Mechanical / HVAC Design Services
Code-aware HVAC and hydronic design with coordinated Revit models, from load calcs to construction-ready sheets.
MEP Design
Mechanical design: built for constructability
Heaven Designs delivers mechanical and HVAC design packages for residential, commercial, healthcare, industrial, and special facilities. We size systems correctly, route ducts and pipes for coordination, and produce models your construction team can build from.
Whether you need greenfield plant rooms or brownfield retrofits, our team works in Autodesk Revit MEP and AutoCAD to align with your architect and structural models, reducing clashes before they hit the site.
Typical engagements start with your architectural backgrounds and design criteria. We develop heating and cooling strategy, equipment selections, and coordinated layouts for ceilings, shafts, and plant rooms. The result is a mechanical package that supports pricing, coordination meetings, and installation.
Firms use us as an extended mechanical design desk. Owners and developers use us when they need a clear HVAC plan without building a full in-house engineering team.

A transparent workflow so you always know what happens next.
Inputs & criteria
Architecture, loads notes, climate assumptions, and preferred equipment brands.
Concept systems
System type selection and major equipment strategy for your building type.
Detailed modeling
Duct, pipe, and equipment modeled in Revit with progressive reviews.
Coordination pass
Align with structure, architecture, and other MEP trades.
Sheets & handoff

QUALITY
QA before every delivery
Packages leave only after internal review. The goal is fewer RFIs, cleaner coordination, and models that do not surprise the site team.
- Model naming, levels, and view discipline checked against project standards
- Critical dimensions validated against source drawings where conversion applies
- System connectivity and connector logic reviewed on MEP families
- Clash priorities reviewed for plant rooms, corridors, and ceiling zones
- Sheet sets checked for missing tags, schedules, and callouts
- Revision cloud / change log maintained through client feedback cycles
