What happens on the day
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. Before we leave, the area is tidied and we explain what we’ve done. For a village like Walkern, tell us about narrow lanes, gates and parking when you book.
- 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.
- We install around your hours, phased where needed.
- We commission it, hand it over and can set up a maintenance contract.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know where we can park and unload
- Keep pets out of the rooms we are working in

Commercial air conditioning for homes and businesses in Walkern
Commercial air conditioning is a big part of what we do, for businesses in Walkern and the rest of Hertfordshire. Offices, shops, restaurants, hotels, schools and server rooms all come with different demands, and each one gets a system chosen for how the space is used. The work covers VRF systems, multi-split systems and ceiling cassettes, and the jobs we see most are F-gas leak checks and records that are overdue and installs that must fit around trading hours.
In a village like Walkern, 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.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

FAQs for Walkern
Do you cover smaller places like Walkern?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Can I fit air conditioning in Walkern without planning permission?
It depends on the property. The centre of Walkern is in the Walkern Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the planning department at East Hertfordshire council, usually the authority for Walkern.
What kind of air conditioning can you install in a business?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. The right one depends on the building and how it’s used.
Are you TM44 assessors?
No, the inspection needs an accredited energy assessor. We can prepare for the inspection and put right what it finds.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
What does the operator have to do under the F-gas rules?
The duties depend on how much refrigerant the system holds. Systems at or above 5 tCO2e need leak checks and records with automatic leak detection at 500 tCO2e and above.
Managing agents and facilities teams in Walkern
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so the files stay tidy.
From a single flat to a whole estate, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.

Keeping the system healthy
To keep the system working properly:
- Call about warning signs straight away
- Plan replacements before old systems fail
- Keep plant areas tidy
If anything does not feel right after the install, ring us on 07833 053749 or send an email and we’ll come back to it. Our 24/7 emergency line covers breakdowns.
A maintenance contract keeps servicing and F-gas checks on schedule. We agree the visits and the price with your quote.
What owners can safely do
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and give us a ring on 07833 053749, or email if that’s easier.
Never try to top up, release or handle refrigerant yourself. 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. A suspected leak is our job, not yours.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
