About our air conditioning in Castle Green
Most air conditioning needs its own electrical supply from the consumer unit. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across Greater London.
In Castle Green, as across London, the rooms that get hottest are normally under the roof or behind large sunny windows. Many people start with one wall-mounted unit in the room that suffers most, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Landlords, agents and facilities managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side, and the paperwork can go to both.
What an install looks like in Castle Green
About 55% of homes in the Castle Green area were built between the wars, according to VOA council tax data, and about 49% of households live in terraced houses, according to Census 2021 figures. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route. Terraces have little side access, so the outdoor unit normally goes on the rear wall or a flat roof, with the pipe run kept short. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Around St John the Divine, a quick check of the listing and conservation maps is part of planning any install.

Common questions in Castle Green
Do you cover Castle Green for air conditioning?
Yes, Castle Green is within the area we cover. To start, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk with a few pictures.
Can I get a fixed-price quote for air conditioning in Castle Green?
Send us pictures of the room or the system and a few details about the property. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Do I need to service the system to keep the warranty?
For some brands, yes. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you survey before quoting?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
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. Leak checks required by the F-gas rules can be built in for larger systems.

Other services in Castle Green
Do you need air conditioning in Castle Green?
Not everyone is after cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, so it gives out more heat than the electricity it uses. That is how most modern split systems work.
Look out for any of the following:
- A loft conversion that’s too warm to use
- A home office that warms up with screens and equipment
- Expensive direct electric heating
With historic houses such as Eastbury Manor House about 1 mile west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

What air conditioning will not do
An honest diagnosis matters more to us than a booking, so here’s what air conditioning will not do:
- Work that needs permission from a landlord or the council
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- Gas boiler or central heating faults (we do not work on gas boilers)
If in doubt, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and we will say what we think before you book.
What we work on in Castle Green
- VRF systems
- Wall-mounted split systems
- Ceiling cassettes
- Ducted systems
- Air-to-air heat pumps
- Multi-split systems
How it works
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes anything from a day for one room to several days for a multi-room or ducted system, and we tidy up before we leave. Some blocks in Castle Green need contractor details in advance, so tell us what your building needs.
- 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.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Keep pets and children away from the work area
- Mention any roof access, ladders or high-level work
- Tell us about parking and loading
Getting a price
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
Advice
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
