When Tim Dunn started HVAC Growth Hub, he wasn’t just thinking about lead generation he was thinking about all the money HVAC contractors were leaving on the table.

Tim had seen it firsthand. Contractors would spend thousands to get the phone ringing, only to miss 40–60% of calls because they were on job sites, driving, or closed for the night.

Even when they did answer, valuable time got wasted on unqualified leads asking for “ballpark prices” or “maybe later” appointments.

That’s when Tim had the idea:

What if every HVAC company had a 24/7 voice secretary that never missed a call, qualified leads on the spot, and only sent salespeople the ones worth their time?

The Solution

Tim partnered with tech specialists to build what became known as the A.I. Voice Secretary

Here’s what it does:

Answers inbound calls instantly (under 3 rings).

Calls new leads automatically within minutes of them filling out a form.

Qualifies prospects using proven HVAC questions: budget, timeline, urgency, and decision-maker.

Live transfers hot leads directly to sales reps in the field.

Handles customer support calls, routing them to the right person.

Books call-backs and appointments directly into the company calendar.

Sends an automatic summary of every call to the business owner and office manager, so nothing gets lost.

Tim’s Vision

Tim explains it best:

“Most HVAC owners think their problem is marketing. In reality, they’re already sitting on more leads than they realize they just don’t have the systems to capture and convert them. That’s why we built the A.I. Voice Secretary. It’s like hiring a full-time office assistant, sales rep, and dispatcher but it works 24/7 and never drops the ball.”
