Heating, ventilation & cooling
Check radiator valves for leaks
Finding and fixing a leak in a radiator valve early prevents damage to the floor and below.
Garage
Check the door between house and garage
A good seal on the door to your attached garage keeps out fumes and other hazards.
Structure & exterior
Clean the gunk from your gutters
Cleaning leaves and other debris from your gutters is a simple chore that can keep your basement dry.
Kitchen
Clean the refrigerator coils
Your refrigerator is the biggest user of electricity in your home. Clean its coils to keep it running efficiently.
Yard
Cut back some perennials before winter
Some perennials are more likely to survive the winter if you cut them back in fall.
Have your home electronics serviced
The components in your home theater gather dust

even if you use them every day. Have them professionally cleaned and serviced each year for top performance.
I hope these tips will be helpful to you.
