Your entire home should be a retreat that’s warm and toasty in the winter and cool and comfortable in the summer. However, owners of some homes with multiple levels 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 main floor, which is where people spend the greatest amount 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 variations between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these issues can be sorted out somewhat quickly while others might call for more extensive and costly fixes. Here, the team at Air Temperature Control 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 feeling hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Poor insulation in the attic or roof can worsen this problem by allowing heat transfer from the roof into the upstairs rooms.

Another common reason is that the air conditioner is not strong enough to cool the entire home, causing it to struggle to cool the upstairs sufficiently.

To address these issues, homeowners could install additional insulation in the attic and make sure their home has proper ventilation. If there’s concern the AC is the correct size for the home, call an experienced HVAC company like Air Temperature Control inspect the unit. A skilled 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 frequent reasons an upstairs not heating like it ought 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, creating colder temperatures on the upper levels. 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 cause the upstairs being colder than the main level. A frequently reported cause for this is improper airflow balance. The ducts may not be the proper size or configuration, causing an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.

Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly installed, it can restrict air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can lead to air loss, lowering the overall efficiency of the HVAC system and making the temperature difference more pronounced.

To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted professionals like the team at Air Temperature Control to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help increase airflow and ensure a better 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 house, an HVAC zoning system could be a highly effective solution.

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

This system can be very helpful in instances where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By implementing a  zoning system, homeowners can manage the temperature independently in each zone, making it possible for them to address specific hot or cold spots effortlessly.

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 higher levels are more humid than downstairs.

A frequent explanation for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in increased humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may permit warm, humid air from outside infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems on the upper floor, that can also create excess moisture in that level of a home.

To address 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 stop 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 useful tool to reduce humidity in your home.
