No wonder your upstairs is hot.
Hot upstairs attic fan.
Add extra insulation to your roof and attic.
Reduce use of lights and appliances avoid generating additional heat upstairs.
An attic fan works by exchanging the hot air in your attic space for fresh air pulled through the vents.
Try adding a couple of ceiling fans in the upstairs rooms or over a large open 2 story room such as a loft.
Hot air rises and cold air sinks.
These fans are commonly mounted in an upstairs stairwell or hallway ceiling where there s at least 3 ft.
An often overlooked issue for causing hotter rooms upstairs is how your roof is absorbing heat.
Attic ventilation fans help cool air your attic by pushing out the stifling hot air from inside the attic and bringing in cool air from outside.
You can even air seal your attic to prevent heat from seeping in.
This prevents hot air from seeping into your home and driving up the temperature in the living space which reduces the load on your air conditioner.
Of clearance above the fan.
A powerful fan draws cooler early morning and evening air through open doors and windows and forces it up through the attic and out the roof vents.
When the attic and attic access are not properly sealed and insulated the hot air coming in through the roof can leak into the lower floors of the home.
Therefore you can create a barrier between your attic and second floor with insulation.
If your upstairs is too hot the likely problem is poor insulation in your attic or bad ventilation throughout the home.
This sends hot air up and out cooling your house and your attic.
Combine this with the hot air rising from the lower floors and you re looking at a perfect recipe for uncomfortable upstairs environments.
This will help to avoid premature damage to the shingles or mold building up in moist hot.
By replacing the register covers with register fan units more cold air is forced out of the upstairs ducts.
Of course the simplest but not the best solution is to just use a stand alone fan in a specific hot room.
The temperature in your attic typically far exceeds the temperature outdoors and this creates a blanket of hot heat that just sits on top of your second floor.
It s being attacked from both sides.
They are typically easier to install and won t detract from the appearance of your roof.
If your roof is not deflecting the sun s rays every well it will absorb the sun s heat.
Use an attic fan and whole house fan.
As the heat builds up inside your attic it can cause the top floor of your house to feel much hotter and make your hvac system work harder.
Also adding an attic fan will help cool things down by circulating the air up there and decreasing the amount of hot air reaching your second floor.
Your attic insulation has a big impact on your second floor.
