The math nobody adds up

Every missed call is a job your competitor just booked.

When your phone rings and nobody picks up, that customer does not wait. They scroll to the next HVAC company and call them instead. It happens after hours, on weekends, and every time you are elbow-deep in a furnace. You never see the job you lost. You just feel the slow month.

80%

of callers will not leave a voicemail. They just call the next company.

10-25%

of calls the average owner misses while on a job, after hours, or slammed.

$5,000+

the value of a single install you lose every time one of those calls rings out.

Miss twelve calls a month. If only two of them were jobs at $400 each, that is $800 walking out the door, every month. The service that catches them is $497. Everything above one recovered job a month is pure profit you are currently throwing away.

One HVAC company per service area.

We work with a single HVAC business per territory, so you are never competing against another shop running the same system. Once your area is claimed, it is closed. Right now, yours is open.

The results, in their own words.

Rex Automation did excellent and efficient work. They walked me through the technical stuff and guided me at every stage.

Jacky built us a system that analyses every cold call our team makes, grades each rep's performance, and generates a coaching report with specific strengths and weaknesses. Every caller now gets actionable feedback on every call, our outreach quality has improved significantly, and it has run reliably for months.

Working with Jack and his team has been a game changer for our business. Jack is incredibly diligent and takes the time to truly understand the depth of each project. The kind of tedious, repetitive work that used to eat up our team's time is now handled through AI solutions built with real precision. Things we thought would take months to automate, they made totally possible.

We had been burning hours on manual outreach with mediocre results. Within six weeks the system was generating better-qualified meetings than our SDR team ever did.

I've had a great experience working with Rex Automation. They set up multiple automations for my business that have noticeably reduced my workload and saved me time day-to-day. What stood out most was the extra effort they put in behind the scenes to make sure everything runs properly. They don't just set things up and disappear. Overall, a very solid service if you're looking to streamline your operations.

Straight answers.

Does it sound like a robot?

No. It is a natural-sounding voice trained on your business. Most callers cannot tell, and the ones who can do not care, because their problem gets solved and the job gets booked. Call the demo line above and judge for yourself.

What about real emergencies?

True emergencies get routed straight to your cell, 24/7. You set the rules for what counts as urgent and how it reaches you.

Do I have to change my number?

No. You keep your number. Callers notice nothing. We just make sure it is always answered.

What if I miss a call myself while I am slammed?

That is the whole point. It answers the calls you cannot get to, on the truck, after hours, on weekends, when the line is already busy.

How is this different from an answering service like Ruby?

Human services charge by the minute and bill you for overages, mostly during business hours. We are flat, unlimited, and 24/7, and we book the job into your calendar rather than just taking a message.

How fast can I start, and can I cancel?

Live in 24 hours, and we do the entire setup. It is month to month, cancel anytime, with a 14-day free trial and a booked-jobs guarantee on top. The risk is on us.

Your phone is ringing. Let us answer it.

Hear it work in 60 seconds, then start your free trial. Live in 24 hours, and your territory is still open.
