After a cool and wet spring, warm weather is set to blanket most regions of the country this week. But you’ll want to keep that hot air outside by #summerizing your home, if you haven’t already. Summerizing is just like winterizing, says doityourself, except that some of the appliances are different. Clean the air conditioning units and replace filters. Fix any missing or faulty caulk and weatherstripping. Put a towel underneath doors to prevent cool air form escaping. And finally, make sure that ceiling fans are rotating counterclockwise to direct cooler air downward.
