Your entire residence should be a refuge that’s warm and comfy in the cold months and cool and comfortable in the summer. However, residents in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the rooms on ground level.

This could just be caused by the fact that 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 variations between the upstairs and downstairs could also be due to problems with your HVAC system. Some of these difficulties can be sorted out fairly quickly while others might call for more extensive and costly fixes. Here, the professionals at Appalachian Heating 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. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Not enough insulation in the attic or roof can worsen this problem by permitting 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 fight to cool the upstairs sufficiently.

To fix these issues, homeowners could install additional insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioning unit is the right size for the home, call an experienced HVAC company like Appalachian Heating inspect the unit. A knowledgeable professional also can help locate a unit that's better suited for your home if you need air conditioning installation or replacement.

Why Is My Upstairs Always Cold/Not Heating?

When the downstairs of your home is warm, but it’s freezing upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it should are the insulation levels and the ductwork.

Inadequate insulation lets cold air to filter through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. 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 critical role in circulating conditioned air throughout different locations of the building. However, problems with the ductwork can result in the upstairs being colder than the lower floor. A frequently reported reason for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, resulting in an uneven distribution of air between the floors. This can cause more warm air to go downstairs, causing insufficient airflow—which is the heated air—on the higher floors.

Another potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they are not correctly positioned, it can restrict air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can cause air loss, lowering 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 examined by skilled professionals like the team at Appalachian Heating 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 useful solution.

An HVAC zoning system separates 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 especially effective in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By installing a  zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots easily.

Why Is it So Humid 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 typical reason for excess upper floor humidity is weak ventilation on the upper floor, which can result in increased 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 cause extra moisture in that area of a home.

To address humidity problems, homeowners can improve ventilation by using fans or opening windows to promote airflow. Proper 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 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.
