❄️the list I run before the first cold snap

What I actually do every October, learned by skipping half of it one bad winter and paying for it in January.

01
Bleed the outdoor hose bibs and shut off their water
(learned this one late) skip this and a pipe cracks in the first hard freeze, ask me how I know
02
Book the furnace service appointment now
not after the first cold night, when every HVAC company in town is booked two weeks out
03
Change the furnace filter
definitly the easiest one on this list, still skipped it two years running
04
Set a recurring reminder to change it again in 90 days
05
Reverse the ceiling fans to spin clockwise
pulls warm air back down off the ceiling instead of just stirring cold air around
06
Caulk the gaps around window and door frames
the most boring hour on this whole list and also the one that saves the most money
07
Add weatherstripping to the front and back doors
08
Open the south-facing curtains during the day, close them at night
free heat while the sun's up. close them again once it's dark or you lose it right back out the glass
09
Insulate exposed pipes in the crawlspace or garage
10
Test every smoke and carbon monoxide detector
do this first, honestly, before anything else here. heating season is when CO calls actually go up
11
clean the gutters before the first hard freeze
wet leaves plus ice is how you get a dam and a soaked ceiling
12
get the chimney swept if you use the fireplace at all
13
restock ice melt and a bag of sand for the walkway
14
check the attic insulation depth while you're up there for anything else
most codes want 12-15 inches and almost nobody actually has that much
