PREVENTATIVE 
MAINTENANCE

Service frequency depends on system type and usage. For most commercial sites, servicing is required quarterly or biannually, while higher-load environments (like schools or gyms) may need more frequent visits. CMG tailors each maintenance plan to the building’s specific needs and compliance requirements.
