How the visit works
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. The visit takes anything from a day or two for a small office to several weeks of phased work on a large building. Town-centre streets in a place like Portsmouth can be tight, so tell us the parking options.
- We survey the site and talk through how each area is used.
- We recommend a system and send a fixed-price quote.
- The programme is agreed, including any out-of-hours or phased work.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
Preparing for the visit
- Let us know where the consumer unit is
- Arrange for someone to be there to let us in
- Mention any managing agent or landlord rules we need to follow
Ask for a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price before any work starts.

About our commercial air conditioning in Portsmouth
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 older systems that can’t keep up and buildings that can’t close for the work, on server and comms room cooling, VRF systems and wall-mounted split systems.
A comms room in Portsmouth needs cooling every day of the year, so a second unit for back-up is often worth it.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

What air conditioning won’t do
A few issues sit outside what this work can do:

- Fire strategy sign-off
- Major builder’s work such as new openings in structural walls

What owners can safely do
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and ring us on 07833 053749 or drop us a line.
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 helps us diagnose quickly, and a photo or a short video of the display is even better.
Commercial air conditioning around Portsmouth
At about 1 mile from the coast, Portsmouth is close enough for sea air to matter. Salt air shortens the life of unprotected outdoor coils, so coastal commercial systems need the right kit and regular servicing. Food Standards Agency records list about 262 restaurants, cafés and canteens, about 16 hotels, B&Bs and guest houses and about 48 schools and colleges in and around Portsmouth, up to about a mile and a half out. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. VOA council tax data put about 57% of homes in the Portsmouth area before 1919, and the last census (2021) found about 53% of households in terraced houses. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care.
Schools such as Manor Infant School usually have the work done in the holidays, when classrooms are empty. Churches and halls such as St Wilfrid are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.

Portsmouth: your questions answered
Does sea air affect air conditioning in Portsmouth?
It can, as Portsmouth is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Can I fit air conditioning in Portsmouth without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Portsmouth is a short walk from the St Mary's Churchyard, Fratton 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, usually the authority for Portsmouth.
What kind of air conditioning can you install in a business?
From one wall-mounted unit to VRF across several floors. Cassettes and ducted units are common choices for open-plan and visible spaces.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
When is a TM44 inspection required?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. An accredited energy assessor does the inspection, and we can carry out the recommended work.
Do you work in Portsmouth?
Yes. Portsmouth is part of the area we cover, within the South East and London area we cover. We are based in East Grinstead, West Sussex.
Which brands do you work with?
We install and work on the leading makes, 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.

“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.”
