One firm. Three focused services.
Avidan Design is an Orlando engineering firm focused on HVAC load and energy calculations, electrical load and panel schedules, and structural layout engineering — clean, complete work prepared for permit review.
Right-sized systems and buildable layouts.
Oversized HVAC equipment wastes money. An incomplete panel schedule stalls a permit. A structural layout that is not drawn to be built causes field questions.
Avidan exists to get these three things right the first time — with the correct calculation method and code, no shortcuts and no invented numbers.
A focused, disciplined practice.
- Central Florida focus — Orlando, Orange, Seminole, Osceola, Volusia
- Verified calculation methods — Manual J/N/S, EnergyGauge, NEC 2020
- Residential and light commercial work
- Clear scope before we start — no fixed-scope surprises
- Deliverables prepared for permit review
- Honest routing — if it's outside our three services, we say so
Three steps that shape every engagement.
The process is the same whether it's a single load calculation or a full structural layout package.
