What is Maintenance?
Maintenance, otherwise known as technical maintenance, refers to a set of processes and practices which aim to ensure the continuous and efficient operation of machinery, equipment, and other types of assets typically used in business. Diligence in implementing an effective maintenance program is essential to the successful performance and longevity of machinery, assets, facilities, and entire businesses.

Types of Maintenance
Routine Maintenance
This type of maintenance, also referred to as preventive maintenance, is implemented on a fixed schedule and typically includes activities such as inspecting, cleaning, washing, replacing, and checking. It is typically performed in the downtime between shifts or on weekends to avoid affecting productivity goals. Routine maintenance has two objectives; to identify existing issues so they can be corrected ASAP and to prevent possible issues from becoming a reality through consistent care.
​
Planned Maintenance
Where routine maintenance may happen on a daily, weekly, or monthly basis, planned maintenance may be scheduled once per year or as needed. This is because planned maintenance is more time-consuming, expensive, and thorough—often requiring the services of a specialist. In the context of maintaining an air-conditioning unit, routine maintenance is taking out and washing the filters once per month, while planned maintenance is hiring an HVAC professional to check refrigerant levels, possible leaks, and measure airflow through the evaporator coil.
​
Corrective Maintenance
If during your routine maintenance inspection of a car you discover signs of severe wear-and-tear, you need to perform corrective maintenance. When computer or gauge readings for a machine show unusual, possibly hazardous anomalies, you need to perform corrective maintenance. Corrective maintenance pertains to the repairs and replacements necessary to get an asset back up and running at full power and optimal condition.
​
Predictive Maintenance
This maintenance type focuses on techniques used to determine the appropriate schedule for planned and corrective maintenance. Its primary goal is to predict, through a variety of testing methods, when a machine will start experiencing severe wear and tear so corrective maintenance can be scheduled without affecting productivity goals and before the machine breaks down.
