To ensure effective operation of air conditioner throughout years constant maintenance is absolutely required. Without it, the air conditioning performance might decrease and you might face higher energy bills because of higher energy use.

The simplest task that everyone can do themselves is to make sure your air conditioner filters are clean. Dirty and clogged filters block airflow and push your AC to work harder. Consequently, your system’s efficiency drops significantly. Furthermore, the filter may pass dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity.

Note that not all filters are reusable. Some of them must be changed at a certain time. It should be cleaned or replaced every month or two during the cooling season or more often if the AC is used constantly. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.

Also, look for the self-cleaning air conditioners, like some NØRDIS models.

If you been using same air conditioning unit for a while now you should also get a closer look to air conditioner coils. Even if you clean filter regularly, over a long-term evaporator coil and condenser coil will get dirty. It will affect airflow and insulate the coil by diminishing its ability to absorb heat. To prevent that clean evaporator coil every year.

You should also take care of outdoor condenser coils. Especially if you live in an area where the outdoor environment is dusty or if there is foliage nearby. Clean the area around outside unit: clean dirt and debris and trim the foliage to at least 0,6m to ensure good airflow around the condenser.

To take care of the aluminum fins on evaporator and condenser coils use a special tool called “fin comb”. These aluminum fins can easily bend and disrupt airflow through the coil.

Another thing that you can take care of yourself is clean drain channels. Drain channels helps to maintain the right amount of humidity. To prevent clogged drains and discoloration of walls or carpet by moisture occasionally pass a stiff wire through the units drain channels.

If you think you AC needs a deeper look, consulting with NØRDIS experts would be your best bet. An experienced specialist can help you check for the correct amount of refrigerant, check for leaks, measure airflow through the evaporator coil, inspect electric terminals and most important parts of your AC, as well as consult you on how to maintain your air conditioner unit in the future.
