Cadnam air conditioning
We cover Cadnam for air conditioning installation. Diagnosis first, a fixed price and proper paperwork when we finish.
- A loft conversion that’s too warm to use
- A system on old refrigerant that’s due for replacement
- Too many options and no clear advice
What we do, step by step
You don’t need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we have done. Rural lanes and tight entrances are worth mentioning before a visit to Cadnam.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Before we arrive
- Mention any roof access, ladders or high-level work
- Clear a path to the units and the space around them
- Keep pets and children away from the work area

Advice
About our air conditioning in Cadnam
Think of it as diagnose, treat and sign off: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. Every installation in Cadnam begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
In a village like Cadnam, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules do not apply to it.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Questions from Cadnam
Will air conditioning in Cadnam need planning permission?
The answer turns on the property and where the outdoor unit would sit. The Forest Central North Conservation Area is close to the centre of Cadnam. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Cadnam, typically New Forest council).
Is Cadnam within the area you cover?
Yes. Cadnam is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Does air conditioning need its own electrical supply?
Most systems need their own supply from the consumer unit. Under Part P, a new circuit has to be notified unless a registered competent person does it, and as NICEIC approved contractors we install and certify it as part of the job.
Can I use air conditioning to heat a room?
Most of the time, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Can you come out in an emergency?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Air conditioning around Cadnam
About 90% of households live in detached or semi-detached houses, according to the last census (2021). A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
With historic houses such as Landford Manor about 4.6 miles north-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules. Homes near Church of St Mary are a good example of where we look up the heritage status of the building before fixing anything to it.

Looking after it afterwards
So the system stays in good health:
- Keep the F-Gas records, commissioning details and warranty information together
- Keep the outdoor unit clear of leaves, plants and clutter
- Wash or vacuum the filters as the manual describes
The work area is left tidy: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Outside, the pipework is neatly fixed and protected, so the job looks as tidy as it works.
Give the outdoor unit room to breathe. Anything piled against it, from leaves to garden furniture, reduces the airflow, and the system has to work harder as a result.
Managing agents and facilities teams in Cadnam
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
For anyone managing more than one building, we can quote and plan the work across all of them. Every address has its own paperwork, so the files stay tidy.
What air conditioning won’t do
Air conditioning can’t fix everything, and we’d rather say so up front. It won’t put right:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Building damp that has a structural cause
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
If you’re not sure, just ring us on 07833 053749 or email us and we’ll give you a straight answer.

What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
