Your entire residence should be a refuge that’s warm and cozy in the winter season 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 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 differences between the upstairs and downstairs could also be caused by issues with your HVAC system. Some of these difficulties can be sorted out relatively quickly while others might require more extensive and costly fixes. Here, the professionals at Franklin's Heating & Air Conditioning, Inc 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 getting hotter than the downstairs can be chalked up to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the ground floor. Insufficient 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 HVAC system is not big enough to cool the entire home, causing it to have difficulty cooling the upstairs sufficiently.

To fix these issues, homeowners could add additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioning unit is the proper size for the home, call an experienced HVAC company like Franklin's Heating & Air Conditioning, Inc inspect the unit. A qualified professional also can help find a unit that's better suited for your home if you need air conditioning installation or replacement.

Why Is My Upstairs Colder/Not Heating?

When the downstairs of your home is warm, but it’s extremely chilly upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it should are the insulation levels and the ductwork.

Inadequate insulation lets cold air to seep through the home’s attic or walls and contribute to heat loss, causing colder temperatures upstairs. It’s crucial to make sure your home has a thick, 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 very important role in distributing conditioned air throughout different locations of the building. However, problems with the ductwork can contribute to 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, creating 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 level.

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 located, 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 making the temperature difference more pronounced.

To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced experts like the team at Franklin's Heating & Air Conditioning, Inc to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in additional vents or adjusting existing ones can help increase 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 rest of your residence, an HVAC zoning system could be an effective solution.

An HVAC zoning system breaks the home 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 especially helpful in situations where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By installing 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 the Humidity So High Upstairs?

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 upper floors are more humid than the first floor.

A common explanation for excess upper floor humidity is poor ventilation on the upper floor, which can result in higher 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. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also create excessive moisture in that section of a home.

To manage humidity problems, homeowners can improve ventilation by installing fans or opening windows to promote airflow. Appropriate levels of insulation  in the attic and better sealing the attic and walls can help prevent external moisture from entering the upstairs. Identifying 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 valuable tool to reduce humidity in your home.
