Air Conditioning Tip from AC Express
Too Hot on the Second Floor?
If you live in a two-story home, you may have found yourself stuck in a situation where the first floor is cool and comfortable but the second floor is just too hot! Unfortunately, you may not notice the problem until the hot summer months come scorching in.
You may have tried making the air colder, and even left it there all day hoping it would help. But to your dismay, when you return home, the second floor is still much hotter than the first.
What Causes The Problem?
As you know, heat rises. If your AC unit is on the first floor, it has to push hot air out as cooler air enters a room. That means the system has to work harder to distribute cool air to the second floor.
There are a few factors that determine how hard your air conditioning unit has to work to cool your second floor:
- The number of rooms in the home.
- If the unit is outdated and needs replacing.
- How well equipped the system is for cooling.
Another reason why your second floor is too hot in the summer could be because of your roof. Unless your roof is somehow protected from the sun or deflects it, it will absorb the sun’s heat. This heat travels through the attic and into the second floor making it harder for the system to cool.
Ductwork, Insulation and Seals
Ducts are responsible for taking cool air from your system throughout the home. Any type of faulty ductwork like improperly installed installation, or leaking or old ducts will force the HVAC unit to work harder to cool your home. Another issue could be that there is not enough ductwork reaching the second floor.
Fix The Problem
Now that you know what can cause the problem, it's time to fix it!
Redirect airflow to the second floor
If you have a basement, you can locate your HVAC system's dampers on the ducts leading to the first floor and close them halfway down or more. This will push more airflow up to the second floor.
If you don't have a basement, or can't locate the dampers, you can close your first floor register vents down some which will also help push more air to the second floor.
Dirty filters will restrict some airflow throughout your home, so regular cleaning or replacement is highly recommended.
Insulate and ventilate the attic
Proper insulation in the attic will lessen the amount of heat that reaches the second floor. You should also make sure that the attic is ventilated to get as much heat and moisture out as possible. An attic fan will also help circulate the air, which in turn decreases the amount of hot air that reaches the second floor.
Close some, but not all, supply vents on the first floor for better circulation to the second floor. Also, make sure nothing blocks your vents upstairs, and that your air-return vents are open.
Seal all cracks, holes, and gaps around windows to prevent seepage.
Change the fan setting on your thermostat from "auto" to "on"
Keeping your air conditioning system's blower fan running constantly will help mix the air more evenly throughout the entire house. Keeping the fan running doesn't use a lot of energy and it can often lower you energy usage because your HVAC system won't need to cycle as often.
