How It Works

Air conditioning, made simple.

An air-to-air heat pump moves heat rather than creating it. That's the whole idea, and it's why the same system heats your home in winter and cools it in summer.

The Mechanism

It moves heat. It doesn't make it.

Your air conditioning system uses refrigerant to move heat from one place to another.

Summer

Take heat out of your home

When your home gets hot, the system reverses the cycle. The indoor unit takes heat from your rooms and transfers it outside, leaving your home cooler.

Winter

Bring heat into your home

Even when it's 0°C outside, there is still usable heat in the air. The outdoor unit captures that heat, the system concentrates it and transfers it indoors.

Why it is so efficient

The system moves heat rather than creating it. That's why one unit of electricity can deliver around 3–4 units of heating or cooling, while a standard electric heater produces around one.

  • Heating & cooling from the same equipment
  • No flue, no gas, no combustion in the property
  • Air filtration as air passes through the indoor unit
  • Room-by-room control so you only heat or cool the spaces you're using

The Kit

What's actually in your home.

An air conditioning system is made up of a few simple components, all designed to work together. The installation is neat, discreet and planned around your home.

Outdoor unit

The unit that does the heavy lifting

The outdoor unit sits outside your property and contains the compressor and other components that move heat in or out of your home.

Indoor units

One for each room you want to control

Slim indoor units sit high on the wall and quietly distribute warm or cool air into each room.

Pipework

The connection between the two

Small refrigerant pipes and cables connect the indoor units to the outdoor unit. We run these through discreet trunking wherever needed to keep everything neat.

Install Day

What happens on installation day?

Most installations are completed in a single day. Our engineers take care of everything from fitting the units and connecting the pipework to testing the system and setting up your controls.
  1. We prepare your home

    Your engineer arrives, confirms the agreed plan and protects your floors, furniture and work areas before getting started.

  2. We install your system

    Indoor units go up, pipework is connected and the outdoor unit is securely mounted with room for airflow.

  3. We test, tidy and set you up

    We test and commission the system, complete the required paperwork, set up your Brisk app and leave everything ready to use.

Placement

Where the outdoor unit goes.

Four positions cover almost every home we work in. The right one depends on airflow, how sound carries and what your freeholder will sign off — we confirm it at the survey.

Garden, on feet

Anti-vibration feet, clear airflow, short run to the wall.

Wall brackets

Galvanised brackets, isolation pads so nothing carries indoors.

Noise

Noise, properly explained.

Two figures matter. The indoor unit on low is around 19 dB, quieter than a library. The outdoor unit at three metres is around 40 dB, about the level of a quiet conversation. Where the outdoor unit would sit close to a neighbour's window we say so before you commit, and suggest another position if one exists.
