To maintain proper functioning of a commercial air conditioning systems, regarding dependability and economical operation, yearly maintenance is required. This entails simple procedures to obtain peak performances and sufficient comfort. Proper maintenance also reduces the monthly power bills significantly since air conditioners consume a lot of power. A commercial air conditioning system is estimated to lose about five percent of its efficiency yearly without proper maintenance procedures. Its useful operating life is also doubled, and most of the health risks associated with poor air quality are greatly minimised.
To maintain efficiency and lifespan of a commercial air conditioning system, professional maintenance procedures are required. The general ones are:
Before dismantling any of the access panels or try to start any maintenance operations, you should be sure to turn off all electrical power supply to the unit. You should also keep in mind the probability of there being more than one power supply connection.
The majority of the metallic components and housing have sharp edges that can lead to serious injuries. With this in mind, you should be very careful when handling the system.
All the safety precaution procedures, personal protective equipment or all state and local codes should be used, as described by the equipment’s manufacturer.
If something or action looks dangerous or potentially harmful, you should seek professional advice.
The return air filter in your commercial air conditioning unit should be checked after about two to four weeks. Keeping the filter clean is a simple way of keeping the system run smoothly because this efficiency and lifespan is largely compromised. Improperly cleaned filters also bring the aspect of high electricity bills into play. Since operating conditions are different to different units, the duration of replacements is based on visual inspections. If the entire surface has a film of dirt, then it is time for a replacement. If the type of filter in question is the reusable type, it can be washed with soap and water on both sides, the clean side and the dirty side. It should be left to dry completely before installing it back.
Any debris from the condensing unit should be cleared, for example, leaves or plants for outdoor condensing units, to avoid blockages to the coil which could lead to expensive repairs. Like stated before, the unit should be turned off at the thermostat and breaker before dismantling the system. The issue of sharp metal parts inside the unit should be taken into consideration to avoid injuries during maintenance.
The outdoor unit should be checked to maintain a level position. This is done to make sure the compressor and motor fans don’t wear out rapidly because it will lead to costly repairs or component replacements. The levels should also be maintained to help drain water out of the air conditioning unit. To even up, a wooden or metal shim can be placed under one of the uneven sides. If this does not help, a professional should be called to help.
This is done by washing with water and soap once a month during the cooling season. If the commercial air conditioning unit is located near the coast, all exposed surfaces should be washed too including the coil.
The return air should be cleaned free of dust and obstructions. This can be done using a vacuum cleaner, and a soft brush and dust is removed both on the inside and outside of the grill. The unit is turned off first to avoid contamination of the air supply.
Professional preventive commercial air conditioning maintenance is vital to keep the air conditioning system up and running for a long life period.
