Every June, an HVAC contractor in Tulsa opens their Google Ads dashboard and finds their cost per click has quietly climbed 40 or 50 percent from where it sat in April. Nothing about the campaign changed. The keywords are the same, the budget is the same, the landing page is the same. What changed is that every other HVAC company in the metro started bidding on the exact same handful of phrases the same week the heat index crossed 105.
It's Not Google, It's Everyone Else Bidding Too
Google Ads runs on an auction. When ten HVAC companies in Tulsa are all bidding on “ac repair near me” during the same heat wave, the price to win that click goes up for everyone, not because Google decided to charge more, but because demand for the same handful of clicks spiked all at once. This is entirely predictable. It happens on the same seasonal schedule every year, which means it's also entirely plannable for.
The Fix Isn't a Bigger Budget, It's a Smarter Bid Strategy
Throwing more money at the same flat bid strategy just means paying the inflated summer price for more clicks, not paying a lower price. The better move is separating true emergency intent (“ac not cooling,” “emergency ac repair”) from routine intent (“ac tune up,” “annual maintenance”) into different campaigns, and bidding aggressively only on the emergency terms where a call converts almost immediately. Routine maintenance searches can run on a lower, steadier bid year-round.
Start Bidding in April, Not June
Google's auction rewards accounts with an established click and conversion history: a campaign that's been running steadily since spring generally pays less for the same keyword than one that switched on cold the week of the first heat wave. Contractors who wait until their phone stops ringing to turn ads on are starting the season already paying the new-account premium on top of the seasonal premium.
What To Do When the Budget Runs Out by Noon
A daily budget that gets exhausted by lunchtime during a heat wave means the campaign goes dark for the rest of the day, including the after-work hours when a lot of homeowners actually search. It's also worth making sure every one of those calls gets answered, since a heat-wave phone line gets overwhelmed just as fast as the ad budget does. Ad scheduling and bid adjustments by time of day can keep a smaller budget stretched across the hours that matter most, instead of burning it all in the first few hours of morning searches.
- Split emergency from routine keywords. They shouldn't share a bid strategy.
- Run a baseline campaign year-round, even at low spend, so the account has history before the spike hits.
- Set ad scheduling, so a capped daily budget doesn't disappear before the evening rush of searches.
