Common Myths About HVAC Systems


The HVAC system is an indispensable tool in our homes, providing a comfortable indoor environment that suits our needs all year round. However, with any widespread technology, there are bound to be myths and misconceptions associated with it. Many of these are baseless and can lead homeowners to make costly mistakes during installation and maintenance.

Myth #1: Closing Vents in Unused Rooms Saves Energy

Many homeowners believe that closing vents in rooms they are not using will save energy and money, but the truth is that this is a myth. HVAC systems are designed to evenly distribute conditioned air throughout the entire duct system. Closing vents on one side will obstruct the system's airflow and, ultimately, make it work harder to balance the air pressure. This increased effort can even cause damage to your HVAC system, mainly if it is an older model. Instead, consider using a zoning system or programmable thermostat to regulate temperature and save on energy bills.

Myth #2: Bigger HVAC System is Better

A common misconception is that a bigger HVAC system is better at maintaining a comfortable indoor environment. The truth is that an oversized unit will lead to short cycling, resulting in more energy consumption and higher utility bills. Additionally, the HVAC system will not operate at optimum efficiency if it is too large for the space it serves, leading to premature wear and tear of system components and a reduced system life span. Always consult with an HVAC contractor before choosing any system size.

Myth #3: Changing the Air Filter Once a Year is Enough

Air filters are a crucial component of your HVAC system, trapping dust, debris, and other particles and preventing them from circulating in your home's air. Many homeowners believe that an air filter only needs to be changed once per year, but this could not be further from the truth. The air filter should be checked and replaced every one to three months, depending on the filter's type and household conditions. A dirty filter will reduce the airflow and lead to icing on the evaporator coil, significantly affecting your system's performance and efficiency.

Myth #4: Installing HVAC System is a DIY Project

While installing an HVAC system yourself may be tempting, it's not advisable. Installing HVAC systems requires specialized knowledge that only a qualified HVAC professional possesses. A DIY installation can result in injury, damage to property, or cause system failure, leading to more significant expense in repair or replacement. Besides, improperly installed HVAC systems can reduce efficiency and performance, compromising indoor air quality.

Myth #5: Turning Up the Thermostat Cools Your Home Faster

Many homeowners believe that turning up the thermostat sets the air conditioning system to cool their homes faster. But this is just a myth. HVAC systems are designed to work at a specific rate, and turning the thermostat will not speed up this process. It will make it work longer and harder to reach the desired temperature, leading to higher energy consumption. The best way to achieve your desired temperature is to set the thermostat at a comfortable temperature.
