Commercial air conditioning London: what Climate Flow does

Climate Flow Limited installs, services and repairs commercial air conditioning across London and surrounding areas: offices, shops, restaurants, gyms, schools and hotels. We work on split, multi-split, cassette, ducted and VRF/VRV systems, from a single shop unit to a building with many rooms, and we offer 24/7 emergency callouts when a system breaks down.

This page covers commercial work. For every type of system we fit, homes included, see our air conditioning services.

Which type of commercial air conditioning suits your premises?

The right system depends on the size and layout of the space, how many rooms need cooling, where an outdoor unit can go and how the pipework can be routed. The site survey settles it. These are the main options:

  • Split system. One outdoor unit connected by refrigerant pipework to one indoor unit. It suits a single room, such as a small office or a shop floor.
  • Multi-split. One outdoor unit serving several indoor units, for premises with a few rooms to cool.
  • Cassette. A cassette unit is an indoor air conditioning unit set into the ceiling. It is a common choice for shops, restaurants and offices with suspended ceilings; our cassette air conditioning page explains the installation.
  • Ducted. A ducted system is an indoor unit hidden in the ceiling void that delivers air through ducts and grilles, so only the grilles show in the room.
  • VRF/VRV. VRF (variable refrigerant flow) divides a building into zones and moves refrigerant between one outdoor unit and several indoor units. Mitsubishi Electric states that up to 50 indoor units can be connected to a single outdoor unit in its City Multi VRF range, which is why VRF suits larger multi-room buildings. Our VRF and VRV air conditioning page covers it in detail.

Who we fit commercial air conditioning for

Offices, shops, restaurants, gyms, schools and hotels all have rooms that warm up with people, lighting, equipment and summer sun. Health and safety law requires employers to keep the temperature in an indoor workplace at a comfortable level, as the Health and Safety Executive sets out, and air conditioning is one way a business can manage that.

Places we've worked include Courtyard by Marriott. For a recent job, read how we installed a Mitsubishi Electric split system for a newly refurbished retail unit in Hillingdon.

What happens on site

  1. Survey. An engineer looks at the rooms to be cooled, where the outdoor units can go, the routes for refrigerant pipework and condensate drainage (condensate is the water an indoor unit removes from the air), and the electrical supply.
  2. Quote. You receive a no-obligation quote setting out the system, the scope of work and the programme.
  3. Installation. Indoor units, outdoor units, pipework, drainage and controls go in, planned around how the premises trade.
  4. Commissioning and handover. The system is tested and set up, and we show the people on site how to use the controls.

Commercial air conditioning installation can be planned outside trading hours, in the evenings and at weekends, so the business can keep working while the system goes in.

Signs your system needs an engineer

  • The system runs but the room does not cool.
  • Water drips from an indoor unit.
  • An error code shows on the controller or the indoor unit.
  • The outdoor unit does not start, or keeps stopping.
  • A new noise or smell when the system runs.

What does the law ask of a business with air conditioning?

A business that uses stationary air conditioning is responsible for having it checked for F gas leaks. How often the checks happen depends on how much F gas the system holds; for the smallest charge band that needs checks, GOV.UK guidance on F gas leak checks sets at least once every 12 months.

Only certified companies may install, repair, maintain or decommission equipment containing F gas, and anyone who handles it must hold a personal qualification, as GOV.UK's F gas certification guidance explains. Climate Flow is F-Gas certified.

Larger systems carry a second duty. In England and Wales, where an air conditioning system has an effective rated output of more than 12kW, the person who controls it must have its accessible parts inspected by an energy assessor at intervals not exceeding five years, under the Energy Performance of Buildings (England and Wales) Regulations.

Regular servicing keeps a system's leak-check records in order and lets an engineer spot wear before it becomes a breakdown. Our maintenance contracts set out planned visits for each site.

Brands we install and service

Common questions

What types of commercial air conditioning are there?
The main types of commercial air conditioning are split systems for a single room, multi-split systems with one outdoor unit serving several rooms, cassette units set into the ceiling, ducted systems hidden in the ceiling void, and VRF or VRV systems for larger multi-room buildings. A site survey shows which type suits the premises.
Can commercial air conditioning be installed outside trading hours?
Yes. Climate Flow can plan commercial air conditioning installation outside trading hours, in the evenings and at weekends, so that shops, restaurants, offices and gyms keep working while the system goes in. The timing is agreed with the site after the survey, once the scope of the installation is known.
Does commercial air conditioning need an energy inspection?
In England and Wales, an air conditioning system with an effective rated output of more than 12kW must have its accessible parts inspected by an energy assessor at intervals not exceeding five years. The duty sits with the person who controls the system, and an assessor confirms whether a particular system is in scope.
How often must commercial air conditioning be checked for F gas leaks?
Businesses that use stationary air conditioning are responsible for having it checked for F gas leaks. How often depends on how much F gas the system holds. GOV.UK guidance sets at least once every 12 months for the smallest charge band that needs checks, and larger charges are checked more often.
Which brands of commercial air conditioning does Climate Flow install and service?
Climate Flow installs and services commercial air conditioning from Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Fujitsu, Toshiba, Panasonic and Samsung. The engineer confirms the make and model of an existing system at the survey or on the first visit, and the work is carried out by F-Gas certified engineers.
How long does a commercial air conditioning installation take?
The time a commercial air conditioning installation takes depends on the system type, the number of indoor units, the pipework, the routes for condensate (the water the indoor units remove from the air) and access on site. Climate Flow sets out the scope and the programme in the quote after a site survey, so no installation time is given before the premises have been seen.
