Your entire home should be a retreat that’s warm and comfy in the cold months and cool and comfortable in the summer. However, owners of some multi-level residences find the upper floor is stubbornly hotter or colder than the main 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 the majority of time—in the living room, kitchen, etc.—so they set the temperature according to how it feels on the first floor.
However, temperature differences between the upstairs and downstairs could also be due to issues with your HVAC system. Some of these issues can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the team at Dave's Diversified Services will help you figure out why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is My Upstairs So Hot?
The phenomenon of the upstairs of a two-story home feeling hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s common for the second floor of a home to get hotter than the first floor. Poor 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 conditioner is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.
To address these issues, homeowners could install extra insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioning unit is the correct size for the home, call an experienced HVAC company like Dave's Diversified Services inspect the unit. A knowledgeable 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 freezing upstairs, that can cause a very chilly night for anyone whose bedrooms are on the upper floor. The most common explanations for an upstairs not heating like it is supposed 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, resulting in colder temperatures upstairs. It’s crucial to make sure your home has a solid, level layer of insulation in the attic and appropriate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a very important role in distributing conditioned air throughout different locations of the building. However, troubles with the ductwork can cause the upstairs being colder than the lower floor. A common cause for this is improper airflow balance. The ducts may not be the correct size or design, creating an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing insufficient airflow—which is the heated air—on the upper story.
Another possible issue with the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper story or they are not correctly installed, it can reduce air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by skilled professionals like the team at Dave's Diversified Services to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help enhance airflow and ensure a more even temperature balance between the upstairs and downstairs.
How You Can Fix a Hot or 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 customize the heating or cooling of each zone.
This system can be particularly helpful in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By implementing a zoning system, homeowners can regulate the temperature independently in each zone, allowing 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 problem in multi-floor homes is when the upstairs is more humid than the first floor.
A frequent explanation for excess upper floor humidity is weak ventilation on the upper floor, which can produce greater humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may let warm, humid air from outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also cause unwanted moisture in that level of a home.
To fix humidity problems, homeowners can add more ventilation by getting fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help stop external moisture from entering the upstairs. Identifying 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 worthwhile tool to control humidity on the upper and lower floors.
