Can I DIY My Air Conditioner Maintenance?

Doing the maintenance work for your air conditioner can be an attractive option for some homeowners, mainly because of the money it can save. However, it’s also important to note that inexperienced DIYers trying to perform HVAC maintenance are prone to making errors, which makes it possible to damage vital components and incur even bigger expenses.

While there are air conditioner maintenance tasks that you can handle on your own (such as cleaning and changing the filters), it’s still best to hire a professional to do the more complex tasks. Here are a few reminders from AC installation experts which can help ensure your air conditioner is maintained properly.


Routine cleaning and replacement of the filters will help ensure the efficiency of your air conditioning unit. Clogged, dirty filters tend to block normal airflow and reduce the system’s efficiency, which is why you should regularly monitor your AC filters.

Condensate Drains

Make sure the condensate drains aren’t clogged. Otherwise, your air conditioner may be unable to reduce humidity, which can result in excessive moisture that could potentially discolor your walls or carpet. This may also lead to some problems that will require AC repair.


The evaporator and condenser coils are responsible for collecting dirt over the lifespan of your air conditioner. An AC filter typically prevents the evaporator coil from becoming dirty too quickly. As a good rule of thumb, you should check this coil every year and clean it as often as necessary. Meanwhile, outdoor condenser coils can become very dirty depending on how dusty the environment is and if there’s foliage nearby.
