The house is 90°.
The phone keeps ringing.
SiteLine answers both.
Built for solo and small-shop HVAC contractors: AI estimates and automatic SMS lead follow-up for $29/mo, plus an optional 24/7 AI phone receptionist that captures and books service calls for $96/mo total — so a no-cooling call in a heat wave never goes to the next contractor because you were brazing a line set on a rooftop.
Built for HVAC contractors working Chula Vista and San Diego County.
If you run an HVAC shop in Chula Vista, you already know the calls cluster exactly when you have the least time to answer them. Chula Vista runs warm inland — from western Chula Vista out to Otay Ranch, EastLake, Rancho del Rey, and Bonita — so a late-summer heat wave can turn a normal week into a flood of no-cooling calls overnight. The housing splits between older western homes with aging furnaces and little or no AC, and the large master-planned east communities where newer construction drives heat-pump and high-efficiency changeout work under Title 24. The homeowner sweating it out books the first contractor who actually picks up.
The no-cooling-in-a-heat-wave problem.
HVAC is almost never a casual purchase. When the AC quits during a heat wave, the furnace won't light on a cold morning, or there's a gas smell at the unit, the homeowner isn't shopping — they're uncomfortable and worried. They book the first licensed contractor who actually picks up the phone.
That's exactly the moment most independent HVAC contractors can't answer. You're on a rooftop unit, your hands are on a line set, you're in a 130° attic with an air handler, it's after hours, or you can't hear the phone over a recovery machine. The call rolls to voicemail — and most callers won't leave one. They dial the next contractor in the search results. You never learn the job existed.
The fix isn't longer hours or a $300–$600/mo generic answering service whose operators can't tell a condenser from a coil. It's making sure every call gets answered, every lead gets a follow-up text, and every estimate goes out before the customer cools off — figuratively and literally. That's the whole job SiteLine was built to do.
A no-cooling call, captured — not missed.
A scenario HVAC contractors live every summer. Here is how it runs with SiteLine working in the background.

What is one missed Chula Vista call actually worth?
A changeout is a five-figure ticket, and heat-wave calls come in bunches. Use the free calculator to estimate what missed calls cost your HVAC shop in a year. Every number is yours to adjust.

HVAC contractors in Chula Vista — questions, answered.
What's the best scheduling software for a solo HVAC contractor?
The right fit lives on your phone in the field and keeps leads from slipping while your hands are full. SiteLine combines a lead tracker, AI estimate generator, and automatic SMS follow-up at $29/mo, with an optional 24/7 AI phone receptionist in the $96/mo bundle. The free plan covers the estimate builder, materials calculator, checklists, and license tracker forever.
How do I stop missing service calls during a heat wave?
With the Pro + Receptionist bundle ($96/mo), an AI receptionist answers live, captures the job details and how urgent the loss of cooling or heat is, and texts you a summary — and if a call is ever missed, SiteLine texts the caller back in under 10 seconds. On Pro alone ($29/mo), SiteLine runs SMS follow-up on every lead that reaches you. When every shop in town is slammed, being the one who answers wins the job.
What about real emergencies — a gas smell, carbon monoxide, or no cooling for a vulnerable person?
The receptionist is set up to flag words like "gas smell," "carbon monoxide," "no heat," or "no cooling" as urgent and alert you immediately with the call details. It is not an emergency service: anyone in immediate danger — a gas leak or suspected CO exposure — should leave and call 911 and their gas utility (SDG&E). SiteLine helps you respond fast; it does not replace emergency response.
Can SiteLine write an HVAC estimate?
Yes. Describe the job from your phone — AC changeout, furnace replacement, heat pump, mini-split, ductwork, tune-up — and SiteLine drafts a professional itemized estimate to send while you're still on-site. AI estimates are drafts for a licensed HVAC contractor to verify against the current mechanical code and load calculations before presenting to the customer.
Does it work alongside Jobber or Housecall Pro?
Yes. Many HVAC contractors use SiteLine for lead capture, estimates, and the AI phone receptionist, and keep their existing tool for invoicing and dispatch. The receptionist and automatic lead follow-up are the pieces those tools don't offer at any tier.
Do you only serve Chula Vista?
No. SiteLine is software, not a local franchise — it works anywhere in San Diego County and beyond. This page is written for HVAC contractors around Chula Vista because that's a common search, but the product is identical wherever you run your trucks. Permitting and code references vary by jurisdiction; the City of Chula Vista Development Services Department handles mechanical permits in Chula Vista. Also serving HVAC contractors in San Diego and Oceanside.
Is this owned by a private-equity rollup?
No. BizBot Technology LLC is a small US company. Email hello@bizbottech.com and a real person answers. We build for trades operators because the existing tools are either too expensive or not deep enough for a one-truck HVAC shop.
