Every floor in your home should be a retreat that’s warm and toasty in the winter and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.

This could simply be caused by the fact that most thermostats in a house are on the first 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 caused by problems with your HVAC system. Some of these issues can be resolved somewhat quickly while others might call for more extensive and costly fixes. Here, the specialists at Balance Point Heating & Cooling will help you solve 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 traced to several factors. For starters, heat rises, so it’s common for the second floor of a home to get hotter than the ground floor. Not enough insulation in the attic or roof can exacerbate this issue 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 fix these issues, homeowners could put in extra insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the AC is the ideal size for the home, call an experienced HVAC company like Balance Point Heating & Cooling inspect the unit. A knowledgeable professional also can help locate a unit that's better suited for your home if you want 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 makes for a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it is supposed to 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, resulting in 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 proper insulation in the walls to keep the cold out and the heat inside.

The ductwork in a home plays a fundamental role in disseminating conditioned air throughout different areas of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the correct size or design, creating an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, leaving insufficient airflow—which is the heated air—on the upper story.

Another potential problem area in the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they aren't well located, it can restrict air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.

To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced experts like the team at Balance Point Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in more vents or adjusting existing ones can help enhance airflow and ensure a better temperature balance between the upstairs and downstairs.

What Do I Do to Fix a Hot/Cold Upstairs?

If your upstairs is hotter or colder than the lower floors of your residence, an HVAC zoning system could be a great solution.

An HVAC zoning system divides the residence into distinctive zones, which each have their own thermostat and damper system so the homeowner can modify the heating or cooling of each zone.

This system can be very useful in instances where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By setting up a  zoning system, homeowners can control the temperature independently in each zone, enabling 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 problem in multi-floor homes is when the higher levels are more humid than the first floor.

A common explanation for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in 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 outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also cause unwanted moisture in that level of a home.

To fix humidity problems, homeowners can increase 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. Finding and repairing any leaks or plumbing issues is also critical.

Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another valuable tool to reduce humidity on the upper and lower floors.
