AI that keeps your HVAC company booked in both seasons

ServiceHarness is an AI Chief Revenue Officer for heating and cooling companies. Ten AI agents chase every replacement quote until it signs, ask for Google reviews after every call, reactivate past customers into tune-ups between seasons, track whether ChatGPT and Google AI recommend you and fix why not, publish town and cost pages that rank, and chase unpaid invoices. Every message waits for your approval.

Replacements are won twice: first in the answer (the map pack or AI response the homeowner sees when they search "AC replacement near me") and again in the follow-up, because a $4,500–$12,000 quote rarely closes on the first visit. Showing up in the answer and chasing every open quote on a schedule are exactly the two jobs the agents run.

Plans start at $60/month (Starter), with Growth at $100/month and Scale at $200/month. Chat with your AI CRO is unlimited and free on every plan. No setup fee, no contract, and you can grade your business free before signing up.

The same coverage with people (part-time marketing coordinator, local SEO retainer, review service, content writer, follow-up help) runs $5,500–$10,500 a month at market rates. At the $60 entry plan that's $5,440–$10,440 kept monthly, about $65,000–$125,000 a year.

Assistants recommend the HVAC companies that trusted sources document best: consistent directory profiles, recent reviews, and website pages that plainly answer cost and service questions for your towns. ServiceHarness asks the real questions weekly, shows who's being named instead of you, and its Content and SEO agents build the missing pieces.

With the list you already own: last season's customers. A systematic tune-up and maintenance-plan re-ask to past furnace and AC customers fills October and April, and it's the Referral Agent's standing job: 5–10% of past customers book when asked, and almost nobody asks.

In the 26 live packs we measured, ranked businesses carried a median of 41 reviews, 97% listed hours, and leaders held 10+ photos with a median of 67 reviews. The pack rewards continuously maintained profiles, and strong-but-stale is the most common gap: in our August 2026 refresh, 52% of the 198 reviewed businesses we measured had added zero new reviews in ninety days. Fixable upkeep, not a mystery.

It includes one: customers, jobs and quotes live in it, but the difference is that the agents work the database instead of waiting for you to. The open replacement quote gets chased, the past customer gets the tune-up ask, the aging invoice gets a nudge, all drafted for your approval.

No. Every review request, follow-up, and reactivation message is drafted and queued for you first. Approve one at a time, or let message types you trust flow. The default is you see everything.

No. Only 18% of the 66 licensed HVACR contractors in Union County run one (August 2026). The agents start where HVAC calls actually come from: your Google profile, reviews, and follow-up. The Content and SEO agents make a website count when you're ready.

GEO, generative engine optimization, is making sure AI assistants name your company when homeowners ask who should fix or replace their system. ServiceHarness measures it with live weekly questions across ChatGPT, Google AI, Perplexity and Claude, and closes the gaps that keep good companies out of the answers.

From ServiceHarness's own analysis of every licensed home-service contractor in Union County, New Jersey: websites graded, 26 live map packs measured, and AI assistants asked real buyer questions with answers recorded (July 2026). The aggregate queries were re-run in August 2026 across 1,814 tracked businesses, with the HVACR roll broken out. Aggregates only; no individual business identified.
