The CallRail alternative built for HVAC companies.

HVAC runs on the two worst weeks of the year: the first hard freeze and the first heat wave, when every phone in town rings at once and a call to voicemail is a same-day job gone to whoever answers first. FieldLine gives your shop a dedicated number per channel and per tech, records and summarizes every call, and turns each ring into a lead card, so you know which ads produced the job and nothing gets lost when it's slammed.

• A no-heat call at 6am with a baby in the house goes to voicemail, and by the time you hear it the homeowner already booked the next company that picked up.
• You run Google LSA in winter and Yelp all year and honestly can't say which one actually rings, so you keep paying for both and guessing.
• Maintenance-plan reminders and warranty callbacks fall through the cracks between the truck and the office, and a signed service agreement quietly goes unrenewed.
• During a heat wave the phone never stops, techs answer on their own cells, and by night nobody can reconstruct who promised what to which customer.

• Attribution stops at the call — there's no built-in lead workflow, follow-up state, or crew view, so a busy shop still tracks callbacks on sticky notes.
• It's a horizontal tool sold to marketers and agencies; the setup, vocabulary, and dashboards aren't home-services-native and assume someone who lives in analytics.
• Base minute allotments (around 250) get consumed quickly, and overages on minutes and extra numbers stack up on a shop that actually rings a lot.

• Attribution plus recorded calls plus automatic lead cards plus crew activity live in one workspace — the whole ring-to-follow-up loop, not just the attribution slice.
• Recording, transcripts, AI summaries, and AI lead extraction are included on every tier instead of being metered add-ons or upsells.
• Two-minute setup in plain operator language, no app to install — calls forward to the phones the crew already carries.

Give each channel its own number, so you can see which of these actually produced jobs — and cut what doesn't.
