When OKC swings from 100° to an ice storm, your phone shouldn't go to voicemail
Callbook is the AI receptionist that answers every HVAC call 24/7, in English and Spanish. It asks the right triage questions, flags the no-cool and no-heat emergencies, and books the job or estimate straight onto your calendar. Flat $79/month, no contract, live in about a day on your current number.
Why Oklahoma City HVAC contractors can't afford a missed call
Oklahoma City weather doesn't do gradual. A 100-degree July afternoon in Moore can flip to a hard freeze by January, and a single April storm line can hammer outdoor condenser units with hail from Yukon to Midwest City in one evening. When a system quits, homeowners in Edmond and Norman don't leave a voicemail and wait — they scroll to the next contractor and call again. Summer heat advisories and winter cold snaps both create the same crush: dozens of calls landing while your techs are already on a roof or under a house, hands full and phone buzzing. Add the post-storm rush after hail and high winds, and the calls pile up faster than any one person can answer. Every ring you miss after hours, during a service call, or on a Saturday is a job that goes to whoever picked up. Callbook makes sure that's always you — answering instantly, day or night, so the no-cool call in Bethany and the new-install estimate in Deer Creek both get captured.
If Callbook books just one extra job a month, it has already paid for itself several times over.
Most shops miss far more than one call a month.

What your AI receptionist handles
Triages no-cool and no-heat emergencies
When a system is down in a July heatwave or a January freeze, Callbook recognizes the urgency, gathers the details, and flags it as a priority so you can respond before the customer calls someone else.
Answers in English and Spanish
Every caller is greeted and helped in their own language. Callbook switches naturally between English and Spanish so OKC's bilingual households book just as easily as anyone else.
Books the job onto your calendar
Callbook asks the right HVAC questions, then schedules the service call or estimate directly into Google Calendar, Jobber, Housecall Pro, or ServiceTitan — no double-entry.
Texts you a summary of every call
As soon as a call wraps, you get a text with the caller's name, the issue, the neighborhood, and what got booked — so you're up to speed before you ever dial back.

Why Oklahoma City shops pick Callbook
Built for OKC's temperature whiplash
Triple-digit summers and hard winter freezes mean both AC and furnace failures spike, often the same week. Callbook answers every call through both seasons and tags the urgent no-cool and no-heat jobs so you hit them first.
Captures the post-storm surge
After a spring storm line or hail rolls through Moore, Norman, and Midwest City, calls flood in at once. Callbook handles them all in parallel — no busy signal, no voicemail, no caller hanging up to try the next contractor.
Covers the whole metro, day and night
From Edmond and Deer Creek to Yukon, Bethany, and Del City, homeowners expect a fast answer. Callbook works 24/7 so an after-hours emergency in any suburb still books a real appointment instead of going to a competitor.
Serves OKC's Spanish-speaking households
A large share of the metro speaks Spanish at home. Callbook answers fluently in both English and Spanish, so you never lose a job because no one on the line could take the call.
Simple, flat pricing
Questions HVAC contractors ask
How much does Callbook cost?
It's a flat $79 per month with no contract. That includes 250 minutes of calls; if you go over, it's just $0.40 per extra minute. No per-call fees, no setup tiers — one predictable price whether it's a slow week or a post-storm rush.
Can it handle a flood of calls after a storm?
Yes. When a spring storm or heatwave sets the phones off across Moore, Norman, and Midwest City, Callbook answers every call at the same time. No caller gets a busy signal or voicemail, so the surge turns into booked jobs instead of lost ones.
Will it really answer in Spanish?
Yes — Callbook is fully fluent in English and Spanish and switches automatically based on the caller. With OKC's large Spanish-speaking community, that means you capture jobs you'd otherwise miss because no one could take the call.
Does it book onto my existing schedule?
It does. Callbook integrates with Google Calendar, Jobber, Housecall Pro, and ServiceTitan, so appointments land directly on the calendar you already use. You keep your current phone number and you're typically live in about a day.
