Streatham is our home turf — our base is in SW16 — so it gets our fastest response and our most local knowledge. Along Streatham High Road, one of the longest high streets in London, the mansion flats and purpose-built blocks have top-floor, single-aspect rooms that trap heat under the roof and behind sealed windows, and we supply and install split-system and multi-room air conditioning across SW16 and SW2, sized to the room and fitted cleanly, so those flats stay comfortable through the summer. On heat-pump models they warm the same rooms in winter as well.
In a managed block the outdoor condenser has to sit where the freeholder or managing agent allows — a balcony or an agreed external position — and we handle that sign-off as part of the job. Every unit is sized before we quote: the room's dimensions, glazing and aspect decide the BTU rating, so a flat behind a large single-aspect window gets cooling that actually holds the temperature rather than a unit that runs flat out and never quite catches up on the hottest days. We handle the condensate drainage and electrical connection and commission the system before we hand it over.
Up around Telford Park and Streatham Hill, the larger period houses have several rooms to cool across different floors, where a multi-split from a single condenser keeps the exterior tidy and lets each room run independently. The many Victorian and Edwardian conversions off the High Road bring hot upper-floor flats that a discreet split handles well. We fit for homeowners, landlords and the letting agents who manage so much of SW16, from one room to a whole house — around the corner and with a price agreed up front. Being based here, we can usually survey quickly and, for a straightforward split, fit sooner than areas further out.

Why Streatham homes and landlords rely on us for air conditioning installation
Being based in SW16 means Streatham gets our quickest response, and we know its housing well. The mansion flats and purpose-built blocks strung along Streatham High Road are prime cooling territory: top-floor rooms bake under the roof, thick walls hold the heat, and large single-aspect windows give little cross-flow, so a quiet wall split brings the controllable cooling these flats lack. The one thing to plan is the condenser — in a managed block along the High Road its position needs the managing agent's or freeholder's sign-off, which we arrange before we start.
Up around Telford Park and Streatham Hill, the larger period houses are natural candidates for whole-house cooling: with rooms on several floors and heat rising up tall stairwells, a multi-split zoned across bedrooms, studies and reception rooms handles the lot from one tidily sited condenser. The Victorian and Edwardian terraces off the High Road, many split into upper and lower flats, rarely have loft or duct space, so a discreet surface-mounted split with neat external pipework is the sensible route. Every unit is sized to its room, and being local we can survey quickly and fit without fuss. We pressure-test and commission every system and show you the filter-cleaning that keeps it efficient, and heat-pump models warm the same rooms in winter.
About air conditioning installation
Air conditioning installation covers supplying and fitting split-system and multi-room cooling — sizing each unit to the room, mounting the indoor and outdoor units and running the pipework, drainage and electrical connection.
It is for homeowners, landlords and offices that need reliable cooling in rooms which overheat — from a single hot bedroom or home office to a whole-house or commercial system.
Signs you might need air conditioning installation
- Bedrooms or home offices that overheat in summer and stay warm late into the night
- Top-floor, loft or south-facing rooms that trap heat and become hard to use
- Fans and portable units that never quite cope on the hottest days
- Sealed or non-opening windows that offer little real ventilation
- A shop, office or server room that needs steady, comfortable temperatures
- Rising running costs from an inefficient or undersized existing unit
What we cover
- Wall-mounted split-system air conditioning
- Multi-room and multi-split installations
- Correct BTU / kW sizing for each room
- Indoor and outdoor unit mounting and pipework
- Condensate drainage and electrical connection
- Testing, commissioning and handover

Air Conditioning in Streatham — FAQs
How quickly can you get to a job in Streatham?
Streatham is where we are based, so we can usually get to local jobs quickly — often the same day for smaller repairs, depending on our schedule.
Do you know the older properties common in Streatham?
Yes. Many Streatham homes are Victorian or Edwardian conversions, and we are used to the quirks that come with them — from original woodwork to older plumbing.
Do you look after converted flats and mansion blocks in Streatham?
Yes. A lot of Streatham's Victorian and Edwardian terraces have been split into flats, and there are mansion blocks and purpose-built flats along the High Road. We are used to the shared soil stacks, communal plumbing and older pipework that come with them.
Do you work on the larger period houses around Streatham Hill and Telford Park?
We do. The bigger houses up towards Streatham Hill and Telford Park often need sympathetic upkeep — sash windows, tired plaster, redecoration and older heating — and we handle that everyday work with one team covering every trade.
How do I know what size air conditioner I need?
The right size depends on your room's dimensions, ceiling height, how much sun it gets and how many people use it. Use our BTU calculator on this page for a quick estimate, then we will confirm the exact size on a site visit before quoting.
What is a BTU and why does it matter?
BTU (British Thermal Units) measures cooling capacity. An undersized unit will run constantly and never quite cool the room, while an oversized one wastes energy and cycles on and off. Getting the size right keeps you comfortable and running costs low.
Do you install both the indoor and outdoor units?
Yes. A standard split system has an indoor unit on the wall and an outdoor condenser. We mount both, run the pipework and cabling between them, sort the condensate drainage and make the electrical connection.
Can you cool more than one room?
Yes. A multi-split system runs several indoor units from one outdoor condenser, so you can cool multiple rooms independently. We will size and plan the layout as part of your quote.
Do you service and maintain air conditioning too?
We can install and maintain your system. Regular filter cleaning and checks keep it efficient and extend its life — ask us about a maintenance visit.
Where does the outdoor condenser unit go?
The outdoor unit sits on an external wall, a balcony or at ground level, positioned to keep the pipe runs short and any noise away from living space. In a flat or managed block you may need the freeholder's or managing agent's permission for its location, and we will help you plan a tidy, agreed position.
