This HVAC contractor was excellent at converting customers — their close rate and reviews were strong. But their lead flow was completely at the mercy of the weather. Peak season was hectic; shoulder season was thin; the slow months meant half-utilised technicians on full salaries. Here's how moving to a monthly lead subscription evened out the revenue curve and changed what was possible for the business.

The Problem
This HVAC business had been operating for nine years. Their peak-season performance was genuinely strong — from late May through August and again in November and December, they were running full crews with work booked two weeks out. Their average job mix was roughly 60% new system installations and replacements (residential), 30% service and repair, and 10% commercial maintenance contracts.
The problem was the calendar gaps: late winter through early spring and the September–October window. During those six to eight weeks per gap, inbound calls dropped to almost nothing. The crew had to be kept on — losing skilled HVAC technicians and re-hiring in peak season is a worse outcome than carrying the payroll through the slow months — but utilization fell to around 40%.
They had tried running ads during the slow periods to fill the gap. Results were inconsistent at best. In February, there simply isn't the same pool of homeowners actively searching for new HVAC systems. The demand isn't there to respond to. Standard pay-per-click advertising can only capture existing demand — it can't manufacture it.
What the slow months do have, however, are homeowners who can be reached with a maintenance, tune-up, or pre-season readiness offer. This type of work isn't high-value per ticket, but it keeps crews working, builds customer relationships, and consistently reveals systems that need replacement — which is where the high-margin revenue lives. The problem was that the business had no systematic way to find and book these customers in bulk.
"I'm paying three guys year-round but I only need all three of them for maybe seven or eight months. The rest of the time I'm essentially paying for capacity I can't fill. If I could find a way to keep all three busy through the shoulder season, the whole business math changes."
The Analysis
Paid advertising works by capturing people who are already searching. In peak HVAC season, search volume for AC repair, furnace installation, and system replacement is high — the demand pool is large and ads work well. In shoulder season, that pool shrinks dramatically. You can lower your bids and increase your spend, but you can't generate searches that aren't happening.
Pre-season maintenance is a well-understood concept in HVAC — homeowners who get a system check in March before they need AC, or in October before they need heat, avoid breakdowns at the worst time. The problem is that most homeowners don't think about it until they have a problem, and they're not actively searching for it.
Reaching these customers requires a different approach to lead generation: proactive outreach rather than reactive ad capture. We identify homeowners in the service area with older systems (8+ years) who haven't had a maintenance visit recently, and deliver them as maintenance or pre-season check leads. The conversion to a booking is lower than a replacement lead — but it's steady, and a meaningful percentage of maintenance visits convert to system replacements once the technician is on-site.
For this contractor, we structured a split subscription: 20 replacement and high-intent service leads per month (the kind they were already familiar with), plus 10 maintenance and pre-season leads specifically targeted at the shoulder-season demand gap.
A maintenance visit ticket might be $150–$250. That looks modest compared to a $6,000–$12,000 system replacement. But of the maintenance visits this business completed in the first year, 28% resulted in a follow-up replacement recommendation that was accepted within 90 days. Those jobs averaged $7,400.
A maintenance lead that converts to a maintenance visit that converts to a system replacement produces the same final revenue as a direct replacement lead — but the journey is spread across two visits, which keeps the crew utilised during the slow months while setting up the high-margin work that follows.
Over the course of the year, the maintenance lead stream turned out to be the highest return-on-investment component of the subscription, not despite its lower per-ticket value, but because of the downstream replacement work it generated.
A business owner who knows they'll receive 30 qualified leads next month can plan meaningfully: staff decisions, parts inventory, job scheduling. A business owner who doesn't know whether they'll get 10 calls or 50 is operating reactively, and reactive operations tend to be less profitable than planned ones.
For this contractor, switching from an unpredictable ad-driven model to a flat monthly subscription removed a significant source of business anxiety and replaced it with a planning input they could actually rely on.
The Solution
We set up a blended monthly subscription of 30 leads: 20 replacement and high-intent service leads (the existing business model) plus 10 maintenance and pre-season leads (the shoulder-season gap filler). The split was designed to keep revenue density high in peak months while maintaining crew utilization in off-peak periods.
During onboarding we mapped the contractor's historical revenue by month, identified the specific weeks where utilization had historically fallen below 60%, and set the lead delivery calendar accordingly. Maintenance leads are delivered on a higher cadence in February–April and September–October; replacement leads are weighted toward May–August and November–December.
This isn't a static split — the calendar is reviewed quarterly and adjusted if the business's workload pattern shifts.
Maintenance leads are pre-qualified differently from replacement leads. We identify homeowners with systems 8 years or older who haven't had a recorded service visit in the last 12 months, confirm they own the property, confirm the address is within the service area, and confirm they're open to scheduling a visit within two weeks.
The qualification call is more conversational than an emergency replacement call — it's about scheduling, not urgency. But by the time the lead reaches the contractor, the homeowner has already agreed to a visit in principle.
Every lead — replacement or maintenance — is delivered the same day it clears qualification. The delivery includes the homeowner's name, address, phone, system age (where available), and a brief note on what the homeowner said during qualification about the job.
For this contractor, having context before the call meant their technicians arrived better prepared. Knowing that the homeowner's furnace is 14 years old and they've noticed longer heating times is more useful than arriving cold and diagnosing from scratch.

Seasonality affects almost every HVAC business to some degree. Some indicators that the pattern above matches your situation:
You have two or more months per year where your crew is significantly underbooked relative to their available hours
You've considered laying off technicians in slow season but know the cost of re-hiring and re-training in peak season is worse
Ad spend in shoulder months produces significantly fewer leads than in peak months, at a higher cost per lead
Cash flow between July and March creates real operational strain despite a profitable business overall
You don't currently have a systematic way to offer maintenance services to homeowners who aren't yet in a crisis
Growth is constrained by unpredictable lead flow rather than by your team's ability to do the work
Maintenance leads are homeowners who've agreed, during our qualification call, to schedule a service or maintenance visit. They're not expecting a hard sales pitch — they've agreed to let a technician assess the system. The framing is service, not sales. What happens after the technician is on-site is a natural result of the inspection: if the system has a problem, the homeowner is informed, and a repair or replacement conversation follows organically. This context makes the conversation much more receptive than a cold outbound call.
Yes. Every business has a slightly different seasonal pattern based on their region and service mix. During onboarding we review your historical booking data and map lead delivery to your specific calendar. If your slow period is different from the typical HVAC pattern — for example, if you're in a climate where heating demand is more significant than cooling — we structure the delivery schedule around your actual seasonality rather than a generic model.
The maintenance-to-replacement conversion rate depends heavily on the age profile of the systems you're visiting. For leads targeted at systems 8 years or older, the rate in this case study was 28% within 90 days. For a portfolio with a higher proportion of 12+ year systems, the rate tends to be higher. We set expectations conservatively at 15–20% and treat anything above that as upside. Even at 15%, 10 maintenance visits per month produces 1–2 replacement jobs, which is significant additional revenue during months that would otherwise be quiet.
We can deliver both. This case study focused on a primarily residential contractor, but we work with businesses that want commercial maintenance contract leads, light commercial service leads, or a mix of both. Commercial qualification is slightly different — we're confirming building ownership or facility manager authority rather than homeownership — but the delivery and exclusivity model is the same. Specify your preference during onboarding and we build the subscription accordingly.
If you have skilled technicians you can't keep fully booked year-round, the problem isn't your team — it's your lead source. Let's look at what a consistent monthly pipeline would change for your business.
