Solving challenging HVAC/R problems is your job. Helping you get the right parts, supplies, and equipment—and manage sites in the field—is ours. The Carrier Service Technician app brings residential and commercial technician tools together in one Carrier experience. Whether you’re standing in front of a residential unit or covering commercial sites and equipment, the app is built for how technicians actually work on the job. Use the same Carrier sign-in you already have. Your role and permissions carry over, so you see the sites, equipment, and content you’re authorized to access—no new account, no new password. RESIDENTIAL TECHNICIAN EXPERIENCE Whether it’s warranty repairs for Carrier equipment or non-warranty repairs on any make or brand, the app helps you identify the right part at the job site. On-board GPS helps you find the closest location for parts when you need them. COMMERCIAL TECHNICIAN EXPERIENCE Field-ready tools for commercial sites and equipment—without opening a laptop. Get a quick read on the sites you cover, check equipment status on the spot, and dig into site and equipment details when you need specs and history. Work offline in basement mechanical rooms or on rooftops with no signal; your data caches and syncs when you’re back online. Meet Willis—ask about an alarm code for troubleshooting steps, or search official commercial OEM manuals and pull the section you need so you spend less time in PDFs and more time fixing the unit.
