AC fitting and air conditioning installation describe the complete job, from surveying and sizing through to fitting the units, pipework, drainage and electrical supply. The quote should state exactly what is included.
What this service usually involves
- Room-by-room sizing and equipment selection
- Indoor and outdoor unit positions
- Pipework, condensate drainage and electrical work
- Commissioning, handover, warranty and making good
What a useful quote should cover
Ask for the same scope from every company: rooms or zones, outdoor position options, pipe and drain routes, electrics, access, working hours, VAT, exclusions and warranty route. A low headline total with vague allowances is harder to compare than a complete written proposal.
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. Read what we check and what you should verify.
