Home air conditioning decisions start with the room, the fabric of the building and how occupants use it. A credible quote should follow a survey, not a guess based only on floor area.
What this service usually involves
- Room-by-room heat gain and likely occupancy
- Indoor and outdoor unit position, pipe routes and condensate drainage
- Noise at your property and nearby homes
- Electrical supply, controls and ongoing maintenance
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.
