Why HVAC on EveryEng
The complete free HVAC design curriculum
HVAC design sits at the intersection of thermodynamics, fluid mechanics, psychrometrics, and controls — and it is one of the fastest-growing engineering specialisations in the world. The data-centre build-out for AI workloads, net-zero building mandates, district cooling, and heat-pump retrofits are all driving record HVAC hiring across the UK, Gulf, Singapore, and US East Coast.
EveryEng's 120+ HVAC courses cover everything a building services or industrial HVAC engineer needs: cooling and heating load calculations per ASHRAE methods, duct design and sizing, chiller plant configuration and optimisation, psychrometric process analysis, and fire- and smoke-control ventilation strategies. Software coverage includes Carrier HAP, Trane TRACE 700, IES VE, and Revit MEP.
Every course is free, CPD-accredited, and aligned with ASHRAE 90.1, ASHRAE 62.1, CIBSE, and SMACNA standards — the same references your design lead will expect you to cite in a project review.
What You Will Learn
Six pillars of HVAC design competence
From cooling-load fundamentals to advanced fire-and-smoke strategies — every skill a building services engineer needs.
Duct Design & Sizing
Equal-friction, static-regain, and velocity reduction methods; SMACNA standards; low-leakage construction; acoustic treatment.
Chiller Plant Design
Central chiller plants, primary-secondary vs. variable-primary, cooling towers, condenser water optimisation, and thermal storage.
Psychrometrics
Psychrometric chart mastery, mixing calculations, cooling-coil process lines, dehumidification, and wet-bulb economizers.
Heating Systems
Hot-water boilers, heat pumps, radiant panel systems, district heating, and emerging decarbonised heating strategies.
Codes & Standards
ASHRAE 90.1 (energy), ASHRAE 62.1 (ventilation), CIBSE guides, SMACNA, and NFPA 90A/B fire-safety integration.
Curriculum
11 modules — foundations to advanced
Start anywhere in the track. Every module awards its own CPD-accredited certificate.
HVAC Fundamentals
Thermodynamics refresher, heat-transfer modes, psychrometric basics, and the building energy balance.
Cooling Load Calculations
ASHRAE CLTD/CLF method, RTS method, solar gain, and room-by-room tabulation.
Heating Load Calculations
Winter design conditions, transmission losses, infiltration, and ventilation heating.
Psychrometrics & Process Lines
Mixing, cooling, heating, humidification/dehumidification, and supply-air design conditions.
Duct Design & Sizing
Three sizing methods, ductwork layout, fittings losses, and low-leakage SMACNA construction.
Air Distribution & Diffusers
Throw, drop, ADPI, and diffuser selection for offices, hospitals, and cleanrooms.
AHU, FCU & VAV Selection
Equipment selection logic, coil sizing, fan curves, and controls integration.
Chiller Plants & Hydronics
Primary/secondary pumping, chilled-water distribution, condenser loops, and tower selection.
Heating Plants & Heat Pumps
Boiler sizing, heat-pump selection, VRF systems, and decarbonised heating strategies.
Energy Codes & Green Buildings
ASHRAE 90.1, IECC, LEED, WELL, and Passivhaus mechanical criteria.
Fire & Smoke Control Ventilation
NFPA 92, stair pressurisation, smoke extract, and control-matrix coordination with fire alarm.
Accreditation
Recognized by leading building services bodies
EveryEng HVAC certificates count toward CPD with these institutions.

FAQ
Frequently Asked Questions
Yes. The catalog starts from first principles — thermodynamics refreshers, psychrometrics basics, and what a cooling load actually represents — before moving into detailed design. Beginners and engineering students can start from module 1 with no HVAC background.
