Air conditioning in Charlton
Any installation we do in Charlton follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. If you want air conditioning in Charlton, you get one team and one number from survey to sign-off, wherever you are in Hertfordshire.
The outdoor unit position is the biggest single decision: airflow, noise towards neighbours, pipe length and access for servicing all count.
Space outside is rarely the problem in a place like Charlton. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Each manufacturer sets its own warranty period. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

What else we do in Charlton
When it’s something else
It’s worth knowing the limits before booking:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- An installation that needs consent nobody has given yet
If you’re not sure, just give us a ring on 07833 053749 or email us and we will give you a straight answer.
Where we work
- Air-to-air heat pumps
- Multi-split systems

- Ceiling cassettes
How the visit works
If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. For businesses, we can normally work room by room or zone by zone. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. A note on how to find the property and where to park makes a visit to Charlton easier.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Before we arrive
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Make sure we can reach the consumer unit or fuse board
- Arrange for someone to be there to let us in
Ask for a quote
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Advice
Charlton questions
Is air conditioning in Charlton permitted development?
It depends on the property. The Charlton Conservation Area takes in the middle of Charlton. 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 the local planning authority (for Charlton, typically North Hertfordshire council).
Do you cover Charlton for air conditioning?
Yes, Charlton is within the area we cover. To start, phone us on 07833 053749 or use the quote form with a few photos.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded and F-Gas records kept where they apply.
Can I use air conditioning to heat a room?
Usually, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
Can the outdoor unit go on a roof or at ground level?
Wall brackets, ground level and flat roofs are all options, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours and position can affect planning.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Does servicing affect my warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
What affects the cost of air conditioning
Every job gets its own quote. These are the things that affect it:
- Whether it’s a one-off job or part of a maintenance contract
- Which make and model is being fitted or worked on
- How many units are involved
The price reflects the work, not guesswork. That is why we look at the job first, from pictures or on a survey, and the price is agreed before any work starts.
What to send for a quote
To help us quote quickly, send us:
- The outdoor side of the property, including any roof or flat area
- Your installation or service records
- A few pictures of the room and the wall the unit is on, or will go on
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, ring 07833 053749 or email us.
