what to do when your ac stops working

When your AC stops working, the discomfort can quickly become unbearable, especially during the sweltering summer months in Katy, TX. A malfunctioning air conditioner can turn your home into an oven, making it difficult to find relief from the heat.

In addition to the inconvenience, this situation poses serious health risks, particularly for the elderly, young children, and those with pre-existing health conditions. It can also leave you wondering what to do if your AC stops working and when to call for AC repair. 

Understanding the basics of your AC system and how to reset your unit for troubleshooting purposes can save you time, money, and a lot of sweat. In this guide, 4C A/C & Heating, LLC, a leading HVAC technician in Katy, TX, will explain what to do when your AC stops working. 

Things To Check When Your Air Conditioner Stops Working in Katy, TX

When your air conditioner stops working, you might be able to identify and resolve the problem without needing professional assistance. Here are some common system components you can assess for signs of trouble and how to fix them:

Thermostat

The thermostat is often the first place to check if your AC isn’t working. It may be that the settings were accidentally changed, causing the system to stop cooling your home. Start by ensuring your thermostat is set to “COOL” rather than “HEAT.” This simple switch might be the root of the problem.

Additionally, confirm that the thermostat is set to “AUTO” instead of “ON” to prevent the fan from running constantly without cooling the air. This setting ensures the fan only runs when the AC is actively cooling. If your thermostat has a battery, see whether it needs to be replaced. A weak or dead battery can cause the thermostat to malfunction, leading to cooling issues.

Air Filter

A dirty air filter can significantly affect your AC’s performance by restricting airflow and making it harder for your system to cool your home. A clogged filter forces your AC to work harder, leading to overheating and system failure. Inspect the air filter and replace it if it appears dirty or clogged.

Filters should typically be replaced every one to three months, depending on usage and air quality. Regularly changing the air filter can prevent many common issues, such as poor airflow and increased energy consumption, and keep your system running efficiently.

Circuit Breaker

Sometimes, the problem may not be with your AC unit but rather the electrical system. Power surges or other electrical issues can trip your circuit breaker, cutting power to your AC.

Check your home’s electrical panel for a tripped breaker and reset it if necessary. If your breaker frequently trips, it might indicate a more significant electrical issue that needs professional attention. Additionally, ensure the outdoor breaker fuse is positioned correctly. This fuse is often located near the outdoor unit and can be another point of failure.

Air Duct Connections

Leaky or disconnected air ducts can lead to inefficient cooling and other issues. Over time, ductwork may develop gaps or become disconnected, allowing cooled air to escape before it reaches your living spaces. Inspect accessible ductwork for any visible gaps or disconnections.

This might involve checking duct connections in your attic, basement, or crawl spaces. Ensure that no insulation has fallen away and that no creatures have nested in the ducts. Animals and pests can cause damage to ductwork, leading to air leaks and contamination.

AC Shutoff Switch

The AC shutoff switch is another crucial component to check. Ensure it is not engaged, as this switch can inadvertently be turned off, cutting power to your AC unit. Additionally, check the AC drain pan for clogs.
