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.

Not connecting from old control board to new control board
denis von
I spent 2 hours trying to replace a control board and trying to connect to the new board. Whenever I would “tap” to connect it would say an error has occurred. Then I manually put in whatever I needed and I would “tap” to connect to the new board and it would say an error has occurred. Why would you have to program a new board with an app when in the past companies would just use dip switches? I had to leave the customers house with no heat because this app would not connect to the old or new board.
Developer Response
Hi Denis, we're sorry you were left in that situation with no heat. Control board replacement workflows are a top priority for us right now. Please email us at digitalAppAdmin@carrier.com with your board model numbers so we can escalate this to our engineering team.
Terrible

Everytime I have to use this app even if it’s 4 times a week I have to update it and put my password back in. Yet nothing ever works better. The NFC tag can take 20 tries to work on a furnace. The barcode scanner on a furnace won’t bring anything up. Manually entering model numbers won’t do it. It’s just a constant fight, then after you get it to work it’ll just say they don’t have any parts data on that 5 year old carrier. Unacceptable.
Developer Response
Hi, these are real issues and we take them seriously. Please email us at digitalAppAdmin@carrier.com with your specific equipment details so we can investigate.
