Air conditioning in
New Southgate N11
A Daikin multi-split we fitted here is the photograph at the top of this page. Interwar semis, Victorian terraces towards Bowes Park, and narrow side returns that decide where the condenser goes. From £2,400 fitted, and we work in N11 regularly.

A job we did in N11
New Southgate N11
Daikin multi-split condenser
Wall-mounted on brackets rather than stood on the ground, which is usually what a narrow side return leaves you, and the refrigerant lines dropped in a single trunked run.
We install, service and repair air conditioning across New Southgate N11. A single room is £2,400 to £3,200 fitted and a whole house is £8,400 to £11,300, with a free survey and a written price that does not change.
A multi-split serving two or three rooms from one condenser mounted on the flank wall, refrigerant lines dropped in a single trunked run. Two days.
What the housing in New Southgate means for the job
New Southgate sits on the Barnet, Enfield and Haringey boundaries and its housing reflects all three. The bulk is interwar semi-detached, with a side return that is often narrower than the same house in Enfield, which is why wall-mounted condensers are more common here than ground-level ones. Towards Bowes Park and Arnos Grove there are Victorian and Edwardian terraces, and around the station there is newer flatted development. The narrow side return is the recurring theme, and it is the reason the job in the photograph above went on brackets rather than on a base.
Worth knowing before you book. A wall-mounted condenser needs anti-vibration mounts and a wall that will take it. On a rendered blockwork extension that is worth checking properly rather than assuming, and it is part of the survey.

Heat pump
N14
Southgate
Vaillant aroTHERM plus air source heat pump
A gas boiler out and a heat pump in over three days, a few streets from our own base. The unit stands beside the garden decking on anti-vibration feet, with the pipework taken along the fence line.

N22
Wood Green
Samsung monobloc air source heat pump
Stood on a levelled base built up out of the border rather than on soil, so the feet stay out of standing water and the unit does not settle out of level over a winter.

North Finchley
Samsung air source heat pump with hydrobox
Heat pump and hydrobox both outside in the side passage, which keeps the whole system out of the house and leaves the cupboard the old boiler used.

Hornsey
Vaillant aroTHERM plus air source heat pump
The owner wanted the indoor equipment out of the living space, so it went into the loft. The outdoor unit has its own base in the garden. Three days, gas boiler out.

Heat pump and solar
N21
Winchmore Hill
Air source heat pump with roof-mounted solar
The panels sit across the rear pitch and the heat pump at the side of the house, which is the pairing that lets the pump run on its own generation through the middle of the day.

Mitsubishi Ecodan air source heat pump
An Ecodan stood off the boundary fence far enough that the fan discharge is not bouncing straight back off it, which is what makes a badly sited unit sound louder than it is.

EN4
Cockfosters
Vaillant aroTHERM plus 7 kW air source heat pump
Replaced an old gas boiler in three days. Raised on feet over a gravel bed at the side of the garden, so the defrost water drains away rather than pooling round the base.

Cascade pair of air source heat pumps
Two machines in cascade on a flat roof, flow and return in insulated copper with isolating valves on each leg, so one can be shut down and worked on while the other keeps the building warm.

See if it paysAir conditioning in New Southgate: common questions
Can the outdoor unit go on the wall?
Often it has to, and it is a perfectly good position when it is done properly: proper brackets, anti-vibration mounts and enough clearance in front of the coil.
It adds £250 to £600 over a ground-level position, mostly in brackets and labour.
How many rooms can one outdoor unit do?
Commonly two to five, depending on the model and on how much output the rooms need at once. The photograph on this page is a multi-split condenser.
Each room after the first adds about £2,245 rather than another whole system.
