Air conditioning in Richmond, done properly

The best installations are planned before a single hole is drilled. We look at each room’s size, glazing, orientation and use, and we agree the unit positions and the route for the pipes, cable and drain before you get a fixed-price quote. Air conditioning installation in Richmond starts with a site survey, then a fixed-price quote that names the make and model.

London homes in Richmond can be short of outside space, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. Neighbours’ windows and noise matter as much as appearance when we choose the position, and we plan the pipe route so it’s as short and tidy as the building allows.

Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Richmond questions

Is Richmond in your area for air conditioning?

We do: Richmond falls inside our working area. To start, give us a ring on 07833 053749 or drop us a line with a few photos.

Is air conditioning in Richmond permitted development?

The answer turns on the property and where the outdoor unit would sit. The Richmond Hill Conservation Area takes in the middle of Richmond. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Richmond, normally Richmond-Upon-Thames council).

How long does air conditioning installation take?

It takes a day or more, depending on the number of rooms, the pipe routes and the access. We confirm the time when we quote so there are no surprises.

Do you protect the property while you work?

We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.

How do I know what size unit to get?

It depends on the room, not only its floor area. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.

Do you look at the job first?

Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.

Which type of air conditioning is best?

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 to call us in Richmond

Many people try a portable unit first. A portable unit has to vent its warm air through a hose out of a window, which lets some heat back in, and its compressor sits in the room with you. A fixed split system puts the compressor outside.

Any of these is worth a proper look:

  • A loft conversion that is too warm to use
  • A study or office that overheats during the day
  • Uncertainty over the right type and size of system

Around The Vineyard Church, a quick check of the listing and conservation maps is part of planning any install.

Before booking anyone

  • Which brand and model they’re proposing, and why
  • What happens if the job turns out to be different on the day
  • Whether the manufacturer’s warranty depends on regular servicing

Questions to ask before you book

System by system

Outdoor unit positions

The outdoor unit can go on a wall bracket, on the ground or on a flat roof, whatever suits the building and the route. It needs airflow around it and room for servicing.

Multi-split systems

A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The route from the outdoor unit to each room is the main variable.

Safe owner checks

Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.

Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.

Air conditioning in Richmond: the local picture

About 54% of homes across Richmond and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 60% 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 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.

If you commute from Richmond station and work from home on other days, one wall-mounted unit in the home office is often all that is needed.

Richmond is about 5 miles south-west of Kensington, in Greater London. Properties in Richmond get the same service as everywhere we cover: a look at the job first, a fixed-price quote and written records at the end. Richmond is one of 764 places in Greater London we cover for homes and businesses. London is in our area too, around 9 miles away.

Recent work in Richmond

Richmond Hill, Richmond (TW10)

Property
A detached georgian house with river views.
Work carried out
Installation of a Mitsubishi Electric Zubadan multi-split system serving four bedrooms, the study and the living room: six indoor units in total. The Georgian listed building required a pre-application planning discussion, which confirmed the outdoor unit could be positioned in the lower garden. All pipework was concealed within the building fabric.
Outcome
The installation was one of the most complex we have completed, requiring careful coordination with the listed building requirements and a high level of finish in the Georgian interior. The client: who works from home and has family visiting regularly: described it as transformative for year-round living comfort.

What we do, step by step

We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures 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 or more, depending on the number of rooms, the pipe routes and the access. Photos of the room and where the outdoor unit could go let us plan most of a visit to Richmond in advance.

  1. We start by looking at the rooms, the walls and where the outdoor unit can go.
  2. You receive one fixed figure covering the kit, the fitting and the positions we agreed.
  3. On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
  4. Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
  5. Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.

Preparing for the visit

  • Keep pets and children away from the work area
  • Mention any managing agent or landlord rules we need to follow
  • Clear the space around the indoor unit, or where it will go
