Elite Software Rhvac
Windows desktop HVAC load-calculation suite covering Manual J residential and light-commercial loads, Manual S equipment selection, and Manual D duct sizing -- with optional cloud access via Rhvac Online.
3.6 /5 composite score
Best perpetual-license HVAC load-calc tool for a solo engineer -- $599 one-time for Rhvac buys ACCA-certified Manual J/S/D on Windows with no annual renewal, and Rhvac Online adds browser access; the desktop-only default and absent Capterra presence are the only friction points.
Rubric Scorecard
| Criterion | Score | Rationale |
|---|---|---|
| Maturity | 4/5 | Long-established suite with 30+ programs spanning HVAC, electrical, plumbing, and fire protection; Rhvac Online cloud portal available alongside the installed desktop version; regular maintenance releases. |
| AEC Specificity | 5/5 | Purpose-built ACCA Manual J, S, and D workflow in one tool: room-by-room load inputs, equipment selection from embedded catalogs, and duct system design -- the narrowest and most complete residential HVAC calc path available. |
| Integration | 2/5 | Windows desktop install with separate cloud access via elitesoftapps.com; no BIM or CAD integration; lowest portability of any tool in this category. |
| Value / Pricing | 4/5 | $599 one-time for Rhvac; a bundle with Drawing Board and Ductsize runs $999 -- the perpetual license with no annual fee is the best long-run value for a solo engineer doing high-volume residential load calcs. |
| Evidence | 3/5 | Independently confirmed by HVACR Comfort Pro reseller listing at $599; getconduit.com comparison blog cites Rhvac's Manual J depth; no Capterra or G2 reviews found. |
