SEO vs Google Ads for HVAC Companies: Which Gets More Calls?
I ran a 130-employee HVAC and plumbing company for over 15 years. We spent hundreds of thousands of dollars on both SEO and Google Ads. Here's what actually worked, what didn't, and what I'd do differently if I were starting over today.
Every HVAC contractor I talk to asks the same question: "Should I be doing SEO or Google Ads?" The honest answer is that you probably need both, but the right mix depends on where you are in your business. Let me break down exactly how each channel works for HVAC companies, what they cost, and when each one makes sense.
This isn't theory. I ran an HVAC and plumbing company that grew to 130 employees and made the Inc. 5000 list four times. I've personally managed Google Ads campaigns spending $30,000+ per month and watched SEO compound into our single biggest lead source. I've seen what works and what drains your budget.
How HVAC SEO Works
HVAC SEO is the process of getting your company to appear in Google's organic (non-paid) results when someone searches for terms like "AC repair near me," "furnace replacement [city]," or "HVAC company [city]." It also includes ranking in the Google Maps 3-Pack, which is often the most valuable real estate for local HVAC companies.
The three pillars of HVAC SEO are: your Google Business Profile (GBP), your website's on-page optimization, and the authority signals pointing to your site (reviews, citations, and links from local sources). Get all three right and you can dominate your market without paying per click.
What HVAC SEO includes:
How Google Ads Works for HVAC
Google Ads (formerly AdWords) lets you pay to appear at the top of search results instantly. You bid on keywords like "emergency AC repair" and pay each time someone clicks your ad. For HVAC companies, this also includes Local Service Ads (LSA), which appear above regular Google Ads and charge per verified lead rather than per click.
The advantage of Google Ads is speed. You can launch a campaign today and get calls tomorrow. The disadvantage is that the moment you stop paying, the calls stop. There's no compounding effect the way there is with SEO.

Why Most HVAC Companies Need Both
Ads Fill the Gap While SEO Builds
SEO takes 3 to 6 months to mature. Google Ads keeps the phones ringing while you wait. Think of ads as your short-term revenue and SEO as your long-term asset.
Double the Visibility on Page One
When you rank organically AND run ads, you take up more real estate on the search results page. Studies show this increases total click-through rate by 25% to 50%.
Ads Data Improves Your SEO
Google Ads tells you exactly which keywords convert to calls. Use that data to prioritize your SEO content and service pages. We do this for every client.
Real Numbers from Running a 130-Employee HVAC Company
These aren't industry averages from a blog post. These are numbers from running an actual HVAC and plumbing company that made the Inc. 5000 list four times.
These numbers will vary by market, competition level, and how well your campaigns and SEO are managed. But they give you a realistic baseline for planning your HVAC marketing budget.
