The State of HVAC Websites 2026: What 617 Real Sites Are Missing

Schema markup is a small block of code that tells search engines, in their own language, basic facts: this is a business, this is what it does, this is where. Without it, Google has to guess by reading the visible page like a person would, which it's fine at, but not perfect at, especially for something like an HVAC company where the difference between "we install furnaces" and "we install furnace filters" actually matters.

20% of the sites we looked at had none of this in place. That doesn't mean those sites are invisible online. It means Google is working with less information than it could have. For a homeowner searching "furnace repair near me" at 11pm, the businesses with clearer signals have a small, quiet edge in how they get described and categorized. The ones without schema aren't broken. They're just leaving that description up to guesswork.

The page title is the clickable blue text in search results, and it's also what shows up in a browser tab. It's one of the first things a search engine reads to decide what a page is about, and it's the first thing a person reads to decide whether to click.

13% of the sites we checked had a title that was missing, generic, duplicated across pages, or otherwise not doing the job. That's not a design flaw. It's usually a leftover default from whatever software built the site, or a title that was written once years ago and never touched again. A bad title doesn't necessarily crash a site's visibility, but it makes the business's own pitch, in the search results, weaker than it needs to be. The company is right there. The listing just doesn't say much.

A meta description is the short summary text under a page's title in search results. It's not a ranking factor most search engines weigh heavily, but it's the pitch. It's the sentence that convinces someone to click one HVAC company's listing over the next one down the page.

22% of the sites in this sample had none. When that happens, the search engine pulls in a fragment of whatever text is on the page, sometimes a sentence, sometimes a stray line from a footer. It's out of the business's hands at that point. Combined with the title and schema numbers, this points to a pattern: a lot of these gaps aren't about the site looking bad. They're about pieces of the site's back end never being filled in, probably at launch, and never revisited since.

None of this requires a developer to diagnose. An owner can check most of it in ten minutes.

• Search your own business name on Google and read your listing's title and description exactly as a stranger would see them. Does the title say what you actually do, or is it a generic placeholder?
• View your homepage's page title in the browser tab. If it just says your company name with nothing else, that's a missed line.
• Ask whoever built your site whether schema markup was set up, and for what. Business name, service area, and services offered are the basics.
• Check two or three inner pages, not just the homepage. Titles and descriptions often get set once for the homepage and never extended to service pages.

None of this is dramatic work. It's the kind of thing that sits unchecked for years precisely because it's invisible until someone looks.
