User: How do I make sure that my house is energy efficient?
Assistant: One way to make sure your house is energy efficient is to seal any air leaks. Check around windows and doors for drafts or gaps where warm or cooled air can escape. Installing weather stripping or caulking can help to reduce these gaps. 2 Additionally, you should consider installing more energy efficient appliances and lightbulbs. Look for the Energy Star rating on appliances and make sure to get the bulbs with the highest number of lumens per watt. 3 Lastly, you can install a programmable thermostat which will regulate your heating and cooling system to help optimize your energy use.
