How we handle commercial air conditioning in Cold Christmas
Server rooms and comms rooms need cooling that keeps going. We look at the heat load and how the room is used, and can discuss backup units, so a single fault does not leave the room without cooling. If you’re dealing with planning ahead for the HFC phase-down and server rooms running too warm, we can help.
Around Cold Christmas, there’s usually space for outdoor plant away from the road.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Your questions about commercial air conditioning in Cold Christmas
Do you cover Cold Christmas for commercial air conditioning?
Yes, Cold Christmas is within the area we cover. Tell us a little about the job and we will take it from there.
Will you come out to Cold Christmas?
Yes. Cold Christmas is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will skipping a service affect the warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects and stick to the interval they set.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
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 tell you why.
Do I need planning permission?
Not necessarily. Permitted development can cover a heat pump on a house, including an air-to-air system that heats as well as cools since 2025, provided the conditions are met. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it normally comes up and the survey picks it up. This is general information, not legal advice.

What else we do in Cold Christmas
System by system
Ducted systems
A ducted system hides the indoor unit and feeds air to the room through grilles. They suit spaces where a visible unit is not wanted in retail, hospitality and offices.
Offices
Office cooling has to cope with people, computers, lighting and sunshine. The system is sized for what the space really needs and choose units that suit the ceiling and layout.

Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. Historic England lists about 8 buildings and structures within half a mile of the centre of Cold Christmas, including Fabdens (on North Bank of River Rib) (grade II*). None of this rules air conditioning out. It just means the planning position is checked before anyone suggests a spot for the outdoor unit.

What affects the cost of commercial air conditioning
A fixed price needs a few facts first. We check:
- Whether it’s a one-off job or part of a maintenance contract
- How many units are involved
- The equipment or parts the job needs
The price reflects the work, not guesswork. That is why we look at the job first, from photos or on a survey, and the price is agreed before work begins.
Before you get in touch
There’s no need for technical detail. It helps if you can send:
- Any previous service or F-Gas records
- A short video of any fault, such as a noise or a flashing light
- The fuse board and where it is in the property
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. For a fixed-price quote, call 07833 053749 or drop us a line.
What happens on the day
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes anything from a day or two for a small office to several weeks of phased work on a large building. We agree a date with you and plan the visit to Cold Christmas so we arrive with what’s needed.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- We agree a programme that suits the site, including evening, weekend or phased installation.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- Finally it’s commissioned and handed over, with the refrigerant records and manuals for your files.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Plan for pets to be kept clear during the visit
- Let us know if the units are on a roof, a high wall or in a locked area
Ask for a quote
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Advice
Aftercare tips
Looking after the system is mostly common sense. A few tips:
- Note the 5-yearly TM44 date for systems over 12 kW
- Book a maintenance contract to keep servicing on schedule
- Keep a log for each system
Equipment warranties come from the manufacturer. We go through the manufacturer’s conditions with you, so you know what’s needed.
Keep records of every service, leak check and repair. For systems at or over 5 tCO2e, they’re required.
