Planned maintenance keeps a calibrated building calibrated.
An HVAC installation drifts from the day it is handed over. Filters load, refrigerant charge falls, hydronic water chemistry shifts and control setpoints are overridden. Our maintenance programme measures that drift on a fixed cycle and corrects it before it becomes noise, humidity, energy cost or a breakdown.
Filtration Renewal
Filter banks replaced to grade, differential pressures logged, coils and drain pans cleaned.
Refrigerant Integrity
Leak testing, charge verification and F Gas record keeping against each asset.
Hydronic Water Care
Inhibitor and dosing analysis, strainer cleaning, dirt and air separation checks.
Electrical and Mechanical
Contactor, bearing, belt and vibration checks with thermographic inspection.
Controls Recalibration
Sensor verification, setpoint audit and removal of accumulated manual overrides.
Acoustic Verification
Sound levels re measured at occupied positions against handover benchmarks.
Air Quality Audit
Particulate, carbon dioxide and humidity readings against the design envelope.
Asset Reporting
Photographic condition report, remedial register and energy trend commentary.
Seasonal
Two attendances per year, timed to precede the cooling and heating seasons.
- Two planned visits
- Filtration and coil service
- Annual condition report
- Next business day response
Quarterly
Four attendances per year for occupied estates and mixed use buildings.
- Four planned visits
- Controls recalibration
- Water and refrigerant analysis
- Same day response
- Consumables included
Continuous
Monthly attendance with remote telemetry for critical and prestige assets.
- Monthly planned visits
- Remote monitoring and alarms
- Four hour response
- Named engineer and deputy
- Parts held in stock
Faults are attended by the engineer who commissioned the system
Every asset we maintain carries a telemetry record: run hours, pressure differentials, refrigerant history and control revisions. When a call is raised, the attending engineer arrives with that history and with the correct parts already on the vehicle. Critical commercial plant is covered on a four hour response, estate systems same day.
