Keeping your AC serviced on a regular basis will allow you to spend less on electricity and keep your room cool without any problems. As a precautionary measure, make sure your window AC is serviced once at the beginning of summer and once after it ends. On that note, here are the most common problems with window ACs.

1. An air conditioner's front is dripping with water

The problem lies in how the AC is mounted. Window ACs should be mounted with a slight slope towards the rear so that the condensed water flows out through the drain pipe. If the slope is towards the inside, water can drip from the front. It is therefore necessary to reinstall the air conditioner to resolve this issue.

2. There is too much cycling between ON and OFF of the compressor

Typically, this indicates a problem with the thermostat or the temperature sensor. First, make sure the temperature sensor is close to the evaporator coils. Next, make sure the AC filter isn't clogged. In the event that the problem persists, the thermostat may be at fault. To fix the problem, consult a professional.

3. Window AC ice formation

It is possible for the cooling coil to freeze if the level of refrigerant is much lower than the required amount. As a result, the moisture in the room condenses on the coil and freezes. An AC repair professional can help you resolve this issue of ice formation on your AC by accurately determining whether the refrigerant level in your AC is correct.

4. Problem with Window AC not working

It's most likely the AC unit's PCB that's damaged. There's no specific reason why the PCB failed. It can be due to surges in current, too frequent ON-OFF cycles, physical damage, etc. ICs or capacitors that have burned can simply be replaced and the repair is quite cheap. However, if the damage is greater, the entire PCB has to be replaced, which can be very expensive depending on the window AC technology used.

5. The cooling performance of a window air conditioner is low

A common cause of AC not cooling is a lack of coolant (Freon). The coolant circulates through the evaporator coils and cools the air flowing over it. When the coolant level falls below a certain level, the AC won't cool. The coolant leaks from the unit and the AC stops cooling. A professional AC repair technician will be able to accurately determine if the refrigerant levels are just right in the cooling coils. Clean your AC filters once a month to prevent clogged filters from lowering cooling performance.

6. Switching off the compressor too early without cooling it

As a result of an increase in temperature above normal, the temperature sensor cuts off power to the compressor. High temperatures can result from 2 reasons. One is an unstable power supply to the AC. The other is a lack of space outside for proper air flow. The AC should be at least 3 feet away from an obstruction at all times.
