Troubleshooting When Your AC Won't Cool

Learn how to troubleshoot when your AC won't cool. Here are some common causes and tips for diagnosing the problem.

Troubleshooting When Your AC Won't Cool

It's a hot summer day, and you're relying on your air conditioner to keep you cool. But when you turn it on, nothing happens. You may be feeling frustrated and helpless, but don't worry - you can troubleshoot the issue and get your AC back up and running. In this article, we'll walk you through the steps of troubleshooting when your AC won't cool. We'll cover the most common causes for AC not cooling, and how to fix them.

So read on to learn what to do if your air conditioner isn't doing its job.

Common Causes of an AC That Won't Cool

Clean or Replace the Air FilterA dirty air filter can reduce airflow and cause your air conditioner to work harder, leading to an inefficient cooling system. Check your air filter and clean or replace it if necessary.

Clean Condenser Coils

The condenser coils are responsible for cooling the refrigerant that circulates throughout your AC. If these coils become blocked with dirt, dust, or other debris, they won't be able to do their job properly, resulting in decreased cooling performance.

Refrigerant Leak

Leaking refrigerant can cause your AC to work less efficiently. If there's a leak in your system, it can reduce the amount of refrigerant available to cool the air, resulting in an AC that won't cool.

Malfunctioning Compressor

The compressor is responsible for pressurizing the refrigerant and circulating it throughout the system.

If the compressor is malfunctioning, it won't be able to circulate the refrigerant properly, leading to an AC that won't cool.

Incorrectly Calibrated Thermostat

The thermostat is responsible for sensing the temperature in your home and adjusting the AC accordingly. If the thermostat is not correctly calibrated, it may not be able to sense the correct temperature and could result in an AC that won't cool.

Common Causes of an AC That Won't Cool

When troubleshooting an AC that won't cool, here are some common causes to consider:Clean or replace the air filter: The air filter in your AC system should be regularly changed or cleaned to ensure good air flow and optimal performance. If the air filter is clogged, it can restrict air flow and cause the AC to not cool as effectively.

Clean condenser coils:

The condenser coils are responsible for transferring heat from the refrigerant in the AC system. If these coils become dirty, they can't absorb heat as effectively, which can make it difficult for the AC system to cool the air.

Refrigerant leak:

If there is a leak in the refrigerant line, this can cause the AC system to not cool as effectively.

It is important to have a professional inspect your system for any leaks and repair them if necessary.

Malfunctioning compressor:

The compressor is responsible for compressing the refrigerant in the AC system. If the compressor is malfunctioning, it can cause the AC system to not cool as effectively.

Incorrectly calibrated thermostat:

The thermostat controls the temperature in your home and if it is not properly calibrated, it can cause the AC system to not cool as effectively. It is important to have a professional inspect and calibrate your thermostat if necessary.

Common Causes of an AC That Won't Cool

When troubleshooting an AC that won't cool, there are several common causes to consider. These include:- Cleaning or replacing the air filter;- Cleaning the condenser coils;- Refrigerant leak;- Malfunctioning compressor;- Incorrectly calibrated thermostat.
