Introduction
When your air conditioner refuses to turn on, frustration can set in quickly, especially in hot climates. However, before calling a technician, there are a few troubleshooting steps you can take to potentially fix the issue yourself. In this guide, we’ll walk you through five quick checks to diagnose common AC problems and determine if you need professional help.
5 Quick Checks Before Calling a Technician
Check the Thermostat Settings
Ensure your thermostat is set to “cool” mode and the temperature is set lower than the current room temperature. If the display is blank, replace the batteries and restart it.
Inspect the Circuit Breaker
A tripped circuit breaker could be the reason your AC isn’t turning on. Locate your home’s electrical panel and check if the breaker for the AC unit has tripped. If it has, reset it by flipping it back to the “on” position.
Examine the Power Supply
Make sure your AC unit is properly plugged in and receiving power. Sometimes, power cords get accidentally unplugged or damaged. Also, check if any safety switches on the unit have been triggered.
Check the Air Filter
A clogged air filter can cause your AC to overheat and shut down. Remove and inspect the air filter; if it’s dirty, replace it with a clean one. Regular filter changes can prevent future malfunctions.
Look for Frozen Coils
If your AC coils are frozen, it may prevent the system from running. Turn off the AC and allow the ice to melt before restarting it. Also, ensure airflow is not obstructed by checking vents and registers.
