Why Isn't My Air Conditioner Turning On?

Common Reasons Your AC Won’t Turn On

  • Thermostat Issues – Of all the potential issues that can arise with a home HVAC unit, thermostat problems are some of the quickest and easiest to solve.There are three main problems that can arise with your thermostat: it’s incorrectly set (e.g., if you accidentally have it set to “heat” instead of “cool”); has low or dead batteries; or is completely broken and irreparable, which quickly disables the whole system’s ability to function normally.

    Fortunately, all three of these issues can be taken care of right away, especially if all that needs to be done is simply flipping the switch to “cool” or replacing the batteries. If your thermostat is flat out broken, you’ll likely need to replace it; but this is still a far simpler and more affordable fix than a complete system replacement. Plus, if your broken thermostat wasn’t programmable, now is the perfect time to replace it with one. This way, you’ll not only restore your home’s cool, comfy atmosphere, but also start saving money on your monthly energy bill by programming it to regulate your home’s temperature while you’re asleep or away.

  • Breaker Issues – If your thermostat isn’t the culprit, the next area you should check is the circuit breaker. If something caused your breaker to trip, or go out, this prevents the electrical current that powers your system from ever reaching it. Before you try to reset it, search your home to see if you can identify what caused the trip so you can resolve the issue before resetting it. If you’re unable to identify the problem, go ahead and reset it, but resort to calling a local electrician to diagnose and solve the problem if it persists.

  • Dirty Filter – If it’s been a while since you’ve replaced your air filter, this could very well be the problem. Dirty or clogged filters not only contribute to poor indoor air quality, but can also cause your AC unit to “freeze up,” or stop turning on. Check your filter and replace it right away if it’s dirty.

  • Refrigerant Leak – Your home’s AC system, just as your vehicle’s, needs refrigerant to work properly. If the refrigerant levels are low or there’s a leak, the unit won’t function as intended. Contact a team of friendly, experienced AC repair specialists to have the issue resolved right away.

  • Damaged Motor – It should come as no surprise that if your AC unit’s motor is damaged or broken, it won’t turn on. Unless you’re a seasoned HVAC specialist, this is another issue that should be handled by a professional.
