Dallas HVAC engineering — what we do here
Cinch MEP is a TACLA-licensed Texas HVAC engineering firm. We submit stamped Manual J calculations to Dallas's building department regularly and know what their reviewers want to see on the first submission.
Contractors, builders, and homeowners in Dallas can typically get stamped, AHJ-ready PDFs within 24-48 hours. Same-day available if ordered before 10 AM CT.
Dallas Building Inspections
City of Dallas — Building Inspection (Development Services)
- Submission portal:
- Dallas ProjectDox portal at dallascityhall.com/permits
- What they ask for:
- Manual J for residential mechanical permits; commercial loads per IECC; Dallas reviewers can be backlogged so clean first-submit matters more here than other DFW cities
- Common AHJ asks:
- Window/door specs sometimes requested separately; older Dallas housing stock often has unknown envelope details that we estimate conservatively; design temperatures (98° summer / 22° winter — slightly warmer design temp than the suburbs)
What we deliver for Dallas projects

Dallas areas we work
Lake Highlands, Lakewood, Preston Hollow, M Streets, Bishop Arts, Greenway Parks, East Dallas, Oak Cliff, Bluffview, Devonshire, Forest Hills, and downtown Dallas conversions.
Common Dallas scenarios we solve
Lakewood or M Streets historic remodel: Older homes with retrofitted HVAC need stamped Manual J for the renovation permit. We work with what's known and estimate conservatively where envelope details are unclear.
Lake Highlands HVAC replacement permit: Common kickback scenario when a homeowner replaces an older system. Same-day catch-up calc available.
Downtown Dallas loft conversion or commercial TI: Manual N + Q for tenant finish-out in older commercial buildings. We've sized for converted lofts, retail, and small office.
Bishop Arts restaurant finish-out: Manual N + Q plus refrigeration design for restaurant TI. The TACLA Combo license covers all of it under one stamp.
