Custom HVAC software, built to fit your shop.
For shops with maintenance agreements, membership plans, multiple locations, or billing rules the off-the-shelf version can't express. We build your logic on a service-business foundation that's already proven in the field.
Start a discovery callThe proven core, plus what makes your shop different.
A custom HVAC build starts from Cardo CRM's service foundation — scheduling, dispatch, on-site invoicing, Stripe payments, two-way SMS and a technician app that already run a real service business — and then adds the parts unique to your shop. Maintenance agreements with their own renewal and billing logic, membership tiers, equipment and warranty history, multi-location dispatch: the things generic software bolts on awkwardly, we build to fit. You're not paying a developer to relearn how a service call works; you're paying for the layer that's actually yours.

What a custom HVAC build usually adds.
The off-the-shelf Cardo CRM already handles the daily core of an HVAC shop — service-call dispatch, technician scheduling, reminders and pay-on-the-spot invoicing. A custom build is for the logic that sits outside that and that no settings screen can express. The classic examples are maintenance agreements and membership plans with your exact terms, billed on your exact cadence; multi-location or franchise reporting that rolls branch performance up into one view; equipment and warranty history tracked per system across years of visits; and integrations with the distributor, accounting or proposal tools your shop already runs on. These are the places generic field-service software makes you keep a spreadsheet — and that spreadsheet is the business case for building.
Crucially, none of it starts from a blank page. We build your custom logic on top of the same proven foundation that runs a real service company every day, so the scheduling, dispatch, payments and messaging already work on day one and we're only adding the parts that make your shop different. That's why a custom HVAC build costs a fraction of a from-scratch project and ships in weeks: you're extending working software, not reinventing it, and you own the result.
You own it, and it grows with your shop.
A custom HVAC build is deployed on your own instance and the code is yours — you're never locked out of the system your shop runs on, and you're not waiting on someone else's roadmap for the capability you need next. As your business changes — a new membership program, another location, a different way of handling warranty work — the software bends with it, because it was built around your process in the first place rather than rented as-is. That ownership is a fundamentally different relationship with your tools than paying monthly for software you can only use the way it was designed.
It's also why established shops make the jump. The off-the-shelf product is the right, fast, affordable starting point for most HVAC companies, and we'll say so on the discovery call. But once maintenance agreements, multi-location reporting or distributor integrations become central to how you operate, owning a system shaped exactly to that stops being a luxury and starts paying for itself in the daily workarounds it eliminates — and in the fact that the software can finally keep up with how your shop actually runs.
Custom HVAC software FAQs
What do HVAC shops usually need custom?
+
Most often: maintenance-agreement billing and renewals, membership/club plans, multi-location or multi-brand dispatch, equipment and warranty tracking, or integrations with a specific accounting or supplier system. If your needs are simpler, the standard Cardo CRM likely covers them.
Can you build recurring maintenance-agreement billing?
+
Yes — that’s a common custom build. We model your plan tiers, visit cadence, renewals and billing the way your shop sells them, rather than forcing them into a generic recurring invoice.
Do we own and control the system?
+
Yes. Your build runs on your own deployment, you own the code, and we host and maintain it on a monthly plan. Your data is always yours.
How is it priced?
+
Custom HVAC builds are quoted per project. After a discovery interview we scope exactly what needs building and agree one fixed price up front — no hourly surprises.
