Preventative Maintenance That Can Be Done Safely on Your Enclosure Air Conditioner

With budget being an important thought in your mind, regular preventative maintenance on your electrical enclosures should be a consideration. Avoiding breakdowns can help keep your spending within reason, freeing up some room in your budget for other expenses. Keeping your equipment running well can also keep your warranty intact. Here are a few maintenance activities that you can perform on the air conditioner, to keep it running well and trouble-free.

Condenser Filters

Air conditioners require regular cleaning of the condenser air inlet filter. Wash the filter often, if washable, using proper cleaning compound and back flush the dirt out, or replace if not washable, whenever it appears physically dirty.  Restriction to the flow of air over the condenser coil will degrade the performance of the equipment, cause it to overheat, reduce cooling and can damage the compressor.

Condenser Coils

If your electrical enclosure is located in a particularly dirty or harsh environment in your facility, the condenser coil may become dirty and cause your air conditioner to lose efficiency. This can lead to either overheating in the air conditioner or diminished cooling capacity inside your electrical enclosure. By cleaning your condenser coils, you can extend the life of your air conditioner and keep the cooling capacity at top level.

To clean the coils, perform a backflush cleaning with a commercial cleaning compound. Then, give a proper backflush rinsing. The use of acid wash is highly discouraged because it will shorten the lifespan of the coils.

Condenser and Evaporator Fans

The sealed ball bearing fans are designed to be highly efficient as well as require no maintenance. The fan blades, however, will need to be cleaned regularly for peak performance.


The compressor provided with your electrical enclosure and air conditioner package is not only quiet and has low-vibration, it is maintenance free as well. If the compressor does begin to overheat, there is a thermal overload protection device installed to prevent damage. In the event a thermal overload device fails, it is recommended to return the air conditioner for warranty repairs.

Refrigerant Lines

Along with the compressor, repairs on the refrigerant lines are also recommended to be done by a qualified professional. As the lines are thoroughly leak-checked prior to shipping, any issues should be addressed by a professional refrigerant technician.

Even though there are no preventative maintenance tasks to perform for some of the components in your air conditioner, it’s still important to keep everything properly cleaned. A well-maintained and clean electrical enclosure will operate as intended, and keep your operating expenses where you want them to be.
