As I get older, I remember less and less just to be candid. An old rule of thumb I was told once was to change your furnace filters when the time changes – the whole fall back, spring forward thing. The problem is two fold – #1, I eventually change them around that date and #2, the more modern filters with finer and finer filtration capabilities need to be changed more frequently – maybe every 60 days with a 1″ filter.
So, I created a small “change log” sheet that I taped on the side of the furnace to help me remember when I last changed them. It’s a simple thing – I just made a four column table where I could record the date I changed the filter. Done.
Here’s the PDF that you can print if you are interested.
