The smell might be because of something burning, including the wires or a dirty filter, which needs replacement. The damage might also be caused by mold growing within your AC.

Bizarre Sounds

Most of the modern ACs are designed to work without noise. You won’t even hear the motors rotating, unless when starting or when going off. When you start hearing louder sounds from your AC, then it shows something is wrong. Any screeching, banging, or grinding might mean there is something broken, including the movable parts. It can also be caused by debris inside the equipment or loose belts. When you hear such sounds, you have to put the equipment off to avoid further damage and call the technician.

Poor Airflow

The amount of cold air you will receive from your AC depends on the adjustments. Lower settings mean you require little cooling while putting it full shows you need maximum cooling in your house. It reaches a point where your AC has poor airflow, regardless of the setting. This means it’s struggling to work, and something is blocking the air. You will need a technician to determine the cause and repair your AC, including changing the air filters and cleaning the ducts. Poor airflow can also result from the faulty fan, weak motor, and debris on the vents.

Leaking AC

Your AC has a designated outlet that removes the condensed water. It directs this water to the outside outlet, which drips constantly depending on the usage. Your equipment should be dry at all times. When you see water dripping from strange places, including on the air outlet, it shows a condensation problem, and it needs an immediate checkup. Immediate help will prevent growing molds and mildew, which causes further damage to the equipment. 

The above are some common reasons which will make you call a technician to have your AC checked and serviced. Even without the above signs, you should have scheduled maintenance at least once a year, depending on your location. Regular servicing prevents the above issues and also increases the lifespan of your air conditioner.
