- This monthPress the test button on every smoke and CO alarm.
An alarm you have not heard in months may have a dead battery or sensor. NFPA recommends testing smoke alarms at least once a month.
How
Hold the test button until it sounds. Anything silent or chirping: replace the battery, or the whole alarm if it is past its date.
- This monthCheck the HVAC filter and replace it if it is gray or clogged.
ENERGY STAR advises inspecting filters monthly: a dirty filter raises energy costs and can damage the equipment, leading to early failure.
How
Turn the system off, slide the filter out, and match the size printed on its edge. Arrow on the frame points toward the blower.
- WatchClean the dishwasher filter.
Most current dishwashers have a manual filter; when it clogs, dishes come out dirty and the drain pump strains.
How
Twist out the filter at the bottom of the tub, rinse it under the tap and scrub gently with a soft brush.
- WatchIf the fridge has a water filter, replace it.
Most refrigerator makers specify a filter change about every six months.
How
Check the model’s filter part number in the manual or on the filter itself.
- WatchUse the dry warm weeks for exterior painting, staining and caulking.
Paints and sealants need dry, warm days to cure, and the window is short here.
How
Scrape and prime bare wood first; follow the product’s temperature range.
