Frequently Asked Questions
Frequently Asked Questions
Common inquiries regarding contract scopes, SLAs, compliance audits, and onboarding.
Under UK regulations, commercial refrigeration or air conditioning equipment containing fluorinated greenhouse gases above statutory thresholds requires regular leak checks and certified logbooks. We manage this entirely.
We recommend quarterly inspections for commercial AHUs to change filters, inspect drive belts, sanitize coils, and verify airflow volumes to ensure healthy indoor air quality.
