Proper Maintenance
The operation of your Central Air Conditioner system is very similar to a vehicle: its efficiency greatly depends on the way it is operated and maintained. Vehicles last longer and consume less fuel when they receive the proper care and are driven with moderation. The same happens to an air conditioner.

To always obtain the best temperature at the least electrical cost and to extend the useful life of your system, the following recommendations must be followed:

Clean filters and heat exchangers once a month. Do not allow the use of any type of chemical products since most of them react to aluminum and destroy it. We recommend the cleaning to take place only and exclusively with pressure water. Air Conditioning systems do something else besides cooling the air. They reduce the environment humidity and remove dust and dirt when air passes through their filters. When the filters and heat exchangers are plugged, the system will diminish its performance and increase its electrical consumption. Furthermore, we recommend to replace the filters once a year.


Keep the thermostat at a steady temperature and out of reach of children and strangers. Find the comfortable level within your environment and keep it all the time. When arriving at the place and finding the equipment turned off and, therefore, a hot environment, turn it on and do not change its temperature. Setting it up at a lower temperature is not going to produce more amount of cool air. On the contrary, there will be a greater possibility to forget to set it back to its usual temperature making the system work longer to reach a temperature lower than the required with the consequence of an additional cost in electricity.


Do not allow the original design of the electrical panel and manufacturer setting of pressure controls, expansion valves and time delays of your equipment to be altered by anyone. They have been carefully analyzed, designed and tested by the plant engineers to make possible for the components assembly of your air conditioner to work perfectly. If by problems with your power supply you would add any type of additional protection, it must be placed outside the equipment or be requested as an additional component to be installed in factory. It is a common practice among technicians when performing the installation and not being able to reach the adequate pressures in the system, to try to modify the equipment or any of its components. In most of the cases, when this happens, the problem is spotted in some point where the air or refrigerant flow is being restricted, humidity or dirt is located within the system or the pipe diameters are not the adequate. Remember that any modification to your Air Conditioner equipment will leave the warranty without effect.


Do not turn on/off the equipment several times during the day because it produces a rapid wear of its components. Besides, most of the electricity is consumed when turning it on. If your equipment has been functioning to cool and dehumidify the environment, turning it off and opening doors and windows will let the cool and dehumidified air go out, letting hot and humid air and dust get in, which is unfavorable at medium-term and produces condensation on the supply grilles. The more insulated against heat, humidity and dust is the environment, the more efficient will be the performance of your equipment.

Have specialized personnel perform a general inspection of your system at least four times a year. The main aspects to be checked are the refrigerant pressures, temperatures, amperage, motors and compressors lubrication, adjustment and balance of fans, wheels and the entire driving system in general, air flow through the coils, insulation of the suction line, condition of the condensate collecting pan and drainage. It will allow them to correct any irregularity before major damages occur.

Furthermore, specialized personnel should carefully check, at least once a year, all duct work in order to detect the presence of air leaks in joints, ensure that the sections are still properly insulated and to remove accumulated dirt or possible spores built within.


Refrigerant pipes, their connections and supports and any other element of the system must be constantly checked with the purpose of spotting any leakage. The existence of oil spots is a clear indication of refrigerant leakage within the system.


Even when performing tests, access panels of the condensing unit must be sat and adjusted while the unit is operating. Otherwise, air flow through the condenser will be reduced, increasing the discharge pressure until the high pressure control or the compressor is shut due to an overcharge.
