Many of us turned our air conditioning on Tuesday - and soon, we'll be running it full blast for the summer.
But how can you make sure that cool air is being kept inside, and not escaping outdoors?
William Findley does free energy audits for NECAC for financially-eligible residents, and he says he always checks a couple of things: that there's sufficient insulation, and that windows and doors are properly sealed to keep the air in.
He says there's also plenty of things homeowners can do on their own that help.
"You can get weather stripping for doors, windows, new sash locks for windows that just keep the windows tighter, so that there are none of the air that comes up against the house actually gets in, and you don't have to be very skilled at contracting work, construction work," he said.
Findley says it's easier to lose the cool air and run up a higher utility bill in the summer, than it is to keep the house warm in the winter.
