Commercial HVAC and refrigeration lessons from the field, technical study, and the progression toward system design.
A homeowner thought his furnace exhaust pipe was leaking water, but the real problem pointed toward leaking ductwork, high humidity, and condensation. This field case shows how dew point, surface temperature, and airflow can help explain where the water was really coming from.

A homeowner thought his furnace exhaust pipe was leaking water, but the real problem pointed toward leaking ductwork, high humidity, and condensation. This field case shows how dew point, surface temperature, and airflow can help explain where the water was really coming from.
Airflow & Ventilation
Water around an AC vent does not always mean the system is leaking. Learn how humidity, dew point, duct insulation, air leakage, and surrounding attic or crawlspace conditions can cause supply vents to sweat.
Airflow & Ventilation
Static pressure measures the resistance your HVAC blower works against. Learn how ducts, filters, coils, and fittings can affect airflow, comfort, noise, humidity, energy use, and equipment life.
HVAC Diagnostics
Explains why supply-air relative humidity can be higher even while the evaporator is removing moisture, and how duct leakage, damaged insulation, infiltration, airflow, and building pressure can contribute to indoor humidity problems.
General
Why studying beyond the repair is changing how I approach HVAC, troubleshooting, and the engineering behind complete systems.
HVAC Diagnostics
A real-world no-cool call that reinforced why fault codes are clues, thermostat history matters, and measurements still have to tell a complete story.
Engineering Study
An introduction to the purpose of The HVAC Engineer: connecting commercial HVAC field experience with deeper electrical and mechanical engineering study.
