How an HVAC Company Tripled Revenue from $400K to $1.2M in 18 Months (Without Hiring More Techs)
Mike's HVAC company was stuck at $400K for 3 years. He was working 70 hours/week and making less than his techs. Here's how we built a retention machine that tripled his revenue.
How an HVAC Company Tripled Revenue from $400K to $1.2M in 18 Months (Without Hiring More Techs)
Mike's HVAC company was stuck.
Same revenue for 3 years straight: $400K/year
Hours worked per week: 70+
Take-home pay: Less than his techs
Customer repeat rate: 11%
He was trapped in the service business hamster wheel:
- Work all day installing and repairing systems
- Spend nights doing estimates and paperwork
- Wake up and do it again
- Never get ahead
Sound familiar?
18 months later, here's where Mike's business is:
- $1.2M annual revenue (+193%)
- $240K recurring revenue (didn't exist before)
- 68% repeat customer rate (up from 11%)
- 30 hours/week (down from 70)
- Customer lifetime value: $2,850 (up from $485)
We didn't hire more techs. We didn't expand to new cities. We didn't even increase prices.
We built a retention machine that turned one-time customers into lifetime clients.
Here's the playbook.
The Problem: Feast or Famine Revenue
When Mike called me, he was frustrated.
"I'm working 70-hour weeks, and I'm making less than my lead tech. What am I doing wrong?"
I asked to see his numbers:
Annual Revenue: $410,000
Breakdown:
- New AC installations: $180K (44%)
- Emergency repairs: $140K (34%)
- Maintenance calls: $90K (22%)
Customer Metrics:
- Total customers served: 845
- Repeat customers: 93 (11%)
- Average transaction: $485
- Customer lifetime value: $485 (same as first transaction)
The diagnosis was clear: Mike had a transaction business, not a relationship business.
Every dollar required:
- Finding a new customer
- Selling them once
- Never seeing them again (89% of the time)
- Starting over tomorrow
The Fatal Flaw: No Retention Strategy
Mike's business model was broken:
How Most HVAC Companies Operate:
- Customer's AC breaks
- They call you (or a competitor)
- You fix it for $200-500
- They disappear
- Next year, their AC breaks again
- They call whoever answers first
- You lost them
The Math Problem:
At 11% repeat rate, Mike needed to find 750 new customers every year just to maintain $400K revenue.
Customer Acquisition Cost (CAC): $85 per customer
Annual marketing spend: $63,750
Profit margin after CAC: 12%
He was spending $63K/year to stay flat.
The Three Missing Pieces
After analyzing Mike's business for two weeks, I found three critical gaps:
Gap #1: No Recurring Revenue
Mike had ZERO recurring revenue. Every dollar was transactional.
The problem:
- Revenue resets to $0 every January 1st
- Completely dependent on weather (hot summers = good year, mild summers = bad year)
- No predictability, no stability, no sleep
Gap #2: No Customer Relationship System
Mike had no way to stay in touch with customers after the job was done.
He had:
- No email list
- No CRM
- No follow-up system
- No maintenance reminders
- No reason for customers to remember him
Out of sight = out of mind = out of business
Gap #3: No Lifetime Value Strategy
Mike treated every customer like a one-time transaction.
He never:
- Offered maintenance plans
- Followed up after service
- Educated customers on preventive care
- Built relationships
- Created reasons to come back
He was leaving 89% of his potential revenue on the table.
The Solution: Build a Retention Machine
We rebuilt Mike's business around one core principle:
"It's easier to keep a customer than find a new one."
We implemented a three-part retention system:
Part 1: Membership Program
We created a tiered maintenance membership program that turned one-time customers into recurring revenue.
The offer:
- Annual maintenance visits (2x per year)
- Priority emergency service
- Discounts on repairs
- No diagnostic fees
- Extended warranties
Three tiers:
- Basic: $199/year (1 visit, 10% off repairs)
- Plus: $349/year (2 visits, 15% off repairs, priority service)
- Premium: $599/year (2 visits, 20% off repairs, priority service, extended warranty)
Part 2: Customer Retention System
We built a comprehensive follow-up and relationship system that kept Mike top-of-mind year-round.
The system included:
- Automated email sequences
- Seasonal maintenance reminders
- Educational content (how to extend AC life, energy-saving tips)
- Birthday and anniversary offers
- Referral incentives
Part 3: Lifetime Value Optimization
We restructured Mike's entire sales process to focus on customer lifetime value instead of transaction size.
Key changes:
- Every service call included a membership offer
- Techs were trained on value-based selling
- Follow-up system to convert one-time customers
- Referral program to leverage happy customers
The Results: $400K → $1.2M in 18 Months
Here's what happened when we shifted from transactions to relationships:
💰 Annual Revenue: $410K → $1.2M (+193%)
🔁 Recurring Revenue: $0 → $240K/year (NEW)
🎯 Repeat Customer Rate: 11% → 68% (+518%)
💎 Customer Lifetime Value: $485 → $2,850 (+488%)
📊 Marketing Spend: $63,750 → $48,000 (-25%)
⏰ Mike's Hours/Week: 70 → 30 (-57%)
✅ Profit Margin: 12% → 31% (+158%)
The best part?
Mike now has $240K in predictable recurring revenue that hits his bank account every year whether he works or not.
