What we do, step by step
Every visit follows the same order: check the plan with you, put the dust sheets down, do the work, check the system and explain it all to you. On site, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Visits to a place like Hartley are planned ahead, so we arrive with what the job needs.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Keep pets and children away from the work area
- Find the manual or the paperwork for the system, if you have it
- Tell us about any building rules, permits or sign-in

Air conditioning for homes and businesses in Hartley
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be and we talk you through it on the survey. People searching for “air con near me” in Hartley want two things: a sensible price and someone qualified. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
In a smaller place like Hartley, most installs are in houses and cottages, often with gardens, so there’s typically space for the outdoor unit. The bigger questions are the wall construction and the route back to the consumer unit.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What air conditioning won’t do

- Stuffy rooms that need fresh air rather than cooling
- Draughts and missing insulation

Air conditioning around Hartley
About 42% of homes in and around Hartley date from 1945 to 1972, according to Valuation Office Agency council tax records, and about 76% of households live in detached or semi-detached houses, according to Census 2021 figures. We check the wall construction on homes of that age, as it decides how the pipework goes through. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Around Church of Saint Mary, a quick check of the listing and conservation maps is part of planning any install. Close to Longfield station? A small study or box room used for work can usually be cooled with a single indoor unit.

Before you call an engineer
Keep a note of anything odd: 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.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Your questions about air conditioning in Hartley
Can I fit air conditioning in Hartley without planning permission?
The answer turns on the property and where the outdoor unit would sit. A conservation area takes in the middle of Hartley. 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 is not allowed under those rules. If there’s any doubt, we ask the planning department at Dartford council, normally the authority for Hartley.
Do you cover Hartley for air conditioning?
Yes, Hartley is within the area we cover. Tell us a little about the job and we will take it from there.
Where does the outdoor unit go?
Wall brackets, ground level and flat roofs are all options, wherever the pipe route, airflow and servicing access work best. Noise near bedrooms and boundaries is part of the decision, and the position can affect planning.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
How much is air conditioning for one room?
It depends on the rooms, the system and the pipe route, but a single-room split is typically £1,200–£2,200 + VAT. Where you sit in the range depends on pipe length, access, electrics and the model, and commercial systems are priced after a survey.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone and we will gladly show you ours.

Pricing air conditioning in Hartley
The diagnosis comes before the price. The main factors are:
- What state the existing equipment is in
- The number of rooms, units or zones
- Whether the existing supply is suitable
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- The postcode and whether it’s a home, flat or business
- The remote or wall controller showing any error
- A few photos of the room and the wall the unit is on, or will go on
Photos are the fastest route to a quote: 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 many jobs can be priced from that.
