When it’s something else
In fairness, there are a few things this work will not fix:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- Problems with a gas boiler or the radiators

Air con installers in Hersham
Good air conditioning starts with the right system in the right place. Each room is assessed for its size, windows, direction and how it’s used, and we agree the unit positions and the route for the pipes, cable and drain, all before the price is fixed. When someone in Hersham asks us for air con, the first questions are typically price and who will fit it. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
Getting the size right matters more than the brand: we look at the room’s size, windows, insulation and use before choosing a unit.
Homes around Hersham are mostly houses, many with gardens, which typically leaves room for an outdoor unit. The bigger questions are the wall construction and the route back to the consumer unit.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

What happens on the day
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer, and we clear up before we go. Let us know how to reach the outside wall or outdoor unit at your property near Hersham.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Getting ready for the visit
- Let us know where we can park and unload
- Clear the space around the indoor unit, or where it will go
- Have the make and model of any existing unit to hand

Your questions about air conditioning in Hersham
Do you cover smaller places like Hersham?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is planning permission needed for air conditioning in Hersham?
It depends on the property. There’s a conservation area, the Hersham Village Conservation Area, close to central Hersham. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with Elmbridge council, which is typically the planning authority for Hersham.
Which type of system should I choose?
It depends on the rooms and the building. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. The survey ends with a recommendation and the reasons.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How does the warranty work?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking and we’ll gladly show you ours.
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.

Larger air conditioning systems in buildings need more than servicing: 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.
From a single flat to a whole estate, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
Air conditioning in Hersham: the local picture
About 60% of households live in detached or semi-detached houses, according to Census 2021 figures. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Around Church of St Peter, a quick check of the listing and conservation maps is part of planning any install. About 1.4 miles south-east stands The Homewood. Listed homes in any area need consent first, so tell us if yours is one.

Looking after it afterwards
Simple habits make a real difference. Our advice:
- Leave space around the outdoor unit
- Keep the indoor unit’s filters clean
- Have the system serviced once a year
The work area is left tidy: sheets removed, packaging cleared up and pipe holes sealed. Outside, the pipework is neatly fixed and protected, so the job looks as tidy as it works.
Regular filter cleaning is the simplest thing you can do. Blocked filters cut airflow and make the system work harder, so it uses less electricity for the same comfort.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
