Every floor in your home should be a sanctuary that’s warm and comfy in the winter season and cool and comfortable in the summer. However, families who live in some two-story homes find the upper floor is stubbornly hotter or colder than the main floor.

This could simply be due to the fact most thermostats in a house are on the ground floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so they set the temperature according to how it feels on the first floor.

However, temperature differences between the upstairs and downstairs could also be due to issues with your HVAC system. Some of these difficulties can be resolved somewhat quickly while others might call for more extensive and costly fixes. Here, the team at Refrigeration Systems Ltd. will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.

Why Is It Hotter Upstairs?

The phenomenon of the upstairs of a two-story home becoming 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. Insufficient 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 struggle to cool the upstairs properly.

To address these issues, homeowners could put in extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the AC is the ideal size for the home, call an experienced HVAC company like Refrigeration Systems Ltd. inspect the unit. A knowledgeable 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 So Cold/Not Heating?

When the downstairs of your home is warm, but it’s extremely chilly upstairs, that could result in a frosty night for anyone whose bedrooms are on the upper floor. The most common causes of an upstairs not heating like it is supposed to are the insulation levels and the ductwork.

Inadequate insulation enables 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 adequate 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 lower floor. A common reason for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, which results in 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 upper story.

Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they are poorly installed, it can reduce air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, lowering 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 examined by skilled professionals like the team at Refrigeration Systems Ltd. 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 rest of your house, an HVAC zoning system could be a useful solution.

An HVAC zoning system breaks the household into different 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 particularly beneficial in situations where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By investing in a  zoning system, homeowners can regulate 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 problem in multi-floor homes is when the upstairs is more humid than downstairs.

A frequent cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can cause 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 outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also lead to excessive moisture in that area of a home.

To correct humidity problems, homeowners can improve ventilation by using fans or opening windows to promote airflow. Appropriate levels of 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 worthwhile tool to manage humidity on the upper and lower floors.
