Summer is in full swing, and your air conditioner is working overtime to keep your home cool. However, mid-summer AC issues can disrupt your comfort and lead to frustration. At J. Halligan & Sons, we're here to help you troubleshoot common AC problems so you can stay cool and comfortable all season long. Let's explore some typical issues and how to address them.
1. Insufficient Cooling
Problem: Your AC is running, but your home isn't getting cool enough.
Solution:
- Check the Thermostat: Ensure it's set to "cool" and the temperature is lower than the current room temperature.
- Clean or Replace the Air Filter: A dirty filter can restrict airflow, making it harder for your AC to cool your home.
- Inspect the Condenser Unit: Make sure it's free of debris and the condenser coils are clean.
2. AC Unit Won't Turn On
Problem: Your air conditioner isn't turning on at all.
Solution:
- Check the Power Supply: Ensure your AC unit is plugged in and the circuit breaker hasn't tripped.
- Examine the Thermostat: Replace the batteries if needed or check for any wiring issues.
- Consult a Professional: If these steps don’t work, there could be a more serious issue that requires expert attention from J. Halligan & Sons.
3. Strange Noises
Problem: Your AC unit is making unusual noises such as grinding, squealing, or banging.
Solution:

- Fan Issues: Check the fan for any obstructions or damage.
- Motor Problems: If you suspect an issue with the motor, it's best to call J. Halligan & Sons for a professional inspection.
4. Water Leaks
Problem: You've noticed water pooling around your AC unit.
Solution:
- Clogged Drain Line: Clear any blockages in the condensate drain line.
- Frozen Evaporator Coils: Turn off the AC and let the coils thaw. Clean or replace the air filter to prevent future freezing.
