Multi-split systems can reduce the number of outdoor units, but layout, simultaneous demand and longer pipe routes require careful design.
What a useful quote should cover
- Capacity available when several rooms call at once
- Pipe length and height limits from the manufacturer
- What happens to all rooms if the outdoor unit is unavailable
- Access to concealed joints and drainage routes
Compare evidence, not badges
Ask each business for the legal name that will contract with you, relevant individual and company credentials, insurance details, equipment schedule, exclusions, warranty route and payment terms. Verify evidence with the issuing body where possible.
