Why Is It So Hot Upstairs? Tips for Keeping Your Upstairs As Cool As Your Downstairs

In the summer, it’s common for the upper level of a two-story home to feel much warmer than the lower level, even with air conditioning in operation. HB Home Service Team provides AC installation, maintenance and repair services — with additional emergency services and duct cleaning.

Why Is My Upstairs So Hot in Summer?

Many homeowners experience this frustrating issue, especially during the summer months. The primary reason for this discomfort is that heat naturally rises, accumulating in the upper levels of your home. Other factors, such as poor insulation and inadequate airflow, can exacerbate the situation.

The Mechanics of Forced-Air HVAC Systems

Below are some straightforward adjustments you can make. However, if you’re unsure or prefer professional assistance, reach out to one of our experts. 

Here are some effective strategies to consider:

• Adjust your dampers: You can adjust your dampers if there are dials or levers on your vents — this will help control the airflow. These are small louvers that open and close to regulate air movement. To cool the upper floors more effectively during the summer, keep your second-floor dampers fully open while partially closing the ones on your first floor. This will direct more cool air to the warmer upstairs areas.
• Open upper return vents: For homes with a top/bottom return vent system, open the upper vents during summer. This allows the HVAC system to get air from higher points where warmer air tends to accumulate. In winter, close the upper vents to help retain the warm air.
• Use ceiling fans wisely: Ceiling fans improve the comfort and performance of your AC. In the summer, set your fan to rotate counterclockwise. This direction pushes cool air downward, creating a refreshing breeze that helps you feel cooler without overworking your AC.
• Block sunlight with curtains and blinds: During the day, especially on second floors, pull down blinds and close curtains to shield your home from direct sunlight. This simple step can significantly lower indoor temperatures and reduce the workload on your air conditioning system. 
• Restrict airflow in winter: If your downstairs is colder than your upstairs during the winter, restrict the airflow upstairs and fully open the vents on the first floor to force more warm air downstairs.
• Upgrade your HVAC system: Trouble maintaining consistent temperature across rooms may signal a failing system. Consult a professional to assess if your current HVAC unit is sufficient for your property — we will consider your home size, types of systems based on your home’s design, energy efficiency ratings and budget considerations. HB Home Service Team offers local, customized AC replacement and installations and post-installation testing — with minimal disruption to your daily life. 

Addressing the Cold Basement/Hot Upstairs Scenario

If you’ve made all these adjustments yet still find your home uncomfortable, the AC system may be improperly sized for your space. An undersized unit will run continuously, leading to longer cycles, while an oversized unit will cycle on and off frequently, which can strain the motor and cause premature burnout.

Both scenarios can lead to increased energy costs and more frequent repairs. If you suspect your system isn’t the right size, it’s best to contact a reliable HVAC technician for a thorough assessment.

Regular Air Conditioning Maintenance

Make sure to keep up with regular professional HVAC maintenance on your system. Change air filters monthly or as needed, clean your condenser coils and schedule professional tuneups. A well-maintained system will operate more efficiently and effectively.
