You probably need your AC to function at its finest now, more than ever, since the summer sun is at its hottest and doesn’t seem like it’ll be backing down anytime soon. We depend on the air conditioner far too much and having anything bad happen to it right now will wreak havoc on our life. The irony of this situation is that most often our AC seems to run into problems at the peak hour of its necessity. Recognising the problem will help you seek the right kind of help. We’ve gathered some of the most common air conditioner problems and spoke to Mr Shyam Berde, Voltas’ Regional Service Manager, who gave us the following solutions to it.

Problem 1: AC does not blow cool air


Cause: Choked Filter

In order for an AC to blow cold air, it must have adequate air flow. The air circulates through the system and passes through the filter to give you cool and clean air. However, it the air filter is clogged or dirty from all the filtered dirt particles and debris over time, it restricts the air flow, thus causing little or no cool air to be circulated into the room.

Solution: Clean the filter or get the AC serviced

AC filters should be cleaned regularly. You can do it yourself by opening the air conditioner, pulling out the filter and cleaning it. Vacuum it first and then use some water and detergent to clean it. Remember to dry it thoroughly before putting it back. Replacing your filter every few years will ensure the air in your room isn’t compromised. Getting your AC serviced every few months will take care of this problem.

Problem 2: Indoor unit is leaking water inside the room


Cause: Drain pipe choked or drain slope disturbed

Ideally, the water that forms around the evaporator coil due to condensation, goes into a sloped drain and down the condensation drain line. However, any blockage or disturbance in the sloped drain will hinder the water from escaping through the drain and instead will go the only other way it can, that is back into your home.

Solution: Clean the drain outlet & check the slope

Several things like dirt, mould, insects etc. can cause a blockage. You can use a wet-dry vacuum or a hand pump to remove the blockage. However, getting an annual cleaning by a professional will help avoid this problem. Ask the service person to check the slope of the drain line too if the water still continues to leak inside.

Problem 3: The unit shuts on and off repeatedly


Causes: Sensor issue

Air conditioners feature a thermostat sensor that is located behind the control panel. This measures the temperature of the air coming into the evaporative coil and adjusts the condenser temperature accordingly. If the sensor is knocked out of position or is pushed inwards to touch the evaporative coil, the AC could cycle constantly by shutting on and off repeatedly.

Solution: Check the position of sensor

The sensor should be near the coil but not touch it. If it does, adjust the position by carefully bending the wire that holds it in place. Call a handyman to get this done if you aren’t too sure about it. Either way, it’s usually a sensor issue when the AC cycle acts erratically.

Problem 4: The outdoor unit’s making an unusually loud sound

Causes: Faulty outdoor unit fan

The fan in the outdoor unit of an air conditioner helps with the condensing process and to disperse the heat. The faint sound you hear from the outdoor unit is the fan doing its duty. However, when you hear a humming or rattling noise that’s unusually louder, it is linked to a faulty fan. There could be several reasons for it such as accumulation of dirt or the blades could be loose and could be touching the adjacent components.

Solution: Adjust the blades

Begin by cleaning the debris around the blade. Then check to see if the blades are loose and need a little tightening. Also, check to see if the blades are bent slightly as this is why is ends up touching the other components and creates that loud sound.

Problem 5: The room isn’t getting cold enough


Cause: Remote control setting disturbed

Something as simple as a disturbed setting in your remote can affect your AC experience. Sometimes the remote fails to send temperature change signals to the AC unit. Either way, it could only be a case of a faulty remote or its settings.

Solution: Check your remote and change your settings and modes

The display on the remote is only indicative but may not always be accurate. If you feel like the remote shows a certain temperature and mode but you feel otherwise, go back to the setting and redo them. If that doesn’t work, use the setting button directly on the AC. However, since all ACs don’t have a direct button, you may have to rely on the remote. Try changing the batteries or replacing the AC remote with a new one of the same brand.
