Comfort you notice by not noticing it.

Stillair designs and installs heat-pump systems for homes where quiet, even warmth matters as much as the efficiency figures.

What Stillair designs for

Quiet

Indoor units you do not hear over a conversation, and an outdoor unit placed away from bedroom windows.

Even

The same temperature in the kitchen and the far bedroom, without hot blasts or cold corners.

Considered

Equipment that disappears into the architecture instead of announcing itself on the wall.

The consultation

Four chapters, from first visit to the first quiet winter.

  1. Pale plaster wall with a single dried branch in a vaseI

    A conversation about the house

    How each room is used, where it is too warm or too cold, what the walls and windows are made of. We listen before we measure.

  2. Afternoon light falling across a white wallII

    A room-by-room load study

    Heat loss and gain calculated for every space, so equipment is sized to the house rather than to a rule of thumb.

  3. Minimal black wall control set into walnut panellingIII

    A proposal you can read

    Where each indoor unit goes, where the lines run, what it will sound like, and what it costs. Drawn, not just priced.

  4. Outdoor heat-pump unit beside a white house wallIV

    A careful installation

    Line sets hidden in closets and chases, outdoor units placed for sound and snow, and a walk-through when we leave.

Calm bedroom with timber ceiling and linen bedding

Bedrooms are where a system is judged.

A system can be efficient on paper and still keep someone awake. We specify indoor units by their sound at low speed, set them to run long and gentle, and keep air off the bed.

Begin with a conversation.

A first consultation is an hour at the house. We bring questions, not brochures.
