What we deliver

HVAC and mechanical engineering maintenance: SFG20-scheduled PPM, not guesswork

HVAC maintenance is the scheduled servicing and reactive repair of heating, ventilation and air conditioning plant, carried out to a defined standard so the equipment remains compliant and runs to its design efficiency and life-cycle expectations. Rossair delivers it as SFG20-scheduled planned preventative maintenance across the full estate, with balanced HVAC and mechanical engineering expertise: heating, ventilation, air conditioning, BMS controls and the wider mechanical plant. Every contract includes 24/7 reactive cover, named engineers and a 24-hour job report. As a one-stop shop for building compliance, Rossair covers the wider statutory estate under the same agreement: fire smoke dampers, fire doors, dry risers and sprinkler systems.

  • SFG20-scheduled PPM across all building services
  • Legionella Risk Assessment (LRA) compliance documentation in every contract
  • F-Gas compliance records and certification
  • One-stop shop for building compliance: fire smoke dampers, fire doors, dry risers and sprinkler systems
  • 24-hour job report after every reactive callout

Long-term named-client relationships are how a HVAC maintenance contract earns the benefit of the doubt at year three. Chichester College Group has been a Rossair-maintained estate for over 20 years across 11 campuses - "a trusted and valued partner across all 11 campuses", in the words of its estate manager. The Quebec Government Office in London is into its second decade of weekly maintenance. Same engineers. Same account manager. Same response number.

Frequently asked

Questions about HVAC maintenance contracts

What is HVAC maintenance?
HVAC maintenance is the scheduled servicing and reactive repair of heating, ventilation and air conditioning plant - chillers, heat pumps, boilers, air handling units, split and VRF air conditioning, and the controls that run them. Planned preventative maintenance (PPM) keeps equipment compliant and running to its design life; reactive cover handles breakdowns when they happen. A commercial HVAC maintenance contract from Rossair combines both, scheduled to SFG20 with LRA and F-Gas compliance built in, named engineers, and a 24-hour job report after every callout.
What does a Rossair PPM contract include?
A Rossair PPM contract includes SFG20-scheduled planned preventative maintenance visits, Legionella Risk Assessment (LRA) compliance documentation, F-Gas compliance records, 24/7 reactive cover, named engineers, and a 24-hour job report after every reactive callout. Scope is tailored to the asset register of each building.
What is the difference between PPM and reactive maintenance?
PPM (Planned Preventative Maintenance) is scheduled maintenance carried out to prevent breakdown. Reactive maintenance is the emergency response when plant fails. Rossair includes both in every maintenance contract - one agreement covers scheduled visits and out-of-hours callouts, billed against an agreed framework rather than per-emergency.
Does Rossair cover air conditioning maintenance and installations?
Yes. Rossair covers all HVAC plant including split and VRF air conditioning, mechanical ventilation, heat pumps, boilers, chillers, and BMS. See the dedicated air conditioning maintenance page for split, VRF and chiller scope.
What areas does Rossair cover for HVAC maintenance?
Rossair operates UK-wide with offices in Alton (Hampshire HQ) and London (Aldgate). Planned maintenance contracts run densely across Berkshire, Surrey, Hampshire, Sussex and inside the M25; multi-site clients are covered nationwide. London-based estates and Hampshire estates have dedicated location pages.
