Understanding AC Malfunctions: Causes, Solutions, and When to Call for Repair


Hey there! If you’ve ever dealt with an air conditioner that’s just not cutting it on a hot Kansas City day, you know how frustrating it can be. Here at Better Service Inc., we get it. Your AC is crucial for maintaining a comfortable home or workspace, especially when temperatures soar to 90 degrees or higher. So, let’s dive into the common reasons your AC might not be cooling, what those weird noises mean, and when it’s time to call in the pros!

Common Reasons Why Your AC Isn’t Cooling Properly

Your air conditioner is working, but something's off. Maybe the air isn’t as cold as it should be, or you’ve noticed some rooms are warmer than others. Here are some of the most common culprits behind an underperforming AC:

  • Dirty Cooling Coils: Indoor and outdoor coils can accumulate dirt, making it harder for your system to transfer heat effectively.

  • Refrigerant Leak: If the refrigerant is leaking, your AC will struggle to move heat out of your house, leaving you sweltering inside.

  • Blocked Condenser Unit: Outdoor units often get blocked by leaves, plants, or other debris, restricting airflow and heat release.

  • Dirty Air Filter: A clogged filter reduces airflow, preventing warm air from cooling down as it passes through your AC.

  • Compressor Problems: The compressor is the heart of your AC system. If it starts to fail, your air conditioner can’t effectively cool your home.

  • Aging System: Sometimes, your AC is simply past its prime. Old systems naturally lose efficiency and cooling power over time.

  • Improper Thermostat Settings: A thermostat set to “on” instead of “auto” might circulate warm air when the cooling cycle isn’t active.

Understanding AC Noises and What They Indicate

Loud, unusual noises coming from your AC can be alarming, but they’re also a helpful warning sign. Here’s a quick breakdown of what those sounds might mean:

  • Banging Noises: Often indicate a defective compressor or fan motor.

  • Whistling or Hissing: Could signal a refrigerant leak, which needs immediate attention.

  • Rattling: Might be caused by loose mechanical components, like fan blades or screws.

  • Squealing: Could point to a misaligned fan belt or broken motor bearings.

Noisy ACs are trying to tell you something’s up, so don’t ignore them! It’s best to get these issues checked by a professional.

Key Signs You Need Professional AC Repair Services

Sometimes, the signs of a malfunctioning AC are more subtle than noise. Here’s what to watch out for:

  • Your home feels more humid than usual.

  • The air coming from your vents isn’t as cold as it used to be.

  • You notice a decrease in airflow.

  • Your AC’s coils are freezing up.

  • There’s a foul odor coming from the system.

  • Temperature varies significantly from room to room.

If any of these issues sound familiar, it’s time to reach out for some professional help.

Why Timely AC Repair is Essential

Addressing AC problems as soon as they arise isn’t just about comfort—it’s about saving money and extending your system’s life. Here’s why acting fast is crucial:

  • Restoring Comfort: You want to keep your home or business cool and comfortable during those scorching summer days.

  • Ensuring Health and Safety: A malfunctioning AC can lead to poor indoor air quality, affecting your health.

  • Improving Energy Efficiency: Quick repairs prevent your system from working harder than necessary, keeping energy bills in check.

  • Preventive Maintenance: Fixing small issues now avoids bigger, costlier problems later.

  • Avoiding Business Disruptions: For commercial spaces, prompt repairs keep operations running smoothly without impacting productivity.

Preventive Measures: Keeping Your AC Running Efficiently

The best way to avoid most AC problems is to schedule  regular maintenance. Here at Better Service Inc., we recommend an annual AC tune-up that includes a thorough inspection and cleaning. Here’s what we cover during a tune-up:
