Air conditioning across N21: what to expect
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and our NICEIC approval means we install and certify it ourselves. The work covers wall-mounted split systems, air-to-air heat pumps and ceiling cassettes, and people most often call us about a study or office that overheats during the day and not knowing which system, size or brand to choose.
Each visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, check the system and explain it all to you. The visit itself takes about a day for a single-room system, longer for multi-room and ducted systems.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
What affects the price in N21

Air conditioning across N21
Our air conditioning work across N21 takes in places such as Enfield, Southgate and Enfield Chase and the smaller places around them. We cover every place we list for N21, 8 in all.
London and the South East cover everything from city flats to rural cottages. We are F-Gas certified, NICEIC approved and MCS certified for heat pumps.
Winchmore Hill: Bruce Castle, about 2.6 miles south-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Around Holy Trinity, a quick check of the listing and conservation maps is part of planning any install.
Leave it or put it right?
If you’re thinking about air conditioning for a property in N21, there’s no need to wait for a heatwave. The installation takes a day or more, depending on the number of rooms, the pipe routes and the access, and the date is agreed with you after you’ve accepted the fixed price.
Questions to ask before you book
- What’s in the price and what isn’t
- How extra work would be agreed if they find something unexpected
- Whether they hold F-Gas company certification, not just individual qualifications
- How VAT is shown, and which rate applies
Safe owner checks
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Rented and managed buildings
We also work for facilities teams in offices, schools and public buildings across Greater London. Larger buildings can be done in stages to keep disruption down.
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
Signs you need air conditioning
In shops, offices and restaurants, the heat comes from customers, staff, equipment and lighting as well as the sun. Keeping staff and customers comfortable is typically what prompts the call, and some rooms need cooling for the equipment as much as the people.
Common reasons people call us include:
- A system on old refrigerant that’s due for replacement
- A study or office that overheats during the day
- Fans and portables that do not keep up
- An office, shop or restaurant that’s uncomfortable for staff and customers
N21 questions
Which type of system should I choose?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
How do you size the system?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count, and we take them all into account on the survey.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
How long does air conditioning installation take?
A single-room system is normally fitted in a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
