Air conditioning installation in Sepham Heath
Any installation we do in Sepham Heath follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. When someone in Sepham Heath asks us for air con, the first questions are usually 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: the survey covers room size, glazing, insulation and how the room is used, so the unit is not too big or too small.
Homes around Sepham Heath 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.
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 every service is written up.

What else we do in Sepham Heath
The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes a day or more, depending on the number of rooms, the pipe routes and the access. Somewhere like Sepham Heath, 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.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- 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.
Preparing for the visit
- Move furniture away from the wall where we will be working
- Clear access to the fuse board
- Mention any parking restrictions near the property

Different systems, different jobs
Offices, shops and commercial rooms
Offices and shops usually need several units and sensible central controls. We size for the people, equipment and glazing in the space and we plan the installation around your opening hours where we can.
Outdoor unit positions
Outdoor units are fitted on wall brackets, at ground level or on a flat roof, depending on the property and the pipe route. It needs airflow around it and room for servicing.
When to call us in Sepham Heath
Some people come to us for heating rather than cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, so it gives out more heat than the electricity it uses. Most modern split systems work this way.
Look out for these signs:
- Too many options and no clear advice
- Commercial rooms that are too warm for staff
- Portable units that are noisy and barely cope
Around Otford Lane Mission Church, a quick check of the listing and conservation maps is part of planning any install.
Before booking anyone
- Whether the price is fixed or an estimate
- Proof of F-Gas company certification
- Whether you get F-Gas records where refrigerant is involved
Questions from Sepham Heath
Is Sepham Heath within the area you cover?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Is Sepham Heath in your area for air conditioning?
Yes, Sepham Heath is within the area we cover. To start, phone us on 07833 053749 with a few pictures.
Who is responsible for leak checks?
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 will work out which band applies to yours.
Can air conditioning heat my home as well?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before any work starts, and we tidy up as we go. At the end, we clear up and show you what we have done.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
Looking after your system
Here’s the after-treatment advice, short and simple:
- Keep the outdoor unit clear of leaves, plants and clutter
- Tell us if the unit starts to leak, rattle or show a code
- Use moderate settings for comfort and economy
We recommend an annual service, and some manufacturers make regular servicing a condition of their warranty. We can remind you when it’s due if you’d like.
Clean the filters regularly, not just at the service. Clean filters keep the air moving and help the system work as designed, which costs you more to run.
A customer’s words
“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.”
