Although you may not be a fully qualified air conditioning technician yourself, some problems about central air conditioning troubleshooting can be learned by reading on the internet or just listening to how your system is operating. Therefore, it is good to be acquainted with central air conditioners. It will be enough to have some basic knowledge about air conditioning in order to understand repair manuals or your service technician.
If you want to know about central air conditioning troubleshooting, be aware of the common problems with your air conditioning unit so that you might be able to fix them yourself.
1. Problems with the condensing unit may be due to the fact that there is no power or the thermostat setting is not set low enough to have the system come on. If the breaker is not tripped and the thermostat is set to come on, but the unit fails to cool, call your service technician
2. If cooling is not even throughout the room, obviously there is a problem with the duct work
3. If the unit does not cool sufficiently, this may be due to a dirty filter, a dirty evaporator or the blower wheel not operating.
4. If cool air is not produced, this may be because the blower motor has failed, or the blower wheel is not turning. It may also be caused by a dirty air filter restricting the air flow.
5. If the unit is turning on and off, this can be caused by dirty condensing coils which could lead to high head pressure on the compressor; or the system is low on Freon causing the compressor to short cycle.
6. If the system does not cool the rooms it should be cooling, this has certainly something to do with the duct work. In this regard, you will have to inspect the duct work for leaks.
7. If parts need replacing, call in a qualified service technician.
Dirt is the common finding of central air conditioning troubleshooting. Therefore you should have your system cleaned regularly. Do not wait until it breaks down before doing a preventative maintenance.
