Your entire residence should be a sanctuary that’s warm and comfy in the winter and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could just be due to the fact most thermostats in a house are on the first floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so it makes sense 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 difficulties can be sorted out relatively quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Morgner Inc. Air Conditioning & Heating will help you figure out why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hotter Upstairs?
The phenomenon of the upstairs of a two-story home getting hotter than the downstairs can be attributed to several factors. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Lack of insulation in the attic or roof can worsen this problem by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the HVAC system is not big enough to cool the entire home, causing it to fight to cool the upstairs effectively.
To tackle these issues, homeowners could install extra insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the air conditioning unit is the ideal size for the home, call an experienced HVAC company like Morgner Inc. Air Conditioning & Heating inspect the unit. A qualified professional also can help select a unit that's better suited for your home if you need 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 makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s important 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 very important role in disseminating conditioned air throughout different locations of the building. However, issues with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported cause for this is improper airflow balance. The ducts may not be the proper size or design, resulting in 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 upper story.
Another potential problem area in the ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they aren't well placed, it can limit air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by skilled HVAC pros like the team at Morgner Inc. Air Conditioning & Heating to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in more vents or adjusting existing ones can help enhance airflow and ensure a better 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 rest of your house, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system separates the residence 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 effective in scenarios where the upstairs of a multi-story home is quite 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, allowing them to address specific hot or cold spots easily.

Why Is it So Humid Upstairs?
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 higher levels are more humid than the first floor.
A typical explanation for excess upper floor humidity is poor ventilation on the upper floor, which can result in increased humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may permit warm, humid air from outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also cause excessive moisture in that section of a home.
To fix humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Adding more insulation in the attic and better sealing the attic and walls can help protect against 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.
