Boise Fall Home Maintenance Checklist: 8 Things to Do Before Winter
Boise falls are beautiful — crisp mornings, golden leaves, and that brief perfect window between AC season and furnace season. But when the temperature drops, it drops fast. And the things you didn't check in October become emergencies in January.
Here's your fall maintenance checklist — what to do now, before the first freeze.
1. Get Your Furnace Inspected
This is number one for a reason. Every HVAC company in the valley gets booked solid by mid-November. A $120 fall tune-up catches small problems before they become no-heat emergencies in December. Your technician will check the heat exchanger for cracks (a carbon monoxide risk), test the ignition, clean the burners, and replace the filter.
If your furnace is over 15 years old, ask whether it's time to replace it. A new high-efficiency furnace can cut your heating bill by 20-30% — and Boise winters mean that savings adds up.
2. Clean Your Gutters — Really Clean Them
Boise's cottonwoods and maples drop a lot of leaves. Clogged gutters overflow and dump water against your foundation. In freezing weather, that water turns to ice, expands, and cracks your foundation. Clean gutters now, and check them again after the last leaves fall.
If you have a two-story home or steep roof, hire this out. A $150 gutter cleaning is cheaper than an ER visit.
3. Shut Off and Drain Outdoor Spigots
Frozen outdoor pipes are the most common winter plumbing emergency in Boise. Disconnect all hoses, shut off the water supply to outdoor spigots, and drain them completely. If you have an irrigation system, schedule a sprinkler blowout — most landscaping companies offer this for $75-$125.

4. Seal Gaps Around Windows and Doors
Walk around your house with a candle or incense stick on a breezy day. If the smoke wavers, you've got a draft. A $10 tube of caulk and an afternoon of sealing can cut your heating bill by 5-10%. Pay special attention to the gap between the foundation and siding.

5. Inspect Your Roof
Boise doesn't get the snow load of the Rockies, but freeze-thaw cycles are rough on roofs. Look for curled, cracked, or missing shingles. Check the flashing around chimneys and vents. A small leak now becomes a big problem when snow melts and refreezes.
If you're not comfortable on a ladder, most roofing companies offer free inspections.
6. Test Your Sump Pump
If you have a basement, you probably have a sump pump. Pour a bucket of water into the pit and make sure it kicks on. A dead sump pump plus melting snow equals a flooded basement. Replace it every 7-10 years regardless.
7. Reverse Your Ceiling Fans
Most ceiling fans have a switch that reverses the blade direction. In winter, blades should rotate clockwise at a low speed. This pushes warm air that's risen to the ceiling back down into the room. It's free and takes 30 seconds per fan.
8. Pest-Proof Before They Move In
When temperatures drop, field mice look for warmth — and they can squeeze through a hole the size of a dime. Check your foundation, garage door seals, and any gaps where pipes enter the house. A tube of steel wool stuffed into gaps blocks rodents better than foam (they can't chew through it).
The $500 Rule
A few hundred dollars of fall maintenance saves thousands in winter emergency repairs. Furnace check: $120. Gutter cleaning: $150. Sprinkler blowout: $100. Sealing gaps: $30. Total: about $400. One frozen pipe repair: $1,500+. One furnace replacement: $5,000+.
The math isn't complicated. Do the small stuff now.
