Why it’s worth doing now in Hexton

Air conditioning for homes and businesses in Hexton
A single-room split system is typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, and commercial VRF systems are priced after a survey. Air con, air conditioning, a split system: whatever you call it, in Hexton it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Space outside is rarely the problem in a place like Hexton. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

What else we do in Hexton
What happens on the day
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes anything from a day for one room to several days for a multi-room or ducted system. For a place like Hexton, the timing is set with you and the travel is our side of the planning.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Preparing for the visit
- Clear a path to the units and the space around them
- Let us know if the units are on a roof, a high wall or in a locked area
- Have the make and model of any existing unit to hand

Advice
Hexton questions
Can you do air conditioning in Hexton?
We do: Hexton falls inside our working area. Just phone 07833 053749 or drop us a line with a few details.
Is Hexton within the area you cover?
Yes. Hexton is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Can I use air conditioning to heat a room?
Most of the time, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
Will I get records for the system?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
What the work involves, system by system
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill and kept as tidy as the building allows.
Outdoor unit positions
Noise is part of the decision: away from bedroom windows and neighbours’ windows where possible and fitted so vibration doesn’t carry into the building. It can also affect whether planning permission is needed.
Air conditioning around Hexton
Hexton’s centre falls inside the Hexton Conservation Area. On the National Heritage List, around 13 entries fall within 0.5 miles of the middle of Hexton; Church of St Faith (church of England) (grade II*) is one. Heritage protection changes what an install can involve, so the survey looks at your address first and tells you plainly whether consent is likely. About 77% of households live in detached or semi-detached houses, according to the 2021 Census. Detached and semi-detached houses usually have space for the outdoor unit, and several rooms can share one on a multi-split.
Living close to Church of St Faith (Church of England)? Some older properties in parts like that are protected, and the survey finds out whether yours is. About 4.3 miles west stands Harlington Manor. Listed homes in any area need consent first, so tell us if yours is one.

What affects the quote in Hexton
Every job gets its own quote. This is what makes a difference:
- What state the existing equipment is in
- What kind of system it is
- The number of rooms, units or zones
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.
What to send for a quote
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- The postcode and whether it’s a home, flat or business
- A photo of the consumer unit with the cover closed
- Any error code or flashing light on the display
The quickest way to a quote is to send pictures: 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 simple jobs can often be priced without a visit.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
