Air conditioning for homes and businesses in Horndean
Thinking about air conditioning but not sure where to start? Send a few photos of the rooms and the outside walls when you call us on 07833 053749 or email us, and you will hear back from us the same working day to arrange a survey or a quote. If you want air conditioning in Horndean, you get one team and one number from survey to sign-off.
Around Horndean, older homes and newer ones sit side by side, and the walls decide a lot about the install. Older solid walls need more drilling than modern cavity walls, and a loft or a void can hide a pipe run that would otherwise be on show.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Common questions in Horndean
Do you cover Horndean for air conditioning?
We do: Horndean falls inside our working area. To start, phone us on 07833 053749 or fill in the contact form with a few pictures.
Can I get a fixed-price quote for air conditioning in Horndean?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
Are you F-Gas certified?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.

Homes in Horndean and air conditioning
At about 57 miles from central London, Horndean sits inside the area we cover across London and the South East. The last census (2021) found about 78% of households in detached or semi-detached houses. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
With historic houses such as Warblington Castle about 4.8 miles south-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
Horndean is about 7 miles north-east of Portsmouth, in Hampshire. Whatever kind of property you have in Horndean, we can help with air conditioning.

Different systems, different jobs
Multi-split systems
With a multi-split, one outdoor unit serves two or more rooms. It’s a neat answer when space outside is limited and several rooms need it and each indoor unit has its own controls.
Outdoor unit positions
On flats and terraced houses, space outside is often the deciding factor. We look at walls, roofs, balconies and yards on the survey and we flag any consent you may need.
Do you need air conditioning in Horndean?
Portable units are often where people start, and why they call us. Portables push their warm air out through a hose in the window, so the window cannot close properly and the noisy part of the unit is in the room. A fixed split system puts the compressor outside.
Keep an eye out for any of the following:
- Too many options and no clear advice
- Old electric heaters you’d like to replace with something more efficient
- Working from home in a room that gets too warm
Homes near Saint Wilfrid's are a good example of where we look up the heritage status of the building before fixing anything to it.
Comparing quotes
- The make and model of any parts or equipment being quoted
- Whether a new circuit is included and who certifies it
- Whether anyone has checked the property or the system first
When something else is needed
Air conditioning cannot fix everything, and we will tell you before any work starts. It won’t put right:
- A ventilation problem rather than a temperature problem
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- Problems with a gas boiler or the radiators
If in doubt, phone 07833 053749 and we will say what we think.
What the work covers

What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes anything from a day for one room to several days for a multi-room or ducted system. The more we can see first, the quicker the visit to Horndean.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Getting ready for the visit
- Keep pets out of the rooms we’re working in
