Didaxis Group

AI front office for residential HVAC

Your best lead called at 7:30pm. Nobody answered.

Most residential HVAC shops lose more money at the phone than at the invoice. Homeowners pay the day you finish the job, that part is solved. The leak is upstream: after-hours calls that hit voicemail, estimates that sit un-followed-up, and the customer who books whoever calls back first.

Founder-run. No HVAC logos to show you yet, so every number below links to its source, not a testimonial you have to take on faith.

The leak nobody is watching

Residential shops get paid fast. They just do not get booked fast.

The usual advice, fix your slow invoicing and chase your unpaid jobs, is a commercial-contractor problem. In residential, nearly 80% of pros are paid within three days and 48% collect same-day. Cash is not stuck in accounts receivable. It leaks out before the job ever exists.

The after-hours call

Between 45% and 62% of customer calls come outside business hours, and the average shop misses 22 to 27% of the daytime ones too. Voicemail does not save the lead: most callers hang up and dial the next contractor.

The estimate that goes quiet

Only 16% of contractors follow up the same day on an unsold estimate. Most quotes do not lose to price, they lose to silence. And 48% of reps never make a second attempt.

The five-minute window

Answer a web lead within five minutes instead of thirty and you are 21x more likely to qualify it. Yet the average home-service business takes 42 to 47 hours to respond.

The month-13 membership cliff

Around 74% of home-service memberships cancel at first renewal, usually because the tune-up they paid for never got scheduled during the busy season.

The equipment is only half the job.

Your crews handle the units. Didaxis handles everything around them, from the first ring to the final follow-up, so the office keeps pace with the field.

How the layer works

It sits on top of the software you already run.

No rip-and-replace. It overlays ServiceTitan, Housecall Pro, or Jobber, whatever you use, reading open estimates and writing bookings back into your calendar. Your accounting, payroll, and dispatch stay untouched. And it starts read-only: you see everything before a word goes to a customer.

01

Catch every call, day or night

When a call comes in after hours or while you are on a truck, an AI agent answers in your company name, screens out robocalls, triages the emergency, and either books the slot or texts the homeowner back in seconds. No more voicemail black hole.

02

Answer fast enough to win the job

When a web form or missed call lands, a reply goes out in under a minute. Since 78% of home-service buyers hire whoever responds first, speed is the whole game, and it is the one thing a busy office cannot do by hand at 8pm.

03

Follow up on every estimate, automatically

When a quote goes unsold for a day, Didaxis drafts a branded good-better-best recap from the tech's own notes and runs a day 1, day 3, day 7, day 14 sequence over text and email. The follow-up that tanks when you get busy now runs itself.

04

Hand the judgment calls to a person

When something is ambiguous, an angry customer, a warranty question, a big-dollar decision, it routes to a human instead of guessing. During onboarding, nothing customer-facing sends without a person approving it first.

Booked before the season turns.

A tune-up a homeowner paid for is worth nothing if it never gets scheduled. Didaxis fills the maintenance calendar before the busy season buries it, which is where most memberships quietly die.

Measure your own leak

What are missed calls costing you a month?

Three numbers from your own shop. No email required to see the result, the math is yours.

Estimated revenue lost to missed calls, monthly

$0

Uses a conservative 25% booking-to-job rate on recovered calls, the illustrative model from home-services call-handling research. It is a smoke alarm, not an audit. A real number needs your actual call logs, which is what the 15-minute test pulls.

Every number, sourced, and labeled by how much weight it can hold.

Green is an independent study or large third-party survey. Amber is a figure from a vendor that sells this kind of product, directionally useful, but read it knowing who is talking. I would rather show you the difference than blur it.

The 15-minute leak test

Find out what your phone and your open estimates are really costing you.

I will run two tests on your own shop: a 7:30pm call to your main line, and a 6:30pm form submission on your site. Then we pull your last 20 completed jobs and open quotes. You get a number. Hire me only if it is big enough to bother.
