With the intense summer heat, it’s crucial for homeowners in Buford, Georgia, to keep their cooling systems running efficiently, but can AC units overheat? The answer is yes, and understanding the causes and solutions is essential to prevent discomfort and costly repairs. 

In this guide, Trammell Heating & Air will explain the main causes of air conditioner overheating, how to prevent it, and what to do if it happens. As a top provider of Buford’s reliable HVAC services, we can address your cooling system issues quickly and restore your home’s cool air when you need it most.

What Can Cause Your Air Conditioner To Overheat?

Air conditioners are designed to keep you comfortable during the hot months, but several issues can lead to overheating. 

External Environment

High outdoor temperatures can put extra strain on your AC, pushing it beyond its limits. During peak summer days, the ambient heat can cause your air conditioning unit to work harder than usual to maintain cool temperatures indoors. If not managed properly, this excessive operation can lead to faster wear and tear and potential overheating.

Refrigerant Levels

Low refrigerant levels make it hard for your air conditioner to produce enough cool air, causing it to overwork. Refrigerant is essential for absorbing heat from your home’s interior. If the levels are too low, the system must run longer to achieve the desired cooling, increasing the risk of overheating and potentially causing significant damage to the compressor.

Condenser Coil Function

Dirt and debris on the condenser coils can impair heat expulsion, leading to overheating. The condenser coils release heat from inside the home to the outside. When these coils are dirty, the heat transfer process is less efficient, causing the system to run hotter and longer, increasing the likelihood of overheating.

Electrical Components

Faulty wiring and malfunctioning components can disrupt normal operations and lead to overheating. Electrical issues pose a fire risk and prevent various air conditioner parts from functioning correctly. For instance, a malfunctioning fan could fail to cool the compressor, leading to overheating.

Air Filter Maintenance

Clogged air filters restrict airflow, forcing the AC to exert more effort and overheat. Regularly replacing or cleaning air filters is crucial to maintain proper airflow through your system. Restricted airflow causes the unit to strain, which can raise internal temperatures to dangerously high levels, potentially leading to an automatic shutdown or failure.

System Maintenance

Neglecting regular AC maintenance can leave unresolved issues in the system, causing overheating. Regular check-ups by a professional can catch and fix small problems before they escalate into major issues. These maintenance checks include inspecting and cleaning components like coils and filters, confirming the proper refrigerant levels, and ensuring the electrical system is up to par.

How To Prevent Your Air Conditioning System From Overheating

Can AC units overheat? Yes, but preventing your air conditioner from overheating is simpler than you might think. Here are some practical steps you can take:

  • Regular Maintenance: This includes cleaning or replacing air filters, checking refrigerant levels, and inspecting electrical components for any signs of wear or damage.
  • Clean the Condenser Coils: To improve efficiency, keep the condenser coils free from dirt and debris.
  • Proper Installation and Checks: Ensure your air conditioning system is correctly installed and that all components are functioning correctly.

What To Do When Your Cooling System Overheats

If you suspect that your air conditioner is overheating, act quickly to mitigate the damage and restore its functionality:

  • Turn off the unit.
  • Inspect and replace the air filters if they are dirty.
  • Clean the coils if you find any buildup of dirt or debris.
  • Contact HVAC professionals.
