Myth: Closing vents in unused rooms saves energy
Closing vents in unused rooms is a common practice that many homeowners believe will save them money on energy bills. However, this is a misconception that can actually decrease the efficiency of your HVAC system and lead to increased costs. Here’s why closing vents in unused rooms doesn’t result in energy savings and can even be counterproductive.
The idea behind closing vents in unused rooms is that by reducing the area that needs to be heated or cooled, the HVAC system will work less and consume less energy. However, this logic overlooks the way HVAC systems are designed to operate. Central heating and cooling systems are engineered to distribute air evenly throughout the entire home. When vents are closed, the system continues to push the same amount of air, but it meets with increased pressure and resistance.
This increased pressure can lead to several issues. First, it forces the HVAC system to work harder to distribute air, which can lead to greater energy consumption and reduced efficiency. Second, the increased pressure can cause leaks in the ductwork, allowing conditioned air to escape into unconditioned spaces such as attics or crawlspaces. This not only wastes energy but also negatively impacts indoor air quality.
Closing vents can also create imbalances in the airflow throughout your home. This can result in some rooms becoming too warm or too cold, leading to discomfort for occupants and potentially causing the thermostat to be adjusted more frequently. This, in turn, can further increase energy consumption and costs.
- Increased Energy Consumption: Closing vents increases the pressure in the ductwork, making the HVAC system work harder and consume more energy.
- Potential Air Leaks: Increased pressure can cause conditioned air to leak out of cracks or gaps in the ductwork, wasting energy.
- Airflow Imbalances: Closing vents can lead to uneven heating or cooling, causing some rooms to be too hot or too cold.
- Reduced System Lifespan: Forcing the HVAC system to work harder can lead to increased wear and tear, potentially shortening its lifespan and leading to costly repairs.
Instead of closing vents, consider other HVAC tips to improve energy efficiency in your home. Proper insulation, regular maintenance of your HVAC system, and the use of programmable thermostats are effective ways to achieve energy savings without compromising the performance of your system. Additionally, keeping all vents open ensures optimal airflow and maintains the integrity of your HVAC system.
Incorporating smart home maintenance practices and being informed about common HVAC myths can help you make better decisions for your home’s heating and cooling needs. Don’t let the myth of closing vents in unused rooms cost you money—keep all vents open for a more efficient and comfortable home.
Myth: Setting your thermostat higher or lower doesn’t save energy
Many homeowners believe that setting their thermostat higher or lower when they’re not at home doesn’t save energy. This myth often leads to missed opportunities for significant energy savings. The truth is that adjusting your thermostat when you’re away or asleep can result in substantial reductions in your energy bills.
The misunderstanding often arises from the belief that the HVAC system has to work harder to return to a comfortable temperature after being set back, negating any potential savings. However, this is not the case. According to the Department of Energy, you can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for 8 hours a day from its normal setting. This is one of the most straightforward HVAC tips for achieving energy savings.
Here’s why this strategy works: The larger the difference between the indoor and outdoor temperatures, the more energy is used to maintain the indoor temperature. By adjusting the thermostat when you’re away or asleep, you reduce the amount of time your HVAC system spends maintaining a significant temperature difference, thereby saving energy.
To make the most of this HVAC tip, consider incorporating a programmable thermostat into your home maintenance routine. These devices can automatically adjust the temperature based on your schedule, ensuring that you’re not heating or cooling an empty home.

Moreover, proper use of a programmable thermostat can also extend the lifespan of your HVAC system. By reducing the amount of time the system spends running, you decrease wear and tear on its components. This can help prevent costly repairs and prolong the system’s overall lifespan.
It’s important to note that while adjusting the thermostat can lead to significant energy savings, it’s not the only factor to consider. Proper insulation, regular maintenance of your HVAC system, and addressing any air leaks are also crucial aspects of home maintenance that can enhance your energy-saving efforts.
Incorporating these practices into your routine can help you achieve a more efficient and comfortable home. Don’t let the myth about thermostat settings cost you money—take control of your energy usage and make informed decisions that benefit both your comfort and your wallet.
Myth: Fans cool the room even when you’re not there
Fans are a fantastic way to keep cool and improve air circulation in your home, but they don’t actually lower the temperature of a room; they simply create a wind chill effect that helps cool your skin. This common misunderstanding leads many people to believe that leaving fans running in empty rooms will help save energy by cooling the space. However, this is not the case and can even lead to unnecessary energy consumption.
Fans work by evaporating sweat from your skin, making you feel cooler. When you are not present, the fan does not provide any cooling benefit because it cannot lower the room’s temperature. Therefore, leaving a fan on in an unoccupied room doesn’t contribute to energy savings; instead, it results in wasted electricity.
Additionally, fans consume energy while operating. Although they are generally more energy-efficient than air conditioning units, running fans in empty rooms adds to your electricity bill without providing any real cooling effects or energy savings. This is one of the simplest yet often overlooked HVAC tips for reducing energy consumption and maintaining an efficient home.
Understanding this myth can help you make more informed decisions regarding your home maintenance routine.
