Common Air Conditioner Troubleshooting

Save money by doing your own air conditioner troubleshooting to address common cooling issues.


Once the intense summer heat hits town, it is crucial to have a fully-functional cooling system in place just to survive. But because of the increase in workload, your unit may break down or stop working all of a sudden. That’s when you have to be ingenious and do your own air conditioner troubleshooting to address cooling problems you often face during summer. Not all the time you need a professional to do some easy fixes on your system. Try some of these air conditioner troubleshooting yourself:


Air condenser is not running.
When faced with this problem, inspect the power to ensure you have plugged your unit to an electrical source. If it is connected, examine for a tripped circuit or a blown fuse. Turn the power back on and wait if it starts.


Another likely reason is not setting up the thermostat correctly. Reduce the thermostat’s temperature about five degrees lower and check if it kicks on. If it doesn’t, blame a faulty compressor or motor as the cause. If that’s the case, it’s beyond your limited knowledge and skills so better contact an expert as soon as you can.


Insufficient air cooling.
If you notice your AC can’t condition your home sufficiently, try lowering your thermostat about five degrees lower. If the problem persists, the cause may be a filthy evaporator. Clean your evaporator carefully and allow it to run for several hours. If that does not solve the problem, your air conditioner may be smaller than what your living space requires.


Remember that the extreme temperature outside can affect the effectiveness of your cooling unit. If the outside temperature is at 100 degrees or higher, it will be hard for your AC to maintain a 62 degrees temperature within your home regardless of the amount of cold air it blows especially if your home has plenty of windows that let in plenty of sunlight. Always check with an expert before deciding whether to change your cooling unit especially if the summer heat is putting too much strain on your AC.


Air conditioner runs but does not cool.
If your home still stays warm even if your AC is running, inspect your thermostat. Then, check your condenser whether it is clogged or filthy? Clean and take off the blockage if there’s any. Tall grass, weeds, and other similar airborne particles can clog your unit’s condenser.


If your AC still does not deliver cold air, it may be due to an insufficient refrigerant level or a faulty compressor. Remember that only a professional cooling technician can address issues like these.


Air conditioner cycles on and off constantly.
Again, it is often due to a clogged or filthy condenser unit. Just clean your unit and get rid of obstructions to fix the problem.


When do you need to contact an HVAC expert for help?
You can clean your unit without requiring the assistance of a professional as long as you are familiar with the basic parts of your unit. But for issues involving the refrigerant, only an HVAC professional can work on that. After doing some simple air conditioner troubleshooting but the problem persists, contact an expert right away.
