  • 1. Introduction

    Temperature is critical for making a home livable. Jordan Smith, professional builder and owner of the design-build firm Smith House, in Austin, Texas, explains the importance of understanding modern HVAC systems so you can successfully manipulate temperature.

  • 2. Basic HVAC Design

    Jordan explains the science behind temperature, humidity, and infrared heat, and how these factors, together with a building’s layout and its orientation toward the sun, affect a building’s HVAC design.

  • 3. Latent Heat

    Learn the basics of how latent heat (hidden heat) works in relation to pressure and volume within an HVAC’s heat pump system.

  • 4. Ventilation

    Ventilation is a key function in an HVAC system that makes clean, safe air. Jordan shares strategies for improving ventilation in your home, like switching from natural gas ranges to induction.

  • 5. Ventilation Systems

    Learn how HVAC filters work and what Minimum Efficiency Reporting Value (MERV) filter ratings mean. Also: Jordan deconstructs a MERV-6 filter and a MERV-12 filter, compares their parts, and explains how often both filters should be replaced.

  • 6. Ductwork

    There are two main types of duct used in HVAC ductwork: flexible and rigid. Jordan explains their differences, when they work best, and their advantages and disadvantages.

  • 7. Heating Systems

    From fireplaces to furnaces to heat pumps, learn the various types of heating systems and how they work.

  • 8. Air Conditioners

    Jordan explains how various cooling systems work, from fans to evaporative coolers to air conditioners. He then takes you inside a window air conditioning unit, explaining how its different parts work to produce cold air.

  • 9. HVAC Systems

    Jordan shows where various HVAC parts are located in a residential home and explains how they cool, heat, ventilate, and filter air.

  • 10. Mini Split

    Jordan explains how VRFs (variable refrigerant flow) systems, or mini splits, are engineered.

  • 11. HVAC Design

    Jordan emphasizes why a building’s HVAC and structural design should be symbiotic and shares the HVAC motto he lives by: “Build it tight, then ventilate right.”

Who it's for: This course is designed for those entering the skilled trades, working technicians, project managers and general contractors looking to gain a strong foundation in the basic fundamentals of how HVAC systems keep spaces comfortable and healthy for new builds and renovations.
