Common questions in Dial Post
Do you cover Dial Post for air conditioning?
Yes, Dial Post is within the area we cover. Get in touch with the details and we reply the same working day.
Will air conditioning in Dial Post need planning permission?
That depends on the building and where the outdoor unit goes. Around 6 listed entries sit within 0.5 miles of central Dial Post. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Dial Post, normally Horsham council) when it matters.
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
How much is air conditioning for one room?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. The price includes supply, installation, commissioning and F-Gas documentation, and we fix it after a survey or from your photos.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Air conditioning installation in Dial Post
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. Air conditioning installation in Dial Post starts with a site survey, followed by a fixed-price quote with the brand, model and every part of the job set out.
For a home in or near Dial Post, an air-to-air system can cool in summer and heat in the cooler months, which suits rooms the main heating doesn’t reach well, such as a garden room or loft.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

The process
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes about a day for a single-room system, longer for multi-room and ducted systems, and we tidy up before we leave. Visits to Dial Post are agreed with you in advance and planned so the job can be finished in one trip where possible.
- We survey the property, or work from your pictures for a simple job.
- Output, positions and price are settled before anything is booked.
- We protect the area, then fit both halves of the system.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- It’s switched on, checked and handed over with its records.
Preparing for the visit
- Clear a path to the units and the space around them
- Let us know where we can park and unload
- Find the manual or the paperwork for the system, if you have it

When something else is needed
We’d rather tell you now than sell you work that will not help, so here are the limits:
- An installation that needs consent nobody has given yet
- 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
If in doubt, ring us on 07833 053749 or use the quote form and we will say what we think before booking.
Where we work
- Air-to-air heat pumps
- Wall-mounted split systems
- Ceiling cassettes

Air conditioning around Dial Post
The 2021 Census found about 74% of households in detached or semi-detached houses. 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.
Bedrooms under the roof and rooms with big sunny windows are typically the first to overheat, so they’re the usual place to start. Many split systems run in heating mode too, which makes them useful outside summer.

Keeping the system healthy
A little care keeps the system in better shape. Our advice:
- Keep the F-Gas records, commissioning details and warranty information together
- Keep the outdoor unit clear of leaves, plants and clutter
- Have the system serviced once a year
Questions after the installation go to the same number. Let us know what’s happening and any error code, and we will talk it through with you.
Give the outdoor unit room to breathe. Leaves, plants, bins and stored items around it restrict the airflow, and the system has to work harder as a result.
What happens if it’s left?
If you are thinking about air conditioning for a property in Dial Post, there’s no need to wait for a heatwave. Installation takes anything from a day for one room to several days for a multi-room or ducted system, and the date is agreed with you after you’ve accepted the fixed price. A system that’s left with a fault, or without a service, typically costs more to run.
Typical ranges are on our prices page, but each job is priced on what it involves. Call for a fixed-price quote, and we’ll explain what it covers.
