Indiana winters swing hard — single-digit nights, ice storms, and enough freeze-thaw cycling to find every weak point in a home's exterior within a single season. Fall is when to get ahead of it, while the weather still makes outdoor work realistic to schedule and complete.
Most of what follows takes a single weekend to complete, and none of it requires specialized tools beyond a ladder and a garden hose. The goal isn't perfection — it's simply catching the handful of issues that turn into real emergencies once temperatures drop and stay there.
A good rule of thumb: if a task involves water (gutters, spigots, pipes) or combustion (the furnace, the chimney), it belongs on the fall list rather than getting pushed to spring.
Homeowners who tackle this list consistently every fall tend to have far fewer emergency calls in January than those who wait until the first freeze to think about it.
Furnace service
Schedule furnace service before the first cold snap, ideally in September or early October before HVAC companies get booked solid across the metro. A pre-season check catches a cracked heat exchanger, a failing igniter, or a dirty burner assembly while it's still a scheduled repair on your terms — not an emergency no-heat call in January when every other homeowner is calling the same handful of companies.
Gutters and downspouts
Clear gutters after leaves drop but before the first hard freeze locks debris in place. Clogged gutters that freeze solid can cause ice dams, which force water back up under shingles and into the roof deck — one of the more expensive winter-related repairs we see regularly, and almost entirely preventable with one thorough fall cleaning.
Exterior faucets and pipe insulation
Disconnect garden hoses and drain outdoor spigots before the first hard freeze of the season. A frozen hose left attached can cause the spigot itself to crack, sometimes leaking inside a wall where it's not discovered until spring thaw reveals the damage. Insulate any exposed pipes in unheated spaces like a crawl space, garage, or unfinished basement rim joist area while you're at it.

Roof and chimney check
Inspect the roof for any damaged or missing shingles before snow load and ice become a real factor, and have the chimney inspected and swept if it gets regular use during the colder months. Creosote buildup is a leading cause of chimney fires, and it's an easy thing to put off until it's actually cold enough outside to want a fire going, which is exactly the wrong time to discover a problem.
Weatherstripping and caulk
Check weatherstripping around every exterior door and re-caulk any gaps you find around window frames. This is inexpensive, takes an afternoon at most, and directly affects heating bills for the entire winter ahead.

Key takeaways
- Schedule furnace service in September or early October, before HVAC companies get booked solid for the season.
- Clear gutters after leaves drop but before the first hard freeze to prevent ice dams.
- Drain and disconnect outdoor spigots before the first hard freeze to avoid a cracked fixture and hidden leaks.
- Have the chimney inspected and swept before you actually need it, since creosote buildup is a leading cause of chimney fires.
