For a useful commercial aircond quotation, send the premises location, service required, unit list, symptoms and access arrangements. A routine servicing quote, fault-repair quote, installation proposal and VRV maintenance scope describe different work. Make the scope clear before comparing prices.
This checklist is for offices, clinics, shop lots, restaurants, factories and mall or retail tenants in Semenyih, Kajang, Bangi, Nilai and Nilai 3. For factory enquiries, identify whether the systems serve offices, staff areas or a production process; the requirements can differ.
1. Say which work you need
- Servicing: routine cleaning, drainage and agreed checks, or a deeper clean where the condition warrants it.
- Repair: troubleshooting for poor cooling, water leaks, error codes, noise or repeated breakdowns.
- Installation: new units, replacement or relocation, including any changes to piping, drainage and electrical supply.
- VRV: system-level maintenance, troubleshooting, repairs or installation assessment.
You can request more than one scope in the same enquiry. See our commercial aircond service, repair, installation and VRV contractor page.
2. Prepare a simple equipment list
Record each unit’s location, type, brand, model and HP or rated capacity. Note whether it is wall-mounted, cassette, ducted or part of a VRV/VRF system. Photos of the unit and accessible nameplate help when labels are unclear.
For VRV/VRF, include outdoor-system model details, indoor-unit quantities, controller type and any displayed error code. VRV is Daikin’s system name; other manufacturers commonly use VRF terminology. Do not assume every indoor unit operates as an independent split system.
For a Daikin system, see our VRV contractor page. Cooling Pros Engineering is a Daikin Authorised Contractor; the actual job scope still needs assessment.
3. Describe the problem and operating pattern
Which rooms are affected? Is cooling weak throughout the premises or only in one zone? When did it start, and does it happen all day or at particular times? Share error codes and previous service or repair records if available.
Include operating hours, occupancy and any area that cannot be interrupted. An office used during business hours and a restaurant running late into the evening may need different maintenance arrangements. A suitable schedule depends on use, environment, equipment condition and manufacturer guidance.
4. Explain access and building rules
- Ceiling height and access panels.
- Outdoor-unit position, roof access and loading arrangements.
- Building-management approval, permits or work-hour restrictions.
- Protection and cleaning arrangements for occupied or sensitive rooms.
- Shutdown windows and whether work needs coordinating with other contractors.
Clinics should explain room-use restrictions and the site’s hygiene procedures. Mall tenants should share the management requirements and whether the equipment belongs to the tenant or building. Share these constraints early so the quotation can address them.
5. Compare the scope line by line
Ask how many units and visits are covered, what cleaning and checks are included, what records will be provided and which items are excluded. Clarify diagnosis charges, parts, refrigerant work, access equipment, electrical work and any applicable taxes.
For repairs, confirm the diagnosis, approval process, parts availability and warranty on the agreed work. For installation, confirm supply, capacity assessment, piping, drainage, controls, commissioning and handover. For maintenance, ask how additional repairs are quoted rather than assuming they are included.
Our installation quote guide explains common scope questions. Our preventive maintenance article covers why planned upkeep matters.
Send your commercial enquiry
A unit list, equipment photos and preferred access time are a useful starting point. Complex systems or uncertain conditions may need a site assessment before we can confirm the proposal and appointment.
