The Problem

A Dead AC Won't Wait for Voicemail

It's 95 degrees. Their AC just died. They're calling every HVAC company on Google until someone picks up. Will that someone be you?

80%won't leave a voicemail

A homeowner in 95-degree heat isn't leaving a message — they're calling the next HVAC company. Speed to answer wins the job.

40%of revenue is seasonal

Summer and winter spikes mean your phones are slammed when it matters most. One missed call during peak season is $1,500 gone.

62%of calls go unanswered

You're on a roof, in an attic, or driving between installs. Your best leads are calling while your hands are full.

35%of calls come after hours

Furnace dies at 10pm, AC quits on a Saturday. These callers have urgency and budget — and they're calling NOW.

From a Real HVAC Business
Last summer we were missing 8-10 calls a day during the AC rush. Mercvox caught every single one. We booked $18K in new installs in the first month alone — jobs that would have gone to competitors.
