Prime Air Conditioning

Commercial and industrial air conditioning in Hampshire: For places that can't stop when it gets hot.

From one cassette over a shop floor to a row of condensers on a factory roof: installed around your opening hours, maintained on a schedule, and with the F-Gas paperwork kept straight.

Sized for the heat the building makes

People, computers, machinery and glass all add heat. Commercial systems are sized from that load, not from the floor area, and placed where they can be maintained safely.

Offices and meeting rooms

Ceiling cassettes or wall units zoned so the meeting room and the open-plan floor are set separately. Quiet enough that nobody notices it on a call.

Server and comms rooms

Units rated to cool all year round, including January, and often fitted in pairs, each sized to cool the room on its own, so one can fail without the room overheating.

Industrial units and workshops

High roofs, big doors and machinery make their own weather. Cooling the areas where people work can make more sense than cooling the whole volume, and dust clogs filters fast, so workshop units usually need cleaning every 3 to 6 months. Plant goes where it's safe to reach, with the pipework protected from forklifts and weather.

Planned maintenance, so fewer breakdown calls

A planned schedule spots worn fans, weak capacitors and slow leaks on a quiet Tuesday, not in the middle of a heatwave. Every visit leaves a record you can show an auditor, a landlord or an insurer.

Asset list
Every indoor and outdoor unit on the site, with make, model, refrigerant and location.
Visits
Every 3, 6 or 12 months depending on how hard the system works and what the manufacturer asks for.
Each visit
Filters, coils and drains cleaned; refrigerant, electrics and controls checked; air temperatures measured.
F-Gas
Leak checks at the intervals the rules set for your system, logged and kept.
Records
A service report per visit, so the history of each unit is in one place.

What the paperwork looks like

Every maintained site gets an asset register like this, updated at each visit. The rows below are a cut-down example, not a real customer - the full register also lists the make and model of every indoor and outdoor unit.

Example only. Each row is one refrigerant system - indoor and outdoor units and the pipework between them - so the charge is the whole system's. CO2 equivalent = refrigerant charge x its global warming potential (R32 675, R410A 2088). At over 12 kW in total, this example site would also need a TM44 inspection. For systems that need leak checks, the F-Gas rules require the records to be kept for at least five years.

F-Gas: the part most sites forget

If you operate air conditioning, the F-Gas rules make you responsible for it: leaks must be repaired, only a certified engineer may work on the refrigerant, and larger systems must be leak-checked at set intervals with records kept.

  • 5 tonnes CO2 equivalent or more - a leak check at least every 12 months. That is roughly 2.4 kg of R410A or 7.4 kg of R32.
  • 50 tonnes or more - at least every 6 months.
  • Separately from F-Gas, if the air conditioning you control in a building adds up to more than 12 kW, it needs an energy inspection by an accredited assessor (TM44) at least every five years.

We'll tell you which of your systems the rules apply to, put the checks on the schedule, and keep the records ready if anyone asks for them.

Fitting a building that has to stay open

Most commercial installs happen around people still working. This is how we keep it that way.

Before day one
A site survey, a written quote with the model numbers, and a plan for each day. Risk assessments and method statements on request.
Zone by zone
We work through the building an area at a time, so most of it stays usable; the noisy work can be booked for evenings or weekends.
Comms rooms
A changeover is planned so the room is never left without cooling.
Old equipment
Decommissioned properly: the refrigerant recovered by an F-Gas certified engineer and disposed of with the paperwork.
Leased premises
The unit positions, drawings and noise figures your landlord will ask for before giving consent.
Every day
Dust sheets down, a tidy at the end of each day, and the site left as we found it.

What helps us quote a commercial job

None of it is essential to get started - but the more of it you can send, the faster and firmer the price.

  • Site address and when we can get in: opening hours, parking, keyholders.
  • Rooms or zones to cover, with rough sizes and how many people use them.
  • Where plant can go - roof, rear wall or yard - and how to reach it.
  • Existing equipment: make, model and age of any units already on site.
  • Drawings or photos, if you have them - phone photos are fine. We'll tell you how to send them when we reply.
  • Working hours we need to stay inside, so the work fits around your business.

Business questions

Our old units use R22. Can they be re-gassed?

Not with R22. Using it to service a system has been banned in the UK since 2015, so a leaking R22 system can't legally be topped up. Some systems can be converted to a replacement refrigerant, but at that age a new system is usually the better option - we'll quote for one, and reuse pipe routes where it's safe to.

Do our systems need a TM44 inspection?

If the air conditioning units you control in a building add up to more than 12 kW of cooling, they need an energy inspection by an accredited assessor at least every five years. We'll tell you whether yours do.

Do we need F-Gas leak checks?

Only for systems holding 5 tonnes CO2 equivalent or more - roughly 2.4 kg of R410A or 7.4 kg of R32. A small R32 wall unit is well under it, but a larger R410A cassette, multi-split or rooftop system often isn't. Our asset register works it out system by system.

We walk the site, list every unit, check where it stands on F-Gas, and price the work or a maintenance plan.
