MAINTAIN YOUR HVAC
Have you changed your furnace or central air conditioner's filter this season? If not, this is a great time to do so. Take a few minutes to change it once every 3 months during times of heavy use.
CLEAR THE AIR
Take the time to dust those appliances that are often forgotten about. Dust bathroom vent fan covers as well as the ceiling blades in other rooms in your home. Clean dust and grease from the kitchen stove hood and exhaust fan.
KEEP BULBS and FIXTURES CLEAN
Don't let dirt absorb the light and reduce the efficiency. This is great time to wipe off and dust. Another tip: Replace incandescent light bulbs with LEDs and use up to 90% less energy.
CHECK ON YOUR FRIDGE
Clean dust from under your refrigerator, the front vent at the base, and any exposed coils at the backs. Another tip: make sure products aren't blocking the fan and vents inside the fridge and freezer. Finally: wait until your leftovers cool before putting them in the fridge.
REARRANGE FURNITURE
Central air conditioning vents aren't always in the most convenient places. Check that no furniture is obstructing them.
CLOSE OFF CERTAIN VENTS
Close off vents in unoccupied spaces in your home to help direct treated air to where you need it most. Pay special attention to basement rooms and lower levels, where cool air naturally settles. Closing vents in these spaces can increase comfort in other rooms that may heat or cool less easily.
