Air conditioning for homes and businesses in New Malden

Not sure what you need, or where it would go? Just phone us on 07833 053749 or send an email with photos of the rooms and the outside of the property, and we’ll reply the same working day to arrange a survey or a quote. If you want air conditioning in New Malden, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork.

Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. A single wall-mounted unit in the worst room is often where people start, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Keeping the system healthy

Aftercare is straightforward, and it helps at the next service:

  • Close windows and doors while the system is cooling
  • Avoid setting it far colder than you need
  • Never run the system with the filters out

If anything is not right after we’ve gone, call us on the same number. Let us know what’s happening and any error code, and we will talk it through with you.

Report drips, noises or error codes early. A drip, a noise or a flashing light is often an early sign of a fault, and early repairs are normally simpler.

Common questions in New Malden

Can I fit air conditioning in New Malden without planning permission?

It depends on the property. There’s a conservation area, the Groves Conservation Area, close to central New Malden. 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 necessary, we check with Kingston-Upon-Thames council, which is normally the planning authority for New Malden.

Is New Malden in your area for air conditioning?

Yes. New Malden is one of the places we cover. Get in touch with the details and we reply the same working day.

Who is responsible for leak checks?

Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.

How quickly will you reply?

The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.

Should I choose wall-mounted, ducted or cassette?

The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.

Does air conditioning need its own electrical supply?

Most systems need their own supply from the consumer unit. Under Part P, a new circuit has to be notified unless a registered competent person does it, and as NICEIC approved contractors we install and certify it as part of the job.

Is there a survey before the work?

Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.

What an install looks like in New Malden

The Valuation Office Agency’s council tax figures show about 40% of homes in the New Malden area date from 1919 to 1939. Homes of that age usually 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.

Around New Malden Baptist Church, a quick check of the listing and conservation maps is part of planning any install. About 1.6 miles north-east stands Southside House. Listed homes in any area need consent first, so tell us if yours is one.

What affects the cost of air conditioning

A fixed price needs a few facts first. We check:

  • The brand, model and parts involved
  • Whether it’s a simple split or a larger system
  • One-off work versus a regular service cycle

Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we will go through it with you.

What to send for a quote

There’s no need for technical detail. Just send:

  • The make and model of the system, from the label
  • Wide pictures of the room or the existing unit
  • Your consumer unit or fuse board

Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.

How it works

The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes a day or more, depending on the number of rooms, the pipe routes and the access, and we clear up before we go. Some blocks in New Malden need contractor details in advance, so tell us what your building needs.

  1. We start by looking at the rooms, the walls and where the outdoor unit can go.
  2. Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
  3. Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
  4. The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
  5. We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.

Before we arrive

  • Clear a path to the units and the space around them
  • Make sure we can reach the consumer unit or fuse board
  • Unlock any gate, garage or side passage we need

Getting a price

Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To start, phone 07833 053749, or email if that’s easier.

What you can do yourself, and what needs us

Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.

Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring us on 07833 053749 or send an email.

What a customer said

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
