Yes, each of these tips help keep cool air and warm air inside instead of escaping. These tips can still lower your energy bill during warm periods. Another thing you can do in warm climates is to make sure you have good air flow. Ceiling fans help keep air moving and cost less to run than an A.C. Turn the fans on before you leave in the morning, the A.C. will still kick on, but not as soon. You can also turn your A.C. up a few degrees while you are away, but only go up by 2-3 degrees otherwise your A.C. will work hard trying to get back to a comfortable level and end up using more energy than if you had kept it at it’s usual temperature. Hope that helps. Best wishes staying cool. 🙂
