HVAC SEO: getting found by people with no heat, no cooling or an aging system

What do people search when the heat or AC quits?

HVAC search behavior swings between panic and patience. A family with no heat on a January night types fast and calls the first company that looks open. A homeowner pricing a heat pump reads for weeks. Your site and profile have to catch both, and they do it with different pages.

Where you work changes the mix. A shop in a long cooling climate and a shop in a long heating climate live on different calendars, and you don't have to guess at yours. Look up "furnace repair" and then "ac repair" for your state in Google Trends to see your own curve. Trends numbers are relative popularity on a 0 to 100 scale, so read them as timing, not volume.

Which Business Profile categories should an HVAC company pick?

Your primary category is Google's main clue about what you do, and HVAC owners have a real choice to make. All of these appear in an independently maintained list of Google's categories (last revised May 2026):

• HVAC contractor. The right primary for most companies that do both heating and cooling.
• Air conditioning contractor. Worth considering as primary if cooling is nearly all your work.
• Heating contractor. A fit for heating-heavy shops, including hydronic and boiler specialists. That list includes Boiler supplier and Boiler manufacturer but no boiler repair category, so a contractor's boiler service belongs in the services list.
• Air conditioning repair service and Furnace repair service. Secondaries that match the repair side of the business.
• Air duct cleaning service and Dryer vent cleaning service. Add these only if you sell that work on its own, with your own equipment.

Google's guidelines for Business Profiles frame the test as what the business "IS", not what it "HAS", and ask for as few categories as will describe the core business. A maintenance plan is a service you offer, not a category. Selling smart thermostats doesn't make you an electronics store.

To see the current choices, click into Business category in the editor and start typing "heat", "air" or "furnace". Whatever Google suggests is the list; per its help page on categories, you can't add your own wording, and an added or edited category can trigger a fresh verification. Make the change in April or October, not during a heat wave.

A few more settings deserve attention in this trade:

• Hours. Save the 24 hours setting for a shop where a person, or an answering system that can dispatch, truly picks up at 2 AM. Set special hours ahead of Thanksgiving and Christmas, when a no-heat call can come from a house full of guests.
• Services. List them by system and job: furnace repair, heat pump installation, central AC replacement, ductless mini-split installation, boiler service, tune-ups, maintenance plans, dehumidifiers. Use the words a homeowner would type.
• Phone. Google's guidelines say the number must be under the business's direct control, so a routing number owned by a lead marketplace doesn't fit.

Paid placements sit above all of this. Google is shifting Local Services Ads over to lead-priced Performance Max campaigns inside Google Ads, starting in August 2026 with select US home service advertisers, HVAC among them, and says advertisers still pay for valid leads rather than ad clicks. That is a separate channel from your free profile; we compare them in Local Services Ads vs SEO.

How should an HVAC website be organized?

Build the site around two questions: which system, and repair or replace? That gives you a grid of pages that each match a real search.

• Repair pages by system: AC repair, furnace repair, heat pump repair, and boiler repair if you work on hydronic systems. Each should cover common symptoms, what a diagnostic visit involves and how you charge for it.
• Install pages by system: central air, gas or electric furnaces, heat pumps, ductless mini-splits, boilers. Explain what affects price, why sizing needs a load calculation, and what install day looks like.
• A maintenance plan page that lists exactly what a spring and fall visit includes and lets customers sign up online.
• Indoor air quality pages for the problems your climate produces: muggy summers and dehumidifiers, dry winters and humidifiers, allergy season and filtration.
• Financing and rebates. Link to the current program pages of your utility and the manufacturers you install rather than quoting amounts that change.
• Commercial service, if you work on rooftop units and light commercial equipment. Facility managers want response times and service agreements.

Area pages earn their place when they say something about heating and cooling in that town. HVAC gives you plenty: older neighborhoods with boilers and no ductwork (where ductless systems come up), rural areas on propane instead of natural gas, newer subdivisions with builder-grade equipment reaching the end of its life at the same time, and the utility that serves the town and its rebate program. What doesn't work is fifty copies of "AC repair in [town]". Google's spam policies describe scaled content abuse as many pages generated mainly to manipulate rankings rather than to help users. Our service page writing guide covers how to make each system page useful.

What proof helps a homeowner choose an HVAC company?

An HVAC customer is letting a stranger into the basement and may be about to spend more than they have ever spent on a single appliance. Proof that lowers both worries:

• Install photos that show workmanship: a level condenser on its pad with clearance around it, an insulated and neatly run line set, a furnace or air handler with clean duct transitions, tidy condensate routing. Include the old equipment for contrast.
• Your technicians, by first name, in uniform, next to a marked truck. People want to know who is coming to the door.
• Dealer status you can verify. Equipment makers run their own dealer finders, such as Carrier's Find a Local Carrier Expert search by ZIP code. Keep your listing there accurate and linked to your site.
• Credentials as plain text, including any license number your state expects on advertising. Requirements vary, so check yours.

Google's profile photo rules call for sharp, well-lit images with no significant alterations or excessive filters, the kind that show customers what they will actually get. Short clips work too; the profile takes videos up to 30 seconds, enough to show a quiet new outdoor unit running.

On your own pages, use file names and alt text that describe the job, such as "two-stage gas furnace replacement in an unfinished basement". Google's image SEO guidance prefers a name that says what the photo shows over whatever the camera assigned, cautions against keyword-stuffed alt text, and suggests putting images next to the text they illustrate. In your structured data, schema.org offers an HVACBusiness type, and Google's LocalBusiness documentation asks for the narrowest subtype that applies. Testimonials you host on your own site won't earn review stars in search; Google's review snippet guidelines exclude self-serving reviews about a LocalBusiness.

When should an HVAC company ask for reviews?

Time the request to the moment the customer feels the difference in the house.

• No-heat and no-cool calls: text the review link once the house is back to a comfortable temperature, usually the next day. The memory of a cold night and a tech who showed up is fresh.
• System replacements: wait until the new equipment has run through several days of real weather. On commissioning day the customer has seen a new box, not felt a comfortable house. Ask during your follow-up call a week or so later.
• Maintenance members: ask once a year after a visit, using the same message for every member, so nobody is asked twice in one season.

The HVAC version of the mistake is the small sweetener: a free filter, a discount on the next tune-up, an entry in a drawing. Google's review help page files any freebie or discount handed out for reviews under fake and misleading content, and its content policy rules out choosing whom to ask based on who seems pleased. Send every customer the same request. Sample texts are in our review request templates.

How do AI assistants handle HVAC questions?

Before calling anyone, some homeowners put their HVAC questions to ChatGPT, Gemini or Google's AI Overviews: "Why is my heat pump blowing cold air in heat mode?", "Should I repair or replace a 15-year-old furnace?", "Is a heat pump enough for a cold winter?", "How often should I change my furnace filter?" The answers are summaries built from pages the assistant found, with links to some of them.

Generic answers are easy for an assistant to write without you. What it can't produce on its own is local, specific knowledge: how heat pumps you've installed handle your coldest weeks, which utility rebate applies in your county, why so many homes in one older neighborhood have oversized furnaces. Pages with that kind of detail match a question Google's helpful content guidance tells site owners to ask: does the content clearly demonstrate first-hand expertise and a depth of knowledge?

Google's documentation for its AI features says nothing special is needed there: no extra files and no new markup. If a page can already show in regular results with a snippet, it qualifies. Its list of best practices includes keeping your Business Profile current. According to OpenAI, its OAI-SearchBot crawler is the one that surfaces websites in ChatGPT search, so confirm your robots.txt and hosting firewall let it in. Our guide to getting listed in AI search covers the rest.

Be careful with safety content. If your no-heat page tells people what to do when they smell gas, keep it to what your gas utility and local fire department advise, because an assistant may lift those lines word for word.

Which local links make sense for an HVAC company?

The best links for an HVAC company come from organizations that already send homeowners to contractors:

• Equipment manufacturers. A buyer loyal to one brand may start at its dealer locator, so make sure you appear there.
• ACCA. The Air Conditioning Contractors of America runs a find-a-contractor locator and links to state associations; check whether yours lists members.
• Your utility. If your electric or gas utility keeps a list of participating contractors for its rebate programs, ask what it takes to be on it.
• Supply houses. Distributors sometimes feature contractors from their training classes or promotions.
• Property managers, real estate agents and home inspectors who need fast equipment evaluations and keep vendor lists.
• Local news during heat waves and cold snaps, when reporters want a contractor to explain how to keep a system running and when to call for help.

Paying for links on unrelated sites is a bad trade. Google's spam policies count buying links for ranking purposes as link spam unless they carry sponsored or nofollow attributes, and warn that violating sites may rank lower or vanish from results. A link from the distributor whose training class you took is earned; a paid post on a "home comfort tips" site, with no sponsored label on the link, is what the policy describes.

How should HVAC SEO follow the seasons?

HVAC search runs on the thermometer, and pages take time to be crawled and ranked, so do the work one season early:

• Late winter: refresh AC repair, AC replacement and tune-up pages, and add photos from last summer's installs before the first warm week sends people searching.
• Late summer: update furnace, heat pump and boiler pages and your no-heat checklist. In heating climates this is also when to publish anything about getting a system checked before the first cold night.
• Spring and fall shoulders: write the replacement guides, heat pump explainers and town pages while techs have open time and you have time to interview them.
• Peak weeks: keep the profile current. Accurate hours, prompt review replies and a weekly post about real jobs matter more than new pages while the phones are ringing.

How do you measure HVAC leads from search?

Track three outcomes by source: booked service calls, new maintenance members and replacement revenue. Raw lead counts flatter sources that send cheap one-time repairs.

• Business Profile. The performance view counts phone-button taps, clicks through to your site and requests for directions, and lists the searches that showed your profile. Compare the furnace-season and AC-season months.
• Tagged profile link. Add UTM tags to the URL your profile points at, and Analytics will report profile visitors as a separate source. Google Analytics can also connect to the profile itself and report its interactions next to website data, covering the most recent six months.
• Key events. In Google Analytics, mark online bookings, estimate requests, plan sign-ups and phone taps as key events, then compare which pages earn them.
• Search Console. The performance report splits clicks and impressions by query and page. If "heat pump installation" earns impressions but few clicks, that page's title and opening need work.
• CRM. Capture the source on every call and form, carry it to the job, and report by job type. Call tracking makes the phone side reliable; see how to set up call tracking.

Nobody can sell you a guaranteed spot in the map results. Google's own local ranking page says a better ranking can't be requested or paid for. Treat any pitch that says otherwise as a reason to walk away.
