Is your air conditioner not turning on? It can be frustrating, especially during hot weather. But before you panic, there are a few simple troubleshooting steps you can take. Whether your AC won’t turn on after a power outage, or your thermostat is on but AC not working, we’ve got you covered.
At AirChill AC Maintenance and Duct Cleaning, we specialize in keeping your cooling system running smoothly. Here’s how to troubleshoot and fix common AC problems.
1. Check Your Thermostat Settings
One of the most common reasons an air conditioner won’t start is incorrect thermostat settings. Ensure that:
✔ The thermostat is set to “Cool” mode.
✔ The temperature is set lower than the current room temperature.
✔ The batteries are not dead.
If your air conditioner is not responding to the thermostat, try replacing the batteries or resetting the thermostat.
2. Check the Circuit Breaker
If your AC unit won’t turn on but the breaker is not tripped, check the disconnect switch near your outdoor unit. It may have been turned off accidentally.
However, if the breaker is tripped, reset it and see if the AC starts. If it trips again, there could be an electrical issue that requires professional repair.
3. Inspect the Air Filters
A clogged air filter can restrict airflow, causing your central air conditioner not to turn on. Dirty filters can also make your AC work harder, leading to overheating.
👉 Solution: Replace or clean your air filters every 1-2 months for better performance.
4. Check the Outdoor Unit for Damage
If your AC is not working after a power outage, the capacitor or compressor might have been damaged. You may also need to reset your air conditioner after a power surge.
How to Reset Your Air Conditioner That Won’t Turn On:
1️⃣ Turn off your AC unit at the thermostat.
2️⃣ Switch off the power at the circuit breaker.
3️⃣ Wait for 5 minutes.
4️⃣ Turn everything back on and check if the AC starts.
5. Check If the AC Fan Is Running but Not Cooling
If your air conditioner is not turning on but the fan is running, it could mean:
- The compressor is faulty.
- The refrigerant levels are low.
- The ducts are dirty or blocked.
Regular duct cleaning by AirChill AC Maintenance can improve airflow and efficiency, ensuring your home stays cool.
6. What If Your AC Won’t Turn On After Changing the Thermostat?
If you’ve installed a new thermostat and your AC won’t turn on, check the wiring. Incorrect wiring can cause communication issues between the thermostat and the AC unit.
✔ Solution: Ensure all connections are secure, or call a professional for help.
