04 Aug Air Conditioning Unit Won’t Turn On? Troubleshooting Tips
Even in Ann Arbor and surrounding areas of SE Michigan summer brings hot weather. When your air conditioner does not turn on, you may be left wondering what the problem is – and if it is going to require a new system or repair, either of which can be costly. There are a few minor issues that can cause your A/C not to turn on, and a total breakdown that happens without warning is rare, thankfully. Consider the following when troubleshooting your cooling system.
Air filter clogged. While it is a simple thing, a dirty or clogged air filter may prevent the A/C from coming on, as the filter allows good airflow and even helps prevent possible damage to the components of your system. Replace the filter then try turning the air conditioner on.
Thermostat set too high or on the wrong setting. If you desire a temperature of 76 degrees and the thermostat is set on 80, it will not come on. It is also important to make sure the thermostat is switched to the “cool” setting. Lower the temperature or set to “cool” and your system should come on.
A circuit breaker that’s tripped. Circuit breakers trip occasionally and are usually related to a power surge. Locate the breaker for your A/C in the main circuit box and reset it; this will likely fix the problem. However, if this happens frequently, you will want to have an electrician take a look to determine what the problem may be.
Thermostat issues. Thermostats do not last forever, particularly programmable thermostats that rely on batteries. It could simply be a matter of putting new batteries in if the screen is blank, or replacing the thermostat if new batteries do not do the trick.
Leaking refrigerant. Refrigerant is a liquid air conditioners must have in order to provide cool air. It isn’t unusual for A/C systems to experience leaks, something a skilled HVAC professional can diagnose and take care of if this is the problem. Refrigerant loss can result in inadequate cooling or your A/C not turning on.
