Every floor in your home should be a retreat that’s warm and cozy in the winter 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 rooms on ground level.
This could merely be because most thermostats in a house are on the main 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 differences between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these difficulties can be resolved fairly quickly while others might require more extensive and costly fixes. Here, the professionals at Fairfield Heating & Cooling 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 becoming hotter than the downstairs can be traced to several factors. First, heat rises, so it’s common 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 letting 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 have difficulty cooling the upstairs properly.
To fix these issues, homeowners could put in more insulation in the attic and make sure their home has adequate 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 Fairfield Heating & Cooling inspect the unit. A qualified professional also can help locate 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 freezing upstairs, that can cause a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures on higher floors. 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 very important role in distributing conditioned air throughout different locations of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the downstairs. A frequently reported explanation for this is improper airflow balance. The ducts may not be the correct size or in the appropriate layout, causing 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 upper level.
Another possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly installed, it can reduce air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, decreasing 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 checked by skilled experts like the team at Fairfield Heating & Cooling 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 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 ground level of your home, an HVAC zoning system could be an effective solution.
An HVAC zoning system breaks the household 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 very beneficial in scenarios where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By setting up 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 challenge in multi-floor homes is when the upstairs is more humid than the lower level.
A typical explanation for excess upper floor humidity is inadequate 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 allow warm, humid air from outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also lead to extra moisture in that level of a home.
To correct 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. Finding and repairing any leaks or plumbing issues is also critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another useful tool to reduce humidity in the residence.
