Refrigerant tracking on autopilot. Maintenance plan renewal that runs itself. Marketing intelligence ServiceTitan can't match — at one flat monthly fee, not per tech.
Section 608 logs are required — and the AIM Act drop to 15 lbs (Jan 1, 2026) just expanded the systems you have to track by ~70%. Tech snaps two photos and a voice note. AI reads the cylinder type and weight, the system plate, and your tech ID, drafts a compliant entry covering all the required fields, ties it to the job, and files it in your EPA-ready archive. Audit-ready records — without anyone keeping a paper logbook.
| Date, technician name + 608 cert # | Pulled from the tech's profile — never re-typed |
| Refrigerant type + amount added/recovered | From cylinder photo + tech voice note |
| Appliance ID + system charge spec | From equipment plate photo |
| Leak inspection method + leak rate | Tech selects method (electronic / UV / bubble); rate calc'd from history |
| Repair verification + year-end EPA summary | Logged with retest results; full compliance report on demand |
AI drafts. The certified tech reviews and confirms (with their 608 cert # and timestamp) before any entry is saved to the official log. If the AI can't read a plate cleanly, the tech taps in the missing field — never blocks the job.
ServiceTitan integrates with a third-party tracker (RefriTrak). None of them draft the log entry from a photo + voice.
Tune-up plans are the holy grail — $200–$400/yr per home, signed once, billed forever. Most shops sell them sporadically because nobody has time to chase renewals. We don't chase. We know when each system was installed, when it was last serviced, what the LA weather is doing this week, and we draft the renewal email in your shop's voice automatically. You hit "send" — the recurring revenue takes care of itself.
Lead → diagnostic visit → quote → schedule → install or service → photos → invoice → maintenance plan → follow-up. Every step flows into the next on its own. You enter a job once; the system carries it from there. Less typing, less remembering, more brain space for the actual work. And the code and data are yours, day one and day one thousand.
I know a contractor out of state who wanted to modernize his business — get the AI working, fix the marketing, automate the office. He didn't have time to learn it himself, so he brought on a partner who did. The partner now runs the office, the systems, the AI side. He's still in the field. They split the company 50/50.
That's the modern playbook for getting your business ahead — give up half of it, forever, to a partner who handles the tech side. Hausstack is the third option. We do the tech partner's job. You don't give up a single point of equity.
| Path to a modern HVAC business | Annual cost | What you give up |
|---|---|---|
| 50/50 tech partner | $0 cash | 50% of every dollar — forever |
| ServiceTitan at 5 trucks ($300–$500/tech)* | $18K–$30K/yr + $5K–$50K implementation | Per-tech pricing punishes growth |
| Hire office manager + marketer + maintenance coordinator | $180K–$260K/yr + benefits | Time, cash, focus |
| Hausstack | ~$28K year 1, ~$18K/yr after | Nothing. Code & data are yours. |
Hausstack runs about 1% of a typical LA HVAC contractor's annual revenue. Half your business is half of it. There's no comparison.
Because the system is built around how your shop actually runs, there's nothing weird to memorize. It looks like how you already work — just faster. Less time training new hires. Fewer "where do I click?" calls in the middle of a service call.
ServiceTitan scales the bill every time you hire. We don't. And we do things ServiceTitan can't do at any price.

*ServiceTitan public pricing isn't posted; ranges from third-party trackers (Apr 2026). EPA Section 608 violations carry penalties of $44K–$70K per day per violation. Pays for itself the first time you avoid one, the first quarter you stop missing maintenance plan renewals, and every new truck after #5. The first call is honest, no pressure — we'll only build it if it makes sense for your shop.
Whatever you're on today — ServiceTitan, FieldEdge, Housecall Pro, FieldPulse, Workiz, QuickBooks — we pull your customers, equipment installed, service history, maintenance plans, and EPA logs into your new system in week one. Photos and historical job notes follow in week two. We do not rip out your old system on day one. Your current system runs side-by-side until you've signed off on every record.
Your data is encrypted both when moving and when stored. Privacy agreement signed before anything moves. Old exports deleted once you're live. Nothing imported automatically without you reviewing it first.
No per-tech fees.
Best fit: residential/service HVAC contractors with 2–8 trucks doing roughly $1.5M–$4M+ in annual revenue, with enough refrigerant work and service-plan volume to make EPA-grade logging and renewal automation pay off.
High call volume, complex permit/AHRI integrations, multi-location operations, custom accounting workflows, or unusually messy migrations are scoped separately.
Book the call →Most LA contractors are still on a generic Wix or GoDaddy template that doesn't reflect the business they actually run. While we're building your software, we'll build a modern custom website to go with it — your branding, your photography, plus your customer portal login, online booking, payments, and review links right on the homepage. A site like this is $7,500 on its own. Bundled with your build, it's $2,500 — because your brand and content work are already on the table, and we're already on the calendar. One launch day, one team, one bill.
