If you live in a multi-story house, you may be experiencing an obvious temperature difference between the first floor and the second floor. While this is not unusual for many houses, it’s important to know there are solutions. So, why are the upper levels warmer than the bottom, and what can be done to cool things down? Let’s find out!
Reasons why it’s hotter upstairs
The central air conditioner is on full blast, and fans are going, too, but it’s still super hot upstairs. What exactly is going on?
- Heat rises: You may have heard the old saying that heat rises. Heat does in fact rise. Because colder air is denser than warmer air, the cold air drops low to the ground and the hot air is pushed up.
- A lack of ventilation: Another possible cause for a very hot upstairs is a lack of proper ventilation. The first thing you should check is for furniture and other object blocking air ducts. Beds, dressers and bookshelves may be sitting over or pushed up against vents, blocking airflow to upstairs spaces.
- Roofs absorb and trap heat: Roofs that are in direct sunlight tend to absorb and trap the heat from the sun. This is why some upper levels in homes are hotter than the levels below. You can keep most of the heat out by installing extra insulation between the roof and upstairs ceilings.
- Using only one AC: It’s not unusual for there to be a single air conditioning installation in older Lexington, KY homes. With a split AC system, you can control the coolness of the upstairs and downstairs separately. This type of HVAC design provides comfort evenly throughout multi-story homes.
Ways to fix the hot upstairs problem
Just because your second story is much warmer than the first floor doesn’t mean it has to stay that way. Luckily, there are solutions to your heat problem:
- Replace old AC: An aging air conditioning system can be a money and energy sucker, and not be as efficient at cooling your home—especially the upstairs rooms. Also, make sure you get an AC system that’s the right size for your home so you know it’s cooling all your living spaces.
- Install a ductless system: Instead of a central air conditioning installation in Lexington, KY, you might want to consider a ductless system installation. These systems eliminate a majority of indoor air quality problems associated with ducted systems, while allowing for zoned heating and cooling.
- Repair ductwork: Damaged air ducts can divert conditioned air out through cracks, so the air (or most of it) never makes it to rooms on either floor. If your air conditioning system is fairly new, your roof and attic are properly insulated and the air vents are not obstructed, schedule a ductwork inspection to determine if there’s damage.
