Air conditioning installation in Hamsey
Think of it as diagnose, treat and sign off: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. Most enquiries from Hamsey start with one hot room: a bedroom, a home office or a loft conversion. That is normally a single wall-mounted split, from £1,200 + VAT.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the condensate drained away safely.
Space outside is rarely the problem in a place like Hamsey. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork, because it helps with any later warranty question.

The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. The visit takes anything from a day for one room to several days for a multi-room or ducted system. Somewhere like Hamsey, it helps to know about lanes, gates and where to park.
- 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.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Clear a path to the units and the space around them
- Mention any parking restrictions near the property
- Make sure we can reach the consumer unit or fuse board

What else we do in Hamsey
Air conditioning in Hamsey: local notes
About 37% of households live in terraced houses, according to Census 2021 figures. With a terrace, the back wall or an extension roof is typically the best place for the outdoor unit.
Living close to The Parish Church of St Peter? Some older properties in parts like that are protected, and the survey finds out whether yours is. About 1.9 miles south stands Anne of Cleves House. Listed homes in any area need consent first, so tell us if yours is one.
Hamsey is about 1 mile north of Lewes, in East Sussex. From the centre of Hamsey to the outskirts, we cover air conditioning, from a single room to a whole building. 289 places in East Sussex are on our list. Brighton, roughly 7 miles off, has its own page on this site.
Not far from Hamsey, a recent job of ours was on High Street, Lewes (BN7), about 1 mile south: installing a Fujitsu wall-mounted split system in the retail area, with the outdoor unit positioned in the rear courtyard to preserve the listed street frontage. Read more
Postcode districts we cover here: BN8. Close by, we work in Offham (1 mile south-west), South Malling (1 mile south), Lewes (1 mile south), Cliffe (2 miles south) and Southover (2 miles south). Further out, we also cover Eastbourne (14 miles south-east), Seaford (9 miles south-east), Hailsham (11 miles east) and Crowborough (13 miles north-east).
Near you in Hamsey
In Hamsey, that means homes and buildings near Railway Land, Priory School and The Blacksmiths Arms. For rail, the closest station is Cooksbridge station, roughly 0.8 miles north-west of the centre. A little further out are Lewes Castle (1.6 miles south) and Lewes Victoria Hospital (1.5 miles south). Open spaces near Hamsey include Malling Down and Offham Hill.
What happens if it’s left?
The outdoor unit’s position is worth getting right first time. A good position keeps noise down and leaves room for servicing, and it can affect whether planning permission is needed. We agree it with you on the survey. A system that’s left with a fault, or without a service, usually costs more to run.
The cost depends on the system and the number of rooms or units, the access and what the work involves. We give you a fixed price before any work starts, so there are no surprises.

Hamsey questions
Do you cover Hamsey for air conditioning?
Yes, Hamsey is within the area we cover. Just call us on 07833 053749 or send an email with a few details.
Will air conditioning in Hamsey need planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Hamsey holds about 6 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 necessary, we check with the planning department at Lewes council, usually the authority for Hamsey.
Do you survey before quoting?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
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.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
What owners can safely do
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
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 makes our diagnosis quicker, and a photo or a short video of the display is even better.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
