As a homeowner in Decatur, AL, you’ve likely heard various tips and tricks about maintaining your HVAC system. But how many of these are actually true? At Southeastern Mechanical Services, we often encounter misconceptions that can lead to inefficient operation, unnecessary expenses, and even system damage. Today, we’re setting the record straight by debunking some common HVAC myths. Let’s dive in and separate fact from fiction!

Myth 1: Closing Vents in Unused Rooms Saves Energy

The Fiction: Many homeowners believe that closing vents in unused rooms will redirect air to other areas of the house, saving energy and money.

The Fact: Closing vents can actually increase pressure in your ductwork, forcing your HVAC system to work harder. This can lead to:

  • Increased energy consumption
  • Potential damage to your ductwork
  • Uneven heating and cooling throughout your home

Instead of closing vents, consider HVAC zoning if you frequently have unused spaces. This allows for more efficient, targeted heating and cooling.

Myth 2: The Bigger the HVAC System, the Better

The Fiction: A larger HVAC system will cool or heat your home faster and more efficiently.

The Fact: When it comes to HVAC systems, bigger isn’t always better. An oversized system can lead to:

  • Short cycling, which reduces efficiency and increases wear and tear
  • Inadequate dehumidification, especially important in Decatur’s humid climate
  • Higher energy bills due to inefficient operation

Proper sizing is crucial for optimal performance. Our expert technicians can help determine the right size system for your Decatur home.

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

The Fiction: Changing your air filter annually is sufficient for maintaining your HVAC system.

The Fact: The frequency of air filter changes depends on various factors, including:

  • The type of filter you use
  • The number of occupants and pets in your home
  • The air quality in your area

In general, we recommend checking your filter monthly and changing it at least every 3 months. During high-use seasons or if you have pets, you may need to change it more frequently.

Myth 4: Setting Your Thermostat Lower Will Cool Your Home Faster

The Fiction: Cranking your thermostat to a very low temperature will cool your home more quickly.

The Fact: Your HVAC system cools at the same rate regardless of the temperature setting. Setting your thermostat extremely low will:

  • Not cool your home any faster
  • Potentially cause your system to run longer than necessary, wasting energy
  • Lead to an uncomfortably cold home if you forget to adjust it back

Instead, use a programmable or smart thermostat to set efficient, consistent temperatures.

Myth 5: Maintenance Is Only Necessary When Your System Breaks Down

The Fiction: HVAC systems only need attention when they stop working.

The Fact: Regular maintenance is crucial for:

  • Preventing unexpected breakdowns
  • Maintaining energy efficiency
  • Extending the lifespan of your system
  • Ensuring consistent performance, especially during Decatur’s hot summers and cool winters

We recommend scheduling professional maintenance at least twice a year – typically in spring and fall.

Myth 6: Ceiling Fans Cool a Room

The Fiction: Running ceiling fans will lower the temperature in a room.

The Fact: Ceiling fans don’t actually cool the air; they create a wind-chill effect that makes you feel cooler. They’re great for:

  • Improving comfort when you’re in the room
  • Allowing you to set your thermostat a few degrees higher without sacrificing comfort

Remember to turn fans off when you leave the room to save energy.

Myth 7: HVAC Systems Don’t Affect Indoor Air Quality

The Fiction: HVAC systems are only for heating and cooling, not for air quality.

The Fact: Your HVAC system plays a significant role in your home’s air quality. It can:

  • Filter out pollutants and allergens
  • Help control humidity levels
  • Circulate and freshen air throughout your home

Investing in regular maintenance and high-quality filters can significantly improve your indoor air quality.
