What we do

About us

We are a testing, adjusting and balancing contractor working across the Greater Toronto Area. Despite the name, our trade is HVAC — we measure airflow and water flow on commercial systems and tune them to the engineer’s design intent.

Mechanical contractors and building owners bring us in at fit-out, commissioning and retrofit. We turn up with the instruments, do the traverse and the balance, and leave you with a signed-off report your consultant can file.

  3. Report for close-outYou get a signed, documented TAB report formatted for consultants and close-out binders.
