Top Reasons Behind What Causes a Sudden AC Failure

November 23rd, 2021

Island life is an absolute dream for those living in the continental United States. However, as most Hawaiians attest, this dream can quickly become a sweaty nightmare when your AC is not working. If your HVAC system experiences a sudden power failure, you may think the worst has occurred. You may even fear you will need to purchase a new system.

However, in reality, an AC tech can quickly resolve most power failures. So the next time that your AC suddenly stops working, consider the following possible causes behind the power failure and remember that the technicians at Island Comfort Air Conditioning are here to resolve your problems and restore functioning as soon as possible.

Frozen Coils

The coils within your AC are responsible for transporting the hot air outward but hinder the airflow if they become dirty from built-up debris. As a result, the coils can freeze, which can lead to a sudden power failure. To stop your coils from freezing over time, clean them regularly.

Damage in the Internal Components

Damage to the internal components of your HVAC system can lead to premature failure of your home’s AC. In particular, older models are more likely to experience this type of failure, but only due to a lack of maintenance. By replacing damaged compressors, fan blades, and electrical connections and contacts, you will be able to avoid any severe damage and shutdowns as well as prolong the life of your AC.

Broken Thermostat

If your AC fails to work because of a faulty thermostat, repairs are usually quick and effective. However, when your thermostat is damaged, your HVAC system will usually cycle on and off without stopping, which can lead to the system failing by overworking itself. 

The key is to catch the malfunction before any significant damages occur. You should immediately contact your maintenance team when you notice that your thermostat isn’t working correctly. Luckily, there are many thermostat replacement options today that offer an array of different features, such as room-by-room control options and WiFi connectivity.

Leaking Refrigerant

Anytime that the refrigerant levels within your HVAC system are low, there will be problems with functioning. Leakage can result from many reasons but is most often caused by an aging AC. When your AC has been running for over ten years, the components that hold the freon in the refrigerant can become damaged and result in leaks and system failure. This is typically a more severe issue, as the only practical solution is investing in a new HVAC system.

Lack of Annual Maintenance

Ultimately, it’s best to keep in mind that routine maintenance can help avoid all of these reasons behind AC failures. Schedule servicing for your HVAC system at least once a year to ensure that it is in working order. During servicing, your certified technician will be able to spot any potential damage or errors that could result in a system failure in the future. Furthermore, remember to leave all AC repairing to the professionals, as DIY attempts could result in additional problems.
