Air conditioning in Farnborough, done properly
Single-room systems are 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. Supply, installation, commissioning and F-Gas documentation are all included, with commercial and VRF systems priced after a survey. A lot of the calls we get from Farnborough are about one room that is too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
A typical install in Farnborough is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the drain run planned so it never drips where it shouldn’t.
Homes around Farnborough typically have room outside for an outdoor unit. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
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.

Questions from Farnborough
Is air conditioning in Farnborough permitted development?
That depends on the building and where the outdoor unit goes. Central Farnborough sits inside the Farnborough Conservation Area. Permitted development only covers heat pumps that are not 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 West Berkshire council, usually the authority for Farnborough.
Can you do air conditioning in Farnborough?
Yes. We work across London and the South East from our base in East Grinstead, and Farnborough is part of that. Just phone 07833 053749 with a few details.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Do I get paperwork after the visit?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.

What we do, step by step
On the day, we arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. The work itself takes about a day for a single-room system, longer for multi-room and ducted systems. For a place like Farnborough, the timing is set with you and the travel is our side of the planning.
- 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.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Keep pets and children away from the work area
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Make sure we can reach the outdoor unit, or where it will go

Homes in Farnborough and air conditioning
Census 2021 figures found about 83% 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.
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed. If your home is in one of the older streets near Church of All Saints, it’s worth checking whether it’s listed or in a conservation area before an install.

Keeping the system healthy
After the visit, a few habits help:
- Let filters dry fully before you put them back
- Use moderate settings for comfort and economy
- Wash or vacuum the filters as the manual describes
You get the paperwork that matters: the commissioning details, the F-Gas records and the manufacturer’s warranty information. Keep them with the manual as they’re needed for servicing and any warranty question.
Clean the filters regularly, not just at the service. Blocked filters cut airflow and make the system work harder, so it uses less electricity for the same comfort.
How the job changes from property to property
Pipework and condensate drains
Cooling produces water as the air is dried, which the condensate drain takes away. Where it cannot fall naturally to a drain, a condensate pump lifts it and we allow for that in the quote.
Wall-mounted split systems
For one room, a wall-mounted split is often the simplest answer. One unit inside, one outside, connected by pipework, a cable and a drain, routed as agreed on the survey.
What affects the cost of air conditioning
The quote reflects the job in front of us. We take into account:
- Which make and model is being fitted or worked on
- Access, including height, roofs and ladders
- Whether it’s a one-off job or part of a maintenance contract
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed price.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- The address and the type of property
- A close-up of the unit’s label showing the model number
- Your installation or service records
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To start, ring 07833 053749 or email us.
