These are four independent proportions of the same panel, not stages of a funnel. | Layer | Question | Cleared the bar | Strength | Of those who passed | | --- | --- | --- | --- | --- | | 1. Clarity | Do they understand what you do? | 15/15 | 99% | 14 without hesitation, 1 with reservations | | 2. Relevance | Can they tell what it solves, and who it's for? | 15/15 | 93% | 10 without hesitation, 5 with reservations | | 3. Value | Do they actually want it? | 4/15 | 37% | all with reservations | | 4. Differentiation | Is there a reason to pick you over the alternatives? | 4/15 | 37% | all with reservations | **Brand alignment** (a side metric, not one of the four layers) — 13/15, 70% strength (all with reservations). Does the page read like the company you actually are? **Fix first: Value.** Earliest failing layer, walking the sequence in order — not simply the lowest score. --- ## 02 · What to change, layer by layer Ordered worst-first. Specific edits, not a restatement of the score. ### Value **Add hard numbers to the Meridian House story.** The Meridian House quote says the building 'is as future-proof as it can be' but names no kW, no energy saving, no programme or cost figure. Rewrite it as a short case panel with the specifics a specifier would check: building type and floor area, the actual product (City Multi / HVRF), the measured or designed improvement, and the compliance target hit. Readers said testimonials without hard data will not stand in for a project case study, and the page currently has no numbers anywhere. *effort medium · impact high · tested against Specifics beat superlatives* **Give the compliance hook a reason to contact now.** Nothing on the page connects to where the specifier actually is: mid-tender with Part L or BREEAM requirements to satisfy. Those drivers only appear buried in the testimonial quotes at the very bottom. Pull them into the top of the page and into the Contact block — name Part L and BREEAM explicitly and say what a Sales Engineer will bring to a live tender — so engagement does not depend on the reader supplying their own reason. *effort medium · impact high · tested against Problem before solution* **State what specifier support saves in time or turnaround.** 'We can also provide you with BIM files and comprehensive specification documents to help you with your tender package' is the one line readers said had real practical value, yet it promises nothing measurable. Attach the outcome and the commitment: which systems are covered (VRF, chiller, HVRF), which formats, and how quickly a request is turned around. Without that, BIM files and CPD read as table stakes every manufacturer offers. *effort low · impact high · tested against Tie the feature to the outcome* ### Differentiation **Publish the audit standard behind DQP installations.** 'DQP Partner level installations are routinely independently audited to ensure high standards are maintained' is the strongest claim on the page and the least verifiable. Say who audits, against what standard, how often, and what proportion of installations pass — then link the evidence next to the claim. Readers said this is the detail that would justify recommending a switch of supplier, and without it the sentence is a promise a rival could copy verbatim. *effort medium · impact high · tested against Proof next to the claim* **Spell out the seven-year warranty terms and conditions.** 'extended warranties can be offered of up to 7 years' hedges twice — 'can be offered' and 'up to' — so a specifier cannot tell what their client actually gets. Replace with the real terms: standard years, what BSP or DQP installation adds, what is covered (parts, labour, compressor), and the registration condition. Readers weighing this against competing manufacturers could not resolve the comparison from the current wording. *effort low · impact high · tested against Answer the live objection* **Replace 'best product for your project' with a specific reason.** 'We can help you specify the best product for your project' and 'design the right solution for your project' are claims any HVAC manufacturer could paste onto their own page unchanged. Swap them for the things only this page can say: local Sales Engineers with named coverage, a tiered and audited partner network, and warranty length. Lead the benefit tiles with those rather than with generic help. *effort low · impact medium · tested against Give a reason to choose you* ### Clarity **Name real project types in the sector tiles.** The sector grid gives only single-word labels — 'Retail', 'Office', 'Leisure' — which readers found too generic to tell them whether their project is covered. Add a few words per tile naming typical applications and systems (for example, mixed-use office fit-out with VRF, or hotel refurbishment with HVRF) so a specifier mid-tender can self-select immediately. *effort medium · impact medium · tested against Concrete over abstract* ### Brand alignment (side metric) **Fix the 'Ask ME' hero line and capitalisation.** 'Ask ME about specifier support' was read as a broken template variable or unfinished placeholder rather than a deliberate play on the Mitsubishi Electric initials. Either spell it out so the pun lands ('Ask Mitsubishi Electric about specifier support') or set ME visually distinct with a short explanatory line, so the first thing a specifier sees does not look like a publishing error. *effort low · impact medium · tested against Plain language* --- ## 03 · What is working ### The header and opening lines make the specifier audience unmistakable Nine respondents said the page's header, tagline and benefit tiles made the target audience — architects, specifiers and B2B design professionals — immediately obvious, along with the scope of specifier support on offer. Several noted the page reads clearly as a support hub carved out for specifiers rather than a standalone product pitch, with the audience switch signalled by the header and sector grid. > Ask ME about specifier support > > — Specifying Engineer - HVAC, Engineering, 11-50 > It's not really a "product" in its own right, it's a manufacturer's sales and support hub bolted onto their VRF/City Multi and Mr Slim ranges. > > — Senior HVAC Specifier, Engineering, 11-50 > They clearly sell mainly to installers and end-users normally, and this page is a deliberate offshoot carved out for specifiers/architects/consulting engineers — the "Ask ME about specifier support" header and sector grid (Retail, Office, Healthcare, Housing Developers) make that audience switch explicit > > — Director of Specifications, Building Services, 201-500 > Honestly it wasn't hard to pin down what they make — that part was clear from the product names and the 'cool, heat, ventilate and control' line. > > — HVAC Specifier, Construction, 1-10 ### The DQP installer audits and seven-year extended warranty are the differentiators… Five respondents pointed to the tiered installer partner system, DQP partner auditing and the extended warranty of up to seven years as concrete, repeatable differentiators. One respondent noted that named firms with regulatory drivers carried more weight than generic promises. > up to 7 years > > — Specifying Engineer - HVAC, Engineering, 11-50 > The thing that would actually tip a shortlist decision is the DQP/BSP partner tier with the "extended warranties can be offered of up to 7 years" line, plus the note that "DQP Partner level installations are routinely independently audited" > > — Senior HVAC Specifier, Engineering, 11-50 > The quotes from Lamorbey Associates and Hilson Moran about BREEAM and Part L compliance are the only bit with any real weight - named firms and a concrete regulatory driver > > — Senior HVAC Specifier, Engineering, 11-50 > Diamond Quality Partners (DQP), Business Solutions Partners (BSP) and Accredited Installers (AI)" with "extended warranties can be offered of up to 7 years" and DQP installs being "routinely independently audited. > > — Specifying Engineer - HVAC, Architecture, 51-200 > with our BSP and DQP Partners, extended warranties can be offered of up to 7 years" plus the note that DQP installs are "routinely independently audited." That's an actual differentiator I could put in front of a client or contracts team, versus a competitor's standard 1-2 year warranty > > — Lead Specifier, Architecture, 51-200 > The one concrete thing that would tip it my way is the "extended warranties can be offered of up to 7 years" through DQP/BSP partners, plus the line that "DQP Partner level installations are routinely independently audited" > > — HVAC Specifier, Construction, 1-10 --- ## 04 · What the personas said ### The hero line and 'Ask ME' capitalisation read as an unfinished template placeholder Three respondents flagged the hero/header copy as broken — describing it as a template variable failure or unfinished placeholder rather than a deliberate tagline — with one specifically calling out the capitalisation error in 'Ask ME'. This undercut the otherwise clear framing of the page. > the hero line itself, "Ask ME about specifier support," which reads like a typo or a broken template variable rather than a deliberate tagline, and it made me pause for a second wondering if a merge field had failed. > > — Lead Specifier, Architecture, 51-200 > If anything got in the way it was 'Ask ME about specifier support' at the very top, which reads like a broken placeholder tag rather than actual copy, and that sloppiness is what I'd flag as odd on the page. > > — HVAC Specifier, Construction, 1-10 > the phrase "Ask ME about specifier support" was the odd one, a stray capitalisation that reads like a template placeholder someone forgot to fill in with a name > > — Lead Specifier, Building Services, 201-500 ### The generic sector tiles do not connect to mid-tender compliance needs Three respondents said the sector tiles were too generic to be useful, and that without actual project types stated upfront the page failed to address where they actually are — mid-tender, with compliance requirements. One noted the page targets specifiers clearly but still lacks competitive differentiation. > it's clear on WHO but vague on WHY ME OVER A COMPETITOR—there's no comparative data, just reassurance copy. > > — Lead Specifier, Architecture, 51-200 > I'd need to see my actual project type named upfront — e.g. 'retrofitting a listed office building' or 'small residential new-build' — rather than a generic sector tile grid > > — HVAC Specifier, Construction, 1-10 > I'd need something that acknowledges I'm mid-tender with a specific compliance target — e.g. "upload your Part L calc and we'll flag the compliant City Multi configuration" — rather than generic sector tiles > > — Lead Specifier, Building Services, 201-500 ### There are no named projects, numbers or hard data anywhere on the page Five respondents said the page carries no named projects, cost or programme details, lead times or efficiency figures. Two explicitly said testimonials would not substitute for a project case study with hard data. > There's nothing here with a number I can hold them to (no lead times, no cost comparison, no efficiency % with a source), so it's not worth a meeting on its own > > — HVAC Specifier, Construction, 1-10 > no named projects with numbers, just quotes > > — Specifying Engineer - HVAC, Engineering, 11-50 > I'd need a named project near my own building type with hard figures - kW capacity, SFP, actual BREEAM credits achieved - not a testimonial paragraph > > — Senior HVAC Specifier, Engineering, 11-50 > it would need a named project like mine (small practice, mixed-use) with a cost or programme number attached, not just generic sector tiles. > > — Director of Specifications, Construction, 1-10 ### The warranty and audit claims are unverifiable as written, so they do not yet separate… Three respondents said the differentiators only hold if the underlying detail is supplied — the audit standard, DQP installation pass rates, and clear warranty terms — and named Daikin and Toshiba as the comparison they could not resolve. One respondent noted this is what would be needed to justify switching suppliers. > A verified, sourced number on the DQP audit process — pass rate, audit frequency, who conducts it — because that's the one claim on the page with enough specificity to actually change a recommendation > > — Lead Specifier, Building Services, 201-500 > to choose Mitsubishi over them I'd need the audit process spelled out — who audits, how often, against what standard — not just the claim that it happens. > > — HVAC Specifier, Construction, 1-10 ### Engagement is conditional on a live project, not on the page itself Three respondents said they would only take a meeting if they had a live tender or project with a specific hook — Part L or BREEAM compliance, or a need for VRF and chiller BIM files. The page did not create a reason to engage on its own. > I'd only take one if I already had a live project where the Part L or BREEAM angle mattered, like the Hilson Moran or Lamorbey Associates jobs mentioned. Otherwise it's a "keep the brochure and call when I need it" situation > > — Senior HVAC Specifier, Engineering, 11-50 > The one outcome worth my time is a live tender where I need VRF or chiller BIM files fast and a CPD session slotted into a lunch hour > > — HVAC Specifier, Construction, 1-10 ### CPD, BIM files and portfolio are read as table stakes, though BIM and spec documents do… One respondent dismissed CPD, BIM files and the portfolio as table stakes offering no differentiating value, while another said BIM files and spec documents genuinely save time on tender packages. The same assets were read as both baseline expectation and practical value. > CPD seminars, "comprehensive HVAC portfolio," BIM files — is table stakes any manufacturer offers, so it wouldn't differentiate against a similar shortlisted option. > > — HVAC Specifier, Construction, 1-10 --- ## 05 · The hardest read An adversarial pass over the findings. Every claim below was checked against the panel's own answers; unsupported ones were dropped. - **The page's only real differentiators collapse the moment anyone tries to verify them, so the strongest asset on the page doubles as its biggest credibility liability.** *(high)* Five respondents named DQP audits and the seven-year warranty as concrete differentiators, but three said those same claims only hold if the audit standard, installation pass rates and warranty terms are supplied, and could not resolve the page against Daikin and Toshiba. The page asks to be believed on exactly the points it refuses to evidence. - **Clarity is the page's ceiling, not its foundation — respondents understood who it was for and still had no reason to act.** *(high)* Nine respondents found the specifier audience unmistakable, yet three said they would only engage given a live tender with a Part L, BREEAM or BIM hook, and the page created no reason to engage on its own. Being legible is not the same as being persuasive, and this page stops at legible. - **An evidence vacuum sits at the centre of the page and every other weakness feeds off it.** *(high)* Five respondents found no named projects, costs, programme details, lead times or efficiency figures, and two said testimonials would not substitute for a case study with hard data. That same absence is what makes the warranty and audit claims unverifiable and the sector tiles generic. One fix would resolve three failures; the page makes none of them. - **The page speaks to a job title rather than a moment, so it lands nowhere near the point of decision.** *(high)* Three respondents said the sector tiles were too generic and failed to address where they actually are — mid-tender with compliance requirements — while three others said engagement depends on a live project with a specific compliance or BIM hook. The page identifies its audience correctly and then misses their situation entirely. - **Nothing on the page justifies a supplier switch, which is the only decision that matters here.** *(high)* Three respondents said the differentiators only justify switching if the underlying detail is supplied and named Daikin and Toshiba as an unresolved comparison, while another said the page lacks competitive differentiation despite clear targeting. Five respondents found no hard data with which to build that case. - **The support assets are worth nothing until the page tells readers which tender problem they solve.** *(medium)* One respondent dismissed CPD, BIM files and the portfolio as table stakes with no differentiating value while another said BIM files and spec documents genuinely save time on tender packages. The identical assets read as both baseline and useful, which means the page is not doing the work of framing them; and three respondents said generic tiles fail to connect to mid-tender compliance needs. --- ## 06 · Who answered | # | Role | Industry | Company size | | --- | --- | --- | --- | | 1 | Specifying Engineer - HVAC | Engineering | 11-50 | | 2 | Lead Specifier | Architecture | 51-200 | | 3 | Director of Specifications | Building Services | 201-500 | | 4 | HVAC Specifier | Construction | 1-10 | | 5 | Senior HVAC Specifier | Engineering | 11-50 | | 6 | Specifying Engineer - HVAC | Architecture | 51-200 | | 7 | Lead Specifier | Building Services | 201-500 | | 8 | Director of Specifications | Construction | 1-10 | | 9 | HVAC Specifier | Engineering | 11-50 | | 10 | Senior HVAC Specifier | Architecture | 51-200 | | 11 | Specifying Engineer - HVAC | Building Services | 201-500 | | 12 | Lead Specifier | Construction | 1-10 | | 13 | Director of Specifications | Engineering | 11-50 | | 14 | HVAC Specifier | Architecture | 51-200 | | 15 | Senior HVAC Specifier | Building Services | 201-500 | --- ## 07 · Before you act on this The methodology is real, and the critique is directional. What a simulated persona cannot have is a live budget, a renewal coming up, or a boss asking about this quarter. **Validate anything you're betting on with real ICPs who are actually in-market.** Being wrong is more expensive than you think.
