And regular maintenance not only prolongs the lifespan of your unit but also helps you save on energy costs and avoid expensive repairs. So, here are some essential tips for keeping your air conditioning unit in top shape.

Air Conditioning Maintenance Tips

Air Filters

One of the most important maintenance tasks is regularly cleaning or replacing your air filters regularly. And dirty filters restrict airflow, making your unit work harder to cool your home. Moreover, this not only reduces efficiency but can also lead to overheating and damage. So, it’s recommended to check your filters every month and replace them every one to three months, depending on the type of filter and the level of use.


The evaporator and condenser coils of your air conditioning unit can collect dirt over time, which can reduce their ability to absorb and release heat. And cleaning the coils at least once a year is essential. So, you can do this by gently brushing off the dirt or using a vacuum with a soft brush attachment. Additionally, ensure the area around the outdoor condenser unit is free from debris, leaves, and other obstructions that could impede airflow.

Thermostat Settings

Ensure your thermostat is set correctly and functioning properly. And if you’re still using a manual thermostat, switch to a programmable or smart thermostat. Moreover, these devices allow you to set temperature schedules, which can help save energy when you’re not home. So, keeping your thermostat at a consistent temperature can prevent your unit from working too hard.

Condensate Drain

The condensate drain is responsible for removing the moisture your air conditioning unit extracts from the air. And over time, the drain can become clogged with dirt and algae, which can cause water damage and humidity issues. So, check the drain regularly and clean it with a mixture of water and vinegar to prevent blockages. Moreover, ensuring the drain is clear helps maintain the efficiency of your unit and prevents potential water damage.

Low refrigerant levels can significantly affect the performance of your air conditioning unit. And if you notice that your unit isn’t cooling as efficiently as it used to or you hear hissing or bubbling noises, it might be a sign of a refrigerant leak. So, it’s crucial to address these issues promptly by contacting a professional air conditioning contractor in Knoxville TN, as handling refrigerant can be dangerous and requires specialized knowledge.

Professional Maintenance

While there are many maintenance tasks you can perform yourself, having a professional technician inspect and service your air conditioning unit at least once a year is highly recommended. A professional can identify and fix potential issues before they become major problems, ensuring your unit operates efficiently. So, they can also check the refrigerant levels, inspect the electrical components, and clean the unit thoroughly.

Outdoor Unit

The outdoor unit, or condenser, needs adequate airflow to function properly,  ensuring that there are no obstructions such as plants, leaves, or debris around the unit. So, trim any vegetation at least two feet away from the HVAC system to allow for proper airflow. Additionally, check regularly for any damage to the unit’s fins and straighten them if necessary to ensure optimal performance.


Leaky ducts can significantly reduce the efficiency of your air conditioning system by allowing cooled air to escape before it reaches its intended destination. Look for damage or leaks in the ductwork and seal them with duct tape or mastic sealant. So, making sure that your ductwork is properly sealed can improve your unit’s efficiency and help maintain consistent temperatures throughout your home.


Proper insulation in your home can reduce the workload on your air conditioning unit by keeping cool air inside and hot air outside. And check the insulation in your attic, walls, and around your windows and doors. So, adding or improving insulation can help your unit run more efficiently and save you money on energy bills.

Insulation on Refrigerant Lines

The refrigerant lines that connect the indoor and outdoor units should be properly insulated to ensure efficient operation. And check the insulation periodically and replace it if it’s worn or damaged. So, proper insulation helps maintain the correct refrigerant temperature and prevents energy loss, improving the efficiency of your unit.

Maintaining your air conditioning unit is essential for ensuring it runs efficiently and lasts longer. And by following these tips and performing regular maintenance, you can keep your unit in top condition, save on energy costs, and avoid costly repairs.
