How I’d Build a $10M HVAC Business From Scratch

HVAC has one of the best business models in the home services industry. A $300 repair can lead to recurring maintenance revenue and eventually a $10,000 replacement.

But turning that opportunity into a $10 million company requires a plan.

1. Start Lean and Generate Leads

I'd budget $50,000–$100,000 to launch, covering a truck, equipment, licensing, insurance, and working capital. If I weren't a technician, I'd want another $100,000 available for payroll.

Then I'd focus on Google Business Profile, Local Services Ads, and customer reviews.

Every customer goes into a database. Every service call becomes an opportunity to build a long-term relationship.

2. Build Three Revenue Streams

Maintenance: Creates recurring customer touch points and future opportunities.

Service: Generates strong margins through repairs.

Replacement: Produces the big tickets, typically $7,000–$15,000 per system.

The key is building a service and maintenance base that consistently feeds replacements.

3. Scale in Stages

$1M: You're doing everything. The priority is generating enough calls to keep technicians busy.

$3M: Start delegating. You can't answer phones, sell replacements, and manage operations forever.

$3M–$5M: Labor becomes the bottleneck. Track technician performance, develop talent, and build accountability.

$10M: Quality control becomes critical. Callbacks can wipe out the profit from an otherwise successful installation.

4. Prepare for Slow Seasons

July makes everyone look smart. October exposes the weaknesses.

Build maintenance agreements, maintain cash reserves, and keep marketing during slower months. You can't rely on emergency demand year-round.

5. Consider Buying Instead

I've bought five HVAC businesses, and I'd do it again.

I'd look for established customer relationships, maintenance agreements, experienced technicians, strong reviews, and consistent call volume.

But remember, if the owner handles every sale, holds the license, and manages every employee, you might be buying a job rather than a business.
