1. Check the sealing around windows and doors
Did you know that one of the most common mistakes people tend to make is not checking the window seal properly? Every summer or right before the cold season comes, make sure you check all the doors and windows for any cracks that might appear with time. Through these holes and gaps, the heat can escape from the house and leave the room chilly. How can you check that? Put your hand near the window to see if you can feel the air from outside.
It’s easy to solve this issue by simply sealing these areas with caulk to have a cozy, warm home and letting the cold stay out where it belongs.
