How to Increase Airflow to a Second Floor

Are you concerned about uneven temperatures in your house? If you have a two-story home and want to know how to increase airflow to the second floor, then you’ve come to the right place. We’ll walk you through easy steps to upgrade your air circulation, so you can enjoy a more comfortable temperature on every level in your home.

Quick Summary

  Maximizing Airflow to a Second Floor: A Step-by-Step Guide

Increasing airflow to a second floor can be done in several different ways. One of the most effective ways to do so is by installing vents and exhausts and focusing on both ventilation and insulation.

When installing vents, look for spaces in the eaves, gables, and eaves that are big enough to accommodate an exhaust fan. These fans will help pull hot, stale air from the top floor of your home and circulate fresh air. Additionally, consider installing air conditioning vents in the attic, to help move hot air up and out.

Adequate insulation is important for improving airflow, as well. Heat tends to rise, so make sure your home’s attic is insulated properly. This will also help prevent hot air and moisture from getting into your second-floor living spaces. Consider investing in an air infiltration system and zone dampers, as well.

Finally, use your windows. On warm, sunny days, open up your windows to bring fresh air into your home in a process called cross-ventilation. To increase airflow even further, install ceiling fans or a whole-house fan to help move air throughout your spaces.

Maximizing Airflow to a Second Floor: A Step-by-Step Guide

Do you ever feel as if your entire second floor is a sauna? If you’re noticing that your second floor is too hot, you may need to maximize the airflow. To do this, you’ll want to create pressure differences between your upper and lower level. Here’s a step-by-step guide to help you increase your second floor’s airflow and the comfort level of your home.

1. Install Additional Vents & Fans

If you find that you’re lacking airflow in the second floor, start by installing additional vents and fans. You can find many types of fans that can be conveniently installed higher up on your second floor. Consider using energy-efficient fans that come with multiple speeds to give you full control over your cooling needs.

2. Consider Adding a Dehumidifier

Dehumidifiers do more than just reduce the humidity in your home. They also help to keep the temperature comfortable. This way, you won’t feel so stuffy while relaxing or sleeping in the second floor. Make sure that you use a dehumidifier that keeps the humidity at a comfortable level.

3. Manage Existing Vents & Fans

Inspect the vents and fans that are already installed on the second floor. If you find that any of them aren’t working properly, then have them serviced immediately. You can also adjust their speeds as needed. For example, during the summer season, you may want to raise their speed to provide cooler air.

4. Purchase Smart Thermostats

You’ll want to maintain consistent temperatures across different floors in your home. Smart thermostats are the perfect way to do this. Set them to run your HVAC on a schedule that will regulate the temperature between floors. This will allow you to balance your home’s temperature easily.

5. Move Furniture Away From Vents

On occasion, furniture may be placed directly in front of a vent. This can potentially block the airflow and restrict the temperature variations between floors. Moving furniture away from vents and fans can help keep the air flowing towards the second floor.

6. Insulate Hot Zones

Insulate any areas on your second floor that may get too warm. This may include the attic, ceilings, & walls. Include a high-performance insulation material and keep it properly sealed to maximize the air exchange. You’ll also want to investigate if any areas are causing air leaks, as this could be a main cause of heat gain in the second floor.

7. Install an Air Curtain

If your upper level is still not getting enough airflow, consider installing an air guard at the closest exit to the second floor. Air curtains are powerful fans that are installed below any potential entry points. This will help to keep the cool air in, and the hot air out, while providing consistent temperatures in your home.


Maximizing the airflow to your second floor doesn’t have to be difficult or expensive. With the right tips, you can quickly and efficiently increase the airflow and reduce the temperature in your home.

Personal Experience

How can I force more heat upstairs?

Increasing the airflow to a second floor can help reduce stale air and maintain comfortable temperatures throughout the home. The best way to achieve this is to install a powerful exhaust fan in the upper level of the home and make sure the fan is vented to the outside. Exhaust fans should always be vented to the outside to ensure proper air flow and reduce the risk of moisture buildup.

When installing the fan, keep in mind the design of the home. Homes with large open areas, such as loft-style homes, can benefit from an exhaust fan that is mounted in the ceiling or into a wall. This will help evenly distribute the airflow throughout the home. In addition, large homes with multiple bathrooms should consider installing a central exhaust fan, as this will streamline the airflow process and not rely on individual fan power.

When it comes to ventilation, the more air being exchanged the better. Consider installing vents in other locations such as hallways, stairwells, and windows. These vents will help to pull stale air and stagnant air out of the home while replacing it with fresh air from the outside. This is especially useful in cases where the fan may not be powerful enough to provide the desired air flow.

Lastly, make sure to regularly maintain the fan and the associated duct work. Dust, dirt, and other contiminants can clog the ducts and reduce the airflow, so keep the fan and all connected areas clean for optimal performance. By following these steps and regular maintenance, it should be relatively easy to increase the airflow to your second floor.

Frequently Asked Questions

How can I force more heat upstairs?

To force more heat upstairs, open all upstairs vents and doors. This will allow the hot air to flow freely throughout the rooms and reach all the vents. Additionally, adjust the thermostat to pump more heat into the upstairs area.

How do you cool a second story?

sunny days, keep drapes and blinds closed to reduce the amount of sunlight that enters the second story. Use fans. Install ceiling fans to help circulate cooled air from the lower levels throughout the second story. Place fans strategically in areas that maximize air flow. Invest in an air conditioning unit. Portable air conditioners are an affordable and effective way to cool a second story.

How do you get air on top of floor?

The best way to get air on the top floor of a building is to install an HVAC system. These systems use a series of fans and ducts to push air up through the levels of the building. Additionally, you can open windows on the lower floors and use fans to push air to the upper levels. Finally, natural air circulation and air conditioning can help to circulate air from the lower levels to the top.

How do you identify a supply duct?

To identify a supply duct, feel for a steady stream of air blowing out of the vent. If it is a supply vent, the air should feel directed, creating a suction-like effect. Place your hand or a piece of paper near the vents to test and verify that it is supplying air.

How do you know which ducts are supply and return?

To identify which ducts are supply and return, check the size and airflow direction. Supply vents are typically smaller and draw air in towards the duct, whereas return vents are usually larger and force air outwards. Additionally, you can hold a piece of paper up to the duct to test the airflow and determine which type of vent it is.

How do I find air ducts in my house?

To find air ducts in your house, first check the walls, floor, and ceilings of rooms. Take note of any vents or grates, as these will often indicate that an air duct is somewhere in the vicinity.
