- Check your house
The best thing you can do is have a professional energy audit of your home – sometimes utility companies will even perform this service for free. If you cannot get an audit performed by a professional, you can do an amateur audit yourself. Go outside and check along windows and doors to see if there is cold air leaking out from inside. If you find leaks – seal them.
- Review thermostat placement
You want your thermostat to be in the main area of your home and out of the way of direct sunlight. If the sun is shining in on your thermostat, your AC is probably blowing more often than it needs to.
