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 makes this a non-question — every punch is geotagged and time-stamped at the moment of work.

Built for the way hvac contractors actually work.

Whether you do residential service, commercial installs, or both, Clox handles 3–30 techs without breaking a sweat.

Quick punches between calls

Techs tap in/out between calls without leaving the truck. Works offline; syncs when signal comes back.

Job-cost reports that match reality

Compare bid hours to actual hours per install. Catch the jobs that are bleeding before they bleed out.

On-call premiums, automated

Set on-call multipliers and weekend rates. Clox applies them automatically per the shift — no mental math.

Simple pricing

$5 per seat / month.

Every feature included. No usage caps. Pay only for hvac contractors on the team.
