What we’re called out for in Green Cross
Many businesses call us when an older system is struggling or failing. Parts become harder to find and the system cannot keep up so replacement starts to make more sense than repair.
If any of these sounds familiar, it’s worth a diagnosis:
- Fit-outs and refurbishments that need new air conditioning
- F-gas leak checks and records that are overdue
- Staff complaining about the temperature
For a surgery or clinic in the Haslemere and District Hospital area, a planned maintenance contract keeps the system clean and its records up to date.
Before booking anyone
- Whether the company is F-Gas certified, and whether you can check it
- Whether the manufacturer’s warranty depends on regular servicing
- The make and model of any parts or equipment being quoted
About our commercial air conditioning in Green Cross
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. Typical jobs include IT rooms that need resilient cooling and missing F-gas records for commercial systems, across wall-mounted split systems, VRF systems and ceiling cassettes.
If you run a village hall or similar building near Green Cross, heating and cooling that warms up fast suits a space used on and off, and it can heat as well as cool.
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.

What else we do in Green Cross
What owners can safely do
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
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.
Green Cross questions
Is Green Cross in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Green Cross is part of that. Just call 07833 053749 or send an email with a few details.
Is planning permission needed for air conditioning in Green Cross?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Green 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 Waverley council, normally the authority for Green Cross when it matters.
Can you work around our opening hours?
We do: evening, weekend and phased installation are all possible to keep disruption down. We set out the timing before work starts.
How often is a TM44 inspection needed?
At over 12 kW, inspections are due at least every 5 years. The inspection is done by an accredited assessor, and we do the follow-up work.
What kind of air conditioning can you install in a business?
We install wall-mounted, cassette, ducted, multi-split and VRF systems. The right one depends on the building and how it’s used.
Do you carry out TM44 inspections?
We do not carry out the inspection itself, as it needs an accredited energy assessor. Our part is getting the system ready and doing the follow-up work.
Do you provide ongoing maintenance for businesses?
Yes, with visits planned around the site. There’s also a 24/7 emergency line for breakdowns.
What happens on the day
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can normally work room by room or zone by zone. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. Photos of the existing unit help with repairs and servicing in Green Cross.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- We commission the system, record the refrigerant details and hand over the controls and documents.
How to prepare
- Name a contact who can meet us at the agreed time
- Make sure we can reach the consumer unit or fuse board
- Have the make and model of any existing unit to hand

Ducted systems
Ducted systems need space above the ceiling and access for servicing so filters and drains can be reached.
Server and comms rooms
IT equipment produces heat around the clock and the cooling must keep up all year. The design is based on the equipment’s heat output.
