How to Maintain Your Air Conditioner

An air conditioner’s coil, filter and fins need regular maintenance so the unit can be effective and efficient throughout the year. If you neglect proper maintenance, your unit will decline in performance and the energy consumption will increase.  If you don’t want the extra cost of having to buy another air conditioner, you need to take extra measures to prevent your unit from getting damaged. Since you are very technical and is connected to the world of technology, it will be easy for you to follow the steps needed to maintain your unit.


This is the most important part to maintain because the efficiency of your air conditioner depends on it being replaced regularly. If your filters become clogged or dirty, it will hinder the normal airflow and reduce your system’s effectiveness. When the normal airflow is blocked, the air that bypasses the filter can carry dirt straight to the evaporator coil. It can also damage the coil’s capacity to absorb heat. Replacing dirty filters will lower your energy consumption by 5 to 10%

Some filters can be reused while others are made to be replaced. These air conditioners are available in different types and effectiveness. As a general rule, you can replace your unit’s filters every month or every 2 months if you don’t use it everyday. Also, if you have pets inside the house, you need to replace it more frequently since pet hair go inside the unit and clog the unit.


The evaporator coil and condenser are the ones that collect the most dirt overtime. They are still dependent on the air filter because it prevents them from spoiling faster. However, no matter how many times you replace the filter, your evaporator coil will still be dirty over the years. Because of this, the air flow is reduced and the coil becomes insulated. You need to avoid this by checking the coils annually and cleaning it.

The coils will collect even more dust if the environment that it’s in is dirty as well. Minimize the dirt that is near the unit. If you clean the area around the condenser coil and remove all debris as well as trim the foliage at least 3 feet, it will help the air to flow around the condenser.


These fins are found on the evaporator and condenser coils. They are bent very easily and results to the airflow being blocked because of the coil. There are tools like a fin comb that can restore this comb into good shape.


You need to use a stiff wire through the air conditioner’s drainage every now and then. Clogged channels cause the unit’s ability to reduce humidity to go down.


You need to take a look at the seal between the air conditioner and the frame of your window to make sure that it still creates contact with the metal case of your unit. This seal can be damaged by moisture that lets the cool air escape.
