Common Problems and How to Fix Them
1. Air Conditioner Won’t Turn On
Possible Causes:
- Tripped circuit breaker – Power surge or overload may have tripped the breaker.
- Thermostat issues – Incorrect settings or dead batteries.
- Loose wiring or faulty capacitor – Can prevent power from reaching the unit.
Troubleshooting Steps: ✅ Check the circuit breaker – Reset it if tripped. If it trips repeatedly, call an electrician.
✅ Test the thermostat – Ensure it’s set to “Cool” and the temperature is lower than room temperature. Replace the batteries if needed.
✅ Inspect wiring connections – If wires are damaged, contact an HVAC professional.

2. AC Is Running but Not Cooling
Possible Causes:
- Dirty air filter – Restricts airflow, reducing efficiency.
- Low refrigerant levels – May indicate a leak.
- Blocked condenser coils – Accumulated dirt can prevent proper heat dissipation.
Troubleshooting Steps: ✅ Replace or clean the air filter – Should be checked monthly.
✅ Inspect the refrigerant lines – Ice buildup can indicate low refrigerant. Call a professional for refilling.
✅ Clean the condenser coils – Use a coil cleaner and rinse with a garden hose.

3. Unit Short Cycling (Turning On and Off Frequently)
Possible Causes:
- Oversized AC unit – Cools too quickly, leading to rapid cycling.
- Dirty evaporator coils – Causes inefficient cooling.
- Clogged condensate drain line – Triggers a safety shutoff.
Troubleshooting Steps: ✅ Check the evaporator coils – Clean them if dirty.
✅ Unclog the condensate drain line – Use a vinegar and water solution to flush debris.
✅ Ensure proper unit sizing – If your AC is too powerful for your home, a professional might recommend adding a dehumidifier or replacing the system.

4. Water Leaking from the Indoor Unit
Possible Causes:
- Clogged condensate drain line – Water backs up and spills over.
- Frozen evaporator coils – Caused by low refrigerant or poor airflow.
- Improper installation – Drain pan may be misaligned.
Troubleshooting Steps: ✅ Flush the drain line – Pour a mixture of vinegar and warm water to clear clogs.
✅ Check for ice on evaporator coils – If frozen, turn off the AC and let it thaw before restarting.
✅ Inspect the drain pan – Ensure it's positioned correctly.

5. Unusual Noises Coming from the Unit
Possible Causes:
- Buzzing or humming – Electrical issues, loose connections, or failing capacitor.
- Rattling or banging – Loose parts or debris in the system.
- Hissing sound – Refrigerant leak.
Troubleshooting Steps: ✅ Tighten loose screws and panels – If rattling persists, check for detached fan blades.
✅ Check for electrical buzzing – If the capacitor is faulty, call an HVAC technician.
✅ Listen for hissing – If refrigerant is leaking, shut down the unit and call a licensed professional.

When to Call a Professional
While DIY troubleshooting can solve minor issues, some problems require a licensed HVAC technician.
Call a professional if:
✔️ Refrigerant levels are low – Only certified technicians can legally handle refrigerants.
✔️ Electrical problems occur – Faulty capacitors, wiring issues, or frequent breaker trips.
✔️ Compressor failure – The compressor is the heart of the system and costly to replace.
✔️ Persistent water leaks – Could indicate a deeper drainage issue.

Preventative Maintenance Tips
- Change the air filter every 1-3 months.
- Keep the condenser unit clear of debris and leaves.
- Schedule professional maintenance annually.
- Monitor energy bills – Sudden spikes can signal inefficiencies.
