What commercial work looks like in Southsea
Southsea is within about 1 mile of the coast. For a business near the sea, outdoor plant position and corrosion protection are part of the design. Food Standards Agency records list about 230 restaurants, cafés and canteens, about 20 hotels and guest houses and about 35 schools and colleges within about 1.5 miles of central Southsea. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. About 74% of homes across Southsea and its surrounding area were built before 1919, according to VOA council tax data, and about 57% of households live in terraced houses, according to the last census (2021). In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind.
For a school like Craneswater Junior School, air conditioning work is best done out of term.
Southsea is about 2 miles south of Portsmouth, in Portsmouth. We cover Southsea for commercial air conditioning, along with the rest of Portsmouth. In Portsmouth alone we list 19 places, and Southsea is one. You can also see our page for Worthing, roughly 29 miles from Southsea.
Not far from Southsea, a recent job of ours was on East Street, Chichester (PO19), about 13 miles east: installing a Daikin wall-mounted unit in the dining area and a second unit serving the kitchen pass area.
Jobs in PO5, PO4 and PO1 are looked at, quoted and booked the same way as anywhere else. You will find streets such as Bath Road, Liss Road and Beach Road, each of them within reach. Neighbouring places we cover include Milton (1 mile north-east), Fratton (1 mile north), Kingston (1 mile north), Landport (1 mile north-west) and Baffins (2 miles north). We also work in nearby towns such as Hilsea (3 miles north), Wymering (4 miles north), Paulsgrove (5 miles north) and Cosham (4 miles north).
Around Southsea
Locally, jobs take us to houses, flats and workplaces close to The Festing pub, St Edmund's Catholic School and Mayville High School and the streets around them. Southsea’s nearest station is Fratton station, about 0.8 miles north of the centre. A little further out are St. Mary's Hospital (1 mile north) and Southsea Castle (1 mile south-west). Open spaces near Southsea include Milton Locks.
How we handle commercial air conditioning in Southsea
The right system depends on the building. Splits for small rooms, cassettes for open-plan ceilings, ducted for a hidden finish and VRF or VRV for many zones on one system. We set out the choices and the reasons behind our recommendation. Common call-outs are for F-gas leak checks and records that are overdue and systems over 12 kW due a TM44 inspection, on wall-mounted split systems, VRF systems and server and comms room cooling.
In a town like Southsea, commercial air conditioning typically means shops, offices, restaurants, surgeries and salons. Cassette units in the ceiling suit open spaces, while wall units or ducted systems suit smaller rooms.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

When to call us in Southsea
The GB phase-down is reducing HFC supply, so refrigerants like R410A are getting scarcer and dearer for top-ups. Servicing and repairing R410A systems is still allowed though it’s worth bearing in mind when planning ahead.
Most people get in touch after spotting something like this:
- Fit-outs and refurbishments that need new air conditioning
- R410A systems getting dearer to top up
- Installs that must fit around trading hours
Before any plant goes outside a building like St Margaret of Scotland, its trustees may need planning or heritage advice, and we work with whoever gives it.

What commercial air conditioning can’t fix
To be straight with you, some problems need a different answer:
- Boiler installation or repair
- Carrying out the TM44 inspection itself, which needs an accredited energy assessor
- Planning permission or landlord consent on your behalf
If in doubt, call us on 07833 053749 or email us and we will say what we think.
Where we work
- Ducted systems
- VRF systems

What affects the quote in Southsea
Your quote is based on your property. We take into account:
- Whether we need access equipment for high-level work
- How many units are involved
- The equipment or parts the job needs
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re not sure what’s needed, give us a ring on 07833 053749 or send an email for straight advice and a fixed price.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Any error code or flashing light on the display
- Where the outdoor unit is, or where you’d like it
- The rating plate or label on any existing unit
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Southsea questions
Will air conditioning in Southsea need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Southsea is a short walk from the Craneswater and Eastern Parade, Southsea Conservation Area. 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 is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the planning department at Portsmouth council, typically the authority for Southsea.
Can you do commercial air conditioning in Southsea?
Yes, Southsea is within the area we cover. To start, phone us on 07833 053749, or email if that’s easier with a few photos.
When will I hear back?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
How long will it take to install air conditioning in our building?
The work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. We confirm the timing after the survey, so ring 07833 053749 or fill in the contact form to arrange one.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
Do you offer commercial maintenance contracts?
Yes. A contract keeps the system serviced and any required leak checks on schedule, with records kept for each visit.
