When the AC quits during a Louisville heat wave, your phone can't.
Callbook is the AI receptionist built for Louisville HVAC contractors. It answers every call 24/7 in English and Spanish, asks the right questions, triages emergencies, and books the job or estimate straight onto your calendar — then texts you a summary. Flat $79/month, no contract, live in about a day. Keep your number.
Why a missed call costs a Louisville HVAC contractor the job
Louisville sits in the Ohio Valley, where summers are hot and brutally humid and winters swing cold — so HVAC demand spikes hard and fast. When a July heat advisory rolls in and condensers start failing across the Highlands, St. Matthews, and Jeffersontown, homeowners aren't leaving voicemails; they call the next contractor on the list. The same thing happens in a January cold snap when furnaces give out in the older housing stock around Germantown and Crescent Hill, or after a line of storms knocks out power and floods systems in Middletown. A lot of these calls land after hours, mid-job, or while you're up on a rooftop unit and can't grab the phone. Every one that goes unanswered is a same-day install or a profitable estimate handed to a competitor. Callbook answers all of it — day, night, weekend, peak season — so a ringing phone never turns into a lost customer.
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-AC and no-heat emergencies
When a caller says the AC died in a heat wave or the furnace quit overnight, Callbook recognizes the urgency, asks the right HVAC questions, flags it as priority, and texts you a summary right away so you can respond fast.
Answers in English and Spanish
Every call is handled fluently in both languages, so Spanish-speaking homeowners across Louisville get booked instead of hung up on. No second number, no translation line.
Books straight onto your calendar
Callbook schedules the service call or estimate directly into Google Calendar, Jobber, Housecall Pro, or ServiceTitan, so the appointment is locked in by the time you check your phone.
Works 24/7 through peak season
Heat waves, cold snaps, weekends, and after-hours — Callbook never stops answering. Keep your existing number; calls just stop going to voicemail.

Why Louisville shops pick Callbook
Built for Louisville's brutal cooling season
When Ohio Valley humidity pushes the heat index up and AC systems quit across the Highlands and St. Matthews, calls flood in all at once. Callbook answers every one, triages which are true no-cooling emergencies, and gets them on your schedule before they call the next contractor.
Covers the winter furnace rush too
Louisville's cold snaps hit the older homes around Germantown, Crescent Hill, and Clifton hardest, where aging furnaces fail on the coldest nights. Callbook works 24/7, so a midnight no-heat call in January becomes a booked job instead of a missed voicemail.
Serves the whole metro and beyond
From Jeffersontown and Middletown to Fern Creek, Okolona, and across the river into Southern Indiana, Callbook captures calls from every corner of your service area and books them onto your calendar — no matter where you're working that day.
Reaches Louisville's Spanish-speaking homeowners
With a growing Hispanic community across south Louisville and beyond, Callbook answers fluently in Spanish as well as English. You book jobs from customers other contractors lose at hello — no bilingual office staff required.
Simple, flat pricing
