Why deal with it now?
The outdoor unit’s position is worth getting right first time. Placing it well keeps noise away from bedrooms and boundaries and makes servicing easier, and it can affect whether planning permission is needed. We agree it with you on the survey. In London, hot spells can bring a rush of calls, so planning the work in Southfields before summer avoids the wait.
What you pay reflects the actual work. That is why every job is looked at first, and why the quote is fixed before any work starts.

How we handle air conditioning in Southfields
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Air con, air conditioning, a split system: whatever you call it, in Southfields it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the condensate drained away safely.
In a London area like Southfields, many of the homes we are asked about are flats, maisonettes and terraced houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. A freeholder or managing agent often has a say in a flat, and we can give you the details they’ll ask for.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Looking after your system
To keep the system working properly:
- Report drips, noises or error codes right away
- Clean the filters every few weeks when the system is in heavy use
- Keep the room closed while it runs
We clear up before we go: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Pipework outside is covered in trunking or insulated and neatly fixed as agreed on the survey.
Book an annual service. A service cleans what you can’t reach and picks up faults before they stop the system, and it keeps any warranty servicing conditions in order.

Southfields questions
Do I need permission to put air conditioning in my flat in Southfields?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can you do air conditioning in Southfields?
We do: Southfields falls inside our working area. Get in touch with the details and we reply the same working day.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Which type of air conditioning is best?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Do I get paperwork after the visit?
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.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Can the outdoor unit go on a roof or at ground level?
Wall brackets, ground level and flat roofs are all options, chosen for the pipe route, airflow and access. We also think about noise near bedrooms and neighbours and position can affect planning.
The process
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. For a job in Southfields, tell us about parking, permits and access to the building when you get in touch.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Getting ready for the visit
- Make sure we can reach the consumer unit or fuse board
- Mention any parking restrictions near the property
- Keep pets out of the rooms we are working in
Getting a price
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, ring us on 07833 053749 or fill in the contact form.

What an install looks like in Southfields
About 57% of homes across Southfields and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and Census 2021 figures found about 62% of households live in flats. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Older streets near St John the Divine may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. If you work from home near Earlsfield station, a home office that overheats is one of the easiest rooms to cool.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what air conditioning won’t do:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Stuffy rooms that need fresh air rather than cooling
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
Not sure which it is? You can ring us on 07833 053749 or fill in the contact form and we will tell you honestly.
