Air Conditioning System and Basic Diagnosis

Summer is the most unpleasant season in many parts of the world. Everyone looks out for easy and inexpensive ways to keep themselves and their houses cool and secure from the heat of the summer. However, it is not possible for everyone to enjoy the summer. One easy way to keep your rooms cool is benefitting from the best home air conditioning service available in your area.
Air conditioning systems have the ability to remove dust particles and all other types of allergens from the environment. There are people who are allergic to pollen, dust and other particles from the environment. Air conditioning systems help purify the air and protect you from allergic reactions and illnesses such as asthma.

Keeping your AC system safe
AC units have many filters that consistently work to keep germs away, dust and bacteria from working their way into the enclosed rooms of a house. Over a period of time filters need to be cleaned. It is not only necessary to clean them so that they function effectively but also to ensure that these filters do not get permanently damaged and be beyond repair. Also, so you can ensure that you get cool and clean air.
Indoor air quality is important for any building whether it be residential or commercial. A poorly working unit could mean even bigger problems like mold. Mold problems should be remediated immediately if found in your home. Not only is mold a health threat but it can literally deteriorate the foundation of a building.

Air Conditioning System Diagnosis

So, now is the time to ensure that your equipment is in tip-top shape. If you fail to maintain it, your cooling system will suffer a steady decline in performance while your energy use and utility bills will increase.
While there are some maintenance jobs that you can do to prolong the life of your equipment and keep it running at peak efficiency, other jobs are best left to the professionals. Some of the simple things that any homeowner can do include:

·0 Filters should be routinely cleaned or replaced. (some are reusable while others must be replaced).
·1 Ensure that the outdoor condensing unit has adequate airflow by checking that the area around the unit is cleared of debris and that foliage is trimmed back at least two feet.

Other maintenance tasks that are best left to a trained technician are as follows:

·2 The evaporator coil should be checked every year and cleaned as necessary – dirt reduces air flow and insulates the coil, reducing the cooling ability of your air conditioner.
·3 Outdoor condenser coils can become dirty as well and should be cleaned.
·4 Aluminum coil fins on evaporator and condenser coils outdoor should be checked and, if necessary, straightened to ensure that airflow is not blocked.
·5 Supply and return air ducts should be checked for leaks. A professional service technician can detect and correct duct leaks that could allow cool air to leak out and hot air to leak in, wasting an enormous amount of energy.
·6 Checking to ensure the proper working pressures in the refrigeration circuit. A qualified service technician will have the tools and experience necessary to determine that your cooling system is operating as it should be.


Every product suffers depreciation over time. A two-year-old air conditioner would most certainly not have the same efficiency as one that is completely new. However, what you can do is take care of the machine to reduce the extent of depreciation. There are many reasons why keeping up with your air conditioner maintenance is important. Not only does a poorly working unit make your utility bills higher, but it also puts your health at risk.
