How Much Revenue Is Your HVAC Business Losing From Dead Leads?

Open your text messages. Scroll back 6 months. Count how many people asked about HVAC service, got a response from you, and then went quiet.

For the average HVAC contractor, that number is 80–150. Most of those people still need HVAC work. They didn't hire your competitor — they just forgot, got busy, or decided to wait. The problem isn't the lead. The problem is the silence.

What Makes a Lead "Dead"

A dead lead is any lead that expressed real interest — asked for a quote, requested a service call, asked about pricing — and then stopped responding. Most contractors categorize these mentally as "lost" once 2 weeks pass without a response.

They're not lost. Research from Forrester and Salesforce consistently shows that 50% of leads that don't convert immediately are eventually ready to buy within 12 months — but only if they're nurtured. Without contact, they'll call whoever reaches them first when they're ready.

Why HVAC Has the Most Dead Lead Potential

HVAC is seasonal. Leads from peak season (July–August, December–January) that didn't convert aren't necessarily gone — they may have handled the immediate problem themselves, called a cousin who knew how to fix it, or simply deferred because their unit limped through the season. Those same systems will fail again. Those customers will need service again.

The HVAC dead lead file is particularly valuable because the leads are pre-qualified (they already know they have an HVAC problem), pre-warmed (they already contacted you specifically), and time-sensitive (HVAC problems don't resolve themselves long-term).

The 30-Day HVAC Dead Lead Re-Engagement Campaign

This is a 3-message sequence sent over 30 days to every unconverted lead from the past 6–18 months.

Message 1 (Day 1): Text or email. "Hi [Name], this is [Your Name] from [Company]. We talked a while back about your [AC/heating/system]. I'm reaching out to a few past leads as we head into [season] — we have some availability coming up and wanted to give priority to people we've already spoken with. Is your system in good shape or is this still something you're looking to address?"

Message 2 (Day 8, only if no response): "Hi [Name], following up quickly — I know you're busy. We're offering a complimentary system check to past customers who haven't booked yet. Let me know if you'd like me to schedule 20 minutes."

Message 3 (Day 22, only if no response): "Hi [Name], final note on this. If your HVAC situation has been handled or you've gone another direction, no problem at all — just reply 'no thanks' and I'll remove you from my list. Otherwise, happy to help whenever the timing works."

How to Build Your Dead Lead List in 30 Minutes

• Go through your texts and identify every person who asked about HVAC service in the last 18 months
• Filter to those who didn't book a job
• Sort by most recent to least recent
• Start with the most recent 50 — these are the highest probability
• Send Message 1 to all 50 on the same day, personalized with their name and what they asked about

At a 15% re-engagement rate on 50 leads, you're looking at 7–8 booked jobs. At $2,800 average job value, that's approximately $20,000 in revenue from a 2-hour exercise.
