In Burleson, where summers routinely hit the high 90s or more, your air conditioning system becomes one of the most important systems in your home. But even the best equipment can struggle when it’s not used or maintained properly. Many common AC problems can be traced back to homeowner habits that seem harmless but cause long-term damage or reduce efficiency.


In this article, we’ll cover five of the most common air conditioning mistakes made by homeowners in Burleson, how they affect your system, and what you can do instead to ensure comfort, efficiency, and system longevity.


Mistake #1: Ignoring Regular Filter Changes


Neglecting to change your air filter is one of the simplest yet most damaging AC mistakes. A clogged filter restricts airflow, making your system work harder to push air through your home. This leads to:


  • Higher energy bills

  • Reduced cooling performance

  • Overheating and short cycling

  • Dirty coils and system strain

What to Do:


  • Change standard filters every 30 to 90 days

  • Replace more often if you have pets, allergies, or live in a dusty area

  • Set reminders or subscribe to filter delivery services for consistency

This is a low-cost step that makes a big difference in comfort and equipment life.


Mistake #2: Setting the Thermostat Too Low


It’s tempting to crank the thermostat down to 68°F on a sweltering Burleson day, but setting your thermostat too low won’t cool your home faster. It just forces the system to run longer, using more energy and increasing wear.


Consequences:


  • Wasted electricity

  • Increased utility costs

  • Shortened equipment lifespan

What to Do:


  • Set your thermostat to 76°F to 78°F while you're home

  • Use ceiling fans to help circulate air and create a cooling effect

  • Program your thermostat to adjust when you’re away or asleep

Consider upgrading to a smart thermostat to help manage temperature automatically and maximize efficiency.


Mistake #3: Skipping Annual Maintenance


Many homeowners wait until something goes wrong before calling an HVAC technician. By then, small problems have often turned into big ones.


Risks of Skipping Maintenance:


  • Reduced system efficiency

  • Unnecessary repairs and early breakdowns

  • Missed safety issues or refrigerant leaks

  • Voided manufacturer warranties

What to Do:


  • Schedule a professional AC tune-up every spring

  • Ask about maintenance plans that include priority service and seasonal checkups

Mistake #4: Blocking or Closing Vents


Some homeowners try to “redirect” airflow by closing vents in unused rooms or placing furniture in front of return vents. Unfortunately, this often backfires.


Why It’s a Problem:


  • Increases system pressure, leading to duct leaks or blower strain

  • Disrupts airflow balance

  • Can cause coils to freeze due to restricted circulation

What to Do:


  • Keep all vents open and unobstructed

  • Use zoning or ductless mini-split systems if you want room-specific control


  • Make sure return air grilles have plenty of clearance for airflow

Good airflow keeps your system balanced and your home consistently comfortable.


Mistake #5: Delaying Repairs or Ignoring Warning Signs


Strange sounds, bad smells, and short cycling are signs something’s wrong. Waiting too long to address them can lead to full system breakdowns and higher repair costs.


Common Warning Signs:


  • Buzzing, grinding, or rattling noises

  • AC blowing warm or inconsistent air

  • Unusual odors when the system runs

  • Short cycling (system turns on and off quickly)

  • Water pooling near the indoor unit

What to Do:


  • Call a licensed HVAC professional at the first sign of trouble

  • Address small issues early to avoid major repairs later

  • Don’t wait for total failure, especially during peak summer months

Frequently Asked Questions


Does setting the thermostat lower cool the house faster?


No. Air conditioners cool at a consistent rate. Lowering the thermostat only makes the system run longer, not faster.


How often should I service my AC in Burleson?


At least once per year—preferably in the spring, before summer temperatures hit. Systems that run year-round may need biannual service.


Can closing vents help redirect airflow?


Not effectively. It increases pressure in your duct system and can lead to damage. Use zoning or dampers for targeted temperature control instead.


What’s the best temperature to set the thermostat in summer?


The Department of Energy recommends 78°F when home and 82°F when away for optimal efficiency and comfort in Texas.


What happens if I don’t change my AC filter?


Your system can overheat, freeze, or shut down due to airflow restriction. It will also use more energy and wear out faster.
