PLANNING / SELECTION / HANDOVER
Before choosing the equipment
Ask the designer to explain expected comfort during the least favourable local weather, not only a dry-day example. Discuss water supply, discharge, outdoor air and seasonal servicing.
What belongs in the quote
Have the proposal define the operating conditions and maintenance responsibilities. Compare the scope with refrigerant-based cooling where humidity control is part of the brief.
Think about the surrounding system
Cooling selection begins with the rooms, glazing, occupancy and humidity conditions. Request a load assessment and ask how airflow, drainage and noise will be addressed. The installation scope should identify the indoor and outdoor equipment together, including any changes to electrical service or distribution.
Three questions for your contractor
- Is the local climate suitable?
- How will water use and discharge be handled?
- What performance should be expected on humid days?
Prepare a useful first conversation
Bring the site location, building use, equipment model details and photographs of accessible equipment. Describe the problem or planned change and any access or shutdown constraints. Ask the contractor to identify design assumptions, excluded work, required approvals and who will commission the finished system.
This is a project-planning guide. Final equipment selection and installation details need a qualified contractor or designer familiar with the site.
