Questions from Hartfield
Do you cover smaller places like Hartfield?
Yes. Hartfield is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I fit air conditioning in Hartfield without planning permission?
It depends on the property. Central Hartfield sits inside the Hartfield Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Wealden council, which is typically the planning authority for Hartfield.
Which brands do you work with?
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.
Can you do our TM44 air conditioning inspection?
TM44 inspections are carried out by accredited energy assessors, which we are not. We prepare systems for inspection and carry out the work the report recommends.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Commercial air conditioning in Hartfield, done properly
Many sites need more than cooling. Air conditioning systems can heat as well as cool, and we also install ventilation and MVHR for a joined-up system. Common call-outs are for older systems on refrigerants that are getting scarcer and server rooms running too warm, across ducted systems, VRF systems and multi-split systems.
Around Hartfield, commercial jobs tend to be pubs, shops, halls, surgeries and farm or rural businesses. Older buildings may be listed or in a conservation area, so we check the planning side first.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

How the visit works
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. In a business, work can often be done one area at a time. The work takes from a couple of days for a few cassettes to a planned programme for a whole building. Work in Hartfield is booked in advance at a time that suits you.
- We survey the site and talk through how each area is used.
- 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.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Make sure we can reach the consumer unit or fuse board
- Let us know if the units are on a roof, a high wall or in a locked area
How to get a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.

What the work involves, system by system
Ducted systems
Ducted systems need space above the ceiling and access for servicing for filters, drain and fan to be serviced.
Server and comms rooms
IT equipment produces heat around the clock, so the cooling has to run continuously. We size the system on the heat load.

What owners can safely do
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Do you need commercial air conditioning in Hartfield?
Offices and shops often gain heat from people, lighting, computers and sun through the windows and windows alone cannot always shift it. A system sized for the real heat load deals with it.
Common reasons people call us include:
- F-gas leak checks and records that are overdue
- New tenancies needing cooling and heating
- Commercial systems near the end of their life
If you look after a church or hall such as The Parish Church of St Mary, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

A customer’s words
“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.”
