The post 6 Things Homeowners Should Do Before September Slips Away first appeared on Crafting Your Home.
September has a way of disappearing faster than it should. One week it’s still warm enough for the pool, and the next, the calendar flips to October, and half the tasks that needed to do before the cold arrived never got started.
According to home maintenance experts and national safety organizations, a handful of specific tasks belong on this month’s list, not next month, since several of them lose most of their value once winter weather sets in.
Clean Out the Dryer Vent

It’s one of the most overlooked fire hazards in an average home. According to the National Fire Protection Association, clean dryer vents at least once a year to reduce fire risk, and real estate platform Zillow points to September as a smart time to do it, since laundry loads tend to pick up as back-to-school routines settle in.
The task is straightforward: locate the vent behind the dryer, disconnect the machine, vacuum and brush out the vent thoroughly, then reconnect everything and clear any built-up lint from the trap. According to Zillow, most homeowners can do this themselves, though anyone uncomfortable working behind a large appliance can hire a professional instead.
Test Every Smoke and Carbon Monoxide Detector
As furnaces and fireplaces start getting used again after months, working detectors matter more than ever. According to insurance company State Farm’s fall maintenance guidance, testing smoke and carbon monoxide detectors is one of the simplest tasks homeowners can do on their own, requiring only fresh batteries and a few minutes per device.
It’s an easy task to keep putting off precisely because it takes so little effort, which is exactly why September, before heating systems go into daily use, is the right moment to get to it.

Seal Air Leaks Around Doors and Windows
Small gaps around windows and doors do more damage to an heating bill than most homeowners realize. According to weatherization guidance citing U.S. Department of Energy estimates, gaps in weather stripping can account for up to 10 percent of a home’s total heating costs over a season.
According to State Farm, checking and resealing this weather stripping is a basic homeowner task that doesn’t require professional help in most cases. Walking the perimeter of home doors and windows with a simple caulk gun or replacement weatherstripping in September means the fix is in place well before the furnace needs to work overtime to compensate.
Switch Ceiling Fans to Their Winter Rotation
Most ceiling fans have a small switch that reverses their spin direction, and very few homeowners use it. according to home insurance provider Hippo, switching a ceiling fan to spin clockwise pushes warm air that naturally rises back down into the room, helping circulate heat more efficiently once temperatures drop.
It’s a five-second adjustment, usually made with a small switch located just under the fan blades or on top of the fan housing, and according to Hippo, reversing it back to counterclockwise in spring restores the direct cooling breeze most people associate with ceiling fans in summer.
Give the Chimney Proper Clearance and Protection
For homes with a working fireplace, September is the right time to prepare for it before it goes back into regular use. Danny Lipford, a nationally recognized home improvement expert and host of the syndicated television show Today’s Homeowner, recommends ensuring the chimney has at least ten feet of clearance around all sides of the flue, along with installing screens to keep falling leaves and nesting animals from getting inside.
According to Lipford, this kind of chimney and fireplace inspection is one of several September tasks meant to keep a home safe and efficient heading into the colder months, alongside HVAC tune-ups and similar seasonal checks.
Replace HVAC Filters Before the System Runs Constantly

A clogged HVAC filter forces a heating system to work harder than it needs to, and according to Hippo’s fall maintenance guidance, replacing or upgrading HVAC filters is one of the simplest, lowest-cost tasks a homeowner can knock out in a single afternoon. While experts generally recommend a full professional HVAC inspection once or twice a year, ideally in spring and fall, most homeowners can handle filter replacement without outside help.
Doing this in September, before the system shifts into daily use, means better airflow and lower strain right when the furnace needs it most.

Why the Timing on These Actually Matters
None of these six tasks are complicated, and most take less than an hour individually. What makes September specifically important, according to home maintenance experts, is that cooler weather makes outdoor work more comfortable, contractor schedules tend to open up once the summer rush ends, and small preventive fixes handled now are consistently cheaper than the repairs they prevent once winter weather actually arrives.
Skip this window, and most of these same tasks become harder, colder, and considerably more urgent by the time November rolls around.
