Filters prevent dust and other allergens from circulating through the ductwork. However, blocked filters can make a furnace work much harder, causing it to run less efficiently and possibly reducing its lifespan. And a dirty filter won't be as effective as a clean filter at blocking dust from eventually making its way into your living spaces.
You'll receognize the GFIs by the little buttons between the plugs on outlets located in spots where electrical shock hazards exist, such as in the bathroom or near the kitchen sink. They're designed to prevent electrical shock by "tripping," or breaking the current. So, it's clearly a good idea to push the test & reset buttons regularly to make sure they're working.
Hidden leaks can, over time, cause damage to floors, ceilings beneath, or walls in adjacent rooms.
Turn on the faucet and check for leaks in the pipes under the sink. Look for mold on shower walls that could indicate there's leakage behind them. And check for cracks in the grout where the tub meets the floor.
Lawns naturally need sunlight to thrive. And there's less of it during the shorter days of late fall and winter. A mat of thick leaves can kill that grass you so carefully tended during the warmer months.
You must apply pre-emergent crabgrass killer before the crabgrass seeds germinate, which happens in the early spring when the temperature of the surface soil rises into the 50s and 60s. So, timing is critical.
