When I built Brightvale Heating & Air, a demo website for a fictional HVAC company in Austin, Texas, I kept a list of every decision that affected one thing: whether a visitor with a broken air conditioner would pick up the phone. This article is that list, written up so HVAC owners can check their own website against it.
Brightvale is a demo business, not a real company, so I can’t show calls or rankings. What I can show is what I built, what went wrong in testing and what I changed. The speed figures below come from Google PageSpeed Insights lab tests I ran in November 2026.
1. Put the phone number where a thumb can reach it
Most people looking for AC repair are on a phone and in a hurry. On Brightvale, every page has click-to-call buttons, and on phones a sticky “Call now / Free quote” bar stays at the bottom of the screen. If a visitor has to scroll to the footer to find your number, many of them will go back to the search results instead.
2. Give every service its own page
One “Services” page that lists everything is hard for visitors and gives Google little to work with. Brightvale has four service pages: AC repair, AC installation, heating and maintenance. Each one follows the same structure:
- Warning signs that the customer needs this service
- What is included in the visit
- Pricing notes, so people know what to expect
- A short FAQ with the questions people actually ask
This structure answers the customer’s questions in the order they ask them, which is also what makes the page useful in search.
3. Build city pages only for areas you really serve
Brightvale has four city pages: Austin, Round Rock, Cedar Park and Pflugerville. City pages are useful when each one helps people in that area, for example by confirming you cover their town, showing local details and linking to the right services.
Be careful here. Google’s spam policies treat near-identical pages made only to rank for many place names as doorway pages. A page where only the city name changes is a risk, not an asset. Write fewer city pages, and make each one genuinely about that area.
4. Keep the quote form short
The Brightvale quote form asks for six things: name, phone, email, ZIP code, service and urgency. Each field has a reason. ZIP code tells you if the job is in your area, and urgency tells you who to call back first. Anything more can wait for the phone call.
5. Show the trust signals a homeowner looks for
People are letting a technician into their home, so trust matters as much as design. A real HVAC website should show license and insurance details, real photos of the team and verified customer reviews. Brightvale is a demo, so it does not have real reviews, and I did not invent any. For a real launch, these are the first things I would add.
6. Write a unique title and one H1 for every page
With Rank Math, I wrote a unique SEO title, meta description and focus keyword for every page. During the check I also found a page with two H1 headings and removed the duplicate. One clear H1 per page tells visitors and search engines what the page is about.
7. Add schema markup that matches the page
I added structured data (JSON-LD) so search engines can read the business details clearly:
- HVACBusiness on the home page
- Service and FAQPage on each service page
- FAQPage on the city pages
One honest note: Google currently shows FAQ rich results mainly for government and health websites, so FAQ markup will not usually create a special search result for an HVAC company. It is still valid markup, but the real value is the FAQ content itself.
8. Check your fonts, not just your images
This was the biggest lesson from the project. The AC repair page scored 87 on mobile, with a Largest Contentful Paint (LCP) of 4.1 seconds. The images were already optimized. The real cause was a Google Font that delayed the main text from appearing.
I switched the body text to a system font stack and tuned LiteSpeed Cache (browser cache, minified CSS and JavaScript, deferred JavaScript, and lazy-loaded images with the hero image excluded). The page then scored 100 on mobile with an LCP of 1.1 seconds.
I also tested loading Google Fonts asynchronously, but it caused the layout to shift as the font loaded, so I left that option off. A faster score is not worth a page that jumps while people read it.
9. Fix contrast so everyone can read the buttons
The home page started with an accessibility score of 93. The orange buttons did not have enough contrast with their white text, and some text links were only shown by color. I darkened the buttons, underlined text links and made the footer text easier to read. Accessibility rose to 100.
10. Connect the website to Google before launch
Brightvale is set to noindex on purpose, because it is a demo. For a real HVAC company, the launch list would include submitting the sitemap in Google Search Console and making sure the business name, phone number and service areas match the Google Business Profile exactly.
The results in one table
| Test (PageSpeed Insights, November 2026) | Before | After |
|---|---|---|
| AC repair page, mobile performance | 87 | 100 |
| AC repair page, mobile LCP | 4.1 s | 1.1 s |
| Home page, accessibility | 93 | 100 |
| Home page, desktop performance | not tested | 100 |
These are lab scores, which move a few points between runs. They show that the site is fast and accessible. They do not measure calls, leads or rankings.
What this checklist will not do
No checklist can guarantee a top position on Google. Local rankings also depend on your Google Business Profile, your reviews, your distance from the person searching and your competition. What a well-built website does is make sure that when someone finds you, calling you is the easy next step.
