At the end of a hot Southern summer, your air conditioning has been working hard for a while, and the workload takes a toll on the system. Even though fall is finally knocking on the door, it’s important to follow the right maintenance steps so your AC is still in good condition when spring rolls back around. Here’s a closer look at what to care of.

End-of-Summer AC Maintenance Checklist

1. Change the Filter

If the filter in your unit is clogged, airflow is reduced, forcing the unit to work harder to compensate. This increases your bills and makes it more difficult to get your home to a comfortable temperature.

The filter should be changed at least every three months—and more often if you have long-haired pets or if anyone in your home has allergies. The end of summer is a good time to change the filter after pollen and other contaminants have built up over the previous months.

2. Be Aware of Unusual Sounds & Smells

If your air conditioning unit has been overloaded during hot weather, it might start to behave strangely. This includes unusual noises, such as banging and rattling that are caused by loose parts. High-pitched sounds could indicate a refrigerant leak, a pressure buildup, or a problem with the fan motor bearings.

Unpleasant smells from the AC are possible as well. For example, a musty odor could signal mold on the evaporator coil. A burning scent may point to an issue with wiring or an overheating motor.

3. Schedule Professional Maintenance 

A professional will inspect and fix parts of the system that are difficult or even dangerous to reach for someone who isn’t trained. A tuneup will include checking the electrical connections, lubricating moving parts, and clearing the condensate drain line, which is important to avoid leaks and mold. They’ll also spot minor problems before they turn into major future expenses and ensure the highest level of energy efficiency possible in your system.

4. Check Your Outside Unit

There should be no obstructions close to your outdoor AC compressor because they block airflow, reduce efficiency, and could even damage the system. If the area isn’t cleared during the summer, the extra debris that comes from falling leaves in the autumn may cause additional problems. Clean up the immediate surroundings and cut back any branches that hang nearby.
