Air conditioning for Lee Common and the surrounding area: a survey or diagnosis, a fixed price, careful work and proper paperwork. Ask us for a fixed-price quote.
- Old electric heaters you’d like to replace with something more efficient
- An old system that needs replacing
- A home office that warms up with screens and equipment
Let and managed properties
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Facilities teams in offices, schools and public buildings book us too in Lee Common and across Buckinghamshire. Work can be phased by floor, zone or building to keep disruption down.
About our air conditioning in Lee Common
A new system normally needs a dedicated circuit from the fuse board. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. Most enquiries from Lee Common start with one hot room: a bedroom, a home office or a loft conversion. A single-room split system is often the answer, from £1,200 + VAT.
The outdoor unit position is the biggest single decision: airflow, noise towards neighbours, pipe length and access for servicing all count.
Around Lee Common, many people choose a system that heats as well as cools, which suits rooms the main heating does not reach well, such as a garden room or loft.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Before you call an engineer
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Why deal with it now?
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. R410A, used in many older systems, has a GWP of 2088. An early booking makes the visit to Lee Common easier to arrange.
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.

- A 24/7 emergency line
- Enquiries answered the same working day
- MCS certified for heat pumps
- A site survey and a fixed-price quote
How the visit works
If the system has to be off for part of the visit, we tell you before we start so it does not catch you out. In a business, work can often be done one area at a time. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. We plan the trip to Lee Common around you.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- 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.
- 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.
Preparing for the visit
- Keep pets and children away from the work area
- Tell us about parking and loading
- Tell us about any building rules, permits or sign-in
Getting a quote
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. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
Advice
Air conditioning in Lee Common: local notes
The last census (2021) found about 80% of households in detached or semi-detached houses. Houses normally have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Living close to St Mary's? Some older properties in parts like that are protected, and the survey finds out whether yours is. Cholesbury Manor House, about 2.3 miles north-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

Questions from Lee Common
Do you cover Lee Common for air conditioning?
Yes, Lee Common is within the area we cover. To start, ring us on 07833 053749, or email if that’s easier with a few pictures.
Is planning permission needed for air conditioning in Lee Common?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Lee Common holds about 4 listed buildings and structures. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with Buckinghamshire council, which is typically the planning authority for Lee Common.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are also Checkatrade members.
How long does air conditioning installation take?
A single-room system is usually fitted in a day. Multi-room and ducted systems take longer, depending on the pipe routes and access, and we tell you how long on the quote.
Which type of air conditioning is best?
It depends on the rooms and the building. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
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. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
