What an install looks like in Portslade
Portslade lies within about 1 mile of the sea. Salt air is hard on outdoor units, so we site them out of the worst of the sea wind where we can, and can suggest models with corrosion-protected coils where the manufacturer offers them. Valuation Office Agency council tax records date about 46% of homes in Portslade and the neighbourhoods around it to the post-war years, 1945 to 1972. We check the wall construction on homes of that age, as it decides how the pipework goes through.
Homes near St Nicolas Church are a good example of where we look up the heritage status of the building before fixing anything to it. Plenty of people near Fishersgate station split the week between the train and a spare room, and that spare room is often the first to get a unit.

Air conditioning in Portslade
Most air conditioning needs its own electrical supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. When someone in Portslade 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.
Many installs in Portslade can go ahead as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.
In a smaller place like Portslade, most installs are in houses and cottages, often with gardens, which typically leaves room for an outdoor unit. The wall type and how the electrics reach the unit are often the main things to check.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

After we’ve gone
How well a system lasts depends on use and care. We suggest:
- Flag any change in how the system sounds or performs
- Keep the room closed while it runs
- Have the system serviced once a year
We recommend an annual service, and some manufacturers make regular servicing a condition of their warranty. We’ll remind you when it’s due, so it doesn’t get forgotten.
Have the system serviced once a year. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early and keeps the warranty paperwork right where servicing is a condition.

FAQs for Portslade
Is air conditioning in Portslade permitted development?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Portslade Old Village Conservation Area, close to central Portslade. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Brighton and Hove council, typically the authority for Portslade.
Do you cover smaller places like Portslade?
Yes. Portslade is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
How long will the installation take?
It takes anything from a day for one room to several days for a multi-room or ducted system. The survey tells us how long your installation will need, so you can plan around it.
Does servicing affect my 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. Either way, keep a record of every service.
Owner checks or an engineer?
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Landlords, agents and facilities managers
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.
For anyone managing more than one building, we can quote and plan the work across all of them. Every address has its own paperwork, so the files stay tidy.
What a customer said
“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.”
