System by system
Offices
Office cooling has to cope with people, computers, lighting and sunshine. We size the system for the actual heat load with units that fit the layout.
F-gas records and TM44
For systems from 5 tCO2e upwards, the operator is responsible for leak checks and records. We carry out the checks and provide the records.
How we handle commercial air conditioning in Charlton
The right system depends on the building. Wall-mounted splits suit small offices and single rooms, cassettes suit open ceilings, ducted units hide away in ceiling voids, and VRF or VRV serves many rooms from shared outdoor units. We explain the options and why we’d choose one over another. The work covers ceiling cassettes, multi-split systems and ducted systems, and people most often call us about installs that must fit around trading hours and leak check schedules that have slipped.
In a village like Charlton, commercial air conditioning is typically for a pub, a shop, a surgery, a village hall or a rural business. Older buildings may be listed, so planning comes first.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

What happens on the day
Our engineers 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 the electrics are made safe before any panel comes off. The work itself takes as long as the site and the system need, from a short install to a phased project planned around opening hours. For a village like Charlton, tell us about narrow lanes, gates and parking when you book.
- First comes a survey, looking at the building and how it’s occupied.
- We recommend a system and send a fixed-price quote.
- The programme is agreed, including any out-of-hours or phased work.
- We install the units, pipework, drainage, electrics and controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
Before we arrive
- Move furniture away from the wall where we’ll be working
- Let us know where we can park and unload
- Make sure we can reach the consumer unit or fuse board
How to get a quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule.
A bursar or site manager at a school like Highbury Infant School and Nursery will want the install planned around the school calendar, and we work to that. Healthcare premises near Lister Hospital need air conditioning that’s easy to clean and maintained on a schedule.

Common questions in Charlton
Is Charlton in your area for commercial air conditioning?
Yes. Charlton is one of the places 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 Charlton?
That depends on the building and where the outdoor unit goes. The centre of Charlton is in the Charlton Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to North Hertfordshire council, which is normally the planning authority for Charlton when it matters.
What’s the price of air conditioning for a business?
After a site survey, with a fixed-price quote. The number of zones, the type of system, access and timing all play a part.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Do you carry out TM44 inspections?
We don’t carry out the inspection itself, as it needs an accredited energy assessor. What we do is prepare the system and carry out the improvements the report suggests.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
