Every year, facility managers across Dubai sign an AC AMC — an annual maintenance contract — and only discover what it actually covers when a chiller trips in August and the invoice arrives. The contract said “maintenance included.” It did not say which maintenance, how often, with what response time, or who pays for parts.

This guide fixes that. Here is exactly what a proper commercial AC AMC in Dubai should include, what it usually leaves out, and the clauses to demand in writing before you sign — written for offices, hotels, retail, restaurants, warehouses and towers, not villas.

What Is an AC AMC?

An AC annual maintenance contract is a 12-month agreement where one contractor takes responsibility for your cooling systems: scheduled preventive maintenance (PPM), inspections, performance checks and priority breakdown support, for a fixed annual fee. Instead of calling a different company for every fault, you have one accountable provider, one service calendar and one number to call.

For a commercial building, the AMC is not a cleaning subscription. Done properly, it is an uptime agreement — and it should read like one.

What a Good Commercial AC AMC Includes

1. Scheduled PPM visits with a written task list

Quarterly visits minimum for commercial systems; monthly for hotels, towers and chiller/VRF plants. Each visit should follow a written checklist: filter cleaning or replacement, evaporator and condenser coil inspection, drain line flushing, refrigerant pressure checks, electrical connections and capacitor testing, thermostat calibration and cooling performance verification. If the contract just says “general servicing,” you are buying a filter wipe.

2. System-specific scope: chillers, VRF, AHUs and FCUs

Your contract should name your actual plant — chillers, cooling towers, VRF/VRV systems, air handling units, fan coil units, pumps and packaged units — with the maintenance each one gets. Chiller and VRF work requires manufacturer-trained technicians; a general handyman clause is a red flag.

3. Priority breakdown response with a real SLA

The single most valuable clause. A commercial AMC should commit to a response time in writing — for example, emergency attendance within 2–4 hours, 24/7 — and state how many callouts are included. After-hours premiums in Dubai commonly run AED 100–300 per call when they are not covered, so “priority response” without numbers is marketing, not a service level.

4. Service reports and an asset register

Every visit should end with a written report: what was checked, readings taken, faults found, work recommended. Over the year this builds an asset register for your plant — condition, age, repair history — which is what your insurer, your landlord and your own budget planning actually need.

5. Discounted (not “free”) repair rates

Honest contracts give AMC clients a defined discount on labour and parts — 10–20% off parts is the common market offer — or include minor parts up to a stated limit. Ask for the parts price list, not just a percentage.

6. One annual deep-clean provision

Mid and upper-tier commercial contracts typically include one chemical coil clean per year. Confirm it in writing; bought separately, chemical coil cleaning runs roughly AED 200–600 per unit.

What an AC AMC Usually Does NOT Include

• Major spare parts. Compressors, fan motors, PCB boards and pumps are almost never covered — you get a discount, not a replacement. Repeated refrigerant top-ups are also excluded: a system that keeps losing gas has a leak, and leak repair is a separate, quoted job (ad-hoc recharges alone run AED 200–400).
• Duct cleaning. Almost never included. Budget it separately — commonly AED 800–2,500+ depending on property size — every 2–3 years.
• Unlimited callouts. Better contracts cap included emergency callouts and charge beyond the cap. Know your cap before summer.
• Damage from misuse or third parties. Standard exclusion, along with relocation and modification work.

None of these exclusions are unreasonable. What is unreasonable is discovering them mid-breakdown. A good contractor states them upfront — which is why our AC maintenance cost guide shows the market ranges before you ever ask for a quote.

10 Questions to Ask Before You Sign an AC AMC in Dubai

1. How many PPM visits per year, and what is the written task list for each?
2. Does the scope name my systems — chiller, VRF, AHU, FCU — individually?
3. What is the emergency response time, in writing, and is it 24/7?
4. How many breakdown callouts are included, and what does an extra one cost?
5. Are after-hours and weekend premiums charged? How much?
6. Is a chemical coil clean included? How many units?
7. What discount applies to parts, and can I see the parts price list?
8. Do I get a written report and updated asset register after every visit?
9. Who are the technicians for chiller/VRF work — certified specialists or general staff?
10. What are the exit terms if service levels are missed?

If a contractor answers all ten clearly, you have a real AMC. If the answers are vague, you have a cleaning subscription at an uptime price.

FAQs: AC AMC Dubai

How long does an AC AMC run?

12 months is standard, renewable annually. Multi-year terms sometimes earn a discount, but a one-year start lets you judge performance through a full summer first.

How many visits should a commercial AMC include?

Quarterly as a minimum. Hotels, towers and buildings with chillers or VRF systems should be on monthly PPM — continuous operation in Dubai’s heat and dust wears plant too fast for quarterly checks alone.

Is an AMC worth it for a small office?

Yes, if cooling downtime costs you business. A small office AMC (typically AED 2,000–4,000/year) buys scheduled servicing plus priority breakdown response — the two things pay-per-visit cannot guarantee in peak season.

What’s the difference between a basic and comprehensive AMC?

Basic covers scheduled servicing and inspections. Comprehensive adds callout allowances, parts discounts or minor-parts cover, deep cleaning and stricter SLAs. Compare scope line by line, not headline price.

Can one AMC cover AC plus plumbing and electrical?

Yes — bundled building maintenance contracts exist and usually cost 15–25% less than separate agreements, because one team is already on site. For commercial buildings, a single accountable contractor for MEP is usually the cleaner arrangement.
