Your entire residence should be a retreat that’s warm and comfy in the winter season and cool and comfortable in the summer. However, families who live in some multi-level residences 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 ground floor, which is where people spend the greatest amount 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 differences between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these challenges can be solved somewhat quickly while others might call for more extensive and costly fixes. Here, the team at Tri County Climate Control LLC will help you figure out 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 becoming 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. Lack of insulation in the attic or roof can make this worse 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 struggle to cool the upstairs adequately.

To tackle 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 AC is the proper size for the home, call an experienced HVAC company like Tri County Climate Control LLC inspect the unit. A qualified 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 So Cold/Not Heating?

When the downstairs of your home is warm, but it’s very cold upstairs, that makes for a frosty 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 filter through the home’s attic or walls and contribute to heat loss, causing colder temperatures upstairs. It’s essential 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 main level. A typical explanation for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, 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 story.

Another possible issue with the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly positioned, it can reduce air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can cause 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 trusted HVAC pros like the team at Tri County Climate Control LLC 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 home, an HVAC zoning system could be a great solution.

An HVAC zoning system divides the household 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 especially effective in situations where the upstairs of a multi-story home is very hot or extremely cold while the main floor is comfortable. By setting up a  zoning system, homeowners can control the temperature independently in each zone, allowing them to address specific hot or cold spots effectively.

Why Is it So Humid Upstairs?

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 typical reason for excess upper floor humidity is weak ventilation on the upper floor, which can cause greater humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may allow warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also cause 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 protect against external moisture from entering the upstairs. Locating 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 useful tool to manage humidity on the upper and lower floors.
