Installation · ONEHUB AIR CONDITIONING
What affects air conditioning installation cost?
An installed price depends on the matched indoor and outdoor equipment, room requirements, complete pipe route, drainage and access. OneHub’s estimator prices eligible single wall-mounted systems from your answers; specialist installations receive a bespoke quotation.
Why is a unit-only price different from an installed price?
An equipment listing may cover only the indoor unit, the outdoor unit or a matched pair. Installation also requires appropriate pipework, insulation, cable, drainage, supports, consumables, labour, testing and commissioning. Compare the exact model pair and scope, not just the headline number.
Budget, Standard and Premium describe equipment choices rather than a different standard of workmanship. Capacity, control features, appearance and available ranges affect the options. Our estimator only shows combinations currently priced for the recommended capacity; not every tier or brand exists at every size.
What does OneHub’s online installation estimate include?
For an eligible installation, the estimate accounts for the selected complete system, normal installation labour, testing and commissioning, pipework and related materials for the selected route, appropriate supports, condensate drainage and an AC isolator. Internal-wall estimates include a pump under the current installation assumptions.
The estimate covers AC work and connection to a suitable supply. A new electrical supply or circuit and consumer-unit work are excluded and must be checked and priced separately where needed. Final equipment availability, route, drainage, access and scope require confirmation before installation.
Which details most affect the price?
| Detail | Why it matters |
|---|---|
| Capacity and equipment range | The room load and chosen product determine the appropriate matched system. |
| Total pipework route | Measure the whole indoor-to-outdoor route, including horizontal and vertical sections. |
| Indoor and outdoor positions | Drainage, supports and safe access affect materials and working time. |
| Electrical supply | Any new circuit or associated electrical work needs a separate scope. |
| Specialist installation | Ducted, concealed, cassette, multi-split and larger systems need design and assessment. |
When is a site survey needed?
The online journey is intended for one straightforward wall-mounted split. Multiple systems, high-level or roof positions, unusual access and other details outside that scope need a survey or bespoke assessment. A normal first-floor external-wall installation can remain eligible when the full route is included and the outdoor position and access are suitable.
An online estimate is an initial guide, not a confirmed booking or final quotation. Use it to explore available systems, then ask OneHub to confirm the requirements. We avoid a single generic starting price that may not describe your room or installation.
Common questions
Can I get Budget, Standard and Premium prices at the end?
You can compare the priced options available for your recommended capacity and installation answers. Some capacities do not currently have every tier.
Does the online price book the installation?
No. OneHub confirms the final equipment, site requirements and quotation before work is arranged.
