dialed in.
Ventora is an AI HVAC assistant trained on IMC, ASHRAE, and ACCA manuals — grounded answers and six field calculators for techs on the roof.

HVAC, nothing else
Rooftops aren't reading rooms.
HVAC techs juggle manufacturer charging charts, ACCA manuals, a pressure-temperature card, and a calculator on every call. When you're on a rooftop unit trying to remember target subcooling for an R-410A TXV system, flipping through PDFs and charts isn't practical.
We built Ventora because the HVAC trade deserves better tools. Every question you'd ask a senior tech or look up in a manual — Ventora answers instantly, with the relevant IMC, ASHRAE, or manufacturer reference. Six professional calculators handle superheat, charge, airflow, and load. And unlike general AI, Ventora is trained specifically on HVAC systems and code.
Superheat & subcooling to the data plate
Target superheat and subcooling by refrigerant and metering device — confirm the system is charged to the data plate instead of guessing from memory.
- By refrigerant & metering device
- Data-plate verification
- P/T references built in
CFM from temp split in seconds
Get CFM from temperature split or duct velocity, checked against the 400 CFM-per-ton rule — airflow problems surface before they become callbacks.
- Temp split or velocity method
- Checked against 400 CFM/ton
- Duct sizing companion
Manual-J estimates, room by room
Room-by-room heating and cooling loads using ACCA Manual J methodology, sun exposure, and occupancy — sized right the first time.
- ACCA Manual J methodology
- Sun exposure & occupancy
- Heating & cooling
From question to charge target.
Ask anything HVAC
Type a question, describe a symptom, or snap a photo of a nameplate, control board, or error code.
Ventora references IMC & ASHRAE
AI trained on the mechanical code, ASHRAE standards, ACCA manuals, and refrigeration fundamentals.

- Cites IMC, ASHRAE & manufacturer specs
- Nameplate & error-code photo input
- Trained 100% on HVAC
Most R-410A TXV systems target:
- –8–12°F subcooling — always confirm against the charging chart on the unit's data plate
- –Verify the TXV is holding superheat in range (typically 8–14°F) before adjusting charge
- –Measure liquid line temp and pressure at the service valve, then find saturation temp on an R-410A P/T chart
Six field calculators.
Built on ACCA manuals, ASHRAE formulas, and standard refrigeration math.
BTU / Load
Room-by-room heating and cooling load estimates using ACCA Manual J methodology, sun exposure, and occupancy.
Superheat / Subcooling
Target superheat and subcooling by refrigerant and metering device. Confirms a system is charged to the data plate.
Refrigerant Charge
Adjusts factory charge for line-set length so you add or recover the right amount for the actual install.
Airflow / CFM
CFM from temperature split or duct velocity, checked against the 400 CFM-per-ton rule for proper airflow.
Duct Sizing
Size supply and return ducts by required CFM and velocity, or check whether an existing run is undersized.
Hydronic / Water-Side
BTU from flow, GPM from load, and pipe sizing for boilers and hydronic systems using ASHRAE fundamentals.
