The Challenge

Total Comfort Services offered both HVAC and plumbing services in the Denver metro area—but operated them as two completely separate businesses under one roof. With 9 HVAC technicians and 6 plumbers generating $3.2M annually, they were missing massive revenue opportunities hiding in plain sight.

Owner Rick Thompson knew customers who needed both services, but his systems and processes weren't designed to capitalize on cross-selling. Worse, the two divisions often worked against each other, competing for scheduling priority and resources.

Key Pain Points

Siloed Operations:

  • HVAC and plumbing teams used separate scheduling systems
  • Different phone numbers for each service line
  • No visibility into customer service history across divisions
  • HVAC tech couldn't see customer had plumbing issue (and vice versa)
  • Two separate price books with inconsistent pricing strategies
  • Teams viewed each other as competition, not collaboration

Massive Cross-Selling Opportunity Missed:

Example: Mrs. Johnson calls about AC not cooling
- HVAC tech repairs AC for $350
- Tech notices leaking water heater in garage
- Doesn't mention it (not trained, not tracked, no incentive)
- Customer doesn't know Total Comfort does plumbing
- 3 weeks later: Water heater fails, customer calls competitor
- Lost revenue: $2,400 water heater replacement
  • Estimated 60-70% of customers needed both HVAC and plumbing over 3-year period
  • Cross-sell rate: Only 12% (industry leaders: 40-50%)
  • Millions in lost revenue to competitors

Customer Confusion:

  • "Wait, you do plumbing too? I didn't know that!"
  • Two separate invoices if they used both services
  • Different customer experiences (HVAC professional, plumbing inconsistent)
  • Different payment methods accepted
  • Customers felt like they were dealing with two different companies

Operational Inefficiency:

  • HVAC tech drove past house with pending plumbing job
  • Could have done both same visit (saved 2 hours drive time)
  • Separate dispatch for HVAC and plumbing (should be unified)
  • Duplicate customer calls ("which department do I need?")
  • Scheduling conflicts (HVAC and plumbing crews both scheduled same time)

Lack of Customer Intelligence:

  • No consolidated view of customer equipment and service history
  • HVAC tech couldn't see customer's plumbing history
  • Plumber couldn't see HVAC maintenance agreement status
  • No data on cross-selling opportunities
  • Couldn't identify high-value customers across both divisions

Disconnected Marketing:

  • HVAC marketing budget: $6,000/month
  • Plumbing marketing budget: $4,000/month
  • Total: $10,000/month spent acquiring NEW customers
  • Meanwhile: Existing 1,800 HVAC customers didn't know about plumbing services
  • Existing 900 plumbing customers didn't know about HVAC services

The breaking point: Discovered that 340 HVAC maintenance agreement customers had used competitors for plumbing services in past year. Lost $680,000+ in revenue to competitors while already serving those customers in another capacity.

The Solution

Rick knew the company needed to operate as ONE unified business, not two divisions. After evaluating platforms, he chose ServiceSync for its:

  • Unified customer database across all service lines
  • Cross-selling opportunity identification (AI-powered)
  • Single scheduling system for multiple trades
  • Cross-sell performance tracking
  • Bundled service offerings
  • Unified customer communication

  • Merged 1,800 HVAC customers + 900 plumbing customers into single database
  • Identified 380 customers who had used both services
  • Consolidated service histories across divisions
  • Unified pricing database
  • Created comprehensive customer profiles (all equipment, all services)

Phase 2: Service Line Integration (Weeks 3-4)

  • Unified scheduling system (HVAC and plumbing on one calendar)
  • Single dispatch console (dispatchers see all technicians)
  • Created cross-sell opportunity alerts (AI identifies opportunities)

Phase 4: Bundled Offerings (Weeks 7-8)

  • Created "Total Comfort" maintenance agreement (HVAC + plumbing)
  • Developed bundle pricing (10-15% discount vs. separate services)
  • Built package offerings (AC + water heater, furnace + drain cleaning, etc.)
  • Launched "Whole Home Protection Plan"

Phase 5: Team Alignment (Weeks 9-10)

  • Joint team meetings (HVAC and plumbing together)
  • Shared commission structure for cross-sells
  • Cross-training program (HVAC techs learn basic plumbing, vice versa)
  • Unified branding and messaging
  • Created "One Team" culture

Phase 6: Marketing Integration (Weeks 11-12)

  • Rebranded from "Total Comfort HVAC + Total Comfort Plumbing" to "Total Comfort Services"
  • One phone number (system routes to appropriate tech)
  • Unified website emphasizing both services
  • Email campaigns to HVAC customers about plumbing (and vice versa)
  • Cross-promotional truck branding

Total implementation time: 12 weeks

The Results

Revenue Per Customer Explosion: +156%

Before ServiceSync:

  • Average HVAC customer lifetime revenue: $1,650
  • Average plumbing customer lifetime revenue: $1,250
  • Combined average (all customers): $1,850
  • Cross-sell rate: 12%

After ServiceSync (12 months):

  • Average customer lifetime revenue: $4,740 (first year)
  • Projected 3-year LTV: $6,920
  • Cross-sell rate: 43%
  • Increase: 156% in first year, 274% projected over 3 years

Revenue breakdown transformation:

BEFORE (example customer over 3 years):
Year 1: AC repair $380
Year 2: AC tune-up $149
Year 3: Furnace repair $285
Total: $814 (HVAC only, used competitor for plumbing)

AFTER (same customer profile):
Year 1: AC repair $380 + water heater flush $129 + drain cleaning $149 = $658
Year 2: Total Comfort Agreement $599/year = $599
Year 3: Furnace tune-up (included) + water heater replacement $2,400 = $2,400
        + emergency plumbing repair $380 = $2,780
Total: $4,037 (5× higher!)

Cross-Selling Success

Cross-sell conversion rate:

  • Before: 12% (mostly accidental)
  • After: 43% (systematic process)
  • Industry average: 18%
  • Industry leaders: 40-50%

How ServiceSync achieved 43% cross-sell rate:

1. AI-powered opportunity identification:

System analyzes customer data and flags opportunities:

Alert: "HVAC Maintenance Customer - No Plumbing Service History"
- Customer: Robert Martinez
- HVAC equipment: 8-year-old furnace + AC (well-maintained)
- Plumbing: No service history
- Opportunity: Water heater likely 8+ years old (due for flush/replacement)
- Recommended action: During next HVAC visit, technician inspects water heater

Result: Sold $135 water heater flush + $299 whole-home protection plan

2. In-app cross-sell prompts:

HVAC tech completes AC repair, app shows:

┌────────────────────────────────────────────────┐
│ Cross-Sell Opportunity Identified!             │
├────────────────────────────────────────────────┤

3. "While we're here" bundling:

  • Same-visit cross-sell discount (15-20% off)
  • "Since we're already here, we can check your [other service] for [discounted price]"
  • Convenience + savings = 67% take rate on same-visit offers

4. Maintenance agreement cross-sells:

  • HVAC-only agreement customers pitched "Whole Home Protection" upgrade
  • Included both HVAC and plumbing maintenance
  • Only $20/month more than HVAC-only plan
  • 58% of HVAC-only customers upgraded

Results by cross-sell type:

  • HVAC → Plumbing cross-sells: 389 customers (Year 1)
  • Plumbing → HVAC cross-sells: 156 customers (Year 1)
  • Total new cross-sells: 545 customers
  • Average cross-sell value: $840 first transaction
  • Ongoing maintenance revenue: $299-599/year per cross-sell customer

Average Ticket Increase: +113%

Before ServiceSync:

  • Average HVAC ticket: $385
  • Average plumbing ticket: $425
  • Overall average: $420

After ServiceSync:

  • Average ticket (single service): $485 (+15% through better upselling)
  • Average ticket (cross-sell same visit): $1,240
  • Average ticket (bundled maintenance agreement): $2,150
  • Overall average: $895 (+113%)

Why tickets increased:

  1. Same-visit bundling (high take-rate due to convenience)
  2. Comprehensive proposals (3-option quoting with bundles)
  3. Maintenance agreements (annual pre-pay increased average transaction)
  4. Equipment replacement bundles (AC + water heater package deals)

Operational Efficiency: +38%

Route optimization across both divisions:

  • Before: HVAC tech drives past house with plumbing job, plumber visits separately
  • After: System identifies same-street jobs, assigns both to one visit if possible

Efficiency gains:

  • Drive time reduced 22% (smarter routing)
  • "While we're here" jobs (reduced truck rolls)
  • Cross-trained techs can handle simple issues in both trades
  • Unified dispatch reduced scheduling conflicts

Example scenario:

OLD WAY:
- Monday 2 PM: HVAC tech repairs AC at 1234 Oak St
- Wednesday 10 AM: Plumber fixes leak at 1238 Oak St (2 houses away)
- Total drive time: 2.5 hours (2 trips from office)
- Customer convenience: Two separate appointments

NEW WAY:
- Monday 2 PM: HVAC tech repairs AC at 1234 Oak St
- System alerts: "Plumbing job at 1238 Oak St pending"
- Dispatch assigns plumber to same afternoon route
- Monday 3:30 PM: Plumber handles leak at 1238 Oak St
- Total drive time: 1.3 hours (one trip, both jobs)
- Saved: 1.2 hours (48% reduction)

Impact over 12 months:

  • 1,840 combined service visits (saved significant drive time)
  • Estimated 960 hours saved across all technicians
  • 960 hours × $45/hour = $43,200 in recovered productivity
  • Reinvested in additional service capacity

Customer Lifetime Value: +274%

LTV calculation:

Before ServiceSync (HVAC customer):

Year 1: $450 (1-2 service calls)
Year 2: $380 (1 service call)
Year 3: $520 (1-2 service calls)
Total 3-year LTV: $1,350
Retention rate: 58%

After ServiceSync (Total Comfort customer with cross-sells):

Year 1: $1,850 (HVAC + plumbing services)
Year 2: $2,240 (maintenance agreement + add-on services)
Year 3: $2,830 (equipment replacement + ongoing maintenance)
Total 3-year LTV: $6,920
Retention rate: 89%

Increase: 413% higher LTV

Why LTV increased dramatically:

  1. More services = more touchpoints = stronger relationship
  2. Maintenance agreements = predictable recurring revenue
  3. Higher retention (89% vs. 58%) = longer customer relationships
  4. Higher spend per year ($2,307 vs. $617 average)
  5. Equipment replacement bundles (AC + water heater together)

Customer Retention: 89%

Retention by customer type:

  • HVAC-only customers: 61% retention
  • Plumbing-only customers: 54% retention
  • Cross-sell customers (use both services): 89% retention
  • Maintenance agreement customers (both trades): 94% retention

Why multi-service customers stay:

  • More frequent touchpoints (4-8 visits/year vs. 1-2)
  • Higher perceived value ("they handle everything")
  • Convenience (one company for multiple needs)
  • Relationship depth (know the technicians)
  • Switching costs (would need to find TWO new providers)

Any technician (HVAC or plumbing) sees complete picture

2. Cross-Sell Opportunity Engine

AI identifies opportunities based on:

  • Service history gaps (HVAC customer, no plumbing service)
  • Equipment age (7+ year water heater = flush or replace)
  • Seasonal triggers (pre-winter furnace + drain cleaning bundle)
  • Geographic clustering (jobs in same neighborhood)
  • Customer value tier (high-value customers get proactive outreach)

Opportunities presented at perfect moment:

  • During service visit (highest conversion)
  • In follow-up email (automated sequence)
  • Via phone call (office staff for high-value opportunities)

3. Bundled Service Offerings

  • After: "Total Comfort Services - HVAC & Plumbing"
  • Visibility impact: Customers seeing truck knew full service offering

Challenges Overcome

Cultural Resistance Between Divisions

Challenge: HVAC and plumbing teams viewed each other as competition, not collaboration

Solution:

  • Joint team meetings (built relationships)
  • Shared commission structure (aligned incentives)
  • "One team" messaging from owner
  • Celebrated cross-sell successes publicly
  • Team events (bowling, BBQs) to build camaraderie

Outcome: After 6 months, teams actively helped each other

Training Technicians to Recognize Opportunities

Challenge: HVAC techs didn't know plumbing issues, vice versa

Solution:

  • Basic cross-training (8-hour course for each division)
  • Visual guides (photos of common issues to look for)
  • Mobile app prompts (system reminds techs to look)
  • Role-playing practice sessions
  • Ongoing coaching from top performers

Outcome: 82% of technicians actively cross-selling within 3 months

Pricing Strategy for Bundles

Challenge: How to price bundles (discount too much = margins suffer, too little = no appeal)

Solution:

  • Analyzed customer purchase patterns
  • Calculated lifetime value of bundled customers (4× higher)
  • Priced bundles at 10-15% discount vs. separate services
  • Emphasized convenience and value, not just price

Outcome: 412 customers bought Whole Home Protection plan at $599/year

System Integration Complexity

Challenge: Two separate scheduling systems, different processes

Solution:

  • ServiceSync's unified platform replaced both systems
  • 12-week phased implementation (one division at a time)
  • Extensive training and support
  • Dedicated project manager

Outcome: Smooth transition, minimal disruption
