Commercial AC Repair & Maintenance Tips

The Benefits of Regularly Scheduled Commercial AC Repair and Maintenance

Commercial AC systems often run long and hard throughout the long summer cooling season. Your staff depends upon air conditioning; productivity is affected when temperatures fall below or rise above expected thresholds. Your customers and guests depend upon air conditioning; if given a choice, they will choose to frequent comfortable environments.

Since your AC is working so hard, it is essential to properly maintain and care for it. The system is designed uniquely for your building, with the latest technology (when installed), and precision component parts. With this system, you should be able to maintain temperature and humidity within your facility with a great deal of accuracy. While this system is not delicate, it does require regular maintenance.

Change the Air Filters.

Air filters remove airborne particles with every heating and cooling cycle; they work very efficiently and clean the air. Eventually, enough of these particles are collected to clog the filter. Dirty filters reduce the amount of air that flows through the air conditioner, reducing efficiency by up to 15%.

The clogged filter will also allow dust and debris to bypass the filter and deposit on various mechanical and electrical parts, further reducing efficiency. Some filters are reusable; others are meant to be replaced. These filters should be either cleaned or replaced at least every three months.

Regular Professional Tune-ups.

Commercial air conditioners vary in technology and size and should be cared for by technicians. A technician with the proper training and equipment should inspect, test, and clean the component parts.

• Most air conditioning systems use refrigerant gas under high pressure. When the pressure is released, the gas gets very cold. Air moves over the tubes containing the gas, cooling the air. Maintenance of the air conditioner includes checking the gas pressure. A loss of the prescribed gas pressure indicates a leak. The leak should be located and sealed before the gas can be replaced.
• Cooling coils will need to be carefully cleaned. The same refrigerant gas collects heat and moves it outdoor. However, the gas becomes very hot and must be cooled quickly. The coil allows air to move very quickly over the tubes containing the gas, cooling it in the process. Dirt and debris can also impede airflow, but this can have disastrous results. It is essential that the coils stay clean.
• Various electrical controls, sensors, and switches will be cleaned and tested. These components are the heart of your air conditioning system; without them, the system fails. Dust creates electrical resistance, so it must be removed. Age and use will lead to electrical component failure. Extensive testing locates failing parts so they can be replaced.
• Mechanical parts will also need to be cleaned and tested. Mechanical parts primarily move air. Dust can cake on moving parts, increasing their weight, and making them harder to move.

Admittedly, this description is simplistic, since the range of air conditioning systems is vast. However, it does demonstrate the complexity of systems and the need for professional Commercial AC Repair service. It also demonstrates the necessity of cleaning and testing your air conditioner system.
