A good annual maintenance contract (AMC) in Riyadh covers scheduled preventive maintenance of HVAC, electrical, plumbing and fire-safety systems plus call-outs, with the visit schedule, response times and exclusions written down. Compare quotes on scope and response, not price alone.
In Riyadh, an air-conditioning failure in July is not an inconvenience; it closes an office or empties a home. An annual maintenance contract spreads the cost of keeping systems healthy across the year and gives you someone to call when something breaks. But AMC quotes vary widely, and the cheapest often covers the least.
What an AMC should cover
- HVAC: filter and coil cleaning, drain lines, refrigerant checks, thermostats, and a full service before summer
- Electrical: distribution boards, connections, lighting, sockets and emergency lighting
- Plumbing: pumps, tanks, water heaters, leaks and drainage
- Fire safety: alarm and detector tests, extinguisher checks and records for Civil Defense
- Optional: CCTV and access control, and interior upkeep such as ceilings, doors and paint touch-ups

Five things to check in any quote
- Visit schedule: how often each system is serviced; quarterly for HVAC and fire safety is common, plus a pre-summer AC service
- Response time: how fast they respond to an emergency call, and whether that is written into the contract
- What is excluded: spare parts, refrigerant top-ups, major repairs and after-hours visits are often extra
- Who does the work: an in-house team or subcontractors
- Reporting: a written record of each visit and the condition of each system
Offices vs villas
Office AMCs focus on keeping the business running: visits outside working hours, a log for facilities teams, and quick response for HVAC and power. Villa AMCs focus on the systems families depend on: AC before summer, water tanks and pumps, heaters, and waterproofing after rain. See our checklist for preparing a villa for summer.

What affects the price
Property size, the number and type of systems, visit frequency, required response times, and whether parts are included. Ask every provider to quote the same scope so you can compare like for like.
When to sign
Ideally at handover of a new fit-out, so the maintenance team knows the systems from day one, or in early spring, so the pre-summer AC service is done before the heat arrives. Nikken Moller offers annual maintenance contracts in Riyadh for offices, villas and commercial buildings, with our own in-house MEP team.
Scheduled preventive maintenance of HVAC, electrical, plumbing and fire-safety systems plus call-outs, under one yearly contract.
Commonly quarterly, with a full service before summer, because units run hard for much of the year.
It depends on the contract. Many AMCs exclude parts and major repairs, so check the exclusions before comparing prices.
