Las Vegas home calendar: what to do each month
Last checked October 29, 2026
Short answer
The four dates every Las Vegas homeowner should know are the watering switches: Mar 1 (3 days a week), May 1 (Monday to Saturday), Sep 1 (3 days) and Nov 1 (1 day). Get the AC checked in spring and the furnace in fall, and change the filter monthly.
Every month: inspect, clean or change your AC and furnace filter (ENERGY STAR).
