Common Problems That Cause The Need For AC Repair

Posted on: 29 March 2023

As the summer heat approaches, many people will rely on their air conditioning (AC) units to keep them cool and comfortable. However, just like any other mechanical system, AC units can break down, leaving you hot and uncomfortable. Here are four common causes of breakdowns that require AC repair.

Dirty Air Filters

The air filter in your AC unit is responsible for trapping dirt, dust, and other particles that can affect indoor air quality. Over time, the filter can become clogged with debris, which can lead to reduced airflow, increased energy consumption, and even system failure. If you have not been replacing the filters every three months or more frequently if you have pets, allergies, or live in a dusty environment, you will end up needing a technician for repairs.

Refrigerant Leaks

Refrigerant is a vital component of any air conditioning system, as it is responsible for cooling the air that is circulated throughout your home. If your AC unit is low on refrigerant or has a leak, it will not be able to function correctly, and you may experience warm air blowing from your vents. Refrigerant leaks can also cause your AC unit to work harder, leading to increased energy consumption and a shorter life span. If you suspect a refrigerant leak, it's essential to call a professional HVAC technician to diagnose and repair the issue.

Electrical Problems

AC units rely on electrical components to operate, including motors, capacitors, and relays. Over time, these components can wear out or fail, leading to system breakdowns. Electrical problems can also be caused by faulty wiring or circuit breakers. If your AC unit is not turning on or is experiencing intermittent operation, it's essential to have an HVAC technician inspect the electrical components and make any necessary repairs.

Poor Maintenance

Regular maintenance is crucial to the performance and longevity of your AC unit. Neglecting routine maintenance tasks, such as cleaning coils, checking refrigerant levels, and inspecting electrical components, can lead to system failure and expensive repairs. It's recommended to schedule annual maintenance with a professional HVAC technician to ensure your AC unit is operating correctly and catch any potential issues before they become significant problems.

AC breakdowns can be caused by various factors, including dirty air filters, refrigerant leaks, electrical problems, and poor maintenance. To avoid system failure and costly repairs, it's essential to perform routine maintenance tasks and address any issues promptly.
