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.
