Make sure the areas around the vents are clear so that nothing blocks your airflow—on both outlets and return air strainers
In the summer you don’t need more humidity in home. It will just make your air conditioning have to run longer. Thus, Make sure you set it to the “summer” or “off” setting before starting your AC.
This may not add much heat to your home, but little things can add up over time. Also remember to keep lights and televisions off when not in use.
