Outdoor Home Inspections for Energy Savings Before Winter

Prep your home for winter and lower your energy bills with a simple outdoor inspection checklist from APG&E. Discover what to check before the cold sets in.

As cooler weather starts to roll in, your home’s outdoor areas play a bigger role in your comfort—and your energy bills—than you might think. A quick outdoor inspection before winter can make a real difference in how efficiently your home holds heat and uses energy. With just a few preventive steps, you can stay cozy and save money when temperatures drop. 

Here’s what to look for before the first frost hits:

Seal Up the Leaks

Walk around your home and check for cracks or gaps around windows, doors, and your home’s foundation. Even small openings can let cold air seep in and warm air leak out. Caulking, weatherstripping, or foam sealant can make a quick fix that pays off all season long.

Inspect the Roof and Gutters

A healthy roof keeps warm air inside and moisture outside. Look for loose shingles, damaged flashing, or sagging gutters. Clean out leaves and debris so water can drain properly. Ice dams—frozen water that traps melting snow—are common culprits for roof damage and heat loss in winter.

Check Exterior Vents and Ducts

If you have exterior vents (for dryers, exhaust fans, or heating systems), make sure they’re not blocked by debris, nests, or lint buildup. Clear vents help your appliances run efficiently and safely.

Service or Cover Your Outdoor HVAC Unit

Your HVAC system works harder in cold weather, so give it a little TLC now. Remove leaves and dirt from around the unit, and if you’re not using it in winter, consider a breathable cover to protect it from the elements. If you haven’t had your system inspected recently, scheduling a tune-up can keep your heating costs in check.

Inspect Your Insulation and Siding

Walk around the house and look for signs of wear in siding or insulation around outdoor pipes and fixtures. Replacing worn or missing insulation can prevent heat loss and frozen pipes—two issues that can add up to costly repairs.

Trim Trees and Shrubs

Overgrown branches near windows, power lines, or the roof can pose problems in winter storms. Trimming them back now helps prevent damage and keeps sunlight reaching your home to naturally warm it during the day.

Check Outdoor Lighting and Security

Shorter days mean you’ll rely more on outdoor lighting. Replace bulbs with energy-efficient LEDs, and consider motion sensors to save energy while keeping your home safe and well-lit. 

Wrap-Up: Small Checks, Big Savings 

A fall outdoor inspection is one of the simplest ways to prepare your home for winter—and to avoid surprise spikes in your energy bill. These small steps can help your home stay warmer, safer, and more efficient all season long.
