Don't Forget These Fall Home Maintenance Jobs

Your furnace doesn't care that you're busy. Neither does the freeze coming in January.

Fall maintenance is the unglamorous stuff that keeps your house from punishing you all winter. Miss it now, pay for it later — sometimes with a service call on the coldest night of the year, sometimes with a four-figure repair that could've been a $60 fix. Here's what actually matters before the first hard freeze.

The furnace comes first

Get your furnace serviced. Not next month. Now.

This is the one task that separates wishful homeowners from people who stay warm when it's 12 degrees outside. A tech will check the heat exchanger for cracks (a carbon monoxide risk), test the ignition, clean the burners, and confirm the thing will actually run when you need it.

Can you do this yourself?

Some of it. You can swap the filter — and you should, every three months or when it looks like a lint trap. You can vacuum around the blower. You can make sure nothing is stacked against the intake. But the safety checks and the combustion analysis? That's a pro job. Furnaces involve gas, fire, and the silent killer. Not the place to wing it.

Expect to pay $100 to $200 for a tune-up. A membership plan from a local HVAC company sometimes bundles it with priority service and a discount on repairs, which is worth it if your furnace is over ten years old and you'd rather not gamble.

If your system is older and you're hearing new noises — banging, screeching, rumbling that wasn't there last year — mention it. That's the sound of something about to fail.

Check your carbon monoxide and smoke detectors

This takes five minutes and might save your life.

Press the test button. If it beeps, great. If it doesn't, replace the batteries or replace the unit. CO detectors expire after five to seven years. There's a manufacture date stamped on the back. If yours is older than that, it's junk. Toss it and buy a new one.

You want at least one CO detector on every floor, and one near the bedrooms. Smoke detectors in every bedroom, hallway, and the kitchen.

Not negotiable.

Weatherstripping and the invisible money leak

Your windows and doors are bleeding heat. You just can't see it.

Run your hand along the edges of exterior doors on a windy day. Feel a draft? That's conditioned air you paid for, leaving. Weatherstripping is cheap — a few bucks a door — and the adhesive-backed foam kind takes twenty minutes to install. Peel, stick, close the door. Done.

For windows, check the caulk around the frames outside. If it's cracked or peeling, scrape out the old stuff and run a fresh bead. (And yes, first-time caulking is awkward. Cut the tip at a shallow angle, go slow, keep a damp rag nearby to smooth it. It'll look better the second window.)

Interior storms or shrink-film kits work if you've got old single-pane windows and you're not ready to replace them yet. They're ugly but effective. Your heating bill will prove it.

Gutters: the job everyone hates

Clogged gutters don't just overflow. They ice up, they rot fascia boards, they dump water right next to your foundation where it can freeze and crack things.

Clean them before the leaves finish falling, or right after. Scoop the muck, flush with a hose, check that downspouts actually drain away from the house — at least four feet out, not into a puddle by the basement wall.

If you've got tall gables or a steep pitch and you're nervous, hire it out. A gutter cleaning runs $100 to $250 depending on the house. Worth it to avoid the ER.

Gutter guards are a maybe. They keep out big leaves but not pine needles or the gritty stuff that still clogs. Some people swear by them. Some people just clean twice a year and skip the $1,500 install.

Water, pipes, and the stuff outside

Disconnect your garden hoses and drain them. Shut off the valve to exterior spigots from inside the basement or crawlspace, then open the outside faucet to let any trapped water out. If you skip this and it freezes, the pipe splits. Then it thaws. Then your basement floods. Ask me how I know.

Check your sump pump if you have one. Pour a bucket of water in the pit. It should kick on and drain fast. If it groans or doesn't run, replace it before spring melt. They're about $150 for a decent pedestal model you can swap yourself, or call a plumber if it's a submersible in a tight spot.

If you've got an irrigation system, blow it out or hire someone to do it. Trapped water in the lines will crack valves and fittings. Repairs in spring will cost more than a fall blowout.

Chimney and fireplace (if you use it)

You don't get to skip this just because you only light three fires a year.

Creosote builds up. It's flammable. A chimney fire is fast and terrifying, and your homeowner's insurance will want to know when you last had it swept.

If you burn wood regularly, get it swept every year. If you use it occasionally, every other year is the standard line, but honestly every year is smarter. A sweep runs $150 to $300 and includes an inspection for cracks, blockages, and animals that moved in over summer.

Gas fireplaces need a look too — not a sweep, but a check of the pilot, the glass, and the venting. Carbon monoxide doesn't care what fuel you burn.

Roof and siding: look up, look close

You're not climbing up there. But you can stand in the yard with binoculars or zoom in on your phone.

Look for:

• Missing or curled shingles
• Flashing that's pulled away around vents or the chimney
• Sagging spots or dark streaks (water damage)
• Loose soffit or fascia

If you see something wrong, call a roofer for an inspection. Most will quote a repair for free. A few missing shingles are a $200 fix. Ignored for a winter, they're a $2,000 leak in your ceiling.

Check your siding while you're at it. Cracks in wood siding or gaps in vinyl let water and critters in. Caulk the small stuff. Replace broken boards before they rot the sheathing behind them.

Furnace filters, again

I already said it. I'm saying it again.

Every. Three. Months.

A $4 filter is cheaper than a new blower motor. If you have pets or you run the fan constantly, every two months. If your filter looks like a dryer vent after one month, you might have a duct leak or an air-quality problem. Worth checking.

When to stop and call someone

You should handle the easy stuff: filters, detectors, weatherstripping, gutters (if you're comfortable). Maybe caulk. Maybe a sump test.

You should NOT handle:

• Anything inside the furnace beyond swapping the filter
• Electrical panels or wiring
• Roof work if you're not confident or it's steep
• Gas lines, period
• Structural repairs

If you're staring at something and you're not sure, that's your gut telling you to ask. HireA.Tech connects you with one vetted local pro for exactly this situation — someone who's licensed, insured, and actually shows up. No endless calls, no sketch estimates from random internet ads.

The stuff people are worrying about right now (and whether you should)

Caulking disasters: Yes, it's awkward the first time. You'll use too much or too little, and the bead won't be perfect. It's fine. It still seals. Practice on a basement window before you do the front door.

Old railings that don't meet code: If you're not selling, you're probably fine. If you're selling and the inspector flagged the baluster spacing, you've got options short of ripping everything out — a local carpenter can usually add intermediate spindles or mesh for a few hundred bucks.

Mystery sand in the hot water lines: That's sediment from a dying water heater. Flush it. If it keeps coming back, the tank is corroding from the inside. Budget for a replacement.

Basements that look wet a few months after purchase: Not unusual, not great. Check grading, downspouts, and gutters first. If water is coming up through the floor, that's groundwater and you're into sump pumps, drain tile, maybe a real waterproofing job. Get a foundation specialist to diagnose it before you spend money guessing.

How long this actually takes

If you do it all yourself over two weekends:

• Furnace filter swap and detector test: 30 minutes
• Weatherstripping three doors: 1 hour
• Gutter cleaning (one-story house): 2–3 hours
• Caulking windows: 2 hours
• Exterior walkaround and hose disconnection: 30 minutes

If you hire out the furnace service, chimney sweep, and gutter cleaning, you're looking at $500 to $700 total and maybe two hours of your own time for the small stuff.

Either way, you're done before Thanksgiving. Then you get to spend the winter not worrying about it.

What happens if you skip it

Your furnace quits at 10 p.m. on a Saturday in February. No heat, no appointment until Monday, and the emergency rate is double. Or your gutters freeze into a dam that peels your fascia off. Or a pipe bursts while you're visiting family and you come home to a flooded basement.

Fall maintenance is boring. It's not satisfying like a kitchen remodel. But it's the difference between a house that works and a house that punishes you.

Do the list. Stay warm.
