About our air conditioning in Northumberland Heath
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. The survey ends with a recommendation and the reasons for it, and the manufacturer’s warranty terms are set out on your quote. When someone in Northumberland Heath asks us for air con, the first questions are normally price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. 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.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Before you call an engineer
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Don’t 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 electrical side needs a competent person. If you need something moved, we can quote for it.
When it’s something else
A few issues sit outside what this work can do:
- Stuffy rooms that need fresh air rather than cooling
- A room that cannot take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
If you’re not sure, just call 07833 053749 or use the quote form and we will give you a straight answer.

What else we do in Northumberland Heath
Air conditioning in Northumberland Heath: local notes
VOA council tax data show about 40% of homes in Northumberland Heath and the neighbourhoods around it date from 1919 to 1939. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Hall Place and Gardens, about 1.8 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Older streets near St Paul's may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.
Northumberland Heath is about 3 miles north-west of Dartford, in Greater London. Homes and businesses alike in Northumberland Heath, we can help with air conditioning.

What the work involves, system by system
Wall-mounted split systems
A wall-mounted split is the most common choice for a single room. One unit inside, one outside, connected by pipework, a cable and a drain, routed as agreed on the survey.
Outdoor unit positions
Where outside space is tight, the outdoor unit position shapes the whole design. We look at walls, roofs, balconies and yards on the survey and we flag any consent you may need.
How it works
You don’t need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. At the end, we tidy up and run through the work with you. A few pictures of the room, the outside wall and the fuse board help us plan a job in Northumberland Heath.
- 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.
- 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
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we are working in
- Move furniture away from the wall where we’ll be working

Advice
Northumberland Heath: your questions answered
Is Northumberland Heath in your area for air conditioning?
We do: Northumberland Heath falls inside our working area. Just ring 07833 053749 or email us with a few details.
Do I need permission to put air conditioning in my flat in Northumberland Heath?
Usually, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
How long will the installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Will you work on another installer’s system?
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.
Is there a survey before the work?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.
