HVAC Maintenance Agreements: How Profitable Are They Really?

Maintenance agreements are one of those things every HVAC industry consultant tells you to invest in. “Build your agreement base. It’s recurring revenue. Buyers love it.” And there’s truth to that — in theory. But after reviewing hundreds of home services P&Ls at Apex Service Partners, I can tell you that for most HVAC companies, the maintenance agreement program is a small, sometimes barely profitable piece of the business that gets way more attention than it deserves.

That’s not to say agreements are worthless. They serve a purpose. But the gap between how the industry talks about them and what they actually contribute to most contractors’ bottom lines is enormous. Here’s an honest look at the real economics.

What Agreements Actually Look Like for Most Contractors

Walk into the average $3M to $8M residential HVAC company and ask about their maintenance program. You’ll usually find somewhere between 200 and 800 agreements, priced at $150 to $250 per year. That’s $30,000 to $200,000 in annual revenue — which sounds like something until you realize it’s 1% to 4% of total revenue for most companies.

At that scale, agreements aren’t a strategic asset. They’re a side program. And the economics on a per-agreement basis are tighter than most owners realize:

At $50 to $95 of gross profit per agreement, a 500-agreement program is generating $25,000 to $47,500 of gross profit per year. After you factor in the time your CSRs spend selling, scheduling, and managing renewals, the net contribution is modest. For a company doing $5M in total revenue, this isn’t moving the needle.

The “Downstream Revenue” Argument — How Real Is It?

The standard pitch for agreements goes like this: the agreement customer calls you first when something breaks, they’re more likely to approve repairs, and they eventually replace their system through you. So the real value isn’t the $200 per year — it’s the lifetime revenue from each agreement customer.

There’s some truth here, but it’s often overstated. In my experience reviewing real data:

Agreement customers do call you first — but so do most customers who’ve had a good service experience. A satisfied repair customer who isn’t on an agreement will still call you back. The agreement doesn’t create loyalty by itself; good service does.

Replacement conversion is real but hard to attribute. Yes, your maintenance tech might identify an aging system during a tune-up and plant the seed for a replacement. But would that customer have called you anyway when the system failed? In many cases, yes. Attributing the full replacement revenue to the agreement overstates the incremental value.

The retention benefit is genuine but limited. Agreement customers do stick around longer on average. But the churn you’re preventing depends on how competitive your market is and how good your service is. In many markets, the retention difference between agreement and non-agreement customers is smaller than you’d expect.

None of this means agreements are worthless. It means the wildly optimistic “maintenance agreements are the most valuable asset in your business” framing doesn’t match what most contractors actually experience.

When Agreements Actually Matter

There are scenarios where maintenance agreements become genuinely important:

Large-scale commercial contracts. If you service commercial HVAC for office buildings, retail chains, or property management companies, those contracts can represent significant, predictable revenue with real margins. A $50,000 annual commercial maintenance contract is a different animal than a $200 residential tune-up plan.

Very large residential bases (2,000+ agreements). At scale, even modest per-agreement margins add up. A company with 3,000 agreements at $225 each is generating $675,000 in annual revenue. At that point, it’s a real line of business with dedicated staff, optimized routing, and better economics. But most contractors are nowhere near this scale.

Markets with high customer acquisition costs. If you’re spending $300+ to acquire each new customer through Google Ads and LSAs, an agreement that keeps them coming back for 5+ years is a smart retention play. The math works better when the alternative — constantly re-acquiring customers — is expensive.

What Buyers Actually Think About Agreements

Here’s where the industry narrative diverges from reality. Yes, PE buyers will ask about your agreement program. Yes, a large program with strong renewal rates is a positive. But in practice, here’s how it plays out in most acquisitions:

For a typical $5M-$8M HVAC company with 400-800 agreements, the buyer notes the program exists, checks the renewal rate, and moves on. It’s a line item, not a valuation driver. The buyer is far more focused on your gross margins, your service/repair revenue mix, your management team, and your EBITDA trend. Those are the things that actually move multiples.

The companies where agreements genuinely drove a premium multiple were outliers — businesses with 3,000+ agreements representing 20%+ of total revenue. That’s the exception, not the norm. For the vast majority of home services companies, the agreement program doesn’t meaningfully change what a buyer is willing to pay.

Should You Invest in Growing Your Agreement Base?

My honest take: it depends on where else you could put that energy.

If your service department is well-run, your margins are healthy, and you have excess capacity to handle agreement visits without displacing revenue-generating service calls — sure, grow the program. It’s incremental revenue with decent retention benefits.

But if you’re choosing between investing in your agreement program versus improving your service department’s average ticket, hiring another experienced tech, or cleaning up your financial reporting — do those things first. They’ll have a bigger impact on your profitability and your valuation.

The contractors I’ve seen get burned are the ones who poured resources into building an agreement base at the expense of their core operations. They hired agreement salespeople, ran promotions, and drove up agreement counts — but their service margins deteriorated, their techs were stretched thin running low-margin tune-ups, and overall profitability didn’t improve.

If You Do Run an Agreement Program, Track These Numbers

Whether your program is 200 agreements or 2,000, you should know exactly what it’s contributing. The metrics that matter:

If your renewal rate is below 65%, customers are telling you the value proposition doesn’t work at your current price point. Either improve the visit experience or lower the price. If your cost to acquire a new agreement exceeds $75, your sales process is too expensive relative to the return.

The Bottom Line

Maintenance agreements have a place in most HVAC businesses. They provide modest recurring revenue, support customer retention, and create regular touchpoints for identifying repair and replacement opportunities. But they’re not the golden ticket the industry makes them out to be. For most contractors, agreements represent 2-5% of total revenue and contribute modestly to overall profitability.

Focus on what actually drives your business: service call volume, gross margins, technician productivity, and operational efficiency. If your agreement program supports those things — great. If it’s distracting from them, it’s a problem worth fixing.

At Profitability Partners, we help HVAC companies see exactly where their profit comes from — and that often means cutting through the noise about programs that sound good in theory but don’t move the bottom line. If you want an honest look at what’s actually driving your profitability, let’s dig into the numbers together.
