Preventative Maintenance

Your varied needs

The thermal systems that support your facility are comprised of various sub-system units that were originally engineered to work together as an integrated system.

For example, in the case of a building's HVAC system, which may be comprised of centrifugal chillers, condensers, pumps, roof top air conditioning units, exhaust fans, make-up air units, boilers, dehumidifiers, and automation systems etc. Despite originating from multiple suppliers, these units must operate in unison to effectively maintain occupant comfort within your facility. They must be seen as a whole.

Your building or production facility may also encompass designated specialized areas such as laboratories, clean room production areas and data centers, considered critical to your operation and requiring a high level of support.

With the sum of this equipment investment reaching upwards of hundreds of thousands of dollars, you require that the equipment equal or surpass its design life expectancy, that the units operate with minimal interruption and that their repairs be undertaken in an efficient manner. You realize that these objectives cannot be met without the presence of a proper preventative maintenance program.
