Rosemark has been a leader in providing quality work, exceptional health and safety performance, and overall cost effectiveness for the past 17 years.   Office buildings, schools, corporate headquarters, shopping malls, call centers, industrial, manufacturing and special use complexes are some of the types of properties that our company provides value added HVAC Maintenance services for our customers.


Basic HVAC Maintenance Services Include:


Preventive Maintenance – regularly scheduled work performed on equipment, machinery, or systems that ensures safe, reliable, and continued operations; and to preclude unnecessary breakdowns; and maximize the life expectancy of the equipment, machinery, or systems.  Rosemark’s preventive maintenance includes, but is not limited to, adjusting, testing, repairing, replacing, greasing, oiling, cleaning, and painting the various equipment, machinery or systems.

Corrective Maintenance – the type of unscheduled work required to prevent a breakdown of a piece of equipment, machinery or system or put the equipment, machinery or system back in service after a breakdown or failure.

Predictive Maintenance –  the type of work to be performed on equipment, machinery or systems that may be deemed necessary to perform from the data derived from nondestructive testing technologies such as infrared, acoustic (partial discharge and airborne ultrasonic), corona detection, vibration analysis, sound level measurements, oil analysis, and other specific online tests. The data of tours, watches, logs or other monitored areas may also be used as Preventive Maintenance techniques. Predictive maintenance techniques help determine the condition of in-service equipment in order to predict when maintenance should be performed. This approach offers cost savings because tasks are performed only when warranted.

The main value of Rosemark’s Predictive Maintenance is to allow convenient scheduling of corrective maintenance, and to prevent unexpected equipment failures. The key is “the right information in the right time”. By knowing which equipment that needs maintenance, the maintenance work can be better planned (spare parts, people etc.) and what would had been “unplanned stops” are transformed to shorter and less “planned stops” thus increasing plant availability. Other values are increased equipment life time, increased plant safety, less accidents with negative impact on environment, an optimized spare parts handling, etc.
