Sound Familiar?
Every HVAC contractor we talk to is dealing with the same problems.
Missed calls, lost jobs
Phone rings while you're in an attic or on a roof. By the time you check, they already called the next company on Google.
After-hours calls go nowhere
A homeowner's AC dies at 10 PM in July. They get your voicemail. You wake up to a missed opportunity worth $800+.
Your CSR is maxed out
Summer hits, phones are ringing off the hook. Your one CSR is juggling five calls. Customers sit on hold. Some never call back.
Paying for leads you never answer
You're spending on Google Ads and LSAs, but half those leads go to voicemail. That's money down the drain.
What If Every Call Got Answered?
ReliAbuild AI is a voice agent that answers your phone, talks to your customers like a real person, and books jobs directly on your board.
It's Friday Night. You're Off the Clock.
A homeowner's AC just died. It's 95 degrees inside. Her kids can't sleep. She Googles "emergency HVAC near me" and calls your number.
You don't hear it ring. You don't have to. Watch what happens next.
Imagine checking your board tomorrow morning, and there's already a $900 emergency job booked, a tech assigned, and the customer confirmed. That's what this looks like.
