As HVACR professionals, we are in the business of heat. We install systems in buildings and homes that either add heat or remove it. We maintain, tune, and repair these systems for our customers. We use our knowledge of how heat travels from one substance to another to enhance our customers' comfort and to help keep their utility expenditure to a minimum.
In this article, we will examine what heat is, the various types of heat, the dynamics involved in transferring heat from one substance to another, and the measurement of heat.
