About our air conditioning in Horsemere Green
Most modern split systems run as heat pumps, so they can heat as well as cool. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning, so a well-chosen unit can be useful in winter as well as summer. Air con, air conditioning, a split system: whatever you call it, in Horsemere Green it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Around Horsemere Green, many people choose a system that heats as well as cools, which suits rooms the main heating doesn’t reach well, such as a garden room or loft.
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 so it’s to hand next time.

FAQs for Horsemere Green
Is planning permission needed for air conditioning in Horsemere Green?
It depends on the property. Historic England lists about 5 buildings and structures within half a mile of the centre of Horsemere Green. 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 isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Horsemere Green, usually Arun council).
Is the coast a problem for outdoor units in Horsemere Green?
It can, as Horsemere Green is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Whose job is it to check the system for leaks?
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.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and AirCon Doctor is certified.
What the work involves, system by system
Pipework and condensate drains
After the pipework is fitted, the refrigerant circuit is pressure tested and evacuated, which keeps moisture and air out of the circuit. The results go into the commissioning records.
Wall-mounted split systems
Bedrooms, offices and living spaces are where wall-mounted units are most often fitted. We choose the position for even airflow and easy filter access rather than blowing straight at the bed or desk.
Air conditioning around Horsemere Green
Horsemere Green is within about 1 mile of the coast. Salt air is hard on outdoor units, so we site them out of the worst of the sea wind where we can, and can suggest models with corrosion-protected coils where the manufacturer offers them. VOA council tax data show about 39% of homes in Horsemere Green and the neighbourhoods around it were built in 2000 or later, and the 2021 Census found about 62% of households in detached or semi-detached houses. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Homes near The Parish Church of St Mary are a good example of where we look up the heritage status of the building before fixing anything to it. Bedrooms under the roof and rooms with big sunny windows are typically the first to overheat, so they’re the usual place to start.

Why it’s worth doing now in Horsemere Green
Fans and portables move warm air around rather than removing it. A properly installed split moves heat outside, keeps the noisy parts out of the room and most of the time heats too, so it works for you in winter as well. A system that’s left with a fault, or without a service, typically costs more to run.
The price reflects the work, not guesswork. That’s why every job is looked at first, and the price is agreed before we start.

What else we do in Horsemere Green
How we price air conditioning
A fixed price needs a few facts first. We look at:
- Whether the existing supply is suitable
- The type of system, from a single split to a larger system
- How many units are involved
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.
Before you get in touch
Photos let us diagnose from a distance. The most useful are:
- The address and the type of property
- Where the outdoor unit is, or where you’d like it
- Wide pictures of the room or the existing unit
