If your climate control isn't working, there are a few things that could be the culprit. First, check to see if the system is turned on. If it is, then the next step is to check the thermostat to see if it is set to the correct temperature. If the thermostat is set correctly and the system is still not working, the problem could be with the fan. Check to see if the fan is turned on and set to the proper speed. If the fan is on and working, the next step is to check the air filter. A clogged air filter can prevent the system from working properly. Finally, if none of these things are the problem, the issue could be with the compressor. If the compressor isn't working, the system won't be able to cool the air.
