Can I count outlets and diffusers across mechanical sheets?

Yes. The Count tool lets you tally diffusers, grilles, and head units across the mechanical plans, keeping a running total for the quote.

Can I measure duct and pipe runs?

Measure supply and return duct runs and refrigerant pipe lengths directly on the plan once the scale is set, so material lengths are based on the drawing.

Can I size systems from room areas?

Measure room and zone areas on the plan to help size systems and quote, keeping each zone in its own layer for larger jobs.

How do I estimate refrigerant pipe runs for a split or VRF system?

Measure the run from each indoor head back to the outdoor unit on the plan with the Measure tool, and MetreMate totals the lineal metres. Add your allowance for rises and bends and you have the pipe length for the quote.

How accurate is a duct takeoff off a mechanical plan?

As accurate as the drawing. Once the scale is set and snapping locks onto the duct lines, your supply and return run lengths match the plan, so your sheet metal or flexible duct order is reliable.

Can I keep supply, return, and refrigerant runs on separate layers?

Yes. Put each system on its own layer as you measure, so supply air, return air, and refrigerant runs total separately. That keeps a larger mechanical takeoff organised and easy to price by element.

MetreMate for Heating & Cooling Technicians

Measure HVAC layouts and duct runs from plans

Measure duct runs, count outlets, and size zones from mechanical plans to quote heating and cooling installs.

No credit card needed. Free plan to start, works on Windows and Mac.

Under 90s to your first measurement

Why heating & cooling technicians choose MetreMate

Heating and cooling technicians use MetreMate to measure ducts, count outlets and units, and size rooms from mechanical plans. Measure supply and return ducts and refrigerant runs, count every outlet and unit with the Count tool, and use room areas as the starting point for the kW each room needs. It runs in your browser, so you can quote an HVAC install from the plan without marking up a printout.
