replacementEvery 1–3 months
Smoke & CO detector testEvery 6 months, plus at every turnover
Water heater flush & inspectionAnnually
Dryer vent cleaningAnnually
Interior unit inspectionAt least annually

Let us keep the calendar: Tilmon coordinates preventive maintenance, inspections and repairs with licensed, insured vendors, so owners don't have to track any of it.
