Why is my AC Not Cooling My Home?
Why Is My AC Not Cooling My Home?
If your Split AC System, Heat Pump System or Package AC Unit isn’t cooling properly, several issues could be blocking cool airflow & keeping your AC from running at peak performance.
Read our brief guide that is designed to help homeowners solve their home AC issues.
1. Dirty or Clogged Air Filter
Your AC filter traps dust and debris, but if it gets clogged, it restricts airflow. Changing your AC regularly can help to prevent wear & tear, block airborne allergens & increase efficiency.
Signs that your air filter is dirty:
- Weak airflow
- Uneven cooling
- Warm air from vents
- Visible dirt & debris on filter
- Filter has not been replaced in the past 1-3 months
Solution: Check and replace the filter every 1-3 months, especially during summer.

2. Incorrect Thermostat Settings or Malfunction
A faulty thermostat can lead to cooling issues.
Signs:
- AC doesn’t turn on
- Cycles on and off frequently
- Blows warm air when set to cool
- Blows cool air when set to warm
- Incorrect or faulty display
Solution:
- Ensure it’s set to “Cool” mode and a lower temperature.
- Replace the batteries if needed.
- If issues persist, consider a thermostat replacement.
3. Low Refrigerant (Freon) Levels or a Leak
Your AC needs refrigerant to absorb heat. A leak reduces cooling efficiency.
Signs:
- Weak cooling
- Ice on the evaporator coil
- Hissing sounds from the indoor/outdoor unit
Solution: Contact Air Care for help from expert technicians who will locate and repair the leak.
4. Dirty or Blocked Outdoor Condenser Unit
The outdoor unit releases heat, but dirt and debris can block it.
Signs:
- AC struggles to cool
- Runs longer than usual
- Overheats
Solution:
- Contact Air Care to schedule HVAC Maintenance, including AC Coil Cleaning, Duct Cleaning & AC/Heating Maintenance Services.
- DIY: Turn off the AC and gently clean the condenser coils.
- Maintain 2-3 feet of clearance around the outdoor unit.

5. Frozen Evaporator Coil
The indoor evaporator coil absorbs heat, but if airflow is restricted, it can freeze.
Signs:
- Weak airflow
- Water dripping from the unit
- Ice on the indoor coil
Solution:
- Turn off the AC and let the ice thaw.
- Check for airflow restrictions like a dirty filter.
- If freezing happens often, call a technician.
6. Ductwork Leaks (For Ducted Split Systems)
Leaking ducts let cool air escape before reaching rooms.
Signs:
- Some rooms stay hot
- Higher energy bills
Solution: Schedule a professional duct inspection to seal leaks.
7. AC Unit Is Too Small or Aging
An undersized or old AC won’t cool efficiently.
Signs:
- AC runs continuously
- Never reaches set temperature
- Higher energy bills
Solution: Upgrade to a properly sized, energy-efficient unit.
