Your entire residence should be a refuge that’s warm and toasty in the cold months and cool and comfortable in the summer. However, families who live in some two-story homes find the upper floor is stubbornly hotter or colder than the main 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 the majority 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 discrepancies between the upstairs and downstairs could also be due to problems with your HVAC system. Some of these challenges can be resolved relatively quickly while others might necessitate more extensive and costly fixes. Here, the team at Speedy Air Conditioning will help you solve 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 chalked up 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 make this worse by permitting heat transfer from the roof into the upstairs rooms.

Another common reason is that the air conditioning is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.

To deal with these issues, homeowners could put in additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the AC is the correct size for the home, call an experienced HVAC company like Speedy Air Conditioning inspect the unit. A skilled professional also can help find a unit that's better suited for your home if you require 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 very chilly night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it is supposed to are the insulation levels and the ductwork.

Inadequate insulation enables cold air to filter through the home’s attic or walls and contribute to heat loss, creating 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 proper insulation in the walls to keep the cold out and the heat inside.

The ductwork in a home plays a fundamental role in distributing 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 design, 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 placement of the supply and return vents. If there are fewer vents on the upper level or they are poorly installed, it can limit air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and making the temperature difference more pronounced.

To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by experienced HVAC pros like the team at Speedy Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help improve airflow and ensure a more consistent 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 ground level of your house, an HVAC zoning system could be a highly effective solution.

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

This system can be very beneficial in scenarios where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By installing a  zoning system, homeowners can control the temperature independently in each zone, making it possible for them to address specific hot or cold spots easily.

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 upstairs is more humid than the lower level.

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

To manage humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Proper insulation  in the attic and better sealing the attic and walls can help stop 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 valuable tool to reduce humidity in your home.
