The number of indoor units is a useful starting point. The rooms, equipment and work needed to fit them determine the quote. These examples show what to compare for a home or small business in London or Essex.
Request an installation quote ↗These are planning examples, not descriptions of completed jobs or fixed-price packages. A written quote needs to reflect your property and the agreed work.
A single-split system has one indoor unit connected to one outdoor unit. The quote needs to identify both positions, the equipment model and the route between them.
An upstairs room, an internal wall or a difficult drainage route can involve different work from a ground-floor room with an accessible outside wall.
Bedroom placement and noise →List each room separately. A suitable multi-split connects several indoor units to one outdoor unit; separate single-split systems are another arrangement to compare.
Each indoor unit still needs its own installation work. Equipment compatibility, pipe routes and the rooms used at the same time affect the proposal. Two units do not automatically mean twice the price.
Compare system arrangements →Start with a room list and a simple floor plan. The number of outdoor units depends on the equipment, capacity and layout; it cannot be decided from the indoor-unit count alone.
Routes between floors, access to each room and electrical provision need assessing together. If work might happen in stages, raise that before the equipment is selected.
Planning for business premises →Tell us how many rooms you want to cool or heat and which need separate control. One unit in a hallway should not be assumed to condition every closed bedroom. A large open-plan room also needs assessment rather than choosing equipment by room count alone.
On the enquiry form, select 1–7 indoor units or Not sure. Count indoor units, not the outdoor equipment. For servicing, give the number of indoor units needing attention. This is an estimate for the enquiry, not a final system design.
Send your unit count with an enquiry →Exact indoor and outdoor models, quantities and capacities, plus any optional controls. State whether each room needs cooling, heating or both.
The route, insulation and visible trunking. Confirm whether wall chasing, decoration and making good are included or need arranging separately.
How condensate will leave each indoor unit, including any proposed pump and its maintenance access. A convenient indoor wall does not always have a simple drain route.
The required supply and isolation, who will carry out that work and whether it is included. Existing electrical provision needs checking for the proposed equipment.
Floor level, outside access, parking and any access equipment. If replacing a system, confirm removal and disposal of the existing equipment.
Operational checks, documents and controls guidance, along with the equipment warranty terms and any servicing requirements.
Compare written quotations against the same scope, including exclusions, payment arrangements and proposed scheduling. Avana Air Ltd is not VAT registered.
Photos help with an initial discussion. A survey may be needed before equipment, installation arrangements and a price can be confirmed.
The installation price covers the agreed equipment and work. Later electricity use depends on the model, room, weather, settings, operating hours and tariff. Servicing is another ongoing consideration. An installation quote alone cannot establish annual running costs.
