Do you need commercial air conditioning in Lewisham?

Restaurants and hotels need comfortable rooms for guests and staff. Each area has its own hours and heat load, which affects the type of system and controls we’d suggest.

  • Ageing air conditioning that keeps breaking down

How to choose an air conditioning engineer

Commercial air conditioning in Lewisham

Once a system is in, it needs looking after. A maintenance contract keeps servicing and leak checks on schedule, with the records kept up to date, at a price fixed with your quote. There’s a 24/7 emergency line for breakdowns. We’re often asked to deal with systems that need out-of-hours or phased installation and ageing air conditioning that keeps breaking down, on VRF systems, ceiling cassettes and multi-split systems.

London buildings in Lewisham can have little space for outdoor plant, so roofs, light wells and basements are common positions. VRF systems keep outdoor plant down by serving many rooms from few outdoor units, which helps in dense areas.

Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Safe owner checks

There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.

Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.

The process

The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes as long as the site and the system need, from a short install to a phased project planned around opening hours. A few photos of the room, the outside wall and the fuse board help us plan a job in Lewisham.

  1. It starts with a survey on site, looking at the space, the people in it and the equipment.
  2. The written quote is fixed and lists the plant, where it goes and the order of works.
  3. The work is planned around your opening hours, with out-of-hours or phased work where it helps.
  4. On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
  5. The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.

Getting ready for the visit

  • Mention any parking restrictions near the property
  • Let us know if the units are on a roof, a high wall or in a locked area
  • Clear access to the fuse board

Advice

Questions from Lewisham

Do you cover Lewisham for commercial air conditioning?

Yes, Lewisham is within the area we cover. Tell us a little about the job and we’ll take it from there.

Do I need planning permission for air conditioning in Lewisham?

That depends on the building and where the outdoor unit goes. There’s a conservation area, the Mercia Grove Conservation Area, close to central Lewisham. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Lewisham council, which is normally the planning authority for Lewisham.

Do you protect the property while you work?

Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.

Why use an F-Gas certified company?

Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.

What kind of air conditioning can you install in a business?

Everything from wall-mounted units for single rooms to VRF or VRV systems serving whole buildings. Cassettes and ducted units are common choices for open-plan and visible spaces.

Do I get paperwork after the visit?

Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.

Is there a survey before the work?

Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.

Commercial air conditioning in Lewisham: local notes

Food Standards Agency data counts about 403 cafés, restaurants and staff canteens, about 11 hotels, B&Bs and guest houses and about 48 schools and colleges in and around Lewisham, up to about a mile and a half out. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. The Valuation Office Agency’s council tax figures put about 37% of homes in and around Lewisham before 1919, and the 2021 Census found about 69% of households live in flats. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.

For a school like St Saviour's Catholic Primary School, air conditioning work is best done out of term.
