It is the room volume, the glazing and which way it faces, the insulation, how many people are in the space and when, the heat given off by equipment, and how often doors open. Get that wrong on the low side and the system runs continuously and never reaches setpoint; get it wrong on the high side and it short-cycles, dehumidifies badly and costs more than it needed to. We survey free of charge across Welshpool, Shrewsbury, Oswestry, Newtown and the surrounding mid-Wales and Shropshire area, and return a free written quotation the same or the following working day depending on the size of the job. Because we are not tied to a single manufacturer's accreditation scheme, the design is driven by the building rather than by whichever brand we are signed up to. That applies to indoor unit type, outdoor unit siting, pipe routing, condensate strategy and electrical supply. ### Who this is for, and when you need it Businesses fitting out a new spaceCooling planned alongside the fit-out, with routes and plant positions agreed before ceilings and walls close up. Landlords and facilities teamsSpecifications and options across a portfolio, with RAMS on request and consistent kit choices between sites. Architects, builders and main contractorsA contractor who will attend the site, mark up routes and give a specification your programme can actually be built around. Server and comms roomsEquipment heat load calculated properly, with resilience and continuous running designed in from the start. Homeowners planning a projectExtensions, loft conversions and garden rooms designed around the actual load and the routes available in the building. Anyone holding a quote they do not trustA second survey and an independent specification, so you can see whether what you were quoted was sized on evidence or on a guess. The cost of leaving it ## What a bad specification costs later Almost every system we are called to that 'never really worked' was decided before anyone measured anything. Someone picked a unit off a price list, someone else agreed a position because it was the easiest place to drill, and the building was never assessed at all. Undersized systems run permanently at full output and still leave the room warm on the days you actually needed them. Oversized systems cycle on and off, leave the air clammy, wear their components out faster and cost more to buy. Badly sited outdoor units recirculate their own hot air, lose efficiency and land noise on the wrong window. None of that can be fixed afterwards without ripping work out. It is decided at survey — which is exactly why the survey is free and why we would rather spend an hour in the building than quote from a floor plan. ### Undersized capacity The system runs flat out on the hottest afternoon and never reaches setpoint — the day you bought it for. ### Oversized plant Short-cycling, poor dehumidification, faster component wear and money spent on capacity you never use. ### Bad outdoor unit siting Enclosed corners recirculate hot air and cut efficiency, and noise lands on a neighbour's window instead of a blank wall. ### Pipe and condensate routes decided on the day Runs that could have been hidden end up surface-mounted, and drainage that should fall naturally ends up on a pump. ### Electrical supply not checked Finding out the supply will not carry the plant after the kit has been ordered delays the whole job. ### No phasing plan Works that were never programmed around trading hours cost you the trade the system was supposed to protect. ### Common mistakes we are called out to fix - Sizing from a floor area rule of thumb instead of an actual heat load. - Quoting from a plan without ever attending the building. - Ignoring equipment and occupancy load in offices and comms rooms. - Choosing indoor unit types before checking ceiling voids and structure. - Leaving outdoor unit positions to be decided by the installer on day one. - Comparing quotes on price alone when they are not specifying the same system. Our process ## A step-by-step system, so you always know what happens next - 01 ### Free site attendance We come to the building, walk the spaces and talk through how they are actually used — not how a drawing says they are used. - 02 ### Heat load assessment Room volumes, glazing and orientation, insulation, occupancy and equipment load are measured and counted so capacity is based on evidence. - 03 ### Unit selection and layout Wall-mounted, cassette, ducted, multi-split or VRV/VRF chosen against the ceiling, structure and layout, with indoor positions marked up. - 04 ### Pipe routing, drainage and plant positions Refrigerant runs, condensate falls and outdoor unit locations planned for airflow, noise and access — before anyone drills anything. - 05 ### Electrical and access checks Supply capacity, isolation, working at height and site access confirmed, with RAMS issued on request for inductions. - 06 ### Free written quotation A specification you can hold a contractor to: what goes where, what the kit is, what the works involve and what it costs — same or next working day. - 07 ### Programme agreed before we start Phasing, out-of-hours working and access agreed in advance so the installation fits around your trading hours. What you get ## Specific outcomes, not vague promises ### Free survey and free quotation No charge to have the building assessed and no charge for the written specification that comes back. ### Sized on evidence Heat load assessed properly, so the system holds temperature rather than chasing it. ### Multi-brand specification No accreditation scheme dictating the kit. We specify what suits the building, the budget and the running costs. ### Quotes you can compare A written spec makes it obvious whether two quotes are for the same system or two very different ones. ### Same or next working day turnaround Quotations come back quickly, sized to the job, so your programme is not waiting on us. ### Installation-ready detail Routes, positions, drainage and supply resolved at design stage, which is what keeps installations tidy and on programme. ### RAMS on request Risk assessments and method statements provided for site inductions, facilities teams and main contractors. ### One contractor from design to aftercare The people who design it install it, commission it and maintain it — so nobody can blame the last party involved. In detail ## How the design decisions are actually made A specification is a series of trade-offs. Here is what sits behind each of them, so you can read a quote and understand what you are being offered. ### Calculating heat load Load comes from the fabric (glazing, orientation, insulation, roof), the occupancy (how many people, for how long) and the equipment (IT, kitchen, machinery, lighting). Each is counted rather than estimated as a lump. The output is a capacity figure per space, which is what unit selection is then built on. Without it, everything downstream is a guess. ### Choosing the indoor unit type Wall-mounted units are quick, cost-effective and ideal for single rooms. Cassettes distribute air far more evenly across open-plan floors but need ceiling void depth and a condensate route. Ducted units hide everything except the grilles, which suits design-sensitive and listed interiors but is the most involved to install. The building usually makes this decision. Void depth, structure, ceiling type and how the space is used matter more than preference. ### Single split, multi-split or VRV/VRF One outdoor unit per indoor unit is simplest. Multi-splits serve several indoor units from one condenser and save external space, which often decides it on high-street and terraced properties. VRV/VRF serves many zones from modular plant, varies flow to demand and scales for future floors. Line lengths and level differences affect performance on multi-splits and VRF, which is survey work — not something to resolve on installation day. ### Siting the outdoor units Condensers need free airflow, service access, a solid mounting and a position where noise does not land somewhere sensitive. Enclosed corners that recirculate hot air are the most common avoidable mistake we find. Roof platforms, wall brackets and ground frames each carry their own access, weight and noise considerations, and are chosen at survey. ### Pipe routing and condensate Refrigerant routes are planned to be as short, as direct and as concealed as the building allows. Condensate is best run on natural fall; lift pumps are used where the layout leaves no alternative, not as a default. Deciding this at survey is why installations end up tidy. Deciding it on the day is why some do not. ### Heating, efficiency and running cost Nearly everything we specify is a heat pump, delivering several units of heat per unit of electricity in reverse cycle. For buildings across mid-Wales and Shropshire with poor or expensive heating, that winter performance is often what justifies the project. Inverter-driven plant, properly sized, uses noticeably less energy than oversized fixed-speed equipment — which is where good design pays for itself. Questions ## System design & site surveys — your questions answered Is the survey really free?Yes. Site surveys and written quotations are free, and there is no obligation to proceed. How quickly will I get the quotation?The same working day or the following one for most jobs. Larger multi-zone projects can take slightly longer because the design work behind them is bigger. How long does the survey take on site?Usually under an hour for a straightforward property. Larger commercial buildings take longer because there is more to measure and more access to check. Will you tell me if I do not need what I asked for?Yes. If a smaller system, a different unit type or a repair to what you already have is the better answer, that is what the survey will say. Can you review a quote I have already been given?We are happy to survey and specify independently so you can compare like for like. A written specification makes it obvious whether two quotes cover the same system. Do you provide RAMS and paperwork for contractors?Yes — risk assessments and method statements are issued on request for site inductions, along with our insurance details and F-Gas credentials. Do you design around a building programme?Yes. Phasing, access and out-of-hours working are agreed before we start, and we will coordinate with your main contractor where there is one. Do you cover my area?We survey across Welshpool, Shrewsbury, Oswestry, Newtown, Llanidloes, Llandrindod Wells, Aberystwyth and the surrounding mid-Wales and Shropshire villages.
