Your entire home should be a retreat that’s warm and comfy in the winter and cool and comfortable in the summer. However, families who live in some multi-level residences find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could simply be because most thermostats in a house are on the first floor, which is where people spend the most 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 trouble with your HVAC system. Some of these challenges can be fixed fairly quickly while others might call for more extensive and costly fixes. Here, the professionals at Done Right Air will help you solve 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 becoming hotter than the downstairs can be traced 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. 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 conditioning is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs adequately.
To tackle these issues, homeowners could put in 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 proper size for the home, call an experienced HVAC company like Done Right Air inspect the unit. A knowledgeable professional also can help find a unit that's better suited for your home if you require air conditioning installation or replacement.
Why Is My Upstairs Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation permits cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. It’s crucial to make sure your home has a solid, 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 rooms of the building. However, troubles with the ductwork can result in the upstairs being colder than the main level. A common cause for this is improper airflow balance. The ducts may not be the right size or design, creating an uneven distribution of air between the floors. This can cause more warm air to go downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.
Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they are not correctly located, it can limit air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can cause air loss, decreasing 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 skilled experts like the team at Done Right Air to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help improve airflow and ensure a more even temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the ground level of your residence, an HVAC zoning system could be a great solution.
An HVAC zoning system separates the residence into distinctive 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 beneficial 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 control the temperature independently in each zone, making it possible for 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 lower level.
A common reason for excess upper floor humidity is poor ventilation on the upper floor, which can cause 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. And, if there are any leaks or plumbing concerns on the upper floor, that can also lead to excess 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 protect against 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 valuable tool to manage humidity on the upper and lower floors.
