Custom software for HVAC, plumbing & electrical contractors
ServiceTitan, Jobber, and Housecall Pro run your dispatch — but MEP work needs more. LyonHawk Digital builds the equipment portals, estimating calculators, and subcontractor dispatch tools that plug into your stack via API. You own what we build; your core platform stays put.
The gap
Commercial clients want maintenance histories, refrigerant logs, and photo reports for every chiller on the roof. Your CRM stores the job — not the asset. So coordinators rebuild the story in email every time the client asks.
Estimating a $75k ductwork replacement or a commercial electrical rewire in ServiceTitan or Jobber means spreadsheets, guesswork, and re-keying the finished number back into the CRM. Multi-variable job costing wasn't built for this.
Crane operators, backflow inspectors, and third-party specialists get one job, not a login. Buying another SaaS license — or running them through email — slows dispatch and loses the audit trail.
LyonHawk Digital builds lightweight, owned modules that handle the MEP-specific workflows your field-service tool wasn't designed for — then pushes data back through the API so your team stays in one system of record.
What we build
We don't rip out your stack. We build the modules your platform's roadmap won't — and wire them in so your office never re-keys the same data twice.
A lightweight portal where commercial clients see every unit on their property — maintenance history, refrigerant logs, filter changes, and photo reports — without an expensive login buried in your main SaaS.
e.g. Commercial HVAC client pulls chiller history before a board meeting, without calling your office.
Custom estimating engines for jobs too complex for a flat-rate book — ductwork replacements, commercial rewires, multi-phase mechanical installs. Finished quotes push straight into ServiceTitan, Jobber, or Housecall Pro via API.
e.g. Estimator prices a $75k rewire in 60 seconds; the job appears in your CRM ready to send.
Assign crane operators, backflow inspectors, and third-party specialists from a dedicated portal — confirm availability, share site details, and capture sign-off — without buying another $300/month seat license.
e.g. Rooftop unit swap: crane op gets the dispatch, confirms, and closes out — no email thread.
The ownership pledge
The modules we build live in your cloud account and integrate with tools you already pay for. No vendor lock-in on top of vendor lock-in — if we part ways, the extension keeps running.
The repository is transferred to an account in your name. Full commit history, API integration docs included.
Hosting and database live in accounts you control. We're operators on your account, not the owner of it.
Equipment records, bid history, and subcontractor logs in standard Postgres. Export everything, anytime — and sync what matters back to your CRM.
Cancel your care plan whenever you like. The extension keeps running alongside your field-service platform.
How it works
A free 30-minute call. You show us the workflow your platform can't handle — equipment reporting, complex bids, subcontractor handoffs — and we map where an extension fits without disrupting what already works.
You get a written proposal with a fixed price, delivery date, and exactly which API integrations version one includes. No hourly meters, no surprise invoices.
We ship something your team can click every week, starting with the thinnest slice that proves the integration. You steer while we build, not after.
We deploy to your cloud account, connect the APIs, train your team, and hand over the keys. A monthly care plan keeps the extension fast, secure, and evolving.
Case studies
These aren't rip-and-replace stories. Each shop kept their field-service platform and added a module that closed a gap nothing off-the-shelf handled.

What clients say
“We didn't leave ServiceTitan — we added the equipment portal our commercial clients had been asking for for two years. They stopped calling for logs; they just log in.”
Dana Whitfield
Operations Manager, commercial HVAC contractor
“Our commercial bids used to live in Excel and die in Excel. Now the calculator pushes straight into Jobber and my estimator actually enjoys the process.”
Marcus Bell
Owner, electrical contracting company
“Crane ops and backflow inspectors don't need a Housecall Pro seat. The dispatch portal cost less than two months of licenses and we own it.”
Priya Raman
Owner, commercial plumbing company
FAQ
No — that's the point. We build extensions for shops already on ServiceTitan, Jobber, Housecall Pro, BuildOps, or Service Fusion. Your platform stays your system of record; we fill the MEP-specific gaps it wasn't designed for and sync data back via API.
We've built against ServiceTitan, Jobber, and Housecall Pro APIs most often. BuildOps and Service Fusion are on the list too. Discovery calls start with a quick API audit — we'll tell you honestly if the integration you need is feasible before quoting.
Yes — contractually. The code lives in a repository under your account, the app runs in a cloud account in your name, and the database is standard Postgres you can export anytime. Your field-service platform subscription is separate and unchanged.
Most first releases ship in 4–8 weeks. We work in weekly slices, so your team will be clicking through a working integration by week two — not waiting for a big reveal at the end.
Every build is custom-quoted with a fixed price before we start. Most first releases land between $2,500 and $15,000 depending on scope and API complexity. There's no hourly meter — if we misjudge the effort, that's on us.
The extension keeps running — it's in your cloud account. You'd take over hosting bills (typically $20–50/month) and lose our monitoring, backups, and included hours. Your field-service platform is unaffected.

Book a free 30-minute discovery call. Bring your field-service tool, the workflow that's stuck in spreadsheets, and we'll tell you honestly whether a custom extension is the right fix.
Best fit: MEP contractors (HVAC, plumbing, electrical) already on ServiceTitan, Jobber, Housecall Pro, BuildOps, or Service Fusion — with a workflow gap that spreadsheets or extra seat licenses are papering over. Not a fit: shops with no platform yet, or venture-scale app ideas.
