🌡️ HVAC
Time Clock Software for HVAC Companies
Techs are out on service calls all day, not sitting at a desk. CKZ confirms they're actually at the job site, ties every hour to the right client, and keeps overtime from surprising you at payroll.
Common HVAC Challenges
What service calls make complicated
No way to confirm a tech is on site
A tech says they arrived at 9, but did they? GPS geofencing checks location the moment they clock in — punches outside the customer's address can be flagged or blocked.
Hours not tied to the right client
One tech, five service calls, one day. Accounting codes let every punch get tagged to the job or client — hours by client is a report, not a guessing game at invoice time.
Techs are never at a desk
CKZ's mobile app clocks a tech in and out from wherever the van is parked — no browser, no office computer, works on iOS and Android.
Emergency calls push into overtime
An after-hours emergency call can tip a tech into OT without anyone noticing until payroll. Overtime threshold alerts warn supervisors in real time, not two weeks later.
How CKZ Fits HVAC
Feature by feature
Clock-ins verified at the customer's address.
Define a geofence around a job site — or use it ad hoc for one-off service calls. When a tech tries to clock in from outside the zone, the punch is blocked or flagged for review, and GPS coordinates are logged with every punch either way.

Every punch tagged to a client. Know your real labor cost per call.
Each clock-in prompts the tech to select a job code — client name, service ticket, or job type. Pull an "hours by client" report to see exactly how much labor went into each account, without reconstructing it from memory at invoice time.

See overtime coming before payroll does.
Emergency calls and long install days push hours up fast. The supervisor dashboard flags anyone approaching overtime in real time, so you can make a staffing call before the week ends instead of getting surprised by the payroll total.
