Air conditioner not turning on?

What to Do if the Air Conditioner Won’t Turn On

I am not the best person in emergency or high-stress situations. For example, when the fire alarm went off while I was cooking, my first reaction was to simply cover my ears and stand there with a shocked look on my face. Not my proudest moment.


Though some people may not consider an air conditioner not turning on a true emergency, I think we all know that when the weather is hot even the littlest things can become very stressful. In order for you to react a little better than me in this type of setting, here are some tips for what to do if your air conditioner does not turn on.


First of all, check your thermostat. Is it set to below the current room temperature or to cool? If not, set your thermostat at a cooler temperature.


If that does not work, check the electrical panel. Just like when you have lights that will not turn on or an outlet that does not work, the air conditioner’s fuse could be blown or the breaker could be switched to off. If so, make sure they are all the way off and then flip the breaker back to “on.”


Also, sometimes there is a disconnect box with outdoor fuses for the air conditioner right by the unit. Make sure to also check those-you may have to get new fuses. However, it is probably a good idea to turn those fuses off before checking them.


Last but not least, check your filters. Often, your furnace and air conditioner share the same duct work and therefore the same filter. So even though it is sweltering hot, your furnace still plays an intricate part in keeping your home cool. Make sure the one or both filters are clean. A dirty filter restricts airflow and causes your unit to not work well or not at all.


If none of this advice helps, you may proceed to putting your hands over your ears. Or, you could do the more productive thing and call a certified, professional contract or like A.B. May to help. Questions? Contact A.B. May!
