Every floor in your home should be a refuge 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 simply be because most thermostats in a house are on the main floor, which is where people spend the most 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 caused by problems with your HVAC system. Some of these issues can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the specialists at Western Mechanical, Inc. will help you figure out 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 becoming 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 ground 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 air conditioner is not big enough to cool the entire home, causing it to have difficulty cooling the upstairs sufficiently.
To tackle these issues, homeowners could put in more insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the AC is the right size for the home, call an experienced HVAC company like Western Mechanical, Inc. inspect the unit. A skilled 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 So Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that could result in a frosty night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to leak 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 thick, 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 rooms of the building. However, problems with the ductwork can result in the upstairs being colder than the downstairs. A typical explanation for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, causing 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 potential problem area in 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 restrict air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can lead to air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced HVAC pros like the team at Western Mechanical, Inc. to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help improve 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 home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system breaks the household into distinct 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 useful in scenarios where the upstairs of a multi-story home is too hot or really cold while the main floor is comfortable. By installing a zoning system, homeowners can regulate the temperature independently in each zone, making it possible for them to address specific hot or cold spots effectively.

Why Is My Upstairs So Humid?
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 higher levels are more humid than downstairs.
A common reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in higher 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 infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems 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. Adding more insulation in the attic and better sealing the attic and walls can help protect against 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 helpful tool to reduce humidity on the upper and lower floors.
