Your entire residence should be a refuge that’s warm and comfy in the winter season and cool and comfortable in the summer. However, families who live in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the first floor.

This could merely be caused by the fact that most thermostats in a house are on the first 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 variations between the upstairs and downstairs could also be due to problems with your HVAC system. Some of these issues can be solved somewhat quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Myers Furnace Company 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 chalked up to several factors. First, heat rises, so it’s common for the second floor of a home to get hotter than the first floor. Insufficient insulation in the attic or roof can exacerbate this issue by allowing heat transfer from the roof into the upstairs rooms.

Another common reason is that the air conditioning is not big enough to cool the entire home, causing it to struggle to cool the upstairs properly.

To deal with these issues, homeowners could add extra insulation in the attic and make sure their home has proper 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 Myers Furnace Company inspect the unit. A skilled professional also can help select a unit that's better suited for your home if you want air conditioning installation or replacement.

Why Is My Upstairs Colder/Not Heating?

When the downstairs of your home is warm, but it’s freezing upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it should 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 on higher floors. It’s important 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 disseminating conditioned air throughout different locations of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the downstairs. A typical explanation for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, 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 location of the supply and return vents. If there are fewer vents on the upper story or they aren't well located, it can limit air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, decreasing the overall efficiency of the HVAC system and exacerbating the temperature difference.

To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by skilled HVAC pros like the team at Myers Furnace Company to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help enhance 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 lower floors of your house, an HVAC zoning system could be a useful solution.

An HVAC zoning system separates the home 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 beneficial in situations where the upstairs of a multi-story home is too 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 easily.

Why Is the Humidity So High Upstairs?

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 higher levels are more humid than the lower level.

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 permit warm, humid air from outside infiltrate the upstairs rooms. Plus, 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 deal with humidity problems, homeowners can improve 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. Finding 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 useful tool to manage humidity on the upper and lower floors.
