What we do, step by step
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we have done. Everything the job in Codicote needs is worked out beforehand.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
How to prepare
- Keep pets out of the rooms we’re working in
- Clear the space around the indoor unit, or where it will go
- Make sure we can reach the consumer unit or fuse board
Getting a price
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To start, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Commercial air conditioning in Codicote
Where equipment generates heat around the clock, the cooling has to keep pace. We look at the heat load and how the room is used, and can discuss backup units so one failure doesn’t take everything down. The work covers wall-mounted split systems, ducted systems and server and comms room cooling, and the jobs we see most are fit-outs and refurbishments that need new air conditioning and systems over 12 kW due a TM44 inspection.
In a place like Codicote, commercial air conditioning is often for a shop, a surgery, a pub, an office unit or a farm business. Most need one to four indoor units, sized from a site survey.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Let and managed properties
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
Whether it’s one property or many, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
What you can do yourself, and what needs us
Write down what you notice: 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 of the display helps even more.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
What air conditioning won’t do
Before booking, it helps to know what’s not included:
- Fire strategy sign-off
- Major builder’s work such as new openings in structural walls
- Boiler installation or repair
If in doubt, call 07833 053749 and we’ll say what we think before booking.

Your questions about commercial air conditioning in Codicote
Is air conditioning in Codicote permitted development?
It depends on the property. Central Codicote sits inside the Codicote Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at North Hertfordshire council, typically the authority for Codicote.
Do you cover smaller places like Codicote?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
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 warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. 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.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Are you TM44 assessors?
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.

From one of our customers
“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.”
