When summer hits Mississauga, a fully functioning air conditioner isn’t just a luxury—it’s a necessity. But what happens when your AC not working or AC not cooling properly? It can be frustrating, uncomfortable, and sometimes even a health concern during extreme heat. At 365 Comfort, we understand how crucial it is to restore comfort fast.
In this blog, we’ll walk you through common reasons your AC might not working or cooling and how you can troubleshoot (or when to call a professional).
Why Is My AC Not Working or Cooling?
If your AC not working and AC not cooling, it could be due to several common issues or reasons:
1. Thermostat Issues
Sometimes, the issue isn’t the AC unit at all—it’s the thermostat. If your thermostat isn’t working properly or is set incorrectly, your system won’t turn on or won’t cool as expected.
2. Dirty or Clogged Air Filter
A dirty air filter restricts airflow, making it harder for your system to cool the air effectively. This is one of the simplest causes of an AC not cooling and is often overlooked.
3. Low Refrigerant Levels
Refrigerant is what cools the air inside your home. If the levels are low due to a leak or insufficient charge, your AC won’t be able to cool properly. You may also notice ice on the refrigerant line or a hissing sound.
4. Electrical Issues or Tripped Breakers
An electrical issue could prevent your AC from running at all. Check your circuit board or breaker to make sure nothing has tripped. Still no power? It might be time to call 365 Comfort for an expert inspection.
5. Dirty Condenser Coils
Your outdoor unit (condenser) can become clogged with dirt, debris, or leaves, especially during spring and early summer. This prevents proper heat transfer and could cause the AC to stop cooling efficiently.
Quick DIY Fixes Before Calling the Pros
Before scheduling a repair, try these quick checks:
- Make sure the thermostat is set to “cool” and the temperature is lower than room temp.
- Check and replace the air filter if it’s dirty.
- Clear debris from around the outdoor unit.
- Check the breaker box for any tripped breakers.
If none of this work, and your AC not working and AC not cooling, it’s time to bring in a certified HVAC technician.
