(NC)—Do you rely on central air conditioning to make the summer's heat and humidity more bearable? If 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:

• Filters should be routinely cleaned or replaced. (some are reusable while others must be replaced).
  
  
  
• 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.
  
  

• The evaporator coil should be checked every year and cleaned as necessary – dirt reduces airflow and insulates the coil, reducing the cooling ability of your air conditioner.
  
  
  
• Outdoor condenser coils can become dirty as well and should be cleaned.
  
  
  
• Aluminum coil fins on evaporator and condenser coils outdoor should be checked and, if necessary, straightened to ensure that airflow is not blocked.
  
  
  
• 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.
  
  
  
• 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.
  
  

A Quick Note From The Publisher... If you like the article above, you may be interested in the following article which is also related to HVAC... Cool Air Summer’s coming and things are of course getting hot. It is time to cool your homes and work places with a new air conditioner or swamp cooler. Along with air conditioning and swamp cooling, however, come higher energy costs. Conservationists suggest planting trees around your house or office to cool it with the shade. This will save you money on your energy bill, and keep the place nice and cool. For those who do not have the option of planting a tree to cool off in the shade, or who do not have the time to wait for a tree to grow large enough to cover them in shade, there are more efficient air conditioners and swamp coolers. It may be worth it to do a little research to find a more efficient air conditioner for your home or office; one which cools a larger area for a lower cost. Air conditioners have a standard energy efficiency rating or EER. Air conditioners are often rated by the number of British Thermal Units (Btu) of heat they remove per hour. Almost all new air conditioners will come with and/or be advertised with ratings of their cooling and energy efficiency in the measures noted above. You will need an air conditioner that will sufficiently keep a room cool while using as little energy as possible. A number of factors can affect a rooms temperature, including the size of the room, the height of the ceiling, the insulation in the walls and the ceiling, heat generated by appliances and occupants in a room, and as noted before, whether the home, room, or office you are attempting to cool is shaded or in the sun. There are two main groups which publish calculation procedures for sizing air conditioners for your room, home or office: the Air Conditioning Contractors of America (ACCA) and the American Society of Heating, Refrigerating, and Air...
