5 Signs That Your Air Conditioner Needs Maintenance 1

Weak Airflow

If your air conditioner is blowing weak or little airflow, it’s a clear sign that your unit needs maintenance. When air filters and coils become dirty, it restricts airflow, which reduces the air conditioner’s ability to cool a room effectively. A proper cleaning of the air filters and coils is often enough to resolve this issue.

Odd Noises

If you hear odd noises coming from your AC, it’s a clear indication that there is something wrong with your unit. These noises could range from grinding, squealing, to rattling noises. Grinding noises usually indicate that a metal component of the air conditioner is rubbing against another part, while squealing often means that there is a problem with the fan. Rattling noises indicate that the air conditioner’s internal parts have become loose and need an expert’s immediate attention.

Weird Smells

If your air conditioner is giving off a weird smell, you should immediately get your air conditioner serviced. This could be a sign of mold, mildew, or even a burning smell. A musty smell, for example, indicates that there is moisture or humidity in the air conditioner, which can cause mold and mildew to grow inside the unit. A burning smell can be due to the inner workings of the AC unit overheating, which can cause an electrical fire.

Frequent On/Off Cycles

If your air conditioner is frequently turning on and off, known as short-cycling, it’s a sign of a major problem. This occurs when the air conditioner is not able to complete a full cooling cycle. The most common cause of short-cycling is a dirty air filter. Other factors, such as a malfunctioning thermostat or a faulty compressor, can also cause the unit to short cycle and require professional attention.

Increased Energy Bills

Lastly, if you notice a sudden spike in your energy bills, it could be a clear sign that your air conditioner is in need of maintenance. When your air conditioner works harder than usual to keep the temperature comfortable, it requires more power and energy to function, which can lead to higher bills. A proper cleaning, replacing any worn-out parts, and ensuring that your air conditioner is running efficiently can help reduce your energy costs.


Preventive maintenance is key to maintaining the efficiency and longevity of your air conditioners. Regularly cleaning and checking your unit can help identify any problems early on and save you money in costly repairs. In addition to these tips, be sure to have your air conditioner professionally serviced at least once a year. By doing so, you can ensure that your unit will run smoothly and keep you cool for many summers to come.
