AC Myths Busted: What Actually Keeps Your Fort Worth Home Cool

With Fort Worth summers in full swing, there’s no shortage of advice about keeping your home cool. But not all of it is accurate. Believing AC myths can lead to higher energy bills, reduced comfort, and unnecessary wear on your system.

Here’s what you need to know to separate fact from fiction.

Myth 1: “Keeping the AC on All Day Saves Energy”

Many homeowners think leaving the AC running constantly is more efficient than turning it off. The truth:

  • Your system works harder and consumes more energy running constantly
  • Using a programmable thermostat allows your AC to cool only when needed
  • Short-term adjustments, like raising the temperature while away, save energy

Fact: Controlled use of your AC with smart scheduling keeps you comfortable and reduces costs.

Myth 2: “Bigger AC Units Cool Better”

Bigger isn’t always better. Oversized systems can:

  • Short-cycle, turning on and off frequently
  • Fail to properly dehumidify the air
  • Wear out components faster due to uneven operation

Fact: Correctly sized AC units maintain temperature efficiently and handle humidity better.

Myth 3: “Closing Vents in Unused Rooms Saves Money”

It seems logical, but closing vents can actually:

  • Increase pressure in ductwork
  • Cause leaks and reduced airflow
  • Make the system work harder in other parts of the home

Fact: Keep vents open and manage airflow with a balanced system. Consider zoning solutions if you want separate temperature control.

Myth 4: “Fan Speed Doesn’t Matter”

Fans play a big role in comfort and efficiency:

  • Ceiling fans should spin counterclockwise in summer to create a cooling breeze
  • Use fans to complement the AC, not replace it entirely
  • Turn off fans when rooms are empty—fans cool people, not spaces

Fact: Proper fan use helps your home feel cooler without overworking the AC.

Myth 5: “Maintenance Isn’t Important if the AC Runs”

Even if your AC seems fine, skipping maintenance can lead to:

  • Reduced efficiency and higher bills
  • System breakdowns during peak heat
  • Shortened lifespan of the unit

Fact: Regular maintenance, like filter changes and professional inspections, ensures consistent cooling and energy savings.

Final Thoughts

Don’t fall for common AC myths. Understanding how your system actually works helps you stay comfortable, save money, and extend the life of your AC during Fort Worth’s hottest months.

Focus on correct use, proper maintenance, and smart cooling strategies to keep your home efficiently cool all summer.
