Home check
Domestic enquiries work best when the first message shows how the room connects to the outside wall, where water can drain, and how the outdoor unit could be reached safely.
Typical projects
These examples help customers recognise the kind of enquiry they are making before comparing equipment tiers or assuming a single headline price.

Usually the clearest starting point: one indoor unit, one outdoor unit, and a path that can be checked from photos.

The decision is not just room count. Pipe routes, simultaneous use, outdoor capacity, and service access all need a closer look.

Commercial timing, customer disruption, existing labels, and access risk can affect the work as much as equipment choice.
Pick the closest match for your home
A bedroom, loft room, living room, and garden office can all need different noise, airflow, pipe route, and outdoor-unit assumptions.
Prioritise quiet indoor operation, outdoor-unit noise, low light, and controller access for overnight comfort.
Focus on room size, sun gain, ceiling height, insulation, and how the indoor unit can throw air across the space.
Check power supply, wall construction, distance to the outdoor unit, and whether heating support is also important.
Homes that need cooling, heating support, or both in bedrooms, living spaces, offices, and hard-to-cool rooms.
Unit capacity, indoor and outdoor positions, drainage, pipe route, electrical checks, and access.
Room view, indoor wall, outside wall, outdoor location, pipe route, drainage, and fuse board.

Before you send it
A clear first request helps Trust AC check the site faster and keeps the next step practical.
A single-room installation usually takes a single day in most homes. More rooms, long pipework or electrical work can push it to two days or more, and we tell you which applies before you commit.
There is drilling through an external wall and some dust. We sheet up, tidy as we go, and tell you in advance what will and will not be made good.
It depends on whether the unit heats as well as cools — and whether you will actually use it for heating. A unit used solely for cooling needs planning permission; a reversible heat pump on a house that genuinely provides heating is often permitted development within the limits. Our planning guide sets out where you stand.
