FAQs for Dartford
How do I get a quote for air conditioning in Dartford?
The easiest way is to call us on 07833 053749, or email if that’s easier with a few details and photos. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Can you do air conditioning in Dartford?
Yes. We work across London and the South East from our base in East Grinstead, and Dartford is part of that. Get in touch with the details and we reply the same working day.
Can I have air conditioning in a flat?
In many cases, but permissions come first. You’ll typically need the landlord’s or management company’s consent for the outdoor unit and the pipe route, so check the lease. Planning rules for flats are tighter too, and we flag anything that may need permission. This is general information, not legal advice.
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
What warranty do I get?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
How we handle air conditioning in Dartford
Most air conditioning needs its own electrical supply from the consumer unit. Under Part P, a new circuit is notifiable unless a registered competent person does it, and our NICEIC approval means we install and certify it ourselves. Every installation in Dartford begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
Many installs in Dartford can go ahead as permitted development, but listed buildings, conservation areas and flats often need consent first: we tell you at the survey if it applies.
Around Dartford, older homes and newer ones sit side by side, and that changes how the pipework goes in. Older solid walls need more drilling than modern cavity walls, while a loft space can hide pipe runs that would otherwise be on the outside.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.
Air conditioning around Dartford
Central Dartford is inside the Dartford Town Centre Conservation Area. Historic England lists about 29 buildings and structures within half a mile of the centre of Dartford, including Church of the Holy Trinity (grade I). That matters for air conditioning: permitted development doesn’t apply within the grounds of a listed building, in a conservation area the outdoor unit cannot go on a wall or roof facing a road, and a unit used only for cooling is not covered at all, so we check with the local planning authority (usually Dartford council) where needed. The 2021 Census found about 41% of households in terraced houses. With a terrace, the back wall or an extension roof is typically the best place for the outdoor unit.
Hall Place and Gardens, about 2.8 miles west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

In Dartford, that means homes and buildings near The Rose pub, Stone Lodge School and Leigh Academy, among other places. There’s a railway station in Dartford itself: Dartford station.

What happens if it’s left?
New systems now use lower-impact refrigerants. Since 2025, new single split systems with less than 3 kg of refrigerant cannot use F gases with a GWP above 750, so new splits use refrigerants such as R32, with a GWP of 675. Older R410A systems have a GWP of 2088. Small faults tend to grow, so it’s worth dealing with them early.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re not sure what’s needed, give us a ring on 07833 053749 or drop us a line for straight advice and a fixed price.

Honest limits
A few issues sit outside what this work can do:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Building damp that has a structural cause
- An installation that needs consent nobody has given yet

What happens on the day
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes a day or more, depending on the number of rooms, the pipe routes and the access, and we clear up before we go. For a visit in Dartford, tell us how to reach the outside wall or the outdoor unit.
- First comes a site survey, or photos and measurements for a straightforward job.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Getting ready for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area
- Mention any parking restrictions near the property

When to call us in Dartford
Loft rooms and top floors tend to suffer most. The roof takes the full force of the sun, and warm air rises from the floors below, which is why a loft bedroom can still be warm at bedtime.
Any of these is worth a proper look:
- Fans and portables that don’t keep up
- Uncertainty over the right type and size of system
- A study or office that overheats during the day
Close to Dartford station? A small study or box room used for work can typically be cooled with a single indoor unit.
Before booking anyone
