Maintenance Tips for the Home:
1. Test your garage door opener monthly to ensure that it reverses when it hits an obstruction or when its sensor beam is interrupted.
2. Vacuum the clothes dryer's exhaust duct at least once a year. If the duct is plastic, replace it (it's a fire hazard). Rigid sheet-metal ducting is best.
3. Replace furnace filters quarterly, or as recommended by the furnace manufacturer.
4. Test all GFCI (ground fault circuit interrupter) outlets monthly. Press the test button and use a voltage tester to make sure the power goes off.
5. Clean leaves and debris from the condenser of a central air conditioner seasonally.
6. Once a year, vacuum the refrigerator coils underneath the appliance.
7. Have the fireplace chimney inspected and cleaned annually.
8. Inspect window and door caulking and weather stripping yearly.
9. Replace the batteries in smoke detectors yearly. And remember, even recent hard-wired smoke detectors have backup batteries that must be replaced. If you have never checked yours, do so.
10. Make sure all tree limbs and palm fronds are trimmed back and do not touch the roof or gutters. This can prevent shingle damage.
