This article will debunk some of the most prevalent HVAC myths and shed light on the facts every homeowner should know.
6 Common HVAC Myths That We’ve Debunked
So, let’s jump into the most common myths surrounding air quality and HVAC units in your home.
1. Closing Vents Saves Energy
One of the most persistent myths is that closing vents in unused rooms can save energy and lower utility bills. The idea behind this myth seems logical: if the air isn’t directed into a room, it won’t need to be heated or cooled.
However, modern HVAC systems are designed to operate optimally with a balanced airflow. Closing vents disrupt this balance, causing pressure imbalances and potentially reducing efficiency and higher energy consumption. It can also strain the HVAC system, increasing wear and tear over time.
2. Lowering the Thermostat Temperature Cools the Room Faster
Some believe cranking the thermostat to an extremely low temperature will cool the room faster. In reality, the HVAC system operates at a consistent pace, regardless of the desired temperature.
Setting the thermostat to a lower temperature than needed only results in excessive cooling, wasting energy, and making the room uncomfortable. It’s best to set the thermostat to the desired temperature and allow the HVAC system to work efficiently.
3. Regularly Changing the Air Filter is Unnecessary
Some homeowners overlook the importance of regularly changing their HVAC system’s air filters. However, a dirty air filter can lead to a host of problems. It restricts airflow, making the HVAC system work harder to maintain the desired temperature.
Moreover, a clogged filter allows dust, debris, and allergens to circulate, potentially causing respiratory issues. To ensure optimal HVAC performance and indoor air quality, change the air filters as the manufacturer recommends.
4. Ceiling Fans Cool the Room
Ceiling fans create a wind-chill effect, making you feel calmer when the air moves across your skin. However, it’s crucial to understand that ceiling fans do not lower the room’s temperature.
Leaving a ceiling fan on in an unoccupied room doesn’t have a cooling effect, so remember to turn them off when you leave.
5. HVAC Maintenance is Optional
Some homeowners believe that HVAC maintenance is an unnecessary expense and only needed when the system malfunctions. However, regular maintenance is crucial for the longevity and efficiency of your HVAC system.
Professional HVAC technicians can identify and fix minor issues before they become major, costly problems. Routine maintenance can significantly improve the system’s performance and help avoid unexpected breakdowns.
6. HVAC Systems Don’t Need Upgrading
Many people think that once they have installed an HVAC system, it will work flawlessly for a lifetime without any upgrades. However, HVAC technology is constantly advancing, and newer systems are more energy-efficient and capable of providing better indoor comfort.
If your HVAC system is over 10-15 years old, upgrading to a more unique, energy-efficient model can lead to substantial energy savings and improved performance.
