Common HVAC Myths Debunked

Myth 1: Closing Vents in Unused Rooms Saves Energy

Reality: Closing vents can actually harm your HVAC system by causing pressure imbalances, leading to inefficiency and potential damage. It's better to keep all vents open for optimal airflow.

Myth 2: Bigger HVAC Systems are Always Better

Reality: An oversized system can lead to frequent cycling, inefficient operation, and higher energy costs. Properly sizing your HVAC system ensures balanced performance and comfort.

Myth 3: You Only Need to Change the Filter Once a Year

Reality: Filters should be checked monthly and typically replaced every 1-3 months, depending on usage and filter type. Regular replacement ensures optimal airflow and system efficiency.

Myth 4: Thermostats Should Be Set High for Quick Heating and Low for Quick Cooling

Reality: Thermostats control the set point, not the speed of heating or cooling. Setting extreme temperatures doesn't speed up the process and can increase energy usage.

Myth 5: Maintenance Isn’t Necessary for New Systems

Reality: Regular maintenance is crucial for all HVAC systems, new or old. Preventive care helps identify issues early, ensuring longevity and efficient operation.

Myth 6: Fans Help Cool the Room

Reality: Fans cool people, not rooms. They create a wind-chill effect, making you feel cooler, but they don't lower the room temperature. Turn them off when you leave to save energy.

Myth 7: Duct Tape is Ideal for Sealing Ducts

Reality: Despite its name, duct tape isn't suitable for sealing ducts due to its tendency to degrade over time. Use mastic sealant or HVAC-specific foil tape for proper sealing.

Myth 8: Maintenance is Unnecessary for a System That’s Working Fine

Reality: Regular maintenance prevents unexpected breakdowns, improves efficiency, and extends the life of your HVAC system. Ignoring it can lead to costly repairs and replacements.

Myth 9: All HVAC Filters are the Same

Reality: Filters vary in quality and efficiency. Choosing the right filter depends on your system and specific needs, such as allergen reduction or dust control. Consult your HVAC professional for recommendations.

Myth 10: Setting the Thermostat to a Very Low Temperature Cools the Home Faster

Reality: HVAC systems work at a consistent rate. Setting the thermostat extremely low won't cool your home faster; it will just overwork the system, increasing energy consumption.
