Does setting a thermostat too low directly cause an air conditioning system set in cool mode to freeze? The answer is, no, at least not directly. However, low evaporator load (low return temperature or low airflow) and low outdoor ambient temperature can both lead to evaporator coil freezing. Low indoor set-point can lead to low […]
I am in the midst of testing the accuracy and repeatability of different types of airflow measurements for techs in search of the most practical methods for different applications. One commonly taught method for measuring airflow is the temperature rise method where you use a heat source that produces a set # of btu/h such as […]
