Winterization: How to Stay Booked During Your Slow Season (Revenue Hack for HVAC & Plumbing)

Winter is slow season. Here's how top contractors stay booked year-round using seasonal maintenance contracts.

Winter hits and the phone goes silent. You've got 3-4 crew members and barely enough work to keep them busy. You're either laying them off or eating payroll with zero billable hours.

But the best contractors don't have a slow season. Here's why.

The Seasonal Reality (And Why You Can't Ignore It)

HVAC and plumbing are seasonal. HVAC peaks in summer (AC install/repair) and winter (furnace maintenance). Plumbing peaks before holidays and after freeze damage. Roofing peaks in spring/fall.

The contractors who struggle financially aren't the worst technicians, they're the ones who treat slow season as "time off" instead of "revenue opportunity."

The Maintenance Contract Model

In October, before the cold hits, call your top 50 customers from last year and offer a "winterization package." For $199-399, you:

If 30% sign up: 15 jobs × $300 = $4,500 in January revenue. At $150/job in labor + materials, that's $2,250 profit during your slowest month.

Do that every winter for 5 years, and you've built a $112,500 revenue stream from existing customers, zero new marketing required.

The Plumbing Twist: Winterization Inspections

Plumbers can offer "freeze damage prevention inspections" (exposed pipes, heat tape, insulation). Same model: $199-299, 30 minutes, high closing rate because the problem is real.

Roofing? "Gutter cleaning and winter prep." Landscaping? "Winterization and spring prep plan."

Every trade has a slow season play. You just have to name it, package it, and sell it to customers who already trust you.

Month-by-Month Seasonal Calendar: Know Your Slow Spots

The first step to beating slow season is knowing exactly when it's coming. Here's a realistic breakdown by trade so you can plan outreach 60-90 days ahead of the dip.

HVAC

Plumbing

Roofing

Electrical

The pattern is clear: every trade has two to four months where revenue dips. The contractors who stay profitable during those months are the ones who plan for it — not react to it.

How to Price Your Maintenance Packages (Without Leaving Money on the Table)

The winterization package we mentioned earlier ($199–$399) is a starting point. But if you want to turn slow season into a real revenue engine, you need tiered pricing. Here's how to think about it.

Tier 1: Basic Inspection ($149–$199)

This is your door-opener. Low commitment for the customer, gets your tech on-site. Most of your upsell revenue comes from here.

Tier 2: Full Maintenance Package ($299–$449)

This is your sweet spot. High enough margin to be profitable, low enough price that customers feel like they're getting a deal. Most of your bookings should land here.

Tier 3: Annual Service Agreement ($599–$899/year)

This is your recurring revenue play. Even if only 10–15% of customers pick Tier 3, that's predictable monthly income you can count on. And those customers almost never shop competitors because they're locked into your service cycle.

Pro tip: always present all three tiers at once. Research consistently shows that when people see three options, they gravitate toward the middle one. Your Tier 2 closes at a much higher rate when Tier 1 and Tier 3 are sitting next to it.

Outreach Script Templates That Actually Get Responses

You've got the packages built. Now you need to sell them. Here are proven outreach templates for following up with past customers — because the easiest sale is to someone who already trusts you.

Text Message (Best for Response Rates)

"Hey [First Name], it's [Your Name] from [Company]. We're booking our fall maintenance slots and wanted to offer you priority scheduling before they fill up. Quick furnace tune-up is $199 and takes about 45 min. Want me to grab you a spot this week or next?"

Why this works: it's personal, mentions a specific price, creates urgency with "before they fill up," and gives a simple yes/no decision. Keep texts under 160 characters if possible, or break into two messages.

Email (Best for Detailed Packages)

Subject: Your furnace hasn't been checked since [last service date]

"Hi [First Name], last time we were at your home was [date] for [service performed]. With winter around the corner, now's the time to make sure your system doesn't surprise you on the coldest night of the year. We're running our annual maintenance special — starts at $199 for a full inspection. I've got openings [next week]. Want me to put you on the schedule?"

Why this works: it references their actual service history (which builds trust), frames the problem in terms they care about (system failing when they need it most), and ends with a direct ask.

Phone Script (Best for High-Value Customers)

For your top 20% of customers — the ones who spent $2,000+ with you — pick up the phone. A 90-second call beats any text or email.

"Hey [Name], it's [Your Name]. Just calling because we're getting into [season] and I wanted to make sure your [system] is good to go. We did [previous work] back in [month] — everything still running smooth? ... Great. We're also offering our maintenance package right now if you want to get ahead of any issues. Most of our customers grab the $299 option. Want me to get you on the books?"

The key with all of these: don't pitch cold. Reference past work. Make it feel like a check-in, not a sales call. Contractors who do this see response rates two to three times higher than generic blasts.

Upsell Opportunities During Inspections (Where the Real Money Is)

Here's the truth about maintenance packages: the inspection itself is the foot in the door. The real revenue comes from what your tech finds while they're on-site.

Train your techs to look for these during every inspection:

HVAC Upsells

Plumbing Upsells

Roofing Upsells

The average upsell per maintenance visit should land somewhere between $200 and $800 depending on the trade. That means a $299 maintenance appointment can easily turn into a $700–$1,100 ticket. Multiply that across 30–50 bookings per slow season and you're looking at serious revenue.

The key is how your tech presents it. Never say "you need this." Instead: "I noticed [issue]. It's not an emergency today, but it could become one this winter. If you want, I can take care of it while I'm here — saves you a second trip fee." That framing closes at a much higher rate because it's helpful, not pushy.

How Automated Follow-Up Keeps Leads Warm Through the Off-Season

Here's where most contractors drop the ball. You run a great fall outreach campaign, book 30 appointments, and then... nothing. The other 170 people who didn't book? They're gone. You never follow up.

That's a massive missed opportunity. Just because someone didn't book in October doesn't mean they won't book in December when their furnace starts making a weird noise. But they'll only call you if you stayed top-of-mind.

Manual follow-up doesn't scale. You're not going to text 170 people every three weeks while also running jobs. That's where automated systems change the game.

Here's what a smart follow-up sequence looks like:

Each touchpoint gives non-buyers another chance to convert — without you lifting a finger. Contractors who run automated sequences like this typically see an additional 10–20% of their original list convert over the following 60 days. On a list of 200, that's 20–40 more bookings you'd have otherwise lost.

And here's the compounding effect: every customer you book through follow-up becomes a future maintenance customer. Your list grows every year, your close rate improves because you have more service history to reference, and your slow season gets less slow every single year.

This is exactly how you generate more leads without spending more on ads. Work the customers you already have.

How AVERY Fills Your Slow Season Calendar

Everything above works. The scripts, the tiered packages, the follow-up sequences — all proven. But here's the honest question: are you actually going to do all of that manually?

Most contractors have good intentions in September. By mid-October, they've called maybe 12 people and given up because the phone tag is exhausting. That's not a discipline problem — it's a bandwidth problem.

That's why contractors use AVERY. Instead of manually calling 50 customers, AVERY texts your entire past-customer list in one shot: "Hi, it's [Company]! As temperatures drop, we're offering our annual maintenance special to protect your system. Starts at $199. Want me to grab you a spot?"

High-intent customers reply and get booked — automatically. Low-interest customers ignore it. You spend zero time on rejections or phone tag.

AVERY handles the entire follow-up sequence we outlined above. Day 3 nudge, Day 14 value message, Day 30 reminder, Day 60 last chance — all automated, all personalized with the customer's name and service history. And if someone replies at 11 PM on a Tuesday asking to book? AVERY answers instantly and locks in the appointment.

One contractor used AVERY to text 200 past customers about winter maintenance. 45 booked appointments. 30 closed. That's $8,000+ in revenue from 30 minutes of setup time.

But it didn't stop there. AVERY's automated follow-up converted another 18 bookings over the next 60 days from people who didn't respond initially. That's nearly $5,000 more in revenue that would've been left on the table with manual outreach alone.

And here's what really matters: AVERY does this while also qualifying every new lead that comes in, answering after-hours calls, and reducing no-shows with automated confirmations. Your slow season outreach runs in the background while you focus on the jobs in front of you.

Bottom Line

Slow season doesn't have to be broke season. The playbook is straightforward:

Do this consistently and your November through February stops being a cash crunch. Your crew stays employed, your skills stay sharp, and you build predictable off-season income that compounds every year as your customer list grows.

The contractors who win aren't the ones with the best technical skills. They're the ones who build systems that keep revenue flowing regardless of the season. This is how you do it.

Never Miss a Slow-Season Lead

When calls do come in during winter, AVERY makes sure every one gets answered and booked—so no lead slips through.
