Your entire residence should be a sanctuary that’s warm and comfy in the winter season and cool and comfortable in the summer. However, families who live in some two-story homes find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could merely be caused by the fact that most thermostats in a house are on the ground floor, which is where people spend the most time—in the living room, kitchen, etc.—so they set the temperature according to how it feels on the first floor.
However, temperature variations between the upstairs and downstairs could also be caused by problems with your HVAC system. Some of these challenges can be solved fairly quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Woody's Sudden Service 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 getting hotter than the downstairs can be chalked up to several factors. For starters, heat rises, so it’s natural for the second floor of a home to get hotter than the ground floor. Insufficient 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 big enough to cool the entire home, causing it to struggle to cool 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 question of whether the air conditioning unit is the correct size for the home, call an experienced HVAC company like Woody's Sudden Service inspect the unit. A knowledgeable professional also can help find a unit that's better suited for your home if you are considering 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 a very chilly night for anyone whose bedrooms are on the upper floor. The most common causes of an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation lets cold air to filter through the home’s attic or walls and contribute to heat loss, causing colder temperatures upstairs. It’s essential to make sure your home has a deep, level layer of insulation in the attic and proper insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a critical role in disseminating conditioned air throughout different locations of the building. However, problems with the ductwork can result in the upstairs being colder than the downstairs. A frequently reported cause for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, creating an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, causing insufficient airflow—which is the heated air—on the higher floors.
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 poorly placed, it can limit air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted HVAC pros like the team at Woody's Sudden Service to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help enhance airflow and ensure a more consistent 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 rest of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system breaks the home into different zones, which each have their own thermostat and damper system so the homeowner can modify the heating or cooling of each zone.
This system can be particularly helpful in instances where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By installing a zoning system, homeowners can control 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 issue in multi-floor homes is when the upper floors are more humid than downstairs.
A common cause for excess upper floor humidity is poor 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 allow warm, humid air from outside the house infiltrate the upstairs rooms. And, if there are any leaks or plumbing issues on the upper floor, that can also cause excess moisture in that area of a home.
To fix humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Adding more 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 worthwhile tool to manage humidity in the residence.
