Get on schedule with your favorite heating and air conditioning company, and have your system serviced before you turn on your heat.
Check windows and doors on the exterior for peeling paint and cracked caulked. Vinyl windows have weep holes at the bottom so make sure the weep holes are clear of debris.
Inspect brick mortar and other hard surfaces for cracks. Seal these cracks and point up mortar to prevent moisture intrusion.
Check the roof for loose or missing shingles, loose or exposed nails, and check flashing for cracks and openings. Repair as needed using roofing tar and replacement shingles. Check the plumbing roof vent boots for cracks and openings. Replace the boot if needed. Hiring a roofing contractor may be a wise decision for this task.
If you have large trees or shrubs close to the home, make sure they are trimmed back at least one foot to avoid branches damaging the exterior of the home or roofing.
Check and clear gutters and downspouts of leaves and debris. If you have trees around your home, consider installing gutter guards. Check the gutter and downspout mounting devices for security and make needed repairs.
Remove garden hoses or other attachments from the hose bib and store for the winter.
Check the batteries in your smoke detectors and CO (Carbon Monoxide) detectors, if installed. A beep every thirty seconds from a smoke detector is a warning that the battery needs replaced.
Check all the exterior vents for your appliances and exhaust fans; the combustion vent intake (gas heating only), the dryer vent, range hood and bathroom exhaust vents. Make sure they are all clear, functional and the screens are clean.
