What Gets Your Air Conditioner Broken?

As the mercury rises, your air conditioning (AC) system becomes your most trusted ally in maintaining comfort and sanity at home. 

However, AC units are complex machines, and when they stop working, it can turn a hot day into an uncomfortable and frustrating ordeal. Understanding the common reasons AC units break or stop working can help you prevent these issues or address them quickly when they occur.

Here are 8 common reasons why your AC might fail and what you can do to avoid or resolve these problems.

Refrigerant Leaks

Refrigerant is the substance responsible for cooling the air in your AC system. When refrigerant levels drop due to leaks, your AC’s cooling capacity decreases, eventually leading to system failure. Leaks can occur due to corrosion, damage to refrigerant lines, or poor installation.

Detecting and fixing refrigerant leaks requires professional expertise, as refrigerants are hazardous and require specialized equipment to handle them safely. If you notice your AC blowing warm air or see frost on the coils, it could indicate a refrigerant issue, and it’s best to call in a professional.

Forgetting About Maintenance 

One of the most common broken AC causes is a lack of regular maintenance, leading to clogged filters, dirty coils, and reduced system efficiency. To keep an air conditioner running smoothly, it’s necessary to clean and inspect it regularly. 

Filters, condenser coils, and other parts can become clogged with dust and debris, which reduces airflow and puts more strain on the system. This additional stress can cause components to wear out faster, leading to breakdowns.

Regular maintenance, including cleaning or replacing air filters and checking refrigerant levels, can help keep your AC running smoothly. Many HVAC companies offer maintenance packages, ensuring your unit receives the care it needs to stay in top shape.

Electrical Problems

AC systems have complex electrical components, including capacitors, contactors, and wiring. Electrical issues, such as faulty wiring or damaged capacitors, are common causes of AC breakdowns. These problems can lead to system malfunctions or even pose safety risks like electrical fires.

It’s good to know that signs of electrical issues include frequent tripping of circuit breakers, humming or buzzing noises, and inconsistent cooling performance. Given the risks associated with electrical repairs, it’s crucial to have a qualified HVAC technician address these issues.

Dirty Condenser Coils

The condenser coils in your AC system dissipate heat from the refrigerant, allowing the system to cool effectively. When these coils become dirty or covered in debris, they can’t release heat efficiently, causing the AC to work harder and potentially overheat.

Regularly cleaning the condenser coils can prevent this problem. If your AC unit is outdoors, keeping the area around it clear of leaves, dirt, and other debris is especially important. A clogged condenser can lead to reduced cooling efficiency and, eventually, system failure.

Faulty Thermostats

Sometimes the problem isn’t with the AC unit but the thermostat. A malfunctioning thermostat can lead to erratic cooling patterns, frequent cycling, or failure to maintain the desired temperature. This can cause your AC to work inefficiently or stop working altogether.

Upgrading to a smart thermostat can be a simple solution to this problem. These modern devices offer greater accuracy and allow you to control your AC system remotely, providing more consistent and efficient cooling.

Mechanical Wear and Tear

Over time, the mechanical components of an AC system can wear out, leading to breakdowns. Fans, compressors, and belts can all succumb to wear and tear, especially in regions with high temperatures or where the AC unit runs frequently.

Regular maintenance and timely replacement of worn-out components can help extend the lifespan of your AC system. If you notice unusual noises or vibrations, it’s a sign that a mechanical component might be failing, and you should have it inspected by a professional.

Improper Installation

An improperly installed AC unit can lead to problems, from inefficient cooling to system breakdowns. If the unit isn’t correctly aligned or electrical connections are faulty, it can cause premature wear and tear and reduce efficiency.

Professional installation is crucial to ensure your AC operates smoothly and efficiently. If you’re experiencing frequent breakdowns with a new AC unit, it might be due to installation issues, and a professional inspection is recommended. Find out more here. 

Age and End of Lifespan

Every AC system has a finite lifespan, typically around 10-15 years, depending on usage and maintenance. As the system ages, components become less efficient and more prone to failure. If your AC unit is nearing the end of its lifespan, breakdowns may become more frequent.

If you’re constantly repairing an old AC unit, it might be time to consider a replacement. Newer models are more energy-efficient and offer advanced features that can improve comfort and reduce energy costs.
