Commercial air conditioning in Portswood
Commercial air conditioning comes with F-gas duties for the operator. Leak checks and records are required for systems from 5 tCO2e upwards. We carry out the checks, keep the records and tell you when the next one is due. If you’re dealing with commercial systems near the end of their life and changes of use that need a new layout, we can help.
Businesses near Portswood often have room for outdoor units on the ground at the back, which keeps them tidy and easy to reach.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Looking after it afterwards
How well a system lasts depends on use and care. Here’s what we suggest:
- Keep outdoor units clear of rubbish and stored goods
- Show staff how to use the controls properly
- Don’t wait for small faults to become breakdowns
Make a note of when a TM44 inspection will be due if the system is over 12 kW. When it comes round, we can get the system ready and carry out the recommendations.
Planned maintenance is the best way to keep a commercial system healthy. The schedule and cost are fixed up front.
What commercial work looks like in Portswood
Portswood lies within about 2 miles of the sea. Salt air shortens the life of unprotected outdoor coils, so coastal commercial systems need the right kit and regular servicing. The FSA’s food hygiene register shows about 225 restaurants, cafés and canteens, about 15 hotels, B&Bs and guest houses and about 43 schools and colleges within about 1.5 miles of central Portswood. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. About 43% of homes across Portswood and its surrounding area were built before 1919, according to VOA council tax data, and about 49% of households live in flats, according to the 2021 Census. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind.
If your office near St Denys station has a comms or server room, it needs cooling all year, not just in summer.

What else we do in Portswood
How the visit works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Photos of the existing unit and its label help with repairs and servicing near Portswood.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- The written quote is fixed and lists the plant, where it goes and the order of works.
- The work is planned around your opening hours, with out-of-hours or phased work where it helps.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- Finally it’s commissioned and handed over, with the refrigerant records and manuals for your files.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know if the units are on a roof, a high wall or in a locked area
- Have the make and model of any existing unit to hand
Getting a price
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.

Your questions about commercial air conditioning in Portswood
Is Portswood within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
Is the coast a problem for outdoor units in Portswood?
It can, as Portswood is within about 2 miles 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.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
What are the F-gas responsibilities for commercial air conditioning?
It depends on the system’s tCO2e. From 5 tCO2e, leak checks and records are needed, and from 500 tCO2e automatic leak detection is required.
Which commercial systems do you fit?
Everything from wall-mounted units for single rooms to VRF or VRV systems serving whole buildings. Cassettes and ducted units suit offices, shops and restaurants.
Can you do our TM44 air conditioning inspection?
No, the inspection needs an accredited energy assessor. We can prepare for the inspection and put right what it finds.
How much does commercial air conditioning cost?
A survey comes first, then a fixed-price quote. Factors include the number of areas, the system type, access and any out-of-hours or phased work.
What we’re called out for in Portswood
Ageing systems are a common reason for a call. Parts become harder to find and the system cannot keep up so replacement starts to make more sense than repair.
If any of these sounds familiar, it’s worth a diagnosis:
- Buildings that can’t close for the work
- Server rooms running too warm
- New tenancies needing cooling and heating
If you look after a church or hall such as Highfield Church, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.
What to look for in a quote
- Whether the price is fixed or an estimate
- What’s in the price and what isn’t
- Whether they hold F-Gas company certification, not just individual qualifications
How we price commercial air conditioning
The diagnosis comes before the price. The main factors are:
- Whether we need access equipment for high-level work
- How far the pipework has to run, and where
- What state the existing equipment is in
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will go through it with you.
Helping us quote
When you call or email, these details help:
- The rating plate or label on any existing unit
- Where the property is and what kind of building it is
- A short video of any fault, such as a noise or a flashing light
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To start, call 07833 053749 or use the quote form.
