Commercial air conditioning around Longstock
Longstock’s centre is no more than about a third of a mile from the Longstock Conservation Area. There are 2 conservation areas within a mile of the centre of Longstock. Listed buildings are part of the picture here: about 34 within half a mile of the centre, such as Sindle Cottage (grade II). Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, the local planning authority (normally Test Valley council) has the final say on what’s allowed. Longstock is about 65 miles from central London, well within the area we cover from our base in East Grinstead.

Commercial air conditioning in Longstock
Heating, cooling and fresh air often go together. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside, so the building works as a whole. The work covers VRF systems, wall-mounted split systems and multi-split systems, and common reasons people get in touch are systems that need out-of-hours or phased installation and IT rooms that need resilient cooling.
Around Longstock, there’s usually space for outdoor plant away from the road.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What happens on the day
Each visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, test what we’ve done and talk you through it. The visit itself takes anything from a day or two for a small office to several weeks of phased work on a large building. Somewhere like Longstock, it helps to know about lanes, gates and where to park.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- The written quote is fixed and lists the plant, where it goes and the order of works.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
Preparing for the visit
- Name a contact who can meet us at the agreed time
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about parking and loading

Rented and managed buildings
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side, and the paperwork can go to both.
We also work for facilities teams in offices, schools and public buildings across Hampshire. Larger buildings can be done in stages to keep disruption down.
How the job changes from property to property
VRF and VRV systems
VRF (variable refrigerant flow), also called VRV, connects many indoor units to shared outdoor units. Each zone can be controlled separately, which suits offices, hotels and multi-room buildings.
Shops and restaurants
For a discreet finish, ducted systems and cassettes are popular.
Your questions about commercial air conditioning in Longstock
Is Longstock in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Longstock is part of that. Get in touch with the details and we reply the same working day.
Will you come out to Longstock?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
How much does commercial air conditioning cost?
We price commercial work after visiting the site. That lets us size the system properly and plan the work and you get a fixed price.
How often is a TM44 inspection needed?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. GOV.UK has guidance on how it works, and we can help you prepare.
Is planning permission needed for the outdoor unit?
Not always. On a house, air-to-water heat pumps and, since 2025, air-to-air systems that heat as well as cool can be permitted development if they meet the conditions. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it usually comes up, and we tell you at the survey. This is general information, not legal advice.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Why it’s worth doing now in Longstock
A system that cannot cope on the hottest days affects everyone in the building. Planning a replacement or upgrade before the summer is easier than reacting in a heatwave. A dirty or faulty system works harder and costs more to run.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re unsure, phone us on 07833 053749 or email us and we will give you an honest view and a fixed price.
