Can I keep separate assemblies for ducted, ductless, and VRF?

Yes. Each system type can be its own assembly with its own labor and material composition. Pick the right one for the job and the estimate fills out accordingly.

Does it handle equipment pricing with margin markups?

Yes. You can set equipment cost and markup separately from labor markup, so your residential change-out and your commercial install can use different pricing logic.

Can I quote service calls quickly?

Yes. Pre-built service assemblies let you send a quote in minutes instead of building one from scratch every time.

Will it work for both residential and commercial?

Yes. Many HVAC contractors run both. The Blocks doesn't force you into one mode — same cost catalog, different assemblies for different scopes.

HVAC estimating is more complicated than most software handles

Equipment selection drives 60% of the price

Picking the right unit, the right SEER, the right indoor unit configuration — the price swings thousands of dollars on a single line. A generic database can't keep up.

Ductwork linear feet vs equivalent length adds variance

Returns, supplies, plenums, and fittings each have their own takeoff math. Doing it on paper means slow, inconsistent bids.

Service tickets and big install jobs need different workflows

A change-out quote should take 10 minutes. A new commercial install should be priced in detail. One tool needs to handle both.
