Every floor in your home should be a sanctuary 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 main floor.

This could just be due to the fact 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 resolved relatively quickly while others might require more extensive and costly fixes. Here, the professionals at Premium Air Services LLC will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.

Why Is It Hot Upstairs?

The phenomenon of the upstairs of a two-story home feeling hotter than the downstairs can be chalked up to several factors. Number one, heat rises, so it’s common 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 powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.

To tackle these issues, homeowners could add additional insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the AC is the proper size for the home, call an experienced HVAC company like Premium Air Services LLC 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 very cold upstairs, that could result in a very chilly 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 lets cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures on higher floors. 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 distributing conditioned air throughout different rooms of the building. However, problems with the ductwork can contribute to the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, resulting in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing insufficient airflow—which is the heated air—on the upper story.

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 poorly placed, it can restrict air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, decreasing the overall efficiency of the HVAC system and actually making the temperature difference worse.

To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by skilled experts like the team at Premium Air Services LLC to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help enhance airflow and ensure a more even 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 house, an HVAC zoning system could be an effective solution.

An HVAC zoning system divides the household into distinct 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 situations where the upstairs of a multi-story home is quite hot or really 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 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 higher levels are more humid than the lower level.

A common cause for excess upper floor humidity is weak ventilation on the upper floor, which can result in greater humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing issues on the upper floor, that can also lead to unwanted moisture in that level of a home.

To correct humidity problems, homeowners can increase ventilation by using 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. Identifying and repairing any leaks or plumbing issues is also imperative.

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