Reliable AHUs are central to occupant comfort, IAQ (Internal air quality), and regulatory compliance. Unplanned failures can shut down areas of your building, disrupt operations, and increase costs. ARC Facilities provides structured, SFG20‑aligned AHU maintenance contracts designed to prevent downtime, optimise energy use, and extend asset life—supported by rapid emergency response and clear, auditable reporting.
For hospitals, councils, offices, and residential blocks, Air Handling Units (AHUs) are mission‑critical. A structured maintenance contract prevents unplanned downtime, keeps indoor air quality on‑spec, and supports compliance frameworks like SFG20. ARC Facilities delivers SFG20‑aligned AHU servicing with flexible visit frequencies, transparent reporting, and a rapid response capability across London, Essex, and Kent.
We tailor contract frequencies to your assets and risk profile:
Our engineers follow manufacturer guidance and SFG20 where applicable to ensure tasks are risk‑appropriate and traceable.

We align visit tasks with SFG20 maintenance guidance for AHUs and provide the documentation FM teams and auditors expect: attendance logs, checklists, readings, and remedial priorities by risk (H/M/L), and recommendations prioritised by risk and compliance impact.
Beyond core maintenance, we identify opportunities to reduce energy use and improve IAQ, including filter grade optimisation, coil cleaning schedules, fan/motor upgrades, and control strategy tweaks. For clients working toward EPC goals or net‑zero, we can coordinate energy surveys and reporting.
Where issues are found, minor remedials can be completed during the visit with approval. Larger works are quoted with scope and parts. All repairs and installations carry a 6‑month warranty.
We cover London, Essex, and Kent with a rapid response for emergencies and planned visits scheduled to minimise disruption.
Next steps
We’ll survey your plant (number of AHUs, sizes, access, condition) and provide a fixed‑scope contract with clear inclusions, exclusions, and visit frequency.
Contract pricing is based on unit quantity/size, access, runtime/criticality, filter grade, and coil/fan condition. We’ll survey your plant and provide a fixed‑scope proposal with optional add‑ons (deep cleans, coil chemical cleans, filter upgrades).
