What we do, step by step
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. The work takes from a couple of days for a few cassettes to a planned programme for a whole building. Seeing the property in photos first means the trip to Long Marston can be planned properly.
- You tell us about the building and what’s needed.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- We install around your hours, phased where necessary.
- We commission it, hand it over and can set up a maintenance contract.
Getting ready for the visit
- Keep pets out of the rooms we are working in
- Let us know if the building has a permit or sign-in process
- Unlock any gate, garage or side passage we need
Ask for a quote
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
Advice
About our commercial air conditioning in Long Marston
The business that operates the system has F-gas responsibilities. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We carry out the checks, keep the records and tell you when the next one is due. Typical jobs include server rooms running too warm and systems that need out-of-hours or phased installation, on multi-split systems, VRF systems and ceiling cassettes.
In a village like Long Marston, commercial air conditioning is typically for a pub, a shop, a surgery, a village hall or a rural business. Older buildings may be listed or in a conservation area, so we check the planning side first.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What commercial work looks like in Long Marston
The centre of Long Marston lies within the Long Marston Conservation Area. About 17 listed entries lie within half a mile of central Long Marston, Tower of the Old Church of All Saints (grade II*) among them. That matters for air conditioning: permitted development does not apply within the grounds of a listed building, in a conservation area the outdoor unit cannot go on a wall or roof facing a road, and a unit used only for cooling isn’t covered at all, so we check with the local planning authority (typically Dacorum council) where needed. At about 35 miles from central London, Long Marston sits inside the area we cover across London and the South East.
A bursar or site manager at a school like Long Marston VA Church of England Primary School will want the install planned around the school calendar, and we work to that.

Leave it or put it right?
Small faults in a commercial system can spread to the whole building’s comfort. Regular servicing finds problems early, and keeps the system running the way it was designed to. Small faults tend to grow, so it’s worth dealing with them early.
What you pay depends on the type of system and how many units are involved, the access and what the work involves. We give you a fixed price before work begins, so you know where you stand.

Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
When to call us in Long Marston
Heat builds up in commercial spaces from occupants, equipment, lighting and sunshine and windows alone can’t always shift it. A system sized for the real heat load deals with it.
What we are most often called about:
- Systems that need out-of-hours or phased installation
- Server rooms running too warm
- Offices that get too hot in summer
Churches and halls such as Church of All Saints (Church of England) are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.

Long Marston questions
Is Long Marston in your area for commercial air conditioning?
We do: Long Marston falls inside our working area. Just ring us on 07833 053749 or use the quote form with a few details.
Is Long Marston within the area you cover?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Do you have a 24/7 line?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Do I get paperwork after the visit?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
