When rooms are blocked off and air movement throughout the house is interrupted, common central air conditioning problems develop. If you have a room air conditioner, though, the reverse is true. And there's a problem with the operation. Close your home's windows and exterior doors as much as possible to isolate the room or a set of related rooms from the rest of your house. While keeping that in mind, let’s take a look at some of the most common issues that you will come across in your air conditioning unit.

Water leaks

If you see water leaking from your air conditioners inside unit, it's time for a tune-up! Water leaks from an air conditioner may occur when the system's condensate drain becomes blocked with algae or fungus, causing the water to back up the pipe and into your home. Another possibility for this AC problem is that your condensate pump has totally failed and has to be replaced.

One of the most common air conditioner problems is a water leak, which may be remedied with the aid of a specialist or a home DIY remedy. A wet or dry vacuum can be used to clear a blocked condensate line. To destroy fungus or algae build-up, throw 6 ounces of vinegar down the drain line. If you're unsure where the drain pipe is located in your device, review the user handbook first.

Water leaks from the outdoor unit

On hot summer days, a pool of water may form outside the home, directly beneath the compressor of your air conditioner. This might be due to a number of factors, including a clogged air filter, a damaged condensate pan, a faulty AC seal, or incorrect installation.

After you've figured out what's wrong with your air conditioner, the first thing you should do is switch it off and unplug the power supply. If this problem is not addressed quickly, things might get complicated. You may need to contact a professional for such an air conditioner issue.

Refrigerant leaks

Freon is another name for AC refrigerant, which is responsible for chilling the air in your air conditioning system. It is, as the name implies, the actual mechanism by which an air conditioner cools your home. A refrigerant leak (link to article) is a typical AC unit problem that can impair the efficiency of your air conditioner. Furthermore, leaks might endanger the immediate surroundings.

In the event of a tiny leak, you'll need to top up the refrigerant and make a quick repair. If a bigger defect occurs inside the pipes, the entire network may need to be replaced. Be cautious not to overcharge or undercharge the refrigerant when recharging it. If the refrigerant charge follows the manufacturer's requirements, the performance of your air conditioner will stay excellent.

You can detect a leak at home using a variety of methods. Analyze the air conditioner problem once it's been discovered, then take the required steps to fix the leak. To avoid additional AC difficulties, contact a professional as soon as possible and get the leak repaired.

Unclean filters

The function of an air conditioner filter is to keep the airflow clean and free of dust and contaminants. The airflow is restricted by a clogged air filter, which reduces the effectiveness of your air conditioning system. A filthy filter also decreases the system's capacity to efficiently chill the air.

If your air conditioner's airflow seems stuffy or blocked, check the air filter, and clean it, since it's most likely the filthy air filter that's preventing airflow. Pet owners should be particularly cautious when it comes to air filters since they will need to replace them more frequently as a result of pet fur.

During peak seasons, when the air conditioner is used the most, you should clean your filter every two weeks and replace it every two months. Smart AC controllers can also keep track on the status of your system's filters. They might transmit an alarm when the air filter needs to be cleaned.

Damaged compressor

The compressor, which assists refrigerants in heat exchange and maintains AC pressure, is one of the most important AC components. AC compressor failure can be caused by dirty coils, fluctuations in refrigerant levels, and a lack of maintenance.

The compressor will grow overheated and cease operating if there isn't enough refrigerant. If there is more than what is necessary, the extra refrigerant will cause the unit to overheat, causing it to fail. It's most likely a compressor issue if your air conditioner isn't cooling correctly or detects a weak HVAC airflow. To resolve this typical AC issue, contact your local air conditioning service. If the compressor is severely damaged, it is preferable to replace it rather than conduct air conditioning repair.

Frozen evaporator coil

Due to a frozen evaporation coil, the air conditioner stopped operating. A frozen evaporator coil might be the cause of your air conditioner's inability to cool effectively. It is a frequent problem with household air conditioners that arises when junk build-up prevents your unit from receiving enough air to work correctly.

The dirt on the coils inhibits airflow, preventing warm air from reaching the refrigerant. The refrigerant gets excessively cold in this situation, and any moisture on the coils freezes. The coil becomes covered in ice over time, preventing the refrigerant from collecting latent heat. This AC issue causes your home's air conditioning to malfunction.

Failure in capacitor

When your air conditioner switches on and off abruptly, followed by a clicking sound, it might be a symptom of a capacitor problem. A capacitor is a crucial component of your air conditioner that provides the motor with the first push it needs to start functioning. When your air conditioner needs to work hard in the summer heat, the capacitor might overheat. Power fluctuations, as well as frequent changes in the thermostat setting, might harm your capacitor.

Make an appointment with a specialist to get your capacitor inspected. Unfortunately, due to the risk of electric shock, you cannot fix or replace it on your own.
