Air conditioners (AC) are essential home appliances when the summer season starts to pave the way. However, after their service for the past summertime, most homeowners tend to forget to maintain their air conditioners. Like most appliances, AC needs a regular tune-up from time to time. Doing this will keep you updated on maintenance issues that you need to address. Catching any potential problems beforehand will save you money for costly repairs and help keep your AC in optimum condition. 

To guide you, here are some common AC problems that you might encounter and how you can quickly fix them before the weather gets too warm:


Indoor Water Leaks


One of the most frequent air conditioner issues is a water leak, which may be repaired by a professional or with a do-it-yourself remedy at home. If you notice water leaking from the interior unit of your air conditioner, it is then due for maintenance. Water leaks from air conditioners may occur when the system’s condensate drain becomes blocked due to algae or fungus, allowing water to back up the pipe and into your house. Another possibility is that your condensate pump has failed and has to be replaced.

Fix a leak by using a wet or dry vacuum to clear a blocked condensate line. Pour 6 ounces of vinegar down the drainpipe to eliminate fungus and algae growth. The precise position of the drainpipe inside your device may be hard to locate, so check the user handbook first.


AC Refrigerant Leak


AC refrigerant, commonly known as Freon, is in charge of chilling the air in your air conditioning unit. As the name implies, it is the actual mechanism by which an air conditioner cools your house. However, the refrigerant may leak at times, reducing the effectiveness of your air conditioner. Furthermore, leaks may be hazardous to your surroundings.

In the event of a small leak, you may need to do nothing more than fill up the refrigerant. In the case of a significant problem inside the pipes, however, the whole network may need to be replaced. When refilling the refrigerant, take care, not to overload or undercharge it. If the refrigerant load meets the manufacturer’s requirements, the efficiency of your air conditioner will stay exceptional. If necessary, contact a professional as soon as possible to get the leak repaired to prevent future AC troubles.


Dirty Filter


An air conditioner filter is necessary for maintaining the airflow clean and free of dust and contaminants. A blocked air filter limits airflow, lowering the effectiveness of your air conditioner. A filthy filter also decreases the system’s capacity to chill the air properly. Always follow the filter manufacturer’s recommendations for changing or cleaning the air filter. Smart AC controllers can assist you in monitoring the condition of your system’s filters. They may send a notification when it’s time to change or clean the air filter.


Frozen Evaporator Coil


Your air conditioner may cease efficiency due to a frozen evaporator coil. If your air conditioner does not get enough air to function, the evaporator coil freezes. A frozen evaporator coil may cause your air conditioner to freeze and perhaps cease operating. Sheets of ice may build up on the coil at times. When this happens, it prevents the refrigerant in the coil from absorbing latent heat. This AC issue can interfere with the air conditioner’s smooth operation, so you need to address it quickly. 

Defrost the evaporator coil to address this concern. You may accomplish this by not using the unit for about 24 hours. It takes the same amount of time to defrost the frozen coil thoroughly. Using a hairdryer will expedite the process. However, take care not to overheat the coil. In the event of moderate frost, keep your system on fan mode since the blower fan melts the ice without shutting down the unit. You will also likely need to contact an expert to resolve the issue.


Failing AC Fan


The air conditioner’s exterior unit distributes heat from inside to outside through a fan positioned in the external unit. If the fan placed outside the home does not function properly, appropriate heat transmission will not occur. As an outcome, the compressor in the air conditioner may overheat or trip the safety load. The worst-case scenario is that it causes internal compressor damage, necessitating installing a new AC to beat the summer heat.

If your AC fan stops working, there may be a problem with your system’s wiring or a loose part somewhere. Remove the outer shell and physically examine the situation. However, be sure to switch off the power before you begin.

Final Thoughts

AC-related problems are a common worry that owners have before or during peak air conditioner operation. You must promptly address these issues to avoid more significant air conditioner troubles. Always check your air conditioner, thoroughly analyze common problems, and resolve them as soon as possible. Regular air conditioner maintenance may also help you identify underlying problems that might impair the operation of your unit or even lead to AC malfunction.
