01 Diagnosis

Problems we solve for HVAC businesses

  1. 01
    Problem

    Missed service calls turning confirmed revenue into complaints and lost contracts

    Solution

    According to AgentZap's 2024 HVAC industry benchmarking, the typical HVAC contractor misses nearly 25% of all incoming calls, rising to 35% or more during peak seasons, with each missed call representing at least $350 in lost revenue. Most of those calls are maintenance renewals, seasonal tune-up requests, and emergency dispatch that the customer will book with a competitor the same day.When call handling, dispatch, and maintenance renewal workflows are disconnected, missed calls don't surface as a problem until a contract lapses or a customer stops renewing. A connected scheduling and service management platform closes that gap, automating renewal outreach, routing inbound requests to the right dispatcher, and capturing jobs that paper and spreadsheet processes quietly lose.

  2. 02
    Problem

    Preventive maintenance schedules managed in spreadsheets, causing missed visits and lost contract revenue

    Solution

    Commercial maintenance contracts are worth more per year than dozens of one-off repair calls. When schedules live in a spreadsheet, visits slip through. Customers notice. Contracts get cancelled.There's no automated trigger to generate and dispatch the visit before the due date passes. A missed PM visit is revenue you've already been paid for, but failed to deliver.

  3. 03
    Problem

    Technicians arriving on site without equipment service history, duplicating diagnostic work already done

    Solution

    Every HVAC unit has a fault pattern. When the previous technician's notes stay in a paper job card filed back at the office, the next technician starts blind. Diagnosis takes longer. Customers ask why you don't know what was done last time.That question damages trust. And it's entirely avoidable.

  4. 04
    Problem

    Parts and van stock managed by memory, so jobs stall waiting for a part the technician doesn't have

    Solution

    When van inventory isn't tracked, technicians guess what to carry. They arrive at a job, identify the fault, and find they don't have the part. The job gets rescheduled, the customer waits, and the technician drives back to the depot. That's a wasted half-day and a frustrated customer.Visible van stock means jobs are completed in one visit. Low-stock alerts mean replenishment happens before the shelf is empty.

  5. 05
    Problem

    Warranty claim submissions delayed because job records don't capture the right data at the point of service

    Solution

    Warranty claims require specific information: installation date, fault code, parts replaced, technician sign-off. When job records are captured on paper, that data is often incomplete. Claims get rejected or queried. The admin team chases the technician for details weeks after the job closed.Capturing structured data at the point of service means warranty submissions go out complete the first time.

03 How we work

How we build HVAC software

  1. 01

    Discovery

    We spend the first two weeks mapping your current dispatch workflow, maintenance contract structure, equipment records, and technician mobile experience. We interview the operations manager, a dispatcher, and at least one field technician. The output is a documented requirements list and a gap analysis against any platforms you already use. That way we're building what you need, not a generic field service template.

  2. 02

    Architecture

    We design the data model around your equipment registry and service interval logic before writing any application code. This step defines how maintenance schedules are generated, how technician assignment works, what the mobile app stores locally for offline use, and which external systems (Xero, QuickBooks, GPS providers, parts suppliers) connect and how. You review and sign off on the architecture document before development begins.

  3. 03

    Build

    Development runs in two-week sprints with a working demo at the end of every sprint. We start with the scheduling engine and job dispatch layer, then build the technician mobile app, then the quoting and customer portal layers. You test with real data as each module completes, not at the end of the project when changes are expensive.

  4. 04

    Launch and Support

    Go-live is phased: one or two technicians run on the new system alongside the old process for the first week. When data integrity is confirmed, the rest of the team cuts over. We monitor the first month actively, fix any production issues at no additional cost, and hand over documentation and training materials. Post-launch changes are quoted and agreed as discrete pieces of work.

08 Questions

Frequently asked questions

Established HVAC field service platforms handle core scheduling, dispatch, and invoicing well for most contractors. Custom software is the right choice when your maintenance plan structure, commercial proposal process, or equipment tracking requirements are specific enough that platform configuration takes more effort than the tool saves. It's also the right choice when you want to own the customer experience through a branded portal rather than a white-label module, when you're managing a large commercial maintenance book across hundreds of equipment units with complex service schedules, or when you're building a field service software product to sell to other HVAC contractors. The wrong choice is building custom when a well-configured platform solves the same problem at lower cost. We'll tell you directly which situation you're in.

Yes. This is one of the core problems we design HVAC software around. The data model needs to handle equipment-level service intervals, not just customer-level schedules. A commercial account with a 10-unit building may have different filter replacement intervals, warranty terms, and inspection schedules per unit. The scheduling engine generates the forward calendar of required visits from those equipment records, dispatches the technician, logs the completion, and resets the next visit date. At hundreds of accounts, this has to be automatic. It can't be a dispatcher manually checking a spreadsheet every morning.

Yes. Accounting integration with Xero and QuickBooks is standard: invoices, payments, and purchase orders sync without double entry. Parts supplier integration depends on the supplier. We build price catalogue integrations where suppliers provide an API or a structured feed, so your technicians and office staff always quote with current pricing. GPS and mapping integration for real-time technician location and route optimisation is included. Integration with smart thermostat and building management systems for commercial customers who want equipment status visibility connected to your service platform is a separate and more complex project that we scope individually.

A focused scheduling and dispatch platform with a technician mobile app typically runs $35,000 to $70,000. A full platform covering scheduling, preventive maintenance management, a technician mobile app, quoting and proposals, equipment service history, parts inventory, a customer portal, and invoicing typically runs $90,000 to $160,000. Multi-location HVAC businesses with large commercial maintenance books and complex dispatch requirements are scoped individually. Cost depends on the number of technicians, service area complexity, commercial account volume, and integration requirements. Every project is priced at fixed cost, agreed before development starts.

HVAC software by product

HVAC software built for preventive maintenance contracts and seasonal complexity

HVAC is a field service business with a subscription model hiding inside it. Preventive maintenance contracts are the most valuable part of your revenue: they're predictable, they drive technician utilisation in the off-peak season, and they keep commercial customers in your account rather than calling a competitor when the system breaks down in August.

The software problem is managing hundreds of maintenance schedules, equipment records, and service histories without a dedicated team doing it manually. We build the tools that automate the scheduling, track the equipment, and give technicians the information they need on site.
