What an install looks like in Dummer
The centre of Dummer lies within the Dummer Conservation Area. Listed buildings are part of the picture here: about 23 within half a mile of the centre, such as Church of All Saints (grade I). None of this rules air conditioning out. It just means the planning position is checked before anyone suggests a spot for the outdoor unit. The Valuation Office Agency’s council tax figures show about 38% of homes across Dummer and its surrounding area were built in 2000 or later, and about 70% of households live in detached or semi-detached houses, according to Census 2021 figures. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. Houses usually have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Homes near Church of All Saints are a good example of where we look up the heritage status of the building before fixing anything to it. Bedrooms under the roof and rooms with big sunny windows are typically the first to overheat, so they’re the usual place to start.

Common questions in Dummer
Is Dummer in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Dummer is part of that. Just give us a ring on 07833 053749 with a few details.
Will you come out to Dummer?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Dummer and across Hampshire. Let us know who the records should go to.
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. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What size air conditioning unit do I need?
Floor area is only part of it. Glazing, orientation, the roof and what goes on in the room all affect it and the survey covers each of them.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.

Before you call an engineer
Write down what you notice: 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 of the display helps even more.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. The work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Work in Dummer is booked in advance at a time that suits you.
- We survey the property, or work from your pictures for a simple job.
- Output, positions and price are settled before anything is booked.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- It’s switched on, checked and handed over with its records.
Preparing for the visit
- Mention any parking restrictions near the property
- Keep pets out of the rooms we are working in
- Let us know if the building has a permit or sign-in process

Related advice
What the work involves, system by system
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, which the condensate drain takes away. Where it can’t fall naturally to a drain, a condensate pump lifts it, and we plan that on the survey.
Outdoor unit positions
Where outside space is tight, the outdoor unit position shapes the whole design. Every option is checked on the survey, and tell you about any permissions you may need.
From one of our customers
“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.”
