3 Quick and Easy Air Conditioner Maintenance Tips

Air Conditioner Maintenance Tips - LG Home Comfort

An air conditioning system will only last as long as how well it is maintained. Scheduling periodic maintenance for your air conditioning unit will ensure that it will remain in good working condition for a long time, requiring fewer replacement parts and lower maintenance costs in the long run. 

Knowing what to look for when it comes to air conditioning maintenance is the key to ensuring that small problems can be fixed before they become serious. Regularly checking the condition of your air conditioning unit will help you detect problems and prevent them from becoming unfixable. 

3 Quick and Easy Air Conditioner Maintenance Tips

As a homeowner, you have to be prepared to maintain your air conditioning system (and your other HVAC machines) from time to time. Here is a short checklist of what you should do when you do routine maintenance on your air conditioner. 

1) Examine the Thermostat

The first thing you should do is to take a look at the thermostat. This is probably the most straightforward and easiest step in the maintenance routine. Check that the temperature displayed on the thermostat matches the temperature in your home.

If you have an old air conditioner, your model may not have a smart thermostat. This is one of the parts you may want to consider having replaced. A smart thermostat will have features that a traditional one doesn’t. It will let you customize the system settings, such as adjust the thermostat’s temperature during times when there is nobody at home. You may also be able to set an automatic timer to cool the house half an hour before everybody goes home. This way, you will be assured that your home will have a comfortable temperature when you arrive.

2) Check the Air Filters

The next step is to check the air filters in your air conditioning unit. You may refer to your user’s manual as to where your air filters are found. Your air conditioning unit may have either a reusable filter or one that you replace. 

If you see that the filter is full of dust, you need to either replace or clean it. Keep in mind that if the layer of dust becomes too thick, it will restrict airflow and make the air conditioner less effective at doing its job.

3) Clean the Outside of the Unit

After replacing or cleaning the dust off of the air filters, you also need to make sure that the outer shell of the unit is clean and free of dirt. It is also important to look at the portion of the air conditioning system that is located outside of the house. Make sure there are no leaves, branches, or anything else that may cause obstructions to airflow.

Note: If you do not feel confident to do the task on your own, never hesitate to call a professional. That way, you can watch how they do a routine maintenance check on the machine. After observing them, you will be able to do the job on your own next time.


Regularly checking your air conditioning system for minor problems will prevent the machine from needing any major repairs in the long run. However, checking your air conditioning unit for damage and parts that need minor repairs requires a certain amount of knowledge and skill. If you do not know how to properly diagnose problems with your air conditioning, you can always call an air conditioning repair and maintenance service. They will be able to detect any potential problems with your unit and repair them before they get out of hand.
