Coole & FrostCoole & Frost

Design

Slim. Flat. Quiet.

We stopped hiding air conditioning and started designing it: a slimline wall unit flat enough to belong in a period bedroom, and a low floor unit that sits exactly where the radiator used to — each placed with the room, not against it.

Two placements

Up high — or down where the radiator was.

Every room offers a natural home for its unit. We choose with you, room by room, at the design visit — and nothing is chased through original fabric either way.

The high mount — the wall unit

Above the door or opposite the bed, clear of pictures, cornices and sight lines. Cool air washes along the ceiling and settles evenly — no draught on anyone's neck. Aligned to panelling and joinery, so the eye reads architecture, not equipment.

The radiator position — the floor unit

Low against the wall, precisely where the radiator has always lived — the eye reads it as heating, because it is. Our quietest unit at 31 dB(A), barely above a cat's purr, warming at ankle height in January and cooling gently in July.

And if you'd rather it disappeared entirely, we can provide a radiator-style cover — cabinetry that matches the ones your house already has.

The details

A fascia worth looking at.

Flat planes, soft corners, a matt finish and a small Coole & Frost badge — no glossy plastic, no winking lights, no branding shouting from the wall. This is the only part of the system you'll see every day, so it's the part we've obsessed over with our manufacturing partner.

  • Slimline chassis — 201mm deep, barely a hand-span off the wall
  • Matt white as standard; our paint-ready fascia is coming soon
  • Display dims to nothing at night — no glowing numbers over the bed

A first for the market Coming soon

Paint it to your walls.

The number one objection to air conditioning in a period home is simple: you can see it. So we designed the fascia to disappear. The front panel clips off and is supplied in a matte primed finish — made to be sprayed by your own decorator, in your own wall colour.

It's painted off the unit and refitted afterwards, so there's no overspray and no compromise to performance. The grilles, louvres and sensor window stay exactly as engineered — untouched on the chassis. What's left on the wall reads as joinery, not equipment.

As far as we know, no one else offers this — and it answers the one aesthetic objection every period home makes.

Period homes

Victorian outside. Your choice of temperature inside.

Period houses are the point of this company, not the exception to it. Cornicing, picture rails and lath-and-plaster stay exactly as they are: the unit mounts on two brackets, pipework runs in slim colour-matched trunking down the external wall, and nothing is chased through original fabric — ever.

Positions are chosen with the room, not against it — aligned to panelling, clear of cornices and picture rails — and the room keeps every one of its 130-year-old details.

Outside

The outdoor unit, handled with tact.

Every system needs one condenser outside — and only one: a single compact unit serves the whole house, sited on a rear or side wall below sight lines, screened by slatted enclosures or planting. Even the largest in the family is a fifth of the size planning rules allow, and the MCS noise assessment we run for every install is what keeps the whole job inside permitted development.

  • One condenser per house — the planning-friendly, neighbour-friendly way
  • Noise modelled to the MCS 020 method before we install, not after
  • Anti-vibration mounts as standard; cedar-slatted enclosures to order
