Seasonal Marketing Strategy for HVAC Contractors: How to Fill Your Calendar Year-Round
Key Takeaways
- AC repair searches surge over 250% above baseline in July - contractors who wait until June to increase spend pay 40% more per click than those who move in April
- Maintenance plan members generate 2.4x to 3.1x higher lifetime value than one-time customers, and top HVAC firms pull 50% or more of annual revenue from those programs
- A simple winter prep email to 2,000 past customers cost $150 and returned 17 booked jobs at $285 each - a cost per sale of $8.82
- Non-branded Google search ads cost $149 per lead on average - branded campaigns average $34, making database marketing the highest-ROI channel in slow seasons
AC repair searches spike over 250% above baseline every July, and furnace repair climbs 130% every January - according to Ahrefs keyword trend data analyzed by Stacker in 2026. Most HVAC contractors already know demand is seasonal. What kills their business is treating their marketing the same way.
Why Does Turning Your Marketing Off in the Slow Season Cost You More?
Every time you cut spend and go dark, you rebuild from zero when the season turns. Google’s algorithm drops you. Your email list goes cold. Your Google Business Profile loses momentum.
The contractors who stay busy year-round never fully turn off. They shift what they’re spending on - not whether they’re spending.
The economics are clear. According to SearchLight’s January 2026 benchmark tracking $14.9 million in Google Ads spend across 816 HVAC and plumbing contractors, the average blended cost per lead sits at $104. Non-branded search - the campaigns running when someone types “AC repair near me” - costs $149 per lead on average. Branded campaigns, where someone already knows your name and searches for you, cost just $34 per lead.
That gap is the entire argument for year-round marketing. When you stay in front of customers during the slow months, you build the brand recognition that makes the expensive peak-season keywords cheaper to compete on.
When Should You Increase Ad Spend - Before or During the Peak?
Four to six weeks before the peak hits. Not after.
When demand spikes, every HVAC company in your market bids on the same keywords simultaneously. WebFX 2024 data puts average HVAC cost per click at $29.03, projected to hit $32.77 in 2025. High-intent metro keywords like “emergency AC repair” regularly hit $22 to $40 per click. That’s not the time to start a campaign from scratch.
April 15 is a smarter time to increase AC ad spend than June 1. By June, you’re paying a premium to compete. By starting in mid-April, you build Quality Score, lower your CPC, and you’re already capturing the demand curve as it builds toward the summer peak.
The New Jersey HVAC company documented by RS Gonzales in January 2026 shows exactly what this looks like in practice. Running just three trucks in one of the most competitive, high cost-of-living markets in the country, they pulled 48 qualified Local Services Ads leads in June alone during a heatwave. Their early-season setup work - getting the LSA profile optimized and the campaign structured before demand hit - is what made that June number possible.
What Should Your Budget Actually Look Like?
ServiceTitan, working with over 100,000 contractors in 2026, recommends spending 10% to 20% of revenue on marketing if you want real growth. A 5% budget is a “maintenance” budget - you’ll tread water, not grow.
In dollar terms, that translates to $2,500 to $12,000 per month for a small HVAC business.
| Marketing Channel | Avg. Cost Per Lead | Best Season to Use |
|---|---|---|
| Branded Google Search | $34 | Year-round |
| Google Local Services Ads | $50-$60 per call | Peak season |
| Non-Branded Google Search | $149 | Peak + shoulder |
| Performance Max | $72 | Year-round testing |
| Email to Past Customers | Under $10 | Slow season |
The LSA close rate across documented contractor accounts runs around 55%, putting cost per booked job from LSA at roughly $110 per sale. That math works at nearly any average ticket price, given the HVAC average repair ticket runs $350 and unit replacements run $8,000 to $15,000.
For a deeper look at how these channels stack up strategically, comparing SEO vs. PPC for home service contractors breaks down when to lean on each and why the answer changes by season.
How Do You Market HVAC During the Shoulder Season?
Spring and fall are where most contractors hemorrhage money by doing nothing - or doing the wrong thing.
Shoulder season is not the time to push emergency repair ads. Nobody’s AC is dying in 68-degree weather. The play is preventative maintenance offers and air quality upgrades.
A basic offer: “Spring AC Tune-Up - $79.” Run that with a small Google Ads budget targeting homeowners in your service area. Simultaneously, email every customer who hasn’t called in 12 months - not a newsletter, one email with one offer.
Subject line: “Is your AC ready for summer?” That single message does more work than any campaign built around generic brand awareness.
The ROI on that email approach is not a rounding error. ServiceTitan documented a contractor who sent a “winter prep” email to 2,000 past customers at a total cost of $150 - email platform fees plus time. That email produced 17 service calls averaging $285 each, for a cost per sale of $8.82. Email marketing across the industry averages $40 in revenue for every $1 spent, according to ServiceTitan’s 2024 benchmarks.
Contractors who do slow season marketing right - database emails, tune-up promotions, and maintenance agreement pushes - report covering 30% to 50% of peak-season revenue without touching paid search budgets.
For a complete playbook on SMS outreach during slow months, text message marketing for contractors covers the channel that gets opened more than email and costs even less.
How Do Maintenance Agreements Change Your Entire Business Model?
This is the one that separates the contractors booked six weeks out from the ones refreshing their phone waiting for it to ring.
Maintenance plan members generate 2.4x to 3.1x higher lifetime value than one-time customers, according to 2026 data from Amra and Elma citing SearchLight and ServiceTitan research. The average HVAC customer lifetime value is $15,340. For top HVAC firms, maintenance programs account for 50% or more of total annual revenue.
Maintenance agreements turn the slow season into a busy season. Your tech is doing tune-ups in October instead of sitting in your parking lot. Your office manager is booking spring checkups in February instead of watching your Google Ads spend go nowhere.
Chris Hunter, President of Hunter Heat and Air - who spent nearly 15 years running his HVAC business before joining ServiceTitan as Director of Customer Relations - credited the maintenance agreement program as the central driver of year-round revenue stability. ServiceTitan reports contractors using their platform see average revenue increases of 21% in the first two years, with maintenance agreement automation cited consistently as a contributing factor.
ACHR News documented in February 2026, drawing on 30 years of working exclusively with home service contractors, that a healthy home service business generates roughly 80% of revenue from existing customers. 65% to 70% of a customer’s total lifetime value is realized in the first 18 months - which is exactly the window where you should be enrolling them in a maintenance plan, not ignoring them until something breaks.

How Do You Track Whether Any of This Is Actually Working?
You cannot manage what you cannot see. Most HVAC contractors running Google Ads have no idea which campaigns are generating booked jobs versus tire-kickers.
DUO Digital, managing ad spend across 15 or more trades companies in 2026, found HVAC Google Ads conversion rates range from 3% to 10% depending on landing page quality. Below 4% almost always means traffic is landing on your homepage. Sending clicks to your homepage is a waste of money.
A dedicated landing page for “AC Tune-Up in [City]” - with your phone number visible, a handful of reviews, and one clear offer - routinely hits 7% to 12% conversion rates. That same traffic to your homepage converts at 3% or less. Same ad spend, twice the leads.
For tracking which ads are actually producing revenue rather than just clicks, tracking PPC leads that don’t convert covers the setup most contractors skip. And if you want to understand why your site gets visitors who never call, website traffic not converting to booked jobs walks through the behavior patterns worth watching.
The contractor documented by WebRunner Media - referred to as “Max” in their August 2025 case study - committed to sharing revenue figures for every booked job over a 12-month campaign. The result: 375 leads and $13.24 in profit for every $1 spent on ads. That number is only possible when you’re tracking all the way to revenue, not stopping at clicks.
For HVAC companies building out location-specific pages to capture searches in multiple towns, service area pages for local SEO covers the structure that actually ranks - not the thin, duplicate pages that Google ignores.

Frequently Asked Questions
When is the best time to increase Google Ads spend for HVAC?
Four to six weeks before seasonal demand peaks - not after. Moving your AC campaign budget up in mid-April instead of June means lower competition and lower cost per click before every competitor enters the auction. By June, HVAC keywords in competitive metros regularly hit $22 to $40 per click according to DUO Digital’s 2026 benchmark data.
How much should an HVAC contractor spend on marketing?
ServiceTitan recommends 10% to 20% of revenue for contractors who want to grow, citing data from over 100,000 contractors in 2026. In dollar terms, that runs $2,500 to $12,000 per month for a small HVAC business. A 5% budget is considered a minimal maintenance-level spend that produces minimal results.
Do HVAC maintenance agreements actually improve marketing ROI?
Yes - significantly. Maintenance plan members generate 2.4x to 3.1x higher lifetime value than one-time customers, according to 2026 data from Amra and Elma citing SearchLight and ServiceTitan research. Top-performing HVAC firms pull 50% or more of their annual revenue from maintenance programs, which also creates a built-in slow-season workload that keeps techs busy without requiring new ad spend.
What is the average cost per lead for HVAC Google Ads?
The January 2026 SearchLight benchmark tracking $14.9 million in ad spend across 816 contractors puts the blended average at $104 per lead. Non-branded search - your primary customer acquisition campaigns - averages $149 per lead. Google Local Services Ads average $50 to $60 per call with a close rate around 55%, putting cost per booked job near $110.
Why does HVAC marketing fail in the shoulder season?
Most contractors run the wrong offer at the wrong time. Bidding on emergency repair keywords in 68-degree October weather burns budget on zero-intent searches. The shoulder season play is preventative maintenance promotions - $79 tune-up offers, maintenance enrollment campaigns, and database emails to past customers. A documented contractor case sent a $150 email campaign to 2,000 past customers and generated 17 booked jobs at a cost per sale of $8.82.
Pull your customer list from the last three years, sort it by last service date, and send a simple email to anyone who hasn’t called in 12 months. One offer. One clear call. No newsletter formatting. Do that this week before you touch your ad budget.
