It's June. You've been slammed with AC repair calls since May. You took 180 leads this spring. Now you're overwhelmed and you're losing track of people.
Fast forward to September. The heat breaks. Calls dry up. You're back at the office looking at your CRM and realize: you have 847 leads from the last 6 months that you never followed up with.
These aren't cold leads from ads. These are people who called YOU, got your voicemail, or got a quote and then went silent. They were warm. They still are. But you moved on.
Now it's late fall, temperatures are dropping, people's furnaces are failing, and they're calling 3 other HVAC companies because they forgot about you.
This is the HVAC seasonal cycle, and most companies leave 40-60% of their annual revenue on the table because they never reactivate dormant leads.
At an average HVAC service of $2,400, a dormant lead database of 3,000+ uncontacted people over a season = $7.2M+ in potential revenue you're abandoning.
HVAC demand has two peaks per year:
Peak 1 (April–June): AC season. Cooling system failures, tune-ups, replacements.
Peak 2 (October–November): Heating season. Furnace failures, tune-ups, emergency service.
Off-season (July–September, December–March): Low demand. Homeowners aren't thinking about HVAC. Phone volume drops 60-70%.
The problem: HVAC companies stop marketing during off-season. But the off-season is when you should be reaching out to dormant leads with a different message: "Your furnace is 8 years old. Before winter hits, let's make sure it won't fail on you in January."
Leads that were warm in spring are STILL warm in September if you remind them you exist. They're not calling 3 other companies yet — they're not thinking about HVAC at all. You call, you remind them, you lock in the service call.
Standard process: Lead goes dormant = lost forever
Reactivation process: Lead goes dormant = 8-12% reactivation rate within 6 months
That's not an accident. It's timing. It's the message. And it's automation.
HVAC leads cool off (pun intended) in about 2 weeks if you don't follow up. But they stay warm in the database indefinitely if they called you or got a quote.
The reactivation window is 90–180 days after first contact. Here's why:
0–30 days: Homeowner got 2-3 quotes. Decided to wait. They're not ready yet.
30–90 days: Most competitors have forgotten about them. You're top of mind only if you stayed in touch.
90–180 days: Season changes. A new problem surfaces (AC breaks during summer → fall comes → furnace gets attention). They remember the quote you sent. If you ping them now, you win.
180+ days: Still convertible, but requires more touchpoints. Lower conversion but still profitable.
Most HVAC companies contact leads 1–2 times and give up. Smart companies run a 7-message sequence over 180 days.
Day 0 (Original contact): Initial quote or voicemail callback. Nothing happens here — lead goes cold.
Day 30 (Email): "Hi [Name], just checking in on that AC quote we sent. Questions? Reply here or call."
Day 60 (SMS): "Summer's heating up. Ready to get that AC installed? Locked-in pricing for 5 more days → [link]"
Day 90 (Phone): Automated callback or live call: "Season's almost over. If you wait until August, prices go up. Lock in now?"
Day 120 (SMS): "Summer cooling bill too high? AC replacement saves $40-$60/month. Call to schedule inspection."
Day 150 (Email): "Fall's coming. Before temperatures drop, make sure your furnace is ready. Free inspection scheduled?"
Day 180 (SMS + Final Offer): "Last chance: $500 off furnace installation if you book by this weekend. Call now."
Companies that run this sequence close 8–12% of dormant leads. Companies that don't close 0.5%.
Not all dormant leads are created equal. Segment your database:
Warm Leads (Contacted 30-90 days ago): Recent contact, got quote, just haven't decided yet. Sequence starts immediately. High conversion (10-15%).
Lukewarm Leads (Contacted 90-180 days ago): Old contact, may have moved on to competitor. Need more touchpoints. Moderate conversion (6-8%).
Cold Leads (6+ months old): Stale contact. Conversation required before sequence. Lower conversion (2-3%) but still profitable given cost is near-zero.
Your CRM should automatically segment these based on last contact date. Warm leads get the aggressive 7-message sequence. Cold leads get a 3-message "re-engagement" sequence first.
A Nashville HVAC company tested lead reactivation:
The payback period is so short because you're not paying for ads. You already have these leads in your CRM. You're just reaching back out with automation. The cost is literally the SMS platform subscription ($150/month covers unlimited sends to your database).
Step 1: Audit Your Lead Database
Export your CRM. Segment leads by last contact date. Count warm/lukewarm/cold. This tells you the potential revenue pool ($7.2M from 3,000 leads × $2,400 average = potential if 100% converted).
Step 2: Choose a Reactivation Platform
GoHighLevel, Twilio, or native CRM SMS integration. You need: SMS automation, email, optional voice call broadcast. Cost: $150-300/month.
Step 3: Build Your Sequence Templates
Create message templates for each of the 7 touchpoints. Test subject lines and SMS copy. Example SMS: "Your furnace is [age] years old. Call today for a free inspection before winter hits → [phone]"
Step 4: Segment and Automate
Set rule: If last contact date is 30–90 days ago, start warm sequence. If 90–180 days ago, start lukewarm sequence. If 6+ months ago, start re-engagement first.
Step 5: Track Conversions
Tag reactivated leads in your CRM when they convert. Measure conversion rate by segment. This tells you what's working.
Step 6: Run Year-Round
Reactivation isn't a one-time campaign. It's ongoing. Leads enter the database daily. Old leads cycle through sequences monthly. Set it and forget it.
SMS & Email Automation: GoHighLevel ($99-297/month), Twilio (pay-per-message), native CRM (HubSpot, Pipedrive)
Phone Automation (optional): CallRail, RingCentral
CRM Integration: Zapier or native API to sync reactivation data back to CRM
Total stack cost: $150-300/month. Payback from reactivation: typically 1-3 hours.
Start with your warm leads (30-90 days old). Pull a list of 500 and test the 7-message sequence over 6 months. Measure conversion rate. If you hit 8%+, you've found a revenue stream that requires zero new customer acquisition cost.
Most HVAC companies spend 70% of their budget on ads to get new leads. Meanwhile, they're ignoring 3,000+ dormant leads in their database that are 10x cheaper to convert.
Reactivation fills the seasonal off-season gaps. It smooths revenue. It turns a seasonal business into a year-round business.
The revenue is sitting in your CRM right now. Just reach back out.
Dormant leads aren't dead leads. They're just waiting for the right message at the right time. Automate that message, and watch the revenue flow.
