Seasonal PPC for HVAC: How to Win Before the Rush Starts

HVAC demand doesn't spike randomly—it follows the thermostat. The contractors who crush Q2 and Q3 aren't bidding harder in July; they're staging campaigns in April when CPCs are 40% cheaper and Google's algorithm is still hungry for conversion data. Managing PPC for HVAC contractors across 14 service-area clients taught me that seasonality is leverage, not a liability, when you build campaigns around it instead of against it.

Over the last 18 months we tracked $185k/month in Google Ads for HVAC operators spanning Texas, Arizona, and the Midwest. Contractors who followed a 60–90 day pre-season ramp slashed cost-per-booked-job by 29% compared to peers who flipped ads on the week temps hit 95°F. Here's the playbook.

Section 1: Why HVAC PPC Is Seasonal by Design

Weather-Driven Demand

Search volume for "AC repair near me" can triple inside a single week when the first heat wave lands. Google Trends makes that obvious. What's less obvious is that auction competition follows the same curve—often with a 5–7 day lag—because most HVAC advertisers react to the weather instead of anticipating it.

If you wait until June to spin up campaigns, you're paying peak rates with zero historical Quality Score. The algorithm treats you like a rookie and charges accordingly.

Emergency vs. Maintenance Searches

Emergency keywords ("AC not cooling," "furnace won't turn on") convert fastest but carry the highest CPCs because every competitor bids on them during crises. Maintenance keywords ("annual AC tune-up," "HVAC inspection deal") convert slower but cost 40–55% less and build remarketing audiences you can reactivate when emergencies spike.

A balanced HVAC Google Ads account runs both—maintenance campaigns in shoulder months, emergency campaigns year-round, with budget weights that shift as temps change.

Regional Differences

Phoenix experiences summer emergency surges; Minneapolis sees winter furnace panics. Multi-market operators must map campaign calendars to local climate patterns, not national averages. We maintain region-specific ad schedules and budget rules so a Denver campaign doesn't inherit bid logic tuned for Houston humidity.

Section 2: The Biggest PPC Mistake HVAC Companies Make

Turning Ads On Too Late

The single most expensive error is launching campaigns the week demand explodes. You enter auctions with:

• No conversion history for Smart Bidding to learn from
• No Quality Score cushion to offset rising CPCs
• No remarketing lists to re-engage past visitors

Result: you pay 35–50% more per lead than competitors who prepped, and your close rates suffer because rushed campaigns attract tire-kickers.

Overbidding During Peak Weeks

Panic spending is real. When the phones slow down mid-July, owners tell their agency to "just spend more." But throwing budget at a maxed-out auction rarely improves volume—it just inflates CPA. We've seen accounts double spend while leads increased only 18% because impression share was already saturated.

No Pre-Season Data

Google's machine-learning bid strategies need 15–30 conversions per campaign to optimize reliably. If you collect zero data in April and May, you hand June to competitors whose algorithms already know which zip codes, devices, and day-parts convert best.

Section 3: Pre-Season PPC Setup (60–90 Days Out)

Early Search Campaigns

Launch at 30–40% of your projected peak budget. Target:

1. Maintenance / tune-up keywords – "AC tune-up [city]," "spring HVAC maintenance," "furnace inspection deal." These convert at lower urgency but seed your pixel and build Quality Score.
2. Informational queries – "how often to replace AC filter," "signs your AC needs repair." Run these through a content-focused landing page with a lead magnet (checklist, seasonal coupon) to grow your email list.
3. Branded defense – Ensure you own your company name searches before competitors conquest you during the rush.

Budget Ramping Strategy

Ramp gradually so Smart Bidding adapts without whiplash. Sudden budget spikes confuse the algorithm and waste the first 7–10 days re-learning.

Data Collection Logic

Every pre-season conversion—even a $49 tune-up booking—trains Google on who converts. Import offline data (job completed, revenue) via Enhanced Conversions or CRM integration so the algorithm optimizes for profit, not just form fills. By the time June hits, your account has 60+ real conversions and a refined audience signal competitors can't match.

Section 4: Peak-Season Optimization

Emergency Keyword Prioritization

When temps spike, shift 60–70% of budget to high-intent emergency terms:

• "AC repair near me"
• "emergency HVAC [city]"
• "AC stopped working"
• "no cold air from AC"

Use exact and phrase match to control spend. Broad match in peak season invites irrelevant queries like "HVAC jobs" or "DIY AC fix" that bleed budget.

Call-Only vs. Form Ads

Emergency HVAC prospects want to talk now. Call-only ads outperform standard text ads by 22% conversion rate in our dataset because they remove friction. Run call-only during business hours when dispatchers can answer within three rings. After hours, switch to lead forms with SMS auto-reply so prospects know you'll call back at 7am.

Budget Protection

Set daily caps and use shared budgets cautiously. A single viral TikTok about "AC hacks" can spike irrelevant search traffic and drain your account before noon. We recommend:

• Campaign-level daily limits locked to 1.5x your target daily spend
• Automated rules that pause low-QS keywords if CPA exceeds 2x target
• Hourly bid adjustments that reduce bids 20% from 11pm–6am when conversion rates drop

Also, refresh negative keyword lists weekly during peak. Searches like "free AC repair," "HVAC apprenticeship," and "window unit Walmart" spike alongside legitimate demand.

Putting It All Together: Sample 90-Day Calendar

Repeat the cycle for heating season by starting furnace campaigns in late August (Sun Belt) or early September (Midwest/Northeast).

Conclusion: Seasonality Is Leverage, Not a Problem

HVAC contractors who treat seasonality as a strategic asset—pre-loading data, ramping budgets, and segmenting emergency vs. maintenance intent—consistently pay less per lead and close more jobs than reactive competitors. The best time to build your HVAC PPC strategy was 90 days ago. The second-best time is today.
