For hvac contractors
Time tracking built for HVAC contractors.
Service calls and installs run on different math: different rates, different overtime thresholds, different sites every day. Clox tracks them all from one phone, one tablet, one Friday export.

The Sunday-night problem
Three techs. Five service calls each. Twenty-two jobs.
By 5pm Friday, you have no idea who spent how long where. The customer is asking why Job 7 took 4.5 hours. Your tech says 3. The handwritten card says 4. Clox settles it. Every punch is geotagged and time-stamped at the moment of work.
What you get
Built for the way hvac contractors actually work.
Whether you do residential service, commercial installs, or both, Clox handles 3–30 techs.
Quick punches between calls
Techs tap in/out between calls without leaving the truck. Works offline and syncs when signal comes back.
Job-cost reports that match reality
Compare bid hours to actual hours per install. Catch the jobs that are losing money before they finish.
On-call premiums, automated
Set on-call multipliers and weekend rates. Clox applies them automatically per the shift. No mental math.
See it in action
Timesheets and job sites, in one place.
Your crew's punches become timesheets on their own. You see who is on each site and the hours behind every job. No spreadsheets.
Timesheets
Approve a week of hours in minutes
Every shift, break, and overtime hour is calculated and laid out by week. Review it, fix any outliers, and approve. Payroll is ready by Friday.
Worksites
Know who's actually on the job site
Set a GPS radius around each site. Clock-ins outside it get flagged. You see who's on the clock and where, so you bill the right job.
How it works
Up and running this week.
You run Clox from the web. Your crew clocks in from the Clox app on their phones. If some of the crew share one device, mount a tablet at the trailer and they punch in with a PIN.
Sign up and invite your crew
Create your account in under a minute, then text your hvac contractors a link. They sign up and start clocking in from their own phones.
They clock in, you see everything
One tap in, one tap out, on a phone or a shared tablet at the trailer. Geofencing, breaks, and overtime rules run on their own.
Export payroll, reclaim your weekend
Friday: one CSV export into QuickBooks or your payroll provider. The Sunday-night timecard math is gone.
Questions
Questions hvac contractors ask
Will my crew actually use it?
If they can use a phone, they can use Clox. Clocking in is a single tap. There's nothing to set up or remember. Crews on a shared tablet punch in with a short PIN.
Does it work without cell signal on a job site?
Yes. Punches are saved on the device and sync automatically the moment the phone is back in range.
How much does it cost?
A $29/month base that includes your first 3 users, then $6 per additional user. Every feature included, no usage caps. There's a 14-day free trial and no credit card required to start.
Does it handle overtime and breaks?
Yes. Daily and weekly overtime, lunch deductions, and state break rules are calculated automatically, including California's daily and double-time tiers.
Can I get the hours into QuickBooks?
Clox exports a clean CSV that imports directly into QuickBooks Online, or any payroll provider that takes a CSV.
