Air conditioning
Cool in summer, efficient heat the rest of the year — from the same units.
Modern air conditioning does both jobs. It cools the house through the warm months, and the same units run in reverse to heat rooms efficiently when it's cold. And in summer, when your solar is producing most, it can run on power you're already making.

What it actually does
One system, two jobs — cooling and heating
An air conditioning unit moves heat rather than making it. In summer it takes warmth out of the room and pushes it outside, so the house stays comfortable through a hot spell. In winter the same unit works the other way round — pulling warmth from the outside air and bringing it in.
Because it moves heat instead of burning fuel to create it, running it for heating can be more efficient than a plug-in heater or, in some homes, electric heating. It won't suit every room or replace every system — but where it fits, it earns its keep across the whole year, not just July.
Not the noisy boxes you remember
Quiet, efficient, and controlled room by room
Today's inverter-driven units are a world away from the loud, thirsty systems of a decade ago. They ramp gently to hold a set temperature instead of roaring on and off — which is exactly what makes them both quiet and efficient.
Room-by-room control
Cool or heat only the rooms you're using, each at the temperature it wants — no conditioning the whole house for one room.
Quiet, inverter-driven
The compressor modulates rather than blasting on and off, so it holds a steady temperature with very little noise, indoors or out.
Cleaner air, too
The indoor units filter the air as they run, which helps with dust and pollen through the year — a small bonus on top of the comfort.
What's included
A complete Daikin system — inside and out
Every install is a matched Daikin pair: a wall unit inside for the room, and a quiet outdoor unit that does the work. Genuine Daikin equipment, fitted by F-Gas certified engineers.
Indoor unit
The Daikin Stylish wall unit — sleek, and barely there in the room.
Outdoor unit
Sits outside and does the heating and cooling — efficient R-32, and quiet in operation.

Why it pairs with solar
You need it most when your panels make the most
The hottest days — when you'd run the cooling — are also the days your panels produce the most. That overlap is what makes air conditioning and solar sit together well.
Cooling on your own power
Bright summer days give you the most generation. Run the cooling then and much of it can come straight from the roof.
Uses power you'd otherwise export
Spare midday generation that would go back to the grid cheaply can cool the house instead — more of what you make, used at home.
Sized from real usage
We look at your half-hourly data and the rooms you'd actually use it in, so the system matches the home — not a rule of thumb.
The honest bit
Straight about summer, and about the rest of the year
In a British summer you won't run the cooling every day — some years you'll want it more than others. We won't build the case on a heatwave that might not come. What makes air conditioning worth it for many homes is that it isn't only for summer: the same units give you efficient heating through the colder months too.
In winter your panels make far less, so the heating side mostly runs on grid power. We'll set that out plainly in your figures — what the cooling could draw from solar in summer, and what the heating is likely to cost across the year — so you're deciding on the whole picture, not the sunny half of it.
If a unit only makes sense on the assumption of a long, hot summer, that's worth questioning. We'd rather it stack up on the year as a whole.
How we do it
Done properly, and itemised in full
You see exactly what you're paying for — the units, the fitting and the electrical work, not a single vague price.
- A free analysis of your real data before anything is quoted
- A survey with a specialist to work out the right rooms and unit sizes
- Quality units specified to suit the home, for cooling and efficient heating
- A fixed, itemised quote that doesn't move once issued
- Tidy installation and safe electrical work, done to the standard we'd want at home
- Monitoring where it helps, plus an annual review so it keeps performing
Common questions
The things people ask us about air conditioning
Do I need planning permission?
For most homes a domestic unit is permitted development, but there are conditions — the size, where the outdoor unit goes, and whether you're in a conservation area or a flat. We check it for your property and tell you before anything is ordered.
Is it noisy?
Modern inverter units are quiet — the indoor unit is a soft hum, and we site the outdoor unit sensibly so it isn't under a bedroom window or over a boundary. We talk through exactly where it goes at the survey.
How much maintenance does it need?
Very little day to day — a simple filter clean now and then, plus an occasional professional service to keep it efficient and under warranty. We set that out up front so there are no surprises.
Which rooms should I do?
Usually the rooms you live in most — a living space, a home office, a bedroom that gets hot. We size it room by room from how you actually use the house, not a rule of thumb.
Can I run it off my solar?
In summer a good amount of the cooling can come straight off the roof, since the hottest days are also your best generation days. In winter the heating side mostly runs on grid power — we show you both sides honestly in your figures.

Why we start with your half-hourly data, not your annual bill
Your annual kWh hides the one thing that decides what system you actually need: the shape of how you use power.
