One thing to remember is to give the air conditioner unit time to cool the home. If the air conditioner has just turned on, give it some time to work. If it has been unusually hot (or humid) the air conditioner may take longer than usual to cool the room.

5 DIY Ways to Fix an AC That Is Not Working
Before calling a qualified air conditioner repairman, there are a few simple steps you can take to troubleshoot your air conditioner problem.
1. AC Not Turning On
If your air conditioner won’t turn on, check the power.
- If it is a room air conditioner, make sure the plug is firmly plugged in
- Check the fuse or circuit breaker to ensure power is reaching the unit
- For a central air conditioner unit, try the reset button in the compressor’s control panel. Wait 5-10 minutes after the unit has stopped before resetting the compressor or resetting a circuit breaker.
2. Clogged AC Drain Line
When the weather is unusually humid, the unit may not be draining properly so you should check and make sure that the AC drain line is not clogged.
3. AC Not Maintained
When your central air conditioning system is not working properly there are a few things you can check before calling the repairman.
Make sure that the outside condenser is not blocked; is the grass too high, are there weeds or debris blocking it?
You may also need to clean your evaporator coil.

4. AC Not Cooling
If the unit is running but not cooling your home appropriately, make sure all windows and doors are closed and that the cold air is not leaking out of your home.
Other items to check are the air filters and coils. If these are not maintained properly, that can impact on performance.
5. Thermostat Problems
When your unit is running but not cooling the room to the desired temperature you may want to lower the thermostat by five degrees to see if it is a thermostat problem and not the air conditioner unit itself.
