Most Common AC Issues And How to Fix Them 

Having an air conditioning system in our homes or offices brings comfort and convenience, especially during hot and humid weather. However, just like any other appliance, AC units are prone to problems and malfunctions. The good news is that most of these issues are relatively easy to fix, with minimal effort and cost. In this blog post, we will dive into the most common AC issues faced by homeowners and how to resolve them.


Dirty or Clogged Filters

One of the most common reasons behind an AC not functioning efficiently is dirty filters. Dirty filters obstruct the airflow and force the AC to work harder, resulting in increased energy consumption and reduced cooling capacity. To fix this issue, regularly clean or replace the filters based on manufacturer recommendations. Some systems require a monthly filter change while others can go up to six months. Check your manual or contact a professional if you are unsure.


Low Refrigerant Levels


Refrigerant is what makes your AC cool the air. If your AC is not cooling as it should, the issue could be due to low refrigerant levels. This issue is typically caused by leaks in the system. Professionals like need to be called for such issues, give them the details of the problem, and they can test and refill the refrigerant accordingly.


Faulty Thermostat


If there is no actual problem in the AC system, yet your home isn't cooling down as it should, there may be something wrong with the thermostat. A faulty thermostat can cause incorrect temperature readings, resulting in an improperly functioning air conditioner. Try to clean the thermostat and make sure it is connected to the electrical wiring properly. If none of the basic tricks work, you might need to replace it.


Clogged Condenser or Evaporator Coils


The condenser and evaporator coils need to be clean to enable optimum cooling. Check the coils if you observe a reduction in airflow or feel warmer air than you should be. Dirt and debris can accumulate around these coils, causing them to clog up, reducing cooling efficiency. You may need to remove the unit's cover to check and clean the coils, or seek professional help and read reviews of Gustave A. Larson if you're uncomfortable doing so.


Damaged Compressor


A damaged compressor is a more severe issue and may ultimately need replacement. A damaged compressor may present as high electricity bills, poor cooling, or malfunction in the AC. If you suspect that you have a faulty compressor, call professionals immediately as compressors are generally complicated and dangerous to repair. 


Air conditioning units are essential for comfort and convenience. However, if you experience problems with the unit, don't panic. The most common AC issues usually have easy solutions. Check your air filters, clean the coils, ensure the thermostat is working correctly, test for refrigerant leaks, and observe the compressor's condition. If the issue is beyond your DIY skills, don't hesitate to contact professionals. By addressing these problems early, you can prevent more significant issues and ultimately avoid major costly repairs.
