4 Steps to Diagnose Sudden AC Failures

Check for Airflow Problems 

When airflow is restricted, your system can struggle to cool your home or shut down altogether. Fortunately, many airflow issues can be solved with simple fixes. Start by examining your air filters. A clogged or dirty filter can choke your AC system, forcing it to work harder and reducing its efficiency. If your filter looks dirty, replace it immediately. Make it a habit to check and replace filters every 1–3 months, especially during heavy use. Next, inspect your vents. Ensure that none of them are blocked by furniture, rugs, or curtains. Restricted airflow at the vents can disrupt cooling throughout your home. Freeing up these obstructions can make a noticeable difference in your system’s performance. Don’t forget to check your outdoor condenser unit. Leaves, dirt, and grass can accumulate around the unit and block airflow. Clear the area around the condenser, and gently hose off the fins to remove built-up grime. Avoid using high-pressure settings because these can damage the delicate fins.

Keep Up with Maintenance 

Skipping routine care can lead to dirty coils, refrigerant leaks, and worn-out components, all of which can cause your system to break down unexpectedly. Scheduling annual maintenance with an HVAC company is important for your system’s longevity and efficiency. Ideally, you should book a tune-up before the start of the cooling season. During a professional maintenance visit, a technician will inspect your system, clean the internal components, and fix small issues before they become more expensive problems. In addition to professional servicing, there are maintenance tasks you can perform yourself. Regularly replace air filters, keep the area around your outdoor unit clear of debris, and monitor for unusual sounds or performance issues. A little proactive care can go a long way in preventing unexpected breakdowns.
