Keeping your HVAC business running smoothly takes more than just skilled technicians. You need a system that keeps everything in sync — from your first customer call to the final invoice. Our HVAC software brings scheduling, dispatching, quoting, inventory, billing, and accounting together in one place, so nothing slips through the cracks.


Most HVAC software handles scheduling or invoicing. But commercial HVAC businesses need more than that.
Service Dynamics combines Microsoft Dynamics 365 Business Central with Dynamics 365 Field Service or ExpandIT to manage your entire operation (from service agreements and preventive maintenance to dispatch, inventory, and financials) in one connected system.
Track equipment history, manage recurring service contracts, automate maintenance schedules, and capture every labor hour and part used in real time. The result is a single source of truth across your business — so your office, dispatchers, and technicians are always working from the same data
HVAC software helps heating, ventilation, and air conditioning companies manage everyday operations. This includes technician dispatching, service contract management, inventory tracking, quoting, invoicing, job costing, and reporting.
At Service Dynamics, we offer a complete HVAC software solution by combining Microsoft Dynamics 365 Business Central with ExpandIT Field Service. This powerful combination gives you the tools to streamline both field and office operations using a single, cloud-based system.




No time & material surprises. You'll know exactly what you're paying before we start.
Coordinating technicians by hand or with outdated tools is a recipe for trouble. Missed appointments, overlapping jobs, and wasted time between calls all cost you money.
Some teams are still using paper for work orders, checklists, and signature sheets. It’s easy for paperwork to go missing, and it slows down invoicing and job tracking.
Without real-time updates, you’re guessing — where your techs are, whether a job is done, or if the right part is in stock for the next visit.
When job details trickle back to the office late, invoices go out late. And the later you bill, the longer you wait to get paid.
Your accounting, field service, inventory, and job costing all work together in a single system. No more bouncing between apps.
The Resource Planner makes it simple to assign jobs, reshuffle schedules, and see technician progress in real time.
Technicians can see their work orders, review job history, track time, log parts, capture signatures, and finish jobs right from any device — even without internet access.
Track your parts across trucks, warehouses, and job sites while building quotes and invoices in the same system. No double entry, no delays.
Easily track recurring jobs and agreements to keep work steady year-round.
See job progress, profitability, and technician performance while work is still underway.
Our HVAC software is a great fit for:


Many HVAC companies start with QuickBooks and a separate scheduling tool. It works early on, but as service agreements, maintenance schedules, and technician teams grow, those systems become disconnected.
You end up with double entry, missed information between dispatch and accounting, and little visibility into which service calls or contracts are actually profitable.
Service Dynamics replaces that patchwork with one connected system. Your dispatching, service agreements, inventory, job costing, and financials all work together so nothing falls through the cracks.
It’s software that helps HVAC companies handle scheduling, dispatching, quoting, invoicing, inventory, and reporting in one place. Ours combines Business Central for the office side and ExpandIT for field service management.
Any company that installs, repairs, or maintains HVAC systems — residential, commercial, or industrial — can benefit. That includes contractors with service agreements, emergency repair teams, and mechanical contractors.
