HVAC Website Grader: Free Instant Site Check
Free · no signup · runs instantly. Updated 2026-08-13
This HVAC website grader tests ten on-page fundamentals against your live site and returns a 0–100 score with the specific fixes. It fetches your page the way a crawler does — no signup, no report email, results on screen in seconds.
What the grader checks
Each check runs against your page's actual HTML at scan time:
| Check | Why it matters for an HVAC site |
|---|---|
| HTTPS | Browsers mark plain-HTTP sites "not secure" — a bad look for someone about to give you their address |
| Indexability | One stray noindex tag removes a site from Google entirely; it happens more than anyone admits |
| Title tag | The headline of your Google listing and the strongest single on-page signal |
| Meta description | Your pitch under the headline; missing means Google improvises it |
| One H1 | The page's stated topic — zero or five H1s both blur it |
| Mobile viewport | Emergency HVAC searches happen on phones; without a viewport tag the page renders desktop-sized |
| Canonical URL | Keeps www/non-www and tracking-URL duplicates from splitting your signals |
| Structured data | JSON-LD tells engines what you do and where — machine-readable proof, increasingly read by AI |
| Social preview | og:title and og:image control how shared links render in texts and feeds |
| Image alt text | Accessibility plus context for every image — and it's the low bar most sites still miss |
How the score is built
The score weights the ten checks by how badly each one hurts when it fails — our editorial weighting, printed here so the number isn't a black box:
- Heavy (15 points each): HTTPS, indexability, title tag — failures here cost entire rankings, not positions.
- Medium (10 points each): meta description, H1, mobile viewport, structured data.
- Light (5 points each): canonical, social preview, image alt coverage.
A "warn" earns half its weight. The grader estimates on-page health only — it deliberately does not measure page speed, Core Web Vitals field data, content quality, or backlinks, and it is not a Lighthouse replacement. A site can score 100 and still never rank: fundamentals are the floor, not the ceiling.
What a low score costs an HVAC company
A site with broken fundamentals loses twice. Google ranks it below competitors whose pages resolve cleanly — and every marketing dollar pointed at it underperforms, because ads and SEO both land traffic on pages that leak. Fixing fundamentals is the cheapest work in the entire marketing stack; it's carpentry, not magic.
If your score came back under 85, the question is whether to patch the existing site or rebuild on a clean frame — our HVAC website builds exist for the second case, and our HVAC SEO program picks up where fundamentals end. For multi-location and service-area setups, service-area local SEO adds the layer this grader doesn't score.
Frequently asked questions
How do I check if my HVAC website is good?
Run it through the grader above for the technical floor: ten fundamentals, scored instantly. Then ask the question no tool scores — does the site ring the phone? A technically clean site that generates no calls has a marketing problem, not a code problem.
What's a good score?
85+ means fundamentals are handled and your growth constraint is elsewhere (content, authority, conversion). Under 60 means the basics are actively costing you rankings.
Why did my beautiful new site score badly?
Design and fundamentals are different crafts. Template builders and JavaScript-heavy frameworks routinely ship missing titles, absent structured data, and multiple H1s under a gorgeous surface — which is exactly why the grader reads your HTML instead of your homepage screenshot.
Do you store my URL or the results?
No. The scan fetches your public page, returns the results to your browser, and stores nothing.
