Air conditioners are an essential appliance. But, your AC might show up some problems sometimes. There is nothing to worry. Here, in this post I’m going to discuss about some of the most common air conditioner problems and their solutions.
Therefore, without further delay, please give it a reading and understand the problem and its cause.
It is very vital to know the reason behind the issue in order to solve them.
The AC Not Turning On
You might experience turning on the system. However, the system remains as it is. It could be due to a blown-fuse or a tripped circuit breaker.
To fix it, just rest the circuit breaker or replace the blown-out fuse.
Moreover, loose or broken wiring can also result in this issue. Also, it can be an issue with the thermostat.
Air Conditioner Not Cooling
This is one of the most common air conditioner problems. Here is how you can fix it and the cause behind the issue.
The Problem of Low Refrigerant
The air conditioner running on low refrigerant fluid fails to blow out cool air and therefore it cannot cool the room.
It is best to find out the leakage signs in order to fix it. These are the signs that indicate a low refrigerant level.
Once you get the leakage signs, contact a technician immediately.
However, note that in such a case, do not add more refrigerant fluid as it will again escape.
Some Strange Noises From AC
Often you experience strange noises from your AC. here are some of them with their reason behind it.
|Strange Noises||The Reason|
|A buzzing sound||Motor issues, loose parts, bad blower, refrigerant leakage, unclean AC coils|
|Screaming||Refrigerant leakage, pressure in the AC compressor|
|Clicking||Some issues in the thermostat|
|Clanking sound||Loose parts|
|Banging||Broken or some loose parts. Also, it indicates AC compressor replacements.|
|Rattling||Loose fan, clogging of duct, indicates deterioration.|
|Squealing||Issues with belts and motors( indoor & outdoor)|
If you experience any of these sounds, do call an electrician and go for a thorough check-up.
A thermostat detects the surrounding temperature and thereby sets the desired temperature accordingly.
However, if there is a thermostat malfunction, the HVAC system operates poorly.
Thus, you experience strange cooling.Therefore, check the following things to solve the issue.
Frozen Air Conditioner Coil
An air conditioner coil plays an important role when it comes to heat exchange. Thus, any issue in this section is a serious issue.
The reason behind this frozen AC coil is refrigerant leakage, broken fans, dirty air filters, clogged condensate lines, and thermostat issues.
However, to resolve the issue, first turn off the AC. It will actually save other units from severe damages.
Leave it for some hours so that the ice melts. You can even use a hairdryer to melt the ice faster.
Note that you must not cut the ice but melt it. Cutting it might end up damaging the AC coils.
However, if the issue persists, call a technician.
Air Conditioner Fan Not Working
If you are experiencing this issue, call for technician help. The reason behind this issue might be a broken circuit inside, or maybe the fan motor is burned.
Furthermore, it can also be an ice build-up in the AC coils.
This might be due to mold or mildew growth inside the system as the AC is not clean.
You can also experience foul odors if the electrical parts inside get overheated.
However, to solve this issue, you can clean the evaporator coil, condenser line and change the filter.
Also, stop running your AC for longer hours.
The AC Condenser Not Working
Here are the signs that indicate that the AC condenser is not working.
- There will be an uneven room temperature.
- The unit is ON; however, it does not cool the room.
- The condenser is shut down completely.
- Receive higher energy bills.
This malfunctioning of the AC condenser might be a result of the following.
- Wiring issues
- Unclean condenser and evaporator
- Thermostat issues
- Faulty motor and compressor
- Insufficient refrigerator
Finally, to fix this, you can repair it. However, if you find the repair is too costly, it is better to replace it with that money.
Water Leakage From AC
Often you find your system is leaking water outside when it is running. It can be due to the unit getting frozen, and later on, it leaks water.
However, you can find other reasons as well. For example,
To fix this water leakage, first, find out the reason behind it and then act accordingly.
The drainage problem is the most common problems in air conditioner. Most of the people have faced this problem at least once who have AC.
The moisture inside the air conditioner is removed through a drain line and then funneled into a drain.
However, if this drain is clogged, the tray overflows. As a result, the water backs up and overflows.
It also damages your system.
Therefore, to fix it, check whether the drain is clogged (due to dirt, lint, and other such) or not.
Thus, to sum up, these are some of the most common air conditioner problems that you face.
We have tried to guide you with possible fixes.
However, no matter whether you experience these problems or not, it is better to call a technician and go for a proper check-up once a year.
It will lighten your burden later on.
