"Irvin Wing" (2019-05-11)

For an AC to provide you utmost cooling and keep functioning properly, it is crucial that it has a regular maintenance schedule. Yes, this may sound not-so-important and you may push "air conditioning maintenance" at the last of your to-do-list. But you will be amazed to know that regular cleaning and maintenance of air conditioning can save you lot of money and will also extend the life of your HVAC unit.

Why Is It Necessary To Service Your Air Conditioning?

Air conditioners are only used seasonally; they are hardly used throughout the year. This is the reason that ACs end up collecting dust and debris during operation, which prevents it from providing utmost cooling. For this, AC filters, coils and sửa chữa điều hòa fins should be maintained regularly.


Dirty and clogged filters block normal airflow and reduce the efficiency of the system. With normal airflow blocked, the filter may carry dirt directly into the evaporator coil. This can actually impair the coil's heat-absorbing capacity, as well. However, if you hire a local heating and air conditioning company to replace the dirty, clogged filter with a clean one, it can lower the air conditioner's energy consumption by 15%.

Some types of filters are reusable, while others should be replaced. During the season, you should clean or replace the filters every month or two. Filters need more frequent attention, if the air conditioner is subjected to dusty conditions, is in constant use, or you have furry pets at home.


A clean filter prevents the evaporator coil from soiling quickly. However, the evaporator coil will still collect dirt over a period of time. This dirt reduces airflow and insulates the coil, thus decreasing its capability to absorb heat. This is the reason, it is advisable to hire a local heating and air conditioning company for checking the evaporator coil every year and clean it as necessary.


The aluminium fins on condenser and evaporator coils are easily bent and can block airflow through the coil. Air conditioning experts use a tool called "fin comb" to comb the fins back into nearly original condition.

The drain channels should also be cleaned regularly by passing a stiff wire. Clogged drain channels can prevent a system from reducing humidity, thus causing the resulting excess moisture to discolor carpet or walls.
