Air conditioning for South Hampstead

Air conditioning for homes and businesses in South Hampstead

We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, 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, it’s the job we do every week across Greater London.

In South Hampstead, as across London, the rooms that get hottest are usually under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.

Any work on the refrigerant circuit is recorded: 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.

What happens on the day

We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes anything from a day for one room to several days for a multi-room or ducted system. Photos of the room and where the outdoor unit could go let us plan most of a visit to South Hampstead in advance.

  1. First comes a site survey, or photos and measurements for a straightforward job.
  2. We size the system for each room, then send a fixed-price quote with the units and where they go.
  3. The units go up and the pipework, cable and condensate drain are run neatly between them.
  4. Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
  5. The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.

How to prepare

  • Let us know if the units are on a roof, a high wall or in a locked area
  • Let us know if the building has a permit or sign-in process
  • Clear access to the fuse board

How to get a quote

For a fixed-price quote, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk with the address and a few details about the rooms or units involved. A few pictures make it quicker. We reply to enquiries the same working day.

Pricing air conditioning in South Hampstead

Every job gets its own quote. This is what makes a difference:

  • The brand, model and parts involved
  • The type of system, from a single split to a larger system
  • Whether the existing supply is suitable

What you pay depends on the system and the number of rooms or units, the access and what the work involves. We give you a fixed price before any work starts, so there are no surprises.

What we need to know

Before you ask for a quote, gather:

  • Any error code or flashing light on the display
  • Where the property is and what kind of building it is
  • Any previous service or F-Gas records

Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

What air conditioning cannot fix

We won’t sell you work that doesn’t address the problem, so these are the things it won’t cover:

  • An installation that needs consent nobody has given yet
  • Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
  • A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)

If you are not sure, just phone us on 07833 053749 or drop us a line and we’ll give you a straight answer before booking.

What the work covers

  • Wall-mounted split systems
  • Ceiling cassettes
  • Ducted systems
  • VRF systems
  • Multi-split systems
  • Air-to-air heat pumps

System by system

Ceiling cassettes

Cassettes are good at even airflow across a large floor area with just a grille visible in the ceiling.

Outdoor unit positions

On flats and terraced houses, space outside is often the deciding factor. We look at walls, roofs, balconies and yards on the survey, and tell you about any permissions you may need.

Homes in South Hampstead and air conditioning

Valuation Office Agency council tax records put about 47% of homes in South Hampstead and the neighbourhoods around it before 1919, and the last census (2021) found about 90% of households live in flats. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder typically 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.

Plenty of people near South Hampstead station split the week between the train and a spare room, and that spare room is often the first to get a unit. Winfield House (roughly 0.9 miles south-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

South Hampstead: your questions answered

Can you fit air conditioning in a London flat in South Hampstead?

Often, yes, but the lease and the freeholder typically have a say. 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.

Is air conditioning in South Hampstead permitted development?

There’s no single answer: the building and the outdoor unit position decide it. Central South Hampstead is a short walk from the Belsize Park Conservation Area. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with Camden council, which is usually the planning authority for South Hampstead.

Should I choose wall-mounted, ducted or cassette?

Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.

When will I hear back?

On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.

Can I use air conditioning to heat a room?

Yes, most modern split systems run as heat pumps, so they heat as well as cool. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.

What accreditations do you have?

F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.

Do you work on all makes?

The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
