How to Sell HVAC Maintenance Plans (And Use Them to Fill Your Slow Season)

Only 30% of homeowners ever schedule preventative HVAC maintenance on their own. That other 70% is sitting in your database right now, waiting for you to call them. If you’re not selling maintenance plans aggressively, you’re leaving recurring revenue on the table every single slow season.

What Does the Slow Season Actually Cost an HVAC Contractor?

The math is brutal. A typical contractor generating $45,000 a month during peak season drops to $18,000 - $22,000 in the shoulder months. That’s a $23,000+ monthly gap. Stretched across a full slow period, you’re looking at roughly $47,000 in missing annual revenue.

One Phoenix-area contractor earned $180,000 during peak summer, then watched that number fall to $45,000 the following winter. That’s not a slow season. That’s a business with a hole in it.

Maintenance plans are how you plug that hole. The ACCA reports that recurring service agreements now represent 55% of HVACR industry revenue. At the company level, a well-run maintenance program can account for 50% or more of annual revenue.

Why Maintenance Plans Work Better Than Any Ad You’ll Ever Run

Paid ads are expensive. According to BaaDigi’s client reporting across 15+ HVAC campaigns run between 2024 and 2026, Google Ads clicks run $8 - $35 each depending on your market. Factor in a landing page conversion rate and you’re looking at $75 - $150 per lead for installs and emergency calls.

A maintenance plan customer costs you a fraction of that. Past customers convert at 60% lower cost than new leads from paid advertising. And once they’re on a plan, they stay.

Industry benchmarks show HVAC companies retain 80 - 90% of maintenance agreement members, compared to just 40 - 60% of one-time customers. If you’re curious how your paid spend stacks up against organic and referral channels, the breakdown in this SEO vs. PPC comparison for home service businesses is worth a look before you increase your ad budget.

Butch Welsch runs an HVAC operation in St. Louis with around 5,000 maintenance agreement customers. He explained it plainly in a Ferguson trade publication interview: “Our maintenance agreements make the customers feel like we are their contractor. They will look to us if they have a breakdown rather than just randomly calling someone else.”

That loyalty is worth more than any Google Ad you’ll ever write.

How Much Should You Charge for an HVAC Maintenance Plan?

According to BDR’s 2026 HVAC Industry Trends report, the average maintenance agreement price is $225 per year. The broader market range sits at $150 - $500 per year for residential, with higher pricing for multi-system homes or IAQ add-ons, per Housecall Pro’s 2026 HVAC Pricing Guide.

Most contractors who underprice their plans make the same mistake: they price based on what a competitor charges, not what their actual costs are. Labor, drive time, overhead, and consumables all need to be in that number.

Here’s a simple benchmark table to gauge where your plan pricing should land:

Plan Tier	Annual Price	What’s Included
Basic (1 system)	$150 - $225	One tune-up, filter check, priority scheduling
Standard (1 system)	$225 - $350	Two tune-ups, discounted repairs, priority scheduling
Premium (2+ systems)	$350 - $500+	Two tune-ups per system, IAQ check, parts discount

Price your plan so the gross margin holds up even when a tech spends 90 minutes on-site. If you’re not sure your service page communicates the value of a plan correctly, this guide on writing service pages that rank and convert covers how to structure the offer.

What’s the Real Revenue Upside of a Maintenance Contract Base?

The plan fee itself is almost a secondary concern. The bigger number is pull-through revenue.

Mike Rosone, speaking in a BuildOps expert interview, broke it down directly: pull-through work has the potential to generate $1 to upwards of $3 in additional revenue for every dollar of maintenance agreements in place. His example: a contractor with a $3 million contract base at a 2:1 pull-through ratio is looking at $6 million in additional revenue from that same customer base.

A ServiceTitan survey of 1,014 commercial service business owners (conducted by Thrive Analytics) backs this up. 75% of contractors reported getting more than 20% in additional revenue from pull-through work tied to maintenance agreement customers.

Michael DeRitis, a contractor in Parkland, New York, explained how his crew captures pull-through revenue without being pushy. His approach centers on conversation during every visit: “Seeing our customers face-to-face every few months is a blessing in disguise. We make sure to pick their brains about the HVAC system. What they like. What they don’t like. What they wish they can change.”

He continued: “This firsthand conversation allows us into their world and enables us to help them with what they need.” That’s not a sales tactic. That’s relationship-building that turns into humidifier installs, duct cleaning jobs, and system replacements you’d never get from a one-time customer.

How Do You Actually Market and Sell Maintenance Plans?

Start with your existing customer list. Not Google. Not Facebook. Your database.

Past customers cost 60% less to convert than new paid leads. If your office manager is sitting on 500 - 1,000 past customer records and nobody is calling them about a maintenance plan, that’s a revenue problem disguised as a slow season.

For outbound, a simple script works fine. Call customers from the last 12 - 24 months, mention their system by name, and offer the plan with one clear benefit - priority scheduling is the one that closes fastest. For paid media, Facebook can work well as a low-cost entry point, with reliable data showing a $49 AC tune-up offer generating leads at $36 each with a 30% close rate.

The tune-up is your funnel top. Technician conversion rate benchmarks from ACCA suggest aiming for a minimum 25% close rate from service calls to plan sign-ups. If your techs aren’t pitching the plan on every visit, you’re running a marketing campaign with a broken close.

Check out how to structure technician-generated leads if your team isn’t doing this consistently. Once someone books, your follow-up speed matters more than most contractors realize - the five-minute speed-to-lead rule applies to inbound maintenance inquiries just as much as emergency calls.

How Do You Keep Maintenance Plan Members from Canceling?

A renewal rate below 70% is a warning sign. Something is broken - service quality, communication, or pricing misalignment.

Top-performing HVAC companies with dedicated retention workflows hit 90% renewal rates year over year. Automated reminders are the foundation. Set up renewal reminders at 60 days, 30 days, and 7 days before expiration.

If you’re using ServiceTitan, the marketing automation features inside ServiceTitan Marketing Pro are built for exactly this workflow. SMS outperforms email for renewal reminders in every contractor market we’ve tracked, and SMS and text message marketing for contractors breaks down open rates and response benchmarks if you want to build that sequence properly.

For customers who don’t renew automatically, a personal call from your office manager closes the gap. This isn’t complicated. It’s just follow-through.

Amber DeLong, VP of DeLong and Sons HVAC in Shoemakersville, Pennsylvania, grew her company from a two-person operation to a 10-person team serving over 1,000 customers in just a few years. That kind of growth doesn’t happen by chasing one-time repair calls. It happens by building a recurring customer base and keeping them.

What Maintenance Plans Do for Your Business Valuation

This one doesn’t get talked about enough.

Rosone put it bluntly in his BuildOps interview: “The value of the business IS the maintenance contract base. If I see that a potential acquisition has $10 million of revenue in one-off repair projects last year, that provides me no reassurance that I could expect similar revenue this year. On the other hand, if the company has a maintenance contract base of $4 million, I can reasonably expect that a majority - 90% - of that revenue will reoccur.”

He also made a comparison that reframes how you should think about margins: “Would you rather have 24% gross margin on $10 million of non-recurring installation work or 40% gross margin on $9 million of recurring service revenue?”

Maintenance plan members generate 2.4x to 3.1x higher customer lifetime value than one-time customers, per 2026 HVAC marketing benchmarks. The average HVAC customer LTV is cited at $15,340 across marketing benchmarks, with FirstPageSage putting it as high as $47,200 when full customer lifecycle revenue is counted.

If you ever plan to sell your business, your contract base is what buyers pay a premium for. One contractor BDR documented used data-driven maintenance scheduling to shift work into slower periods and generated an additional $250,000 in revenue and $55,000 in gross profit from that shift alone.

That’s not a marketing win. That’s a systems win. And it starts with having a contract base large enough to schedule around. If your slow season marketing strategy currently consists of running more ads and hoping for the best, a maintenance plan program is the structural fix underneath all of it.

Frequently Asked Questions

How much should I charge for an HVAC maintenance plan in 2026?

According to BDR’s 2026 HVAC Industry Trends report, the average professional maintenance agreement is priced at $225 per year. The full residential range runs $150 - $500 per year, with higher pricing for multi-system homes or indoor air quality add-ons per Housecall Pro’s 2026 pricing data. Price based on your actual loaded costs - labor, drive time, overhead, and consumables - not what the competitor down the street charges.

How do maintenance agreements help fill the slow season?

Maintenance agreements let you proactively schedule tune-ups and check-ins during months when the phone isn’t ringing. BDR documented one contractor who generated an additional $250,000 in revenue and $55,000 in gross profit by shifting maintenance visits into slower periods. The plan base gives you a controllable revenue stream instead of a revenue gap.

What conversion rate should my technicians aim for when selling plans on service calls?

ACCA benchmarks suggest a minimum 25% conversion rate from service calls to maintenance agreement sign-ups. If your techs are closing below that, the issue is usually a lack of a consistent pitch and no structured follow-up. Training your CSRs to reinforce the offer when booking return visits also closes a significant portion of the gap.

How do I keep maintenance plan customers from canceling?

The industry benchmark for renewal rates is 70 - 80% minimum, with top-performing companies hitting 90% through automated renewal workflows and personal outreach. A renewal rate below 70% signals a problem with service quality, communication, or pricing. Automated SMS reminders starting 60 days before renewal expiration outperform email for getting customers to re-commit.

Is it really cheaper to sell plans to past customers than to find new leads?

Yes, by a wide margin. Past customers cost 60% less to convert than new leads acquired through paid advertising, based on contractor marketing benchmarks. With Google Ads maintenance leads running $35 - $75 each according to BaaDigi’s 2024 - 2026 campaign data, your existing database is almost always the highest-ROI place to start a maintenance plan growth push.
