Businesses & Offices
A broken AC on Monday morning = office at a standstill and lost productivity. Office AC, central VRF/VRV system maintenance and rapid intervention to keep a comfortable workplace all year round. Call us to schedule ahead of peak season.
Businesses, offices and administrations in Morocco — from service-company headquarters in Casablanca and Salé, to law and engineering firms in Marrakech and Tangier, to bank branches and call centres — share one common need: a comfortable working environment that preserves team focus and productivity. A broken AC on Monday morning is not just discomfort; it means delayed meetings, underperforming staff, and clients received in an unacceptable room temperature. Sengo operates from Marrakech and covers 9 regions, providing maintenance and interventions on office systems: multi-zone DRV/VRV, ceiling cassettes, false-ceiling ducted systems, dual-flow ventilation. We coordinate with the facilities or maintenance lead and schedule interventions in the evening or on weekends to avoid disruption. Invoicing is compliant (ICE, RC) and bookable as maintenance expenses, and multi-site contracts are available for companies with multiple branches. The warranty on work is written. The multi-brand approach (Daikin, Mitsubishi, LG, Toshiba, Gree and others) enables servicing a mixed fleet without constraints.
Common issues
- Insufficient cooling in summer
- Recurring breakdowns
- High energy bills
Equipment and systems we service
Multi-zone DRV/VRV systems
Centralised DRV/VRV systems (Daikin, Mitsubishi Electric, LG, Toshiba, Hitachi) feed multiple offices or floors from a single outdoor unit, with independent zone control. Maintenance on the outdoor unit, indoor units, gas sensors and central controller. Diagnostics via available reading tools, and coordination with the energy manager to propose improvements.
Ceiling cassettes
Cassettes integrated into the false ceiling (4-way, 2-way) are the most common in open-space areas and meeting rooms: filter maintenance, condensate pump (a common source of ceiling leaks), heat exchanger and fan motor. Regular cleaning is essential to avoid odours, airflow drops and water leaks.
False-ceiling ducted systems
Units fully concealed in the ceiling, distributing air via a duct network: unit maintenance, exchanger and filter cleaning, duct insulation checks, zone-by-zone diffuser adjustment. Especially important because faults here are hard to diagnose given access difficulty.
Dual-flow ventilation and air handling
Dual-flow ventilation (extraction + filtered supply) in modern buildings, and air handling units (AHU) in larger offices: filter maintenance, recovery-exchanger checks, extraction-duct cleaning, and flow balancing. Important for indoor air quality (IAQ) and team comfort.
Single and multi-split units
Small and mid-sized offices often run on standalone splits (Gree, Midea, Samsung, Carrier, Panasonic) or multi-splits for several offices. Filter, gas charge, drain and outdoor-fan maintenance. Typically fast intervention.
Regulatory context and industry standards
Offices and administrations in Morocco are subject to labour law requiring an acceptable air-quality and temperature work environment, especially in open-space areas. Buildings with environmental labels (LEED, HQE, or internal Moroccan frameworks) require energy and ventilation maintenance documentation. Refrigerant handling (mainly R32, R410A in modern offices) follows international environmental rules applied in Morocco. Invoicing with ICE and RC is necessary for companies to book the intervention as tax-deductible expenses. Listed or audited companies require detailed invoices and written intervention reports for financial and internal audit. This backdrop explains why the facilities manager seeks a provider offering structured documentation.
Typical interventions we see in this sector
Generic examples to show the nature of the work, with no client disclosure.
Entire zone without AC on a hot morning
A facilities manager calls on a Monday morning: an entire floor is without AC while it's over 38°C outside. Priority. The technician checks the outdoor unit (breaker, thermal protection, pressure), central regulation and gas sensors. Common causes: breaker tripped over the weekend, blown fuse, or a regulation defect. Interim solution to restart some units while a rare part is ordered.
Water leak from a false ceiling
Reception sees water dripping from the ceiling near a cassette. Unit shut down immediately. The technician checks the condensate pump (most common cause, clogged), drain-pipe condition, and unit insulation. Full pump and pipe cleaning, drainage test, and repair of any damaged pipe. Written report with recommendation to schedule periodic pump cleaning.
Temperature imbalance between neighbouring offices
Teams complain one office is too cold, another too hot. The technician measures flows, checks the distribution network and diffusers, readjusts thermostats and zoning, and proposes diffuser repositioning if needed. Fix can be simple (rebalancing) or require a distribution change.
Weekend scheduled maintenance visit
The company books a Saturday visit to avoid disrupting teams. Sengo executes: filter cleaning, condensate-pump checks, outdoor-unit cleaning, gas checks, unit testing, thermostat adjustment. Detailed per-unit consolidated report with performance and consumption improvement suggestions. Monday morning, everything is running at its best.
Seasonality and year-round needs
Offices in Morocco peak in June–September (heatwaves especially in inland cities — Marrakech, Fès, Casablanca) when AC runs at maximum at least 8 hours a day. Winter in the North and Atlas (Tangier, Ifrane, Sefrou) drives AC in reverse-cycle heating mode. Preventive maintenance is ideally planned in April–May (before peak heat) and October (before heating season if applicable). Failures cluster on Monday morning after the weekend, and during the first heatwave when units are called on after months of idleness. Planning maintenance before these peaks materially reduces emergencies.
Why a contract beats one-off call-outs
Offices without a contract run reactively: wait for the failure, then call an emergency. With a contract, maintenance is planned, the budget is controlled, and interventions happen in the evening or on weekends without disturbing teams. Preventive visits catch clogged condensate pumps before a ceiling leak and spot low gas charge before performance drops. Regular invoices and written reports serve the finance team and book as deductible maintenance expenses. For multi-branch companies, a unified multi-site contract simplifies management. Sengo offers three contract tiers covering everything from a medium office to a multi-floor headquarters — the choice depends on fleet size, number of sites, and required responsiveness.
