The price depends on the number of rooms, required capacity, equipment brand, indoor and outdoor unit positions, pipe length, condensate drainage, electrical supply and how difficult the installation route is. A single straightforward bedroom system will normally be simpler than a multi-room installation with long concealed pipe runs.
Outdoor-unit access can also affect the job. A unit mounted at an awkward height or in a restricted rear court may need additional equipment or labour. Decorative trunking versus concealed routes can change both cost and disruption.
Doherty's Glasgow air-conditioning service is survey-led because the room size and physical installation route need to be assessed together. The useful quotation is the complete installed system, not just the online price of the indoor and outdoor units.
