HVAC Shoulder Season Marketing

HVAC search volume drops 65 to 75 percent in March, April, September, and October - and contractors who treat those months as a vacation hand their competitors a 6-month head start on the next peak season.

What Actually Happens to HVAC Revenue During Shoulder Season?

Most contractors feel the drop but don’t realize how predictable it is. According to industry benchmark data published by PipelineOn in June 2026, contractors who cut marketing spend entirely during shoulder season see revenue fall by 60 percent or more. Contractors who stay active and shift strategy - rather than just turning things off - reduce that drop to 30 to 40 percent.

That’s not a small difference. On a $1.5M annual business, that gap is $150,000 to $450,000.

The problem isn’t the season. The problem is treating shoulder season like a vacation.

Why Does HVAC Demand Drop So Hard in Spring and Fall?

No heat waves. No frozen pipes. Nobody’s panicking.

In peak season, homeowners call you because they have to. In shoulder season, they might call you - if you remind them. That’s a completely different marketing job, and most HVAC companies aren’t set up for it.

The ServiceTitan Spring 2024 benchmark data shows the first heat wave of summer can spike HVAC revenue by 55 to 90 percent. That spike goes to whoever already has their name in front of homeowners when the temperature hits 95 degrees. Spring shoulder season is your window to be that company.

Should You Pause Google Ads During Shoulder Season?

Do not pause. Redirect.

SearchLight Digital’s March 2026 analysis of $14.9 million in real HVAC and plumbing ad spend across 816 contractors breaks down why this matters so clearly it’s almost unfair.

Campaign Type	Average Cost Per Lead
Branded Search	$34
Performance Max	$72
Local Services Ads	$51 (44% book rate)
Non-Branded Search	$149
All Channels Blended	$104

During shoulder season, shift budget from non-branded search ($149/lead) to branded campaigns ($34/lead) and LSAs ($51/lead). Your audience is smaller, but competition is thinner and your existing brand recognition works harder.

If you’re not tracking which campaigns are actually booking jobs, you’re flying blind. The guide to tracking PPC leads that don’t convert is worth reading before you touch your campaign settings.

An HVAC owner on r/sweatystartup posted in early 2026 about cutting his self-managed Google Ads cost per lead from $187 to $94 after handing campaigns to a specialist agency - same budget, same offer, twice the leads. The opposite also happens: a plumbing-and-HVAC operator on ContractorTalk fired his agency, ran his own ads, and watched his cost per booked job double in 60 days. The lesson is that optimization matters more than who’s doing it, but someone has to actually know what they’re doing.

What’s the Cheapest Way to Get HVAC Leads During Slow Season?

Email your past customers. Seriously, just do this today.

A Blue Corona client sent a single “Beat the Summer Rush” AC maintenance email to their existing customer list in 2024. No paid ads. No agency retainer. It generated 122 service appointments in two weeks at zero additional ad spend.

One anonymous HVAC client profiled by Contractor Marketing Pros sent a “winter prep” email to 2,000 past customers. The email platform cost $150 total. It generated 17 service calls at an average ticket of $285, landing a cost per sale of $8.82.

That result stands in sharp contrast to the industry average CPL of $153 across all channels, per WebFX’s May 2026 HVAC marketing benchmarks. Email is not glamorous. It is, however, the cheapest and fastest way to fill your fall calendar.

How Do Maintenance Agreements Change the Shoulder Season Math?

They change it completely.

According to ServiceTitan’s 2024 State of Field Service report, HVAC companies using automated maintenance agreement workflows convert 28 to 34 percent of service calls into agreements. Companies relying on technician verbal pitches alone convert only 8 to 14 percent.

Here’s why that matters for cash flow: maintenance plan customers have an average lifetime value of $47,200 vs. $15,340 for one-time customers, according to 2026 industry benchmarks from SmartAC. That’s a 3x difference in revenue from the same customer acquisition cost.

Top HVAC companies generate 15 to 25 percent of annual revenue from maintenance agreements. That’s recurring revenue that doesn’t require anyone to panic-call you in August.

Shoulder season is the best time to sell these plans because homeowners are calm, budgets aren’t stretched by emergency repairs, and a tune-up visit gives your technician a natural opening to present the offer. If your team is still relying on verbal pitches, the conversion gap between 8 percent and 34 percent represents real dollars leaving your business every single week.

What the Katz Brothers Did When Shoulder Season Hit Hard

The Katz brothers at Trio Heating & Air had a brutal 2024 shoulder season - a slowdown many attributed to a post-pandemic hangover where four years of system replacements had already happened.

Their response included door-knocking, flyers, and targeted messaging built around financial pain points. They started offering financing because, as Michael Katz put it, “many people don’t have $2,000 sitting in their bank account since the issue caught them off guard out of nowhere.”

They also bought the phone lines of HVAC companies that had shut down and redirected those calls to their own service line. That’s near-zero-cost lead acquisition, and it worked.

The lesson isn’t to copy every tactic they used. The lesson is that shoulder season rewards contractors who stay aggressive while everyone else goes quiet. Creative outreach during a slow period hits harder because the noise level is lower.

Does Your Online Reputation Affect Shoulder Season Lead Volume?

More than most contractors realize, and in a very specific way.

BrightLocal’s 2024 Consumer Review Survey found that 87 percent of homeowners read reviews before hiring a local business, and 57 percent won’t even consider calling a company with less than 4 stars. That’s not a soft brand metric - it’s a hard filter sitting between your phone ringing and silence.

In shoulder season, when homeowners are shopping proactively rather than calling in a panic, your review score matters even more. An emergency at 11pm on a 100-degree day means they’ll call whoever shows up in search. A tune-up appointment booked on a Tuesday morning means they’re reading every review you have.

Your Google Business Profile is doing more work than your paid ads in those moments. If it isn’t optimized, the why your Google Business Profile isn’t showing breakdown explains the common fixes. For video reviews that actually convert browsers into callers, the video testimonials guide walks through the setup.

How Should You Shift Your Budget When Search Volume Drops 65-75%?

Contractors make the same mistake repeatedly: they leave their peak-season campaign structure completely intact and just lower the budget. That’s the wrong move.

When search volume drops, non-branded keywords get expensive and produce fewer results. Average HVAC cost per click hit $29.03 in 2024 and is projected to reach $32.77 in 2025, per WebFX, with CPC ranging from $18 to $62 depending on location and competition. Shoulder season is when you lean into the cheaper, higher-intent channels.

Local Services Ads average $51 per lead with a 44 percent book rate. That book rate beats most paid search campaigns even at peak season performance. If you haven’t set up LSAs yet, the Thumbtack vs. Google LSA comparison shows how they stack up against other lead sources.

Alongside paid channels, your website’s ability to convert the traffic you do get becomes more important when overall volume is lower. If visitors are landing but not calling, the website traffic not converting breakdown identifies the friction points worth fixing before peak season returns.

For tracking whether your shoulder season campaign shifts are actually working, campaign performance tracking gives you the measurement framework to know if the changes are moving the needle.

Building a Shoulder Season System That Runs Every Year

The contractors who suffer least in shoulder season aren’t doing heroic things. They’re running the same plays on a calendar every single year.

That system looks like this: pull lapsed customers in late August and late February, send a single reactivation email with a maintenance offer, shift Google Ads budget toward branded and LSA campaigns, and make sure every technician on a fall or spring service call is presenting a maintenance agreement. None of these steps are complicated. Most HVAC companies simply skip them.

The follow-up process matters as much as the initial outreach. Sending one email and calling it done leaves most of the revenue on the table. The workiz follow-up system for contractors covers how to automate the sequence so nothing falls through the gaps.

Shoulder season is also the right time to fix anything broken in your lead pipeline - tracking, website speed, call handling - before demand returns and every missed lead costs more. The website speed and lead conversion guide is worth a read if your site hasn’t been audited recently.

Frequently Asked Questions

When is HVAC shoulder season, and why does revenue drop so sharply?

HVAC shoulder season runs primarily through March, April, September, and October in most of North America. Search demand drops 65 to 75 percent during these months because neither cooling nor heating emergencies are driving calls. Contractors who cut marketing spend entirely during this period report revenue drops of 60 percent or more.

How much does an HVAC lead cost during shoulder season vs. peak season?

The blended average HVAC Google Ads cost per lead is $104, according to SearchLight Digital’s March 2026 analysis of $14.9 million in ad spend across 816 contractors. During shoulder season, branded campaigns can drop that to $34 per lead because competition thins out and your existing audience is cheaper to reach.

What is the best low-cost marketing channel for HVAC during slow season?

Email reactivation to past customers delivers the highest return with the lowest cost. One anonymous HVAC client profiled by Contractor Marketing Pros sent a winter prep email to 2,000 past customers for $150 total and generated 17 service calls at a cost per sale of $8.82.

Do HVAC maintenance agreements actually help with shoulder season cash flow?

Yes, significantly. According to ServiceTitan’s 2024 State of Field Service report, companies using automated maintenance agreement workflows convert 28 to 34 percent of service calls into agreements, compared to 8 to 14 percent for verbal pitches alone. Those members generate a lifetime value of $47,200 vs. $15,340 for one-time customers.

Should I pause Google Ads during HVAC shoulder season to save money?

Pausing entirely usually costs more than it saves. When you go dark, competitors take your search real estate and you lose brand recall right before peak season ramps up. Contractors do better by shifting budget toward branded campaigns and Local Services Ads, which average $51 per lead with a 44 percent book rate.
