It’s summer. It’s hot. The last thing you want when you walk into your house is to find out that your air conditioning unit is running but not cooling. There are a couple explanations for why your air conditioning unit is not cooling well, and here are some troubleshooting tips to get it back to normal working condition.
If the air conditioning unit is in fact running, but not cooling well enough, your filters may need to be replaced. If they are dirty and the pan underneath has no condensation water in it, then you need to replace the filter. In addition, you may want to check the coils inside and outside unit and clean them.
Your unit could be low on Freon, which could explain why the air coming from the system is not as cool as it should be. If you go to the outside unit and inspect the two copper pipes sticking out, the larger one should be cool to the touch, and the smaller should be warm/hot. Warm air should usually be coming out from the unit. If these situations are not the case, refrigerant may be necessary.
Another possible explanation is that some vents in your house are closed. Go around and make sure they are all open and not blocked by anything that may be preventing maximum airflow.
There could even be a problem with your thermostat, which means that it is not correctly reading and failing to relay the temperature you have set. If none of these solutions have helped, you should contact a professional for insight and help.
