TM Heating and Cooling Unifies Construction and Service Operations with Acumatica and Aktion
April 16, 2026 Aktion’s customer success and insights team
The Story
TM Heating and Cooling, an HVAC contractor based in Narvon, Pennsylvania, operates a multifaceted business that spans commercial construction, residential work, and ongoing service operations. As the company grew more complex, leadership recognized that their legacy system could no longer support all aspects of the business under one roof.
To create a more connected, scalable operation, TM Heating and Cooling partnered with Aktion to implement the Acumatica Construction Edition. The result is a unified ERP platform that connects inventory, payroll, construction projects, and service work, providing the team with real-time visibility and the flexibility to grow without constantly changing systems.
We needed something that could handle all sides of our business—construction, service, payroll, and inventory—in one system. Acumatica gave us that.

Key Results
Unified construction and service operations in a single ERP platform
Improved inventory visibility across warehouse, job sites, and service calls
Connected service callbacks directly to construction projects for accurate job costing
Streamlined payroll for both installation crews and service technicians
Accelerated customer payments using Acumatica Payments and QR-code invoicing
Reduced reliance on heavy customizations, simplifying upgrades and long-term maintenance
Built a scalable ERP foundation to support future growth
The Challenges
Before Acumatica, TM Heating and Cooling relied on a locally developed accounting system that worked well for smaller, simpler operations, but struggled as the business evolved. Managing construction projects, service work, inventory, and payroll across one platform became increasingly difficult. The system lacked the flexibility needed to support multiple operational workflows, particularly as the company balanced both long-term construction projects and high[1]volume service work. Leadership needed a solution that could bring everything together without forcing the business into separate systems or disconnected processes.
It wasn’t just about growth in headcount—it was about being able to manage all the different parts of the company under one umbrella.

The Solution
TM Heating and Cooling selected Acumatica Construction Edition to provide a modern, cloud-based ERP that can handle both construction and service operations. Aktion partnered closely with the TM team throughout implementation, helping guide the organization through training, configuration, and go-live. One key aspect of the implementation strategy was keeping the system as close to standard as possible. Rather than relying on heavy customizations, the team focused on learning Acumatica’s core functionality, ensuring long-term stability and smoother upgrades. Aktion consultants played a critical role in enabling the team to understand the system deeply, empowering internal users to solve many challenges independently while still providing expert support when needed.
Standout Capabilities
Connected Construction and Service Operations: TM Heating and Cooling now manages both construction projects and service work within a single ERP environment. Inventory flows seamlessly from the warehouse to job sites and service technicians, while service callbacks can be linked directly back to original construction projects.
"We can tie service callbacks back to the original project and see the full picture of costs and profitability—even after the job is complete."
Improved Inventory and Job Cost Visibility: The inventory used for construction installs and service calls is tracked centrally, allowing the team to manage purchasing, usage, and availability with greater accuracy.
"Inventory links nicely across construction and service. That’s been a big benefit for us."
Payroll Across Teams: Payroll for installation crews and service technicians is handled within Acumatica, simplifying processes and ensuring consistency across the organization.
Faster Payments with Acumatica Payments: TM Heating and Cooling was an early adopter of Acumatica Payments, using QR codes and embedded payment links on invoices to make it easier for customers to pay.
"Customers can just scan the QR code or click the link and pay. It’s reduced the time it takes for us to receive payments significantly."
This innovation was even highlighted at Acumatica Summit 2023, showcasing TM Heating and Cooling as a forward-thinking customer.
The Aktion Partnership
A major factor in TM Heating and Cooling’s success has been the enablement-focused approach taken by Aktion. Rather than creating dependency, Aktion consultants helped train the team to confidently use Acumatica, leverage Acumatica University, and engage with the broader user community.
Aktion helped us learn the system so we could solve many issues ourselves. When something is above my head, that’s when I bring them in—and they’re always there to help.
Brian Zelinski | TM Heating & Cooling
General Manager
By keeping the system streamlined and empowering internal users, TM Heating and Cooling rarely experiences disruption during upgrades and avoids unnecessary complexity. “That early training made a huge difference. It set us up for long-term success.”
Ongoing Partnership
Today, TM Heating and Cooling continues to operate efficiently on Acumatica, with confidence that the platform can grow alongside the business. With a team of approximately 22 employees spanning a wide range of experience levels, Acumatica supports users across generations and roles. “It’s something any age group can learn if they’re willing to. Our team has adapted really well.” Looking ahead, the company sees opportunities to expand its use of Acumatica as new features and enhancements are released, especially on the service side. “The options for growth are there. That’s what excites me about Acumatica.”
The Bottom Line
By partnering with Aktion and implementing Acumatica Construction Edition, TM Heating and Cooling replaced a limiting legacy system with a unified, scalable ERP platform. The company now operates with greater visibility across construction, service, inventory, payroll, and payments, all supported by a partner that prioritizes long-term success.
For us, Acumatica just works. It fits the needs of our business today and gives us room to grow tomorrow.
