If you have a home with an air conditioner, you likely want to make sure that it keeps running as well as possible in order to make sure that your home remains a comfortable temperature. You might not necessarily want to call a repair professional right away, however. Here is some troubleshooting you can do on your own before you call an air conditioning professional.
1. Check Your Circuit Breaker
If you find that your air conditioning unit will not go on at all, make sure that you check your circuit breaker. You don't want to call a professional and then have him or her come out and tell you that you just need to retrip the circuit. Simply check to make sure that you haven't actually tripped a circuit to ensure that you actually have power running to your air conditioning unit.
2. Change the Filter
If your air conditioner is no longer cooling down your house or room to the same degree that it used to, there is a good chance that the only problem is that the filter is full and needs to be changed. A clogged filter slows down airflow, reducing the amount of cool air that makes it to your home. All you need to do is swap out the dirty filter for a clean one and you will likely be good to go. If you have changed the filter and are still having issues, make sure that you call an air conditioning professional.
3. Get Rid of the Ice
If your air conditioner is no longer working at all and you can see ice formed on the unit, make sure that you melt the ice before calling a person that specializes in repairing air conditioners. Getting rid of the ice will make it easier for you to see if it is the cause of the problem and make it easier for a repair professional to actually work on it should you need his or her help. To get rid of the ice on your air conditioner, turn it off if it isn't off already. If you still have power to the fan, run just the fan. This will cycle hot air over the unit without generating more cold air and will help you melt the ice more quickly. Put a drip pan beneath your air conditioner if you have wooden floors to avoid ruining them if the melted ice will drip inside.
