Causes & Solution"},"content":{"rendered":"\n

In this intense heat, an AC can give us a touch of cool air. But due to various problems like weak airflow, blowing hot air, water coming out of the Air Conditioner<\/a> and unusual noises, we no longer get that premium experience from our AC. These types of problems become a headache for us.<\/p>\n\n\n\n

Air Conditioner Problem – Causes & Solutions<\/h2>\n\n\n\n

Some common AC problems and their solutions are discussed below:<\/p>\n\n\n\n

1. Weak Airflow<\/h2>\n\n\n\n

This problem occurs when an AC is running, but it cannot cool the room. It fails to blow strong cold air and delivers only weak airflow, which eventually causes problems and cannot cool the room properly. As a result, the AC cannot fully deliver the performance.<\/p>\n\n\n\n

Causes:<\/h3>\n\n\n\n

Clogged Air Filter:<\/strong> Sometimes dust and dirt block the air filter inside your AC. This causes airflow to pass through the filter fluently. <\/p>\n\n\n\n

Dirty Blower Fan:<\/strong> The internal blower fan of the AC collects dust over time. As a result, the blower fan cannot spin properly and it affects the airflow system.<\/p>\n\n\n\n

Solution:<\/h3>\n\n\n\n

Clean the Air Filter:<\/strong> This problem can be solved easily by cleaning the air filter. It restores the natural airflow and helps the AC perform perfectly. <\/p>\n\n\n\n

Clear the Space:<\/strong> It is important to maintain at least 1 to 2 feet of clear space around your AC unit to get proper air circulation.<\/p>\n\n\n\n

Professional Cleaning:<\/strong> Calling experts to solve this problem is the most reliable solution. They can easily remove extreme dirt from the internal blower fan and fix the AC immediately. <\/p>\n\n\n\n

2. Blowing Hot or Warm Air<\/h2>\n\n\n\n

When an AC delivers slightly warm air instead of cool air, it is a sign that the AC is having some issues. In this problem, it feels more like a normal ceiling fan\u2019s airflow than an air conditioner. <\/p>\n\n\n\n

Causes:<\/h3>\n\n\n\n

Wrong Remote Settings:<\/strong> The AC\u2019s remote settings might have been changed to fan mode instead of cool mode unintentionally. <\/p>\n\n\n\n

Dirty Outdoor Unit (Condenser Coils):<\/strong> Sometimes the AC\u2019s outdoor unit deals with excessive dust, mud or leaves. It cannot release the heat that produce from your home properly. For that, it delivers warm air instead of cool air.<\/p>\n\n\n\n

Low Refrigerant (Gas Leak):<\/strong> There’s a special type of copper pipe which realeses a gas to absorb heat from your house. If there is any leak in the copper pipe, the gas cannot absorb heat from your room and slowly leaks out. For that, the AC loses its ability to cool and makes the room feel warm. <\/p>\n\n\n\n

Bad Compressor or Capacitor:<\/strong> The compressor is the main part of the AC. It helps the AC to run smoothly. But if there\u2019s any problem with the compressor, the AC cannot function properly and delivers warm air.<\/p>\n\n\n\n

Solution:<\/h3>\n\n\n\n

Check the Remote:<\/strong> Sometimes, accidentally selecting the wrong option on the remote causes warm air to come out. That is why you need to check the remote, select ‘Cool Mode’, and keep the temperature between 22\u00b0C and 24\u00b0C.<\/p>\n\n\n\n

Clean the Outdoor Unit:<\/strong> Need to spray the outdoor unit thoroughly with water and clean the surrounding dirt. This will provide a good solution.<\/p>\n\n\n\n

Call a Professional:<\/strong> If the exterior fan is running but the air conditioner isn’t cooling down sufficiently, there can be a gas leak or a broken part. In these situations, hiring a technician to inspect the air conditioner, fix any leaks, replace the gas if needed, or change any broken parts is advised.<\/p>\n\n\n\n

3. Water Coming Out of the AC (Leaking Water)<\/h2>\n\n\n\n

Water drips from your AC’s indoor unit, damaging your room’s walls and furniture. It can damage other products nearby if it is not fixed on time.<\/p>\n\n\n\n

Causes:<\/h3>\n\n\n\n

Blocked Drain Pipe: <\/strong>When the air conditioner cools, it takes away the humidity in the air and turns it into water drops. A plastic drain pipe is used to remove this water. Water overflows into your chamber as this pipe becomes clogged with mold, algae, and dust over time.<\/p>\n\n\n\n

Frozen Evaporator Coils:<\/strong> The inside temperature of your AC falls below the freezing point and water turns into thick ice if your air filter remains unclean. When you turn off the AC, this ice melts quickly and overflows the drain tray.<\/p>\n\n\n\n

Solution:<\/h3>\n\n\n\n

Flush the Drain Pipe:<\/strong> Monitor the drain pipe properly. If there is any mud, dirt, or anything else stuck there, clean it up. Use a thin stick to complete the cleaning process perfectly. <\/p>\n\n\n\n

Melt the ice: <\/strong>If you see that there\u2019s ice stuck inside your AC, turn off the Cooling Mode in your AC and set it to Fan Mode. It will naturally melt the ice from the inside. Clean your filters right away so that it doesn’t happen again. <\/p>\n\n\n\n

Professional Pipe Clearing:<\/strong> A professional pipe cleaner can easily clean the pipe if the clog stays very deep. By using a pressurized pump, they can easily remove the clog from the pipe. <\/p>\n\n\n\n

4. Unusual Noises<\/h2>\n\n\n\n

In this situation, the AC makes loud sounds and strange noises like rattling, buzzing or grinding. This makes it very hard to sleep or sit comfortably in the room. <\/p>\n\n\n\n

Causes:<\/h3>\n\n\n\n

Loose Panels or Screws:<\/strong> A loose connection in the AC panel can cause such noises. Also, a screw that is not tight can cause this sound too. <\/p>\n\n\n\n

Blower Fan Imbalance:<\/strong> The blower fan inside the AC can make this noise when it spins. This happens if a piece of plastic breaks from the blower. The sound can also be created by dirt building up unevenly on the blower fan. <\/p>\n\n\n\n

Failing Motor or Compressor:<\/strong> A sharp or loud rubbing sound can also indicate that there’s a problem with the compressor. An old or worn-out compressor can cause this problem<\/p>\n\n\n\n

Solution:<\/h3>\n\n\n\n

Tighten Loose Parts:<\/strong> Press hard on the plastic cover of the indoor unit. If the noise stops, find the loose screw or clip and tighten it.<\/p>\n\n\n\n

Clear the Outdoor Unit:<\/strong> Turn off the power completely. Open the outer cover of the outdoor unit. Remove any leaves, sticks, or dirt stuck near the fan.<\/p>\n\n\n\n

Call a Professional:<\/strong> You need a mechanic if you hear loud, sharp, or rubbing noises. The technician will have to replace the damaged parts or repair the motor.<\/p>\n\n\n\n

5. Frequent Cycling (Turning On & Off Too Fast)<\/h2>\n\n\n\n

The air conditioner switches on, operates for two or three minutes, shuts off, and then comes back on a few minutes later. Turning the AC on and off uses too much electricity, but the room still does not get cold. <\/p>\n\n\n\n

Causes:<\/h3>\n\n\n\n

Bad Thermostat Sensor:<\/strong> The temperature of the room is detected by the thermostat. The sensor will mistakenly believe that the room is already extremely cold and turn off the compressor too soon if it is damaged or unclean.<\/p>\n\n\n\n

Overheating System:<\/strong> The outdoor unit overheats and shuts off automatically to prevent burning if it is exposed to direct, intense sunshine without any shade or if there is no ventilation.<\/p>\n\n\n\n

Solution:<\/h3>\n\n\n\n

Reposition the Sensor:<\/strong> A technician can easily clean or move the small copper sensor inside your indoor unit to solve this problem. <\/p>\n\n\n\n

Improve Outdoor Ventilation:<\/strong> Make sure the outdoor unit is not in a tight cage or covered up. This helps the hot air get out easily.<\/p>\n\n\n\n
