As temperatures rise in Carmel, Indiana, ensuring your air conditioning system is running smoothly is critical to staying comfortable and avoiding mid-summer breakdowns. At Geotane Property Management, we understand how a faulty AC unit can lead to tenant complaints, higher utility bills, and costly emergency repairs. Before the summer rush hits, keep an eye out for these 5 early warning signs your AC might need repair—and learn what steps you can take now to prevent major issues later.
1. ❄️ Warm Air Blowing From Vents

If your AC is blowing warm or room-temperature air, something isn’t working properly. Possible causes include:
- Low refrigerant levels
- A malfunctioning compressor
- Thermostat issues
Pro Tip: Many property managers in Carmel overlook this as a minor issue, but catching it early could prevent a full system failure.
2. 🔊 Unusual Noises

Are you hearing grinding, rattling, or screeching sounds from your AC unit? These could signal:
- Loose or disconnected parts
- A failing blower motor
- Debris caught in the system
🚨 Ignoring these noises can escalate the damage. Schedule an AC inspection immediately.

3. 💨 Weak or Uneven Airflow
If some rooms in your home are hotter than others, or if the airflow feels weak, it could be caused by:
- Clogged air filters
- Leaky or damaged ductwork
- A worn-out fan motor
🔍 Tip: Weak airflow strains your system and reduces efficiency. Fixing this early lowers energy costs.
Therefore, addressing this issue quickly is essential to avoid long-term problems. Get tips for improving your AC’s energy efficiency: U.S. Department of Energy – Air Conditioning Efficiency
4. 💧 Moisture or Leaks Around the Unit

Water pooling around your AC unit or ice on the refrigerant lines are signs of:
- Blocked condensate drain lines
- Refrigerant leaks (which can be hazardous)
🏠 Address leaks right away to avoid water damage, mold growth, or costly repairs.

5. 😷 Unpleasant Odors
If you notice a musty smell, mold might be growing in your ductwork. A burning smell, on the other hand, could indicate an electrical issue.
Both types of odors require immediate HVAC service to protect your health and safety.
