With the variety of refrigerants a technician can encounter, remembering all the different acceptable system pressures can be difficult or even overwhelming. To make this task more manageable, think ...

In trade school, we were taught that the low-side pressure is consistent throughout the low side and that the high-side pressure is consistent throughout the high side. However, except for some small, ...

An HVAC pressure sensor is particularly important in the cooling cycle—which includes compression, condensation, expansion, and evaporation—where it helps regulate refrigerant flow. Proper airflow ...
