Felden questions
Do you cover smaller places like Felden?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do I need planning permission for air conditioning in Felden?
That depends on the building and where the outdoor unit goes. Around 11 listed entries sit within 0.5 miles of central Felden. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with Dacorum council, which is normally the planning authority for Felden.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Is air conditioning possible in a flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent, and we check the options on the survey. This is general information, not legal advice.
Which type of system should I choose?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling, which we check on the survey.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will tell you what to do first.
Do I need a new electrical circuit?
Typically, yes. The fuse board is checked on the survey, and any electrical work goes on the quote and we install and certify the circuit as NICEIC approved contractors.
Air con installers in Felden
We approach an installation much as a doctor approaches a patient: survey first, install second, commission and hand over last. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. Most split systems we fit in Felden are reversible: in heating mode they work as an air-to-air heat pump, which is why many owners use theirs all year.
In a smaller place like Felden, most installs are in houses and cottages, often with gardens, so there’s normally space for the outdoor unit. The wall type and how the electrics reach the unit are often the main things to check.
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.

Looking after it afterwards
Systems last better with the right care. We suggest:
- Keep the handover documents somewhere safe
- Book an annual service
- Never run the system with the filters out
An annual service keeps the system running efficiently, and some manufacturers make servicing a warranty condition. We will remind you when it’s due, so it does not get forgotten.
Regular filter cleaning is the simplest thing you can do. Clean filters keep the air moving and help the system work as designed, which costs you more to run.
What an install looks like in Felden
VOA council tax data date about 64% of homes in and around Felden to the post-war years, 1945 to 1972, and the last census (2021) found about 40% of households in terraced houses. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. Terraces have little side access, so the outdoor unit usually goes on the rear wall or a flat roof, with the pipe run kept short.
High Elms Manor, about 3.4 miles south-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Homes near Church of St Mary are a good example of where we look up the heritage status of the building before fixing anything to it.
Felden is about 2 miles south of Hemel Hempstead, in Hertfordshire. Whatever kind of property you have in Felden, we can help with air conditioning.

What happens on the day
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. Around Felden, access is typically simple, though gates and garden access are worth mentioning.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Mention any roof access, ladders or high-level work
- Make sure we can reach the outdoor unit, or where it will go
Ask for a quote
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Different systems, different jobs
Offices, shops and commercial rooms
Commercial rooms often need more than one unit and controls that suit how the space is used. We size for the people, equipment and glazing in the space and we plan the installation around your opening hours where we can.
Electrical supply
The fuse board is looked at during the survey, so the quote covers any electrical work needed. An older board may need extra work, and we explain why if so.
What a customer said
“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.”
