Commercial air conditioning near Keston

Commercial air conditioning in Keston

Most businesses need to keep trading while the work is done. Work can be done in the evening, at weekends or in phases, so the building keeps running. The timing is set out with your quote. The work covers ceiling cassettes, server and comms room cooling and wall-mounted split systems, and people most often call us about older systems on refrigerants that are getting scarcer and systems over 12 kW due a TM44 inspection.

For a business in Keston, the legal side matters too: F-gas leak checks on larger systems, and TM44 inspections where total cooling output is over 12 kW. We keep the F-gas records and flag what’s coming up.

Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Why deal with it now?

A system that can’t cope on the hottest days affects everyone in the building. Planning a replacement or upgrade before the summer is easier than reacting in a heatwave. Getting the work done in Keston before summer avoids the busiest weeks.

The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before work begins, so there are no surprises.

What happens on the day

On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes a few days for a small shop or office, longer for VRF across several floors. Before a visit in Keston, we ask where the van can stop and how we reach the outdoor unit.

  1. We survey the site and talk through how each area is used.
  2. You get our recommendation and a fixed price.
  3. We agree the timing, with evening, weekend or phased work as needed.
  4. We install the units, pipework, drainage, electrics and controls.
  5. Commissioning and handover follow, with the F-gas records and manufacturer paperwork.

Preparing for the visit

  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Let us know where the consumer unit is
  • Let us know where we can park and unload

Advice

FAQs for Keston

Will air conditioning in Keston need planning permission?

There’s no single answer: the building and the outdoor unit position decide it. The centre of Keston is in the Keston Village Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Keston, normally Bromley council).

Is Keston in your area for commercial air conditioning?

Yes. Keston is one of the places we cover. To start, ring 07833 053749 or use the quote form with a few photos.

How often is a TM44 inspection needed?

Systems with an effective rated output over 12 kW need a TM44 inspection at least every 5 years. An accredited energy assessor carries it out, and we can prepare the system and act on the report.

Will skipping a service affect the warranty?

It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.

How does the warranty work?

Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.

Do you provide F-Gas records?

Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.

Can I do the refrigerant work myself?

No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.

What the work involves, system by system
