Taking Care of Your Air Conditioner

If you have an air conditioner at home or in your office, you should know that it requires regular maintenance for it to function effectively and efficiently through the course of its lifetime. Failure to get the necessary maintenance for your AC unit will result in a steady decline in its performance and its energy use to increase.


Here are some of the most important things you should remember when maintaining your AC unit:



The most important maintenance task that you should pay close attention to if you want to ensure the efficiency of your AC unit is to routinely clean or replace your furnace filters. Dirty and clogged filters block normal airflow and can, therefore, reduce the system’s efficiency significantly. Remember, normal airflow that is obstructed will allow the air that bypasses the filter to carry dirt directly into the evaporator coil. This, in turn, can impair the coil’s heat-absorbing capacity. If you want your AC unit to reduce its energy consumption by 5% to 15%, then you should replace dirty and clogged filters with a clean one.


EVAPORATOR COIL CONDENSATE DRAINS – (the coil that is installed in your home’s supply air duct)

From time to time, you should pass a stiff wire through your AC units drain channels to ensure proper drainage of the evaporator condensate collector pan.  Under high humidity conditions, the condensate collector pan could overflow. This may cause damage to your furnace components and home.



Your air conditioner system contains 2 coils.  The evaporator coil is located in the home’s supply air duct just after the furnace.  The condenser coil is located in the A/C unit that is installed outside.

This evaporator coil can collect dirt over time. A clean furnace filter will help prevent the evaporator coil from soiling quickly. You can, however, still expect the evaporator coil to collect dirt in time. This dirt will then reduce airflow and insulate the coil, thus reducing its ability to absorb heat. This may also result in the evaporator coil freezing up which may reduce airflow and cooling to your home.  If you want to avoid this problem, you should have your evaporator coil checked every year and have it cleaned as necessary.


Outdoor condenser coils can also get dirty if the outdoor environment is dirty or if there is foliage nearby. It is easy to spot the condenser coil and to see if dirt is collecting on its fins. Always ensure that foliage, grasses, weeds, etc. are not blocking the condenser coils, reducing their efficiency.



The aluminum fins found on condenser and evaporator coils are easily bent and thus, can also block airflow through the coil. The fins, however, can be combed back into nearly their original condition. Ask one of our experts about this!



It is also a must to inspect the seal between the air conditioner and the window frame. Make sure it comes in contact with your unit’s metal case. Remember, moisture can damage the seal, letting cool air to escape from your home.  Clean the filter on the unit as required.  Also, inspect and clean the unit’s coils if necessary.



Remove/clean the filter and coils in the unit located inside your living area. Also, check the coils on the exterior condenser unit for cleanliness.



If your air conditioner unit needs more than the regular maintenance, then make sure to hire one of your expert technicians. A well-trained technician can find and fix any problems in your air conditioning system. Our experts are just one call away!
