Auditors scrutinise HVAC documentation more heavily than almost any other discipline.
ISO 14001 requires demonstrable environmental management of energy-intensive plant — HVAC included.
Auditors typically request the latest TM44 certificate, F-Gas leak logs, refrigerant register, and PPM service reports.
AccuTemp issues every client a digital compliance pack each year, structured for ISO submission.
TM44 inspections are legally required every 5 years for buildings with >12kW of cooling capacity.
F-Gas leak checks are legally required based on CO2 equivalent charge — not just system size.
