Every floor in your home should be a sanctuary that’s warm and toasty in the winter season and cool and comfortable in the summer. However, residents in some two-story homes find the upper floor is stubbornly hotter or colder than the first floor.
This could just be due to the fact most thermostats in a house are on the ground floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so as a result they tend to set the temperature according to how it feels on the first floor.
However, temperature discrepancies between the upstairs and downstairs could also be caused by problems with your HVAC system. Some of these challenges can be fixed somewhat quickly while others might necessitate more extensive and costly fixes. Here, the team at Aggressive Mechanical will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hot Upstairs?
The phenomenon of the upstairs of a two-story home feeling hotter than the downstairs can be chalked up to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Not enough insulation in the attic or roof can make this worse by permitting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not strong enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To deal with these issues, homeowners could install extra insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the air conditioner is the correct size for the home, call an experienced HVAC company like Aggressive Mechanical inspect the unit. A qualified professional also can help select a unit that's better suited for your home if you want air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most common explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to seep through the home’s attic or walls and contribute to heat loss, causing colder temperatures on higher floors. It’s essential to make sure your home has a thick, level layer of insulation in the attic and adequate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a critical role in circulating conditioned air throughout different rooms of the building. However, troubles with the ductwork can cause the upstairs being colder than the lower floor. A typical explanation for this is improper airflow balance. The ducts may not be the correct size or in the appropriate layout, resulting in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.
Another potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they are not correctly positioned, it can reduce air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and actually making the temperature difference worse.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted experts like the team at Aggressive Mechanical to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help enhance airflow and ensure a more consistent temperature balance between the upstairs and downstairs.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the ground level of your residence, an HVAC zoning system could be an effective solution.
An HVAC zoning system breaks the residence into distinct zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.
This system can be especially effective in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By investing in a zoning system, homeowners can manage the temperature independently in each zone, making it possible for them to address specific hot or cold spots effectively.

Why Is My Upstairs So Humid?
In addition to the upper story being hotter or colder than the rest of the house, another challenge in multi-floor homes is when the upper floors are more humid than the first floor.
A typical reason for excess upper floor humidity is weak ventilation on the upper floor, which can cause higher humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may permit warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing issues on the upper floor, that can also lead to unwanted moisture in that section of a home.
To fix humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help prevent external moisture from entering the upstairs. Locating and repairing any leaks or plumbing issues is also extremely important.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another helpful tool to reduce humidity on the upper and lower floors.
