Preventive maintenance
Scheduled maintenance contracts to avoid unexpected breakdowns and keep operations running.
Preventive maintenance is the opposite of repair: instead of waiting for a breakdown and paying the price (spoiled stock, business downtime, lost customers), we intervene on schedule before it happens. A Sengo annual contract covers: visits planned around your operation, a full check of every unit, condenser cleaning and filter changes, gas and defrost-cycle checks, electrical safety tests, sanitation of food-contact equipment (catering, hospitality), a written report after every visit and priority on emergency call-outs. Result: around 70% fewer breakdowns, 20-30% off the electricity bill and equipment life extended by years. Our goal: eliminate surprises — you always know exactly where your fleet stands.

Why it matters
Equipment and systems we service
We work on every format commonly installed in Morocco.
- Restaurant and hotel contract
Quarterly visits (4/year) for a daily-running kitchen: displays, cabinets, prep tables, cold rooms, ice makers and AC. With 7-day emergency priority because every hour of downtime is a loss.
- Office and retail contract
Two visits a year (before summer, before winter): suspended-ceiling AC (cassette, ducted), fan coils and controls. Suited to Monday-to-Friday offices without night activity.
- Industrial contract
Custom frequency by criticality: weekly on critical systems (24/7 negative refrigeration), monthly on the rest. Pharma, dairy and food-processing demand stricter, traceable programmes.
- Clinic and pharmacy contract
Medical and pharmaceutical refrigeration demand precision: visits every 2 months, sensor calibration, HEPA filters for clinics and temperature loggers to ensure cold-chain traceability.
- Villa and luxury residence contract
Twice yearly on residential Multi-Split or VRV: filter cleaning, gas check, sanitation and performance test. Ideal for riads and seasonally-rented residences.
- Custom contract
Specific needs (multi-site, non-standard frequency, unusual equipment)? Custom contract after a preliminary audit. Transparent pricing based on the equipment inventory and number of visits.
Our intervention process
A simple, transparent flow — from first message to a fully working unit.
- 1Free initial audit
First visit to inventory equipment (ACs, displays, cold rooms…), assess overall condition and hear the breakdown history. From this we propose visit frequency and monthly budget.
- 2Contract signature and scheduling
Written annual contract, transparent, no hidden clauses: number of visits, operations covered, emergency response times and included parts. Annual schedule proposed around your operation.
- 3Scheduled maintenance visits
The technician arrives on the agreed dates (3-day reminder sent), works through the checklist, replaces what needs replacing (filters, seals…), and flags any anomaly that could precede a future failure.
- 4Written report after every visit
After every visit you receive a detailed technical sheet: operations performed, measurements (temperatures, pressures, currents), parts replaced, parts to watch and the next visit date.
- 5Priority emergency response
Between scheduled visits, if something breaks unexpectedly, you call us and jump ahead of regular bookings. Response times are contract-guaranteed (depending on the tier chosen).
- 6Annual report and optimisation
At year-end, a full annual review: number of visits, faults handled, parts replaced, electricity-consumption trend and recommendations for the next year (upgrades, frequency adjustment, added equipment).
