Procurement guides
Single-split or multi-split: prepare procurement correctly
Single-split connects one indoor and one outdoor unit. Multi-split connects several compatible indoor units to one outdoor unit. The right solution depends on the building and sizing; for procurement, the main differences are the equipment list and combination checks.
Single-split: one clear equipment combination
Each combination is checked as a pair of indoor and outdoor units. Several independent systems require several outdoor units. Mounting areas, pipe routes and local requirements remain part of professional planning.
Multi-split: consider multiple rooms together
Indoor units must match the connection options and approved combinations of the outdoor unit. Not every numerical sum of individual capacities is permitted. Request the combination table for the exact version.
Replacement procurement is more than a capacity comparison
A new unit with the same kW rating is not automatically compatible. Series, model generation and the manufacturer-approved combination are among the decisive factors. Document all existing components when replacing equipment.
What the quote should include in both cases
Complete models, quantities, installation accessories, required documents and delivery terms create a common basis for comparison. Installation and commissioning must be clarified separately. KLIMAFAKTUR accepts these details in the B2B enquiry.

Frequently asked questions
- Is multi-split always more economical?
- This cannot be answered generally without comparing projects. Equipment, installation, use and operating requirements must be considered together.
- Is floor area enough to select equipment?
- No. Use, solar gains, the building and internal loads all affect demand. The contractor should determine the required capacity.
