How we handle commercial air conditioning in Wych Cross
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. Typical jobs include work raised by a TM44 inspection and comms rooms without enough cooling, on VRF systems, multi-split systems and ceiling cassettes.
For a hall or similar building near Wych Cross, an air-to-air system that responds quickly suits intermittent use.
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 each visit is recorded.

What else we do in Wych Cross
What we do, step by step
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work 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 Wych Cross, tell us about narrow lanes, gates and parking when you book.
- First comes a survey, looking at the building and how it’s occupied.
- You get our recommendation and a fixed price.
- 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
- Mention any parking restrictions near the property
- Have the make and model of any existing unit to hand
- Arrange for someone to be there to let us in

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Safe owner checks
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
What the work involves, 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 isn’t wanted in retail, hospitality and offices.
Hotels and schools
Schools often need installs during the holidays, with the programme agreed well in advance.
When something else is needed
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Gas boiler or heating plumbing work
- Planning permission or landlord consent on your behalf
- Structural alterations to the building
Not sure which it is? You can phone us on 07833 053749 and we will tell you honestly.

Common questions in Wych Cross
Is Wych Cross in your area for commercial air conditioning?
Yes, Wych Cross is within the area we cover. Just call us on 07833 053749 or use the quote form with a few details.
Will air conditioning in Wych Cross need planning permission?
It depends on the property. The half-mile around the middle of Wych Cross holds about 3 listed buildings and structures. 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 the planning department at Wealden council, usually the authority for Wych Cross when it matters.
When is a TM44 inspection required?
Over 12 kW, a TM44 inspection is needed at least every 5 years. The rules are set out on GOV.UK and we’ll help with the system side.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What does the operator have to do under the F-gas rules?
It depends on the system’s tCO2e. From 5 tCO2e, leak checks and records are needed with automatic leak detection at 500 tCO2e and above.
Can you install out of hours?
We do: evening, weekend and phased installation are all possible so the business keeps running. The programme is agreed with your quote.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it, and the quote is based on that.
