5 Signs Your Air Conditioner Isn’t Working and What to Do

Air conditioning keeps our homes comfortable during hot summer days. But if your air conditioner is not working, you may feel that heat more than anything else. A working AC unit can make or break your mood, especially during humid and hot summer days. If yours is not, it may be time to check on the AC unit and see if anything is broken. Here are 5 signs that your AC unit isn’t working and what to do about it. Note that this is not a comprehensive list of all AC unit problems. Instead, it’s a guide to help you determine the root cause of your broken AC unit and what to do to fix it.


Your AC Unit Is Running But Produces No Cooling

If your AC unit is running but produces no cooling, your thermostat may be out of whack. This can happen for a variety of reasons. Change the batteries if you think that may solve the issue, but if there is an issue with the wiring, you’ll need to call a professional.

Your AC Unit Is Making A Hissing, Whirring Or Vibrating Noise

If your AC unit is making a hissing, whirring or vibrating noise, that’s not normal! You will want to turn your AC off and call a professional as soon as possible if you hear these noises. Continuing to run the equipment may cause more damage.

You Think It’s Low on Freon

If you think the AC unit is low on freon, then it’s time to call our team. Freon is a gas used in AC units that pumps heat out of the house. Your AC unit becomes low on this gas when there’s a leak or a break in the closed system (it should not need recharged every year). To avoid more costly repairs, the leak needs to be fixed as soon as possible and the refrigerant levels need to be  corrected.

You See Dirt Or Debris Under Your Air Conditioner

If you see dirt or debris under your air conditioner, the AC unit likely needs a good cleaning. Whether it’s been a while since the last time you cleaned it or you had an issue with your AC earlier in the year, this is something that should be fixed right away. Too much dirt and debris on and around your AC can cause problems like corrosion of electronic parts and decreased efficiency.

Your AC Unit Takes A Long Time To Respond When You Turn It On Or Off

This is one of the first signs that your AC unit may be broken. When you turn the AC on, it takes a long time to respond and cool down the room. This can be frustrating when you’re in a hurry or feeling hot. Please note, if you are experiencing extreme summer temperatures, your AC will only be able to keep your home around 20 degrees cooler than the outside temperature. Be patient and understand its limits before calling a professional to evaluate your cooling system.
