Air conditioning is essential to modern living, especially in hot and humid climates. However, many people have questions about their AC system, from how it works to how to keep it running efficiently. In this article, we’ll answer some of the most common air conditioning questions.

How Does Air Conditioning Work?

Air conditioning removes heat and moisture from the air in your home, leaving you with cool, dry air. The process starts with the evaporator coil, which is located inside your home. The coil contains refrigerant, a liquid that absorbs heat from the air as it passes over the coil. The refrigerant then evaporates into a gas, carrying the heat away.

The gas is then sent to the compressor, which compresses it into a high-pressure gas. This gas is then sent to the condenser coil located outside your home. As the gas cools, it condenses into a liquid, releasing the heat it absorbed. The liquid refrigerant then returns to the evaporator coil to start the process over again.

Why Is My Air Conditioning Not Cooling?

There are several reasons your air conditioning may not be cooling properly. One common issue is a dirty air filter. When the filter is clogged with dust and debris, it can restrict airflow and reduce cooling efficiency. Check your filter and replace it if it’s dirty.

Another common issue is a refrigerant leak. If your AC is low on refrigerant, it won’t be able to cool your home effectively. You’ll need to call a professional to locate and repair the leak and recharge your system with refrigerant.

Finally, your AC may not be cooling properly if it’s not sized correctly for your home. If your system is too small, it won’t be able to keep up with the cooling demands of your home. If it’s too large, it will cycle on and off frequently, which can reduce efficiency and cause wear and tear on the system.

How Often Should I Change My Air Filter?

You should change your air filter every 1-3 months, depending on how often you use your AC and the level of contaminants in your home. You may need to change your filter more frequently if you have pets or allergies. A dirty filter can reduce airflow, which can cause your AC to work harder and increase energy usage.

How Can I Improve the Efficiency of My Air Conditioning?

There are several ways to improve the efficiency of your air conditioning system. One is to keep your AC well-maintained. Schedule annual AC maintenance with a professional to ensure your system runs at peak efficiency. During the maintenance visit, the technician will clean and inspect your system, replace worn parts, and check refrigerant levels.

Another way to improve efficiency is to upgrade to a programmable thermostat. This will allow you to set your AC to turn on and off at specific times, so you’re not cooling an empty house. You can also set the temperature higher when you’re away from home to save energy.

Finally, make sure your home is well-insulated and sealed. This will reduce the hot air entering your home and keep cool air inside.

Should I Repair or Replace My Air Conditioning System?

This depends on the age and condition of your AC system. If your system is more than ten years old and requires frequent repairs, replacing it with a newer, more efficient model may be more cost-effective. A professional AC technician can help you determine whether repair or replacement is the best option for your system.


Air conditioning is an essential part of modern living, but it’s important to understand how it works and how to keep it running efficiently. Following these tips and scheduling regular AC maintenance can keep your home cool and comfortable while minimizing energy usage and costs.
