Commercial air conditioning in Portchester, done properly
Server rooms and comms rooms need cooling that keeps going. We look at the heat load and how the room is used, and can discuss backup units so one failure does not take everything down. The work covers ceiling cassettes, VRF systems and multi-split systems, and the jobs we see most are planning ahead for the HFC phase-down and installs that must fit around trading hours.
For a business near Portchester, there’s normally space for plant at the rear, which keeps them tidy and easy to reach.

Your questions about commercial air conditioning in Portchester
Is air conditioning in Portchester permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Central Portchester sits inside the Portchester (Castle Street) Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Fareham council, which is typically the planning authority for Portchester.
Does sea air affect air conditioning in Portchester?
It can. Portchester is within about 1 mile of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.
Can you look after our air conditioning after it’s installed?
We do. With a contract, servicing and F-gas checks happen on time and every visit is recorded.
How often is a TM44 inspection needed?
At over 12 kW, inspections are due at least every 5 years. An accredited energy assessor does the inspection, and we can carry out the recommended work.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Report noises, leaks and faults early
- Avoid units heating and cooling the same space
- Plan regular servicing with a contract
For systems over 12 kW, keep track of the 5-yearly TM44 inspection. When it comes round, we can get the system ready and carry out the recommendations.
Good records make inspections and audits easier. For systems at or over 5 tCO2e, they’re required.

Owner checks or an engineer?
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
What commercial work looks like in Portchester

How the visit works
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, and that takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Seeing the property in photos first helps us plan the trip to Portchester.
- We survey the site and talk through how each area is used.
- You get our recommendation and a fixed price.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
Before we arrive
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Clear the space around the indoor unit, or where it will go
- Unlock any gate, garage or side passage we need
How to get a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.
