When to Spend More (and When to Hold) on HVAC Marketing by Season

Most HVAC contractors ask the wrong seasonal question. They want to know when to spend more on marketing and when to pull back, assuming there’s a calendar somewhere that says July good, February bad. There isn’t one, not a universal one anyway. Utah’s swing from AC season to furnace season looks nothing like Florida’s, and building a strategy around Ogden weather doesn’t help someone reading this in Phoenix.

Here’s the real problem I see over and over. It’s not that contractors get the season wrong. It’s that nobody’s watching which campaign is actually producing, seasonal or not, so the budget gets split between a winner and a loser and Google happily spends both.

(The traffic-but-no-calls diagnostic covers the website side of this. This one’s about the ad spend side.)

The client who was running two campaigns nobody was watching

We picked up an HVAC account that came from a previous agency, and the setup told the whole story before we changed a single setting. Two Google Ads campaigns running at the same time, both live, both spending. One was pulling a cost per lead north of $600. The other was worse still. Neither one had been touched in a way that mattered.

Negative keywords weren’t dialed in, so the campaigns were bleeding clicks on searches that had nothing to do with HVAC work. Broad match was wide open, which meant Google was making the call on what counted as relevant, not anyone on the account. And sitting underneath both of those was a YouTube demand gen campaign that had been switched on and never tuned again, quietly burning budget with no one checking if it did anything.

That’s not a seasonal problem. That’s a nobody’s-driving problem. The season didn’t cause it, it just made it worse, because whatever was already broken got more expensive every time demand spiked.

The two things we actually do by season

Once the account is clean, actual seasonal strategy comes down to two moves, not a spending calendar.

• Off-season, we widen the language. When air conditioning searches die down, we shift campaign and keyword focus from “air conditioning” toward “HVAC” more broadly, so furnace and heating searches start feeding the same machine instead of getting left on the table.
• Every year, we test install against repair. Which one converts better shifts depending on the economy, not the month. Some years repair carries the account because homeowners are patching instead of replacing. Other years install pulls ahead. We test it fresh instead of assuming last year’s split still holds.

Neither of those is complicated. Both of them require someone actually looking at the account regularly, which is the part most agencies skip once the contract’s signed.

The question that actually matters

Forget “when should I spend more.” Ask this instead: do I know which campaign, which service, which piece of my marketing is actually producing leads right now, this month. If the honest answer is no, that’s the expensive part, not the season.

If “running tactics instead of a real strategy” sounds familiar, that’s the exact pattern we cover here. And if you’re deep in the weeds on the cost side of this, we broke down why HVAC marketing costs range from $50 a month to $10,000 and what actually drives that gap, or why some HVAC sites aren’t showing up on Google at all if ranking is the piece you’re missing. For how we handle Google Ads day to day, that’s covered on the Google Ads management page. More on how we approach the HVAC niche specifically lives on the HVAC industry page.
