Our air conditioning service in RH4
Most modern split systems run as heat pumps, so they can heat as well as cool. The Energy Saving Trust recognises that air-to-air heat pumps often go by the name air conditioning, so a well-chosen unit can be useful in winter as well as summer. The work covers ducted systems, multi-split systems and VRF systems, and the jobs we see most are commercial rooms that are too warm for staff and too many options and no clear advice.
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
What you’ll pay
The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account and give you a fixed price before any work starts.

Landmarks near Dorking
In Dorking, that means homes and buildings near The Ashcombe School, St Paul's CofE (Aided) Primary School and Church of St Paul. Also close by are The Ashcombe School (0.6 miles north), The Wheatsheaf Public House (within half a mile north-west), Pippbrook House (0.5 miles north) and Deepdene Terrace (0.5 miles east). The closest station to Dorking is Dorking Deepdene station, roughly 0.6 miles north. Nearby you’ll also find Mesolithic Museum (3.9 miles south-west) and Headley Court (4.8 miles north-east). For a walk, there’s Reigate Heath and Box Hill.
Air conditioning around RH4
In RH4, as across England, the same permitted development rules apply: an air-to-air system that heats as well as cools can be permitted development on a house, but cooling-only units, listed buildings and outdoor units facing a road in conservation areas need more care.
An F-Gas certified company does the refrigerant side, while NICEIC approval covers the electrical work, in RH4 as everywhere else.
Dorking: Close to Dorking Deepdene station? A small study or box room used for work can typically be cooled with a single indoor unit. Polesden Lacey (roughly 2.7 miles north-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Let filters dry fully before you put them back
- Report drips, noises or error codes straight away
- Wash or vacuum the filters as the manual describes
- Do not cover or box in the outdoor unit
An annual service keeps the system running efficiently, and some manufacturers make regular servicing a condition of their warranty. We will remind you when it’s due, so it does not get forgotten.
Have the system serviced once a year. A service cleans what you cannot reach and picks up faults before they stop the system and keeps the warranty paperwork right where servicing is a condition.
Pricing air conditioning in RH4
You’ll get a fixed price before any work starts. It’s based on:
- What state the existing equipment is in
- The number of rooms, units or zones
- Whether we need access equipment for high-level work
- The equipment or parts the job needs
Our prices page shows typical ranges, but each job is priced on what it involves. For a fixed-price quote, call 07833 053749 or write to us at info@aircondoctor.co.uk, and we’ll talk you through it.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Any error code or flashing light on the display
- The paperwork from the last service, if you have it
- Where the outdoor unit is, or where you’d like it
- Your consumer unit or fuse board
Here’s what helps us quote: where the property is and what kind of building it is, a few pictures, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, phone 07833 053749 or drop us a line.
What we are called out for in RH4
Everything that uses electricity in a room ends up as heat. A small office or a busy room can warm up fast with equipment and people in it, even on a mild day.
What we are most often called about:
- A business premises that overheats in summer
- A study or office that overheats during the day
- A loft conversion that is too warm to use
- Fans and portables that do not keep up
Let and managed properties
Keeping records across a portfolio is half the battle. Every visit is written up, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
RH4 questions
How quickly will you reply?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
What does it cost to install air conditioning?
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 pictures.
Which brands do you work with?
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’ll take it from there.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
Is planning permission needed for the outdoor unit?
Not necessarily. On a house, air-to-water heat pumps and, since 2025, air-to-air systems that heat as well as cool can be permitted development if they meet the conditions. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it typically comes up, and we tell you at the survey. This is general information, not legal advice.
