Commercial air conditioning in Cosham, done properly
Once a system is in, it needs looking after. A maintenance contract keeps servicing and leak checks on schedule, with the records kept up to date, at a price fixed with your quote. Our 24/7 emergency line is there if something goes wrong. Typical jobs include systems over 12 kW due a TM44 inspection and workspaces that overheat on warm days, on ducted systems, multi-split systems and wall-mounted split systems.
For a business in or near Cosham, an air-to-air system can heat and cool, which can replace old heaters in shops and offices.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Looking after it afterwards
Once we’ve finished, these simple steps help:
- Plan replacements before old systems fail
- File every leak check and service record in one place
- Show staff how to use the controls properly
Once the system is commissioned, we hand over the records, the controls and the manufacturer documents. They’ll be needed for servicing, leak checks and TM44 inspections.
Plan replacements before old systems fail, particularly where they use R410A.
Cosham: your questions answered
Do you cover smaller places like Cosham?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is the coast a problem for outdoor units in Cosham?
It can, as Cosham is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
What does the operator have to do under the F-gas rules?
It depends on the system’s tCO2e. Systems at or above 5 tCO2e need leak checks and records with automatic leak detection at 500 tCO2e and above.
Do you offer commercial maintenance contracts?
Yes, maintenance contracts cover servicing, F-gas leak checks and records. The visits and price are fixed with your quote.
How long will it take to install air conditioning in our building?
An installation takes a few days for a small shop or office, longer for VRF across several floors. We confirm the timing after the survey, and you can phone us on 07833 053749 to book it.
Business air conditioning in Cosham
At about 1 mile from the coast, Cosham is close enough for sea air to matter. Commercial condensers near the coast should be checked for corrosion on every maintenance visit. The FSA’s food hygiene register shows about 78 cafés, restaurants and staff canteens, about 6 hotels and guest houses and about 18 schools and colleges within roughly a mile and a half of the centre of Cosham. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. In the mile around Cosham’s centre, 2 conservation areas have been designated. About 5 listed entries lie within half a mile of central Cosham, Wymering Manor (grade II*) among them. That matters for air conditioning: permitted development does not apply within the grounds of a listed building, in a conservation area the outdoor unit cannot go on a wall or roof facing a road, and a unit used only for cooling is not covered at all, so we check with Portsmouth council, normally the planning authority here where necessary.
Churches and halls such as Church of St Philip 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. For a school like Court Lane Junior Academy, air conditioning work is best done out of term.

How we price commercial air conditioning
The survey or diagnosis tells us what the work involves. The main factors are:
- How easy the units are to reach
- The size of the job
- Whether it’s a simple split or a larger system
A single unit or a whole estate, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before we start, and the quote sets out the VAT.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- The make and model of the system, from the label
- Where the property is and what kind of building it is
- A photo of the consumer unit with the cover closed
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.

What happens on the day
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. In a place like Cosham, parking is rarely an issue, but tell us about gates and access to the back of the property.
- You tell us about the building and what’s needed.
- A site survey confirms the heat load, the layout and the access.
- The options, cost and timing are set out in a fixed-price quote.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
Getting ready for the visit
- Mention any roof access, ladders or high-level work
- Tell us about any building rules, permits or sign-in
- Give us access to the outside wall, roof or yard where the outdoor unit sits
Getting a quote
Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

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.”
