Common Myths About HVAC Systems

The HVAC system is essential for keeping your home comfortable year-round, but many myths about heating and cooling systems could cost you money and efficiency. Here, we debunk some of the most common misconceptions to help you make informed decisions and get the most out of your HVAC system.

Myth #1: Bigger Systems Are Better

Many people assume that a larger HVAC system will heat or cool their homes more effectively. However, an oversized system can lead to uneven temperature control and increased wear and tear. HVAC systems are designed to suit specific home sizes and layouts. An oversized system will turn on and off frequently, causing unnecessary strain on the equipment and wasting energy. It’s best to have a professional assess your home’s needs to recommend a system that fits your space perfectly.

Myth #2: Closing Vents in Unused Rooms Saves Energy

It seems logical to close off vents in rooms you’re not using, but this can actually harm your HVAC system. Closing vents disrupts the airflow balance, forcing your system to work harder and potentially leading to duct leaks. Rather than saving energy, this can increase your utility bills and wear down your system prematurely. Instead, consider zoning options or a programmable thermostat to control the temperature in different areas more effectively.

Myth #3: HVAC Systems Only Need Maintenance When There's a Problem

Waiting until there’s a noticeable problem with your HVAC system can result in costly repairs. Regular maintenance keeps your system running efficiently and catches minor issues before they become major. Routine check-ups can improve performance, extend the lifespan of your equipment, and ensure you’re getting the most energy-efficient operation possible.

Myth #4: Thermostat Placement Doesn’t Matter

The placement of your thermostat plays a big role in your HVAC system’s efficiency. Placing a thermostat near heat sources, such as appliances or windows with direct sunlight, can cause it to misread the home’s temperature and cycle the system incorrectly. To avoid this, install the thermostat in a central location, away from heat sources, for accurate readings and improved performance.

Myth #5: You Can Use Any Filter in Your System

All filters are not created equal. Choosing the right filter for your system is essential to ensure optimal airflow and effective filtration. Using a filter with too high a rating may restrict airflow, causing the system to work harder, while using a filter with a low rating may not provide sufficient air quality. It’s important to check your system’s specifications or consult a professional to choose the best filter for your HVAC system.

Myth #6: Cranking Up the Thermostat Heats Your Home Faster

Turning your thermostat up higher than your desired temperature won’t heat your home faster—it just makes the system run longer. Modern HVAC systems heat and cool at a constant rate, so setting the thermostat to your preferred temperature is the most efficient way to reach and maintain comfort.

Key Takeaways for Better HVAC Efficiency:

  • Right Sizing: Choose an HVAC system that fits your home’s size and needs.
  • Ventilation Matters: Keep all vents open and use zoning for temperature control.
  • Routine Maintenance: Schedule regular maintenance to prevent issues.
  • Thermostat Location: Install your thermostat away from heat sources.
  • Filter Selection: Use the correct filter for your HVAC system’s requirements.
  • Thermostat Settings: Set it and forget it—don’t crank the temperature up or down.
