Your entire residence should be a sanctuary that’s warm and toasty in the winter season 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 rooms on ground level.

This could just 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 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 because of problems with your HVAC system. Some of these issues can be sorted out somewhat quickly while others might call for more extensive and costly fixes. Here, the team at Gopher Heating and Air Conditioning will help you solve 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 getting hotter than the downstairs can be traced to several factors. Number one, heat rises, so it’s common for the second floor of a home to get hotter than the main floor. Poor 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 air conditioning is not big enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.

To address these issues, homeowners could put in additional insulation in the attic and make sure their home has adequate 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 Gopher Heating and Air Conditioning inspect the unit. A qualified 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 Colder/Not Heating?

When the downstairs of your home is warm, but it’s freezing upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it ought 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, resulting in colder temperatures on the upper levels. It’s essential 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 critical role in disseminating conditioned air throughout different rooms of the building. However, issues with the ductwork can cause the upstairs being colder than the main level. A typical 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, causing 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 story or they are not correctly located, it can limit air circulation and cause inadequate 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 figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted HVAC pros like the team at Gopher Heating and Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing 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 ground level of your house, an HVAC zoning system could be a great solution.

An HVAC zoning system separates the household into distinct 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 effective in situations where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By installing a  zoning system, homeowners can control the temperature independently in each zone, allowing 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 challenge in multi-floor homes is when the upper floors are more humid than the lower level.

A frequent cause for excess upper floor humidity is weak ventilation on the upper floor, which can produce increased humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may permit warm, humid air from outside infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also create excessive moisture in that section of a home.

To address humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Proper insulation  in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Identifying 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 valuable tool to control humidity on the upper and lower floors.
