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

This could just be because 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 discrepancies between the upstairs and downstairs could also be because of issues with your HVAC system. Some of these difficulties can be sorted out relatively quickly while others might call for more extensive and costly fixes. Here, the specialists at All Weather Heating & Air Conditioning Inc will help you determine 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 natural for the second floor of a home to get hotter than the main floor. Not enough 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 air conditioner is not powerful 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 sufficient ventilation. If there’s a question of whether the air conditioning unit is the correct size for the home, call an experienced HVAC company like All Weather Heating & Air Conditioning Inc inspect the unit. A qualified professional also can help find 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 very cold upstairs, that could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent explanations for 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, causing 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 adequate insulation in the walls to keep the cold out and the heat inside.

The ductwork in a home plays a very important role in circulating conditioned air throughout different rooms of the building. However, problems with the ductwork can contribute to the upstairs being colder than the main level. A typical cause for this is improper airflow balance. The ducts may not be the proper size or configuration, which results in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, which creates 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 placed, it can restrict air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can allow 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 trusted experts like the team at All Weather Heating & Air Conditioning Inc to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help increase airflow and ensure a more even 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 ground level of your house, an HVAC zoning system could be an effective solution.

An HVAC zoning system breaks the residence 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 useful in situations 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 effortlessly.

Why Is the Humidity So High 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 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, inadequate insulation or sealing in the attic or walls may allow warm, humid air from outside infiltrate the upstairs rooms. And, 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 address humidity problems, homeowners can add more ventilation by getting fans or opening windows to promote airflow. Adding more insulation  in the attic and better sealing the attic and walls can help prevent external moisture from entering the upstairs. Locating 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 helpful tool to reduce humidity on the upper and lower floors.
