How to fix an air conditioner that isn’t working right

Check the thermostat

When troubleshooting your air conditioner, the first thing you should do is turn it off and then back on. If the air conditioner is not making cool air, check the setting on the thermostat. Ducted air conditioners are especially hard to work with because they often have a lot of thermostats and zones.

 If you change the zones by hand, you might be in a warm room while the rest of your house is being cooled by your air conditioner. Use the app or the thermostat to cool down your room.

 Double-check doors

After setting your thermostat to work well, you should check your doors and windows. If the door to your room is open, your air conditioner might not work either, giving the impression that the room is not cold. We might not pay enough attention to the windows, leaving us to wonder where all the fresh air is going.

Older doors tend to be drafty, which lets warm air get in and move around more easily. When the air pressure in a house is too low, warm air can also escape through cracks and other small holes. Door snakes are easy ways to keep a room warm and move cold air around.

The compressor conundrum

Whether your air conditioner is split or ducted, the compressor is the system’s beating heart. It keeps the air pressure the same throughout the system, which makes thermodynamic transfer work well and gives us the cool air we all want. If the compressor in your air conditioner breaks, it will stop making as much cool air right away.

Thank goodness, there is no doubt about this. But even though your air conditioner seems to be running at full speed, you won’t get any relief from the heat. There could be problems with the compressor. As compressors get older, they tend to make more noise. Even though it may be annoying, it’s a good warning and reminder that your air conditioner needs to be serviced.


In some places, a blockage could be what’s wrong with the air conditioner. Most clogs are caused by the filter, which is easy to clean. If you don’t clean the filter often enough, it could get too full and let dirt and other things into the system. If the ductwork for a ducted air conditioner is too long or hard to get to, it could hide serious blockages. You can tell if your air conditioner is blocked and not cooling based on how it smells. If your air conditioner smells musty or moldy, it might be blocked.


Any air conditioners that are broken should be fixed or replaced. Even though air conditioners last a long time, it’s important to remember that all appliances have a limited lifespan. The performance ratios are just right. If your air conditioner isn’t cooling your home well, the problem could be how much it can do. It could also be taking a break.
