Field service app for HVAC company
During this project, the ElifTech team developed and released a custom solution for a well-known HVAC service provider. We took their old work order system that relied largely on manual processes, gave it a complete makeover, and linked it with a better system with extended billing capacities. The platform streamlined their operations, minimized scheduling conflicts, and enhanced billing accuracy – critical factors in delivering superior customer service in the HVAC industry. At the same time, a mobile application was developed for field service employees’ convenience.
The project's highlights included a real-time scheduling system, work order system, and a comprehensive billing module, simplifying the previously complex and manual process. These advancements not only improved backend efficiency but also contributed significantly to their financial performance, creating a more cohesive and efficient service delivery system.

About the client
Our client is a HVAC service provider with a broad footprint across the United States, offering comprehensive services for residential and commercial systems. With over 15 years in the industry, they specialize in installation, maintenance, and emergency repairs, including but not limited to central air systems, ductless mini-split systems, furnaces, heat pumps, and indoor air quality improvements. The company's vast network and operational needs – including precise scheduling, emergency responses, and inventory management – posed unique challenges.
Challenge
The client relied on an outdated, manual-driven system for scheduling and dispatching, which led to frequent scheduling conflicts, including double-bookings and technician misallocations. This inefficiency in a demanding HVAC market caused customer dissatisfaction and service delays. Additionally, an outdated digital billing system operated in isolation, disconnected from the scheduling operations. This required employees to manually input service details into the billing system – an inefficient and error-prone process that resulted in billing inaccuracies and invoicing delays, negatively impacting the company's financial performance The lack of integration meant that services were not always invoiced correctly or promptly, with manual errors exacerbating the problem.

Solution
-
System Solution
Our team integrated APIs for seamless data exchange between scheduling, dispatching, and billing components, automating the entire flow to cut down on manual data entry errors. For this, we used Node.js because it's great for managing lots of requests without slowing down.
-
Custom Workflow and Algorithm Optimization
We designed custom algorithms to automatically assign tasks based on technician skills, availability, and location, thereby optimizing the dispatch process and maximizing efficiency.
-
Work Order and Scheduling Dashboard
Creating an interactive dashboard would offer schedulers and dispatchers a bird’s eye view of all the tasks. It would feature information like task status, technician assignments, and any scheduling conflicts all on one screen.
-
User-Friendly Interface
While developing the new software, the priority was to make it user-friendly, ensuring it could be easily adopted by the client's staff. The interface was designed to be intuitive, aiming to reduce the learning curve and increase productivity.
