(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... Home Insulations A comfortable home that is warm in winter and cool in summer is a major priority for most homeowners and they pay for it! Heating and cooling account for approximately 70 per cent of the average household’s energy costs. That’s when home insulation becomes essential in reducing one’s utility bills. Many of the existing homes in the United States are not insulated to the optimum level. Older homes usually consume more energy than newer homes, resulting in higher heating and air-conditioning bills. Even if one owns a new home, adding insulation helps save money and increase the resale value of the house. Insulation makes one’s house more comfortable by helping to maintain a uniform temperature throughout the house. Walls, floors and ceilings tend to remain comparatively warmer in the winter and cooler in the summer. Insulation can also act as a sound absorber, keeping noise levels down. It is usually possible to add insulation to any type of a house. One may be able to do the job by oneself, if the structural framing is accessible. For instance, insulation can be done in unfinished attics or under the floor over an unheated space. Or one may prefer to hire an insulation contractor. In either case, it is important to choose and install the home insulation correctly. When installing home insulation, one has to keep in mind that the amount of energy one conserves will depend on several factors like the local climate; the type and the efficiency of the heating and cooling systems; the size, shape, and construction of one’s house; the living habits of the family; and, the fuel one uses. Energy conserved is definitely money saved and the annual savings will increase if utility rates go up. Insulation provides detailed information on Insulation, Foam Insulations,...
