DRTX estimates mechanical scopes for commercial and residential projects — rooftop units, split systems, VRF, ductwork, piping, and controls. We size the equipment list from your mechanical schedules and take off the distribution down to the fitting.

Our HVAC estimates include equipment by tonnage and type, supply and return ductwork by gauge and linear footage, registers and diffusers, refrigerant and hydronic piping, controls and thermostats, and rigging and startup labor. We price to current equipment costs and your installation rate, with exclusions clearly noted (test-and-balance, commissioning, etc.) so the bid is defensible.

For mechanical subs juggling multiple bid invites, a retainer keeps the estimates flowing without the cost of an in-house estimator. You bid more, you win more.
