Why Your Second Floor Is Hotter Than Your First Floor

Two story home could have AC zoning issues

The simple fact is—heat rises. So it should come as no surprise that the rooms on your second floor are a little warmer than those on the first floor. But is it possible for you to change this? Here are a few factors that could be making the temperature gap more noticeable.

Closed or Blocked Air Vents

This one might seem like common sense. But sometimes when there is an issue, it’s good to start with the most obvious. A closed or blocked air vent will prevent proper air circulation and create zoning throughout your home. Check all the vents on your second floor to ensure that they are open and not blocked by furniture or other household items. If you find that all the vents are open, clear, and unobstructed, something else might be the issue.

Ductwork Issues

When is the last time you checked your ducts? If you are not keeping up with your annual HVAC maintenance, your duct system could be full of dirt and debris. This decreases the flow of air and could contribute to your second floor being warmer than your first. Your ductwork could also have a leak which simply means that the air leaks out of the network before it has the chance to make it to your second floor. If you suspect that the issue lies with your ductwork, contact the Air Hawk team and we will come out and inspect your system.

Insulation Issues

If you have confirmed that neither the vents nor the ductwork are the problem, the next culprit to check is your insulation. When your home is properly insulated, it prevents heat and air from escaping your home. Insulation also creates a barrier to help prevent the heat from the sun from gathering in the upper section of your home. This helps reduce the temperature gap between your upper and lower levels. Not sure if you have insulation issues? Our HVAC technicians can help you determine if you need to reinsulate your home and recommend the best thermal resistance for your home.

Overheated Roof

Could your roofing be causing your second floor to be warmer? The type of material used for your roofing plays a factor into the amount of heat that enters your home. If you have an older home, it’s likely that energy efficient materials were not used in the construction of your roof. This could be creating a warmer climate on your second floor. Consult a professional to determine if you should consider new roofing.

Air Conditioning Unit

If you find that none of these factors are causing your zoning issues, it just might an issue with your air conditioner. Overtime, your AC unit becomes inefficient at properly supplying cool air throughout your home—especially to your second floor. Depending how long you’ve had your unit, it might be time for a new air conditioner. If your unit is relatively new, it might be in need of repair. Contact Air Hawk for an evaluation and we will help you determine the best solution for you.
