You might have the best air conditioning unit that money can buy. Your downstairs shows it because it's cool and comfortable, but your upstairs is still hot, almost as though you didn't turn the air conditioner on at all. Here are some tips for making sure that your upstairs stays cool with the air conditioner that you already have.
1. Insulate the Attic
Your first step is to make sure that your attic is properly insulated. You might think that insulation only matters in the winter because it helps keep the warm air in, but the truth is that it helps keep the warm air out during the summer. The goal of insulation is to make sure that the house's temperature is unaffected by the temperature outside. If you don't insulate your attic, the heat will gather in the attic and start to affect the temperature of the lower levels. If you do choose to insulate your attic, you will reduce the chances that your attic will gather a high level of heat and make the rooms beneath it warmer. As a bonus, you will enjoy lower energy bills during the winter because less heat will escape through the roof and the rest of the attic.
2. Ventilate the Attic
Your next step is to ventilate your attic. By keeping the warm air that is upstairs and in the attic moving, you will reduce the chances that it will gather and significantly affect the temperatures upstairs. You can do this by simply installing fans that push the warm air from the upstairs to the rest of the attic, where it more likely to gather.
3. Close the Drapes Upstairs During the Day
Keep sunlight out of the upper levels of your home in order to make sure you aren't accidentally adding heat. Keeping the lights off upstairs will also help.
4. Close Some of the Vents Downstairs
Finally, be sure that you consider closing some, but not all, of the vents downstairs. You want to be sure that you shift the balance of ventilation from only being downstairs to being partly upstairs and partly downstairs. By closing some of the vents downstairs, you can achieve this balance and force the cooler air from your air conditioner to the upper levels of your home.
