How to check for drafts/cold air seeping in - insulating windows?
Wondering if people here can share what they do to ensure all windows/doors are properly insulated and cold air doesn't seep into the home. It seems that this time of year, my furnace turns on very frequently. We have a 1400 sq ft semi home, temp at night is set to 22.5 and during the day around 19 to 20.5
I saw some videos on YT where people mention bubble wrap applying to windows as an easy and cheap way to insulate. How about doors around the house? Any other heat loss sources I should be looking into?
Furnace filter is changed every 1-2 months and for the past few months we've been using 3M merv 4-5 i believe (red and purple ones).
Appreciate if you share some ideas - I was also thinking of buying those kits from Canadian Tire to insulate.
