Recurring revenue from maintenance agreements is one of the biggest drivers of value in an HVAC, plumbing, or electrical company. Here's why buyers pay more for it and how to build it.
Quick answer: Maintenance agreements raise the value of a trades business because they turn unpredictable demand into revenue a buyer can count on. One 2026 industry analysis says the valuation gap between a demand-only shop and one with strong service plans can be two to three turns of EBITDA at the same revenue. Buyers often look for 20% or more of revenue from plans or contracts.
Walk any trades owner through his yard and he'll show you the trucks.
New wrap. New ladder racks. Fully stocked.
Great. A buyer will put a value on those trucks, minus depreciation, and move on in about four minutes.
Then they'll spend four hours on your maintenance agreements.
Why recurring revenue changes the math
A demand-only shop lives and dies by the weather, the phone, and the ad budget. Every January, revenue starts at zero.
A shop with a deep membership base starts every year with money already promised. That's what a buyer is really paying for: certainty.
One 2026 analysis of private equity in HVAC puts the gap at two to three turns of EBITDA between a demand-only shop and a plan-attached shop with the same revenue. It also cites 20% or more of revenue from maintenance plans or commercial contracts as a common buyer threshold.
Do the illustration math. On $1 million of EBITDA, two extra turns is $2 million more at the closing table. Same trucks. Same techs. Different story.
It's not just an HVAC thing
- HVAC: twice-a-year tune-ups, priority service, and discounts on repairs.
- Plumbing: annual whole-home inspections, water heater flushes, and drain maintenance.
- Electrical: panel and safety inspections, surge protection checks, and generator maintenance. In Southwest Florida, generator plans alone can carry a membership program.
- Roofing: annual inspections and maintenance agreements, especially on commercial roofs.
- Pest control, lawn care, and pool service: recurring routes are the business model. Buyers will look hard at route density and how many customers cancel each year.
The 3 mistakes that kill membership programs
- Selling it like an add-on. If the tech mumbles it at the end of the call, it won't sell. It needs a script, a moment, and a reason.
- Not delivering the visits. A plan nobody shows up for is a refund waiting to happen. And a buyer will check your renewal rate.
- Pricing it to break even. The plan should make money on its own and fill your slow season.
The metric that matters
Forget member count for a minute. Track renewal rate.
A thousand members who don't renew is just a busy year. Five hundred who renew year after year is an asset.
In my own coaching practice, I analyzed nearly 9,700 sessions. 82% of the clients who left never told me why. They just stopped showing up. Your maintenance customers are no different. Most won't call to cancel. They'll quietly not renew, and you won't know until the revenue is gone.
The move
Pull three numbers this week: active agreements, renewal rate, and the share of total revenue they drive. That's your recurring revenue baseline. Everything else builds from there.
FAQ
Do maintenance agreements increase the value of an HVAC business? Yes. They create predictable recurring revenue, which buyers value more than one-time service or install revenue. One 2026 industry analysis estimates a gap of two to three turns of EBITDA between demand-only and plan-attached shops of similar size.
What percentage of revenue should come from maintenance agreements? One 2026 analysis of private equity buyers cites 20% or more of revenue from maintenance plans or commercial contracts as a common threshold. Renewal rate matters as much as the percentage.
Can other trades besides HVAC sell maintenance plans? Yes. Plumbers can offer annual inspections, water heater flushes, and drain service. Electricians can offer panel and safety inspections and generator maintenance plans. Roofers can sell annual inspections, and pest control, lawn, and pool companies already run on recurring routes.
