Every floor in your home should be a sanctuary that’s warm and comfy in the winter 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 rooms on ground level.

This could simply 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 as a result they tend 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 issues can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the team at E.B. Air will help you determine 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 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. 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 conditioner is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs properly.

To address these issues, homeowners could put in additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioner is the right size for the home, call an experienced HVAC company like E.B. Air inspect the unit. A knowledgeable professional also can help locate a unit that's better suited for your home if you require 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 could result in a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent reasons 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, causing colder temperatures upstairs. It’s essential to make sure your home has a deep, 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 critical role in distributing conditioned air throughout different rooms of the building. However, troubles with the ductwork can cause the upstairs being colder than the main level. A common cause for this is improper airflow balance. The ducts may not be the correct size or design, causing 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 upper story.

Another factor with ductwork is the layout of the supply and return vents. If there are fewer vents on the upper floor or they are poorly placed, it can limit air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, lowering 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 experts like the team at E.B. Air to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in more vents or adjusting existing ones can help increase 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 home, an HVAC zoning system could be a useful solution.

An HVAC zoning system divides the residence into different zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.

This system can be particularly helpful in scenarios where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By implementing a  zoning system, homeowners can control the temperature independently in each zone, enabling 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 upper floors are more humid than the first floor.

A frequent explanation for excess upper floor humidity is poor ventilation on the upper floor, which can cause higher 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 outside infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also lead to extra moisture in that section of a home.

To fix humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Proper 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 extremely important.

Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another worthwhile tool to reduce humidity in the residence.
