About Plenum
Software built in a Denver HVAC shop, for the next one.
Plenum comes from the team behind UniColorado Heating & Cooling and was built to run their own day. It is still built on their jobs.
Denver roots
UniColorado has installed heating and cooling across Denver and the Front Range since 2014. Cold winters, hot summers and a lot of heat pumps. The office books, dispatches, quotes, bills and files rebates every day, and the tools for that never fit together.

Built on real jobs
So the team built Plenum around their own day. New screens go to work on UniColorado's jobs first. When something is slow, unclear or wrong, someone in the office or the field says so that day. Then it gets fixed.
Part of the .blue family
The same team builds a few smaller tools for the work around the job. calc.blue does load calculations. rebate.blue and spec.blue look up equipment. heatpump.blue helps homeowners, and prop.blue holds property data.

About Plenum
What is Plenum?
Field service software for residential HVAC contractors. Booking, dispatch, the field app, estimates, invoicing, the portal and rebate paperwork share one customer record.
Is Plenum only for HVAC?
It is built on an HVAC shop's day, with equipment and rebate work built in. Plumbing and electrical shops can use it, but HVAC comes first.
Can I migrate my existing data?
Yes. We review your current system and import supported customer, job history and pricebook data. You check the records before you switch.
Do I need to train my team?
We run guided onboarding for the office and the field, with documentation and ongoing support.
Want to build it with us?
We keep the team small and read every thoughtful note.
