In a series circuit (loads connected in a row end to end), it's easy to calculate total circuit resistance because you simply add up all the resistances to get the total. In a parallel circuit, the voltage is the same across all the loads; the amperage is simply added up, but the resistance is a […]

The photo above is of a real condenser coil we cleaned just the other day. The outer fins looked OK, but dirt and lint were packed deep inside, and the head pressure and condensing temperature were sky-high. That situation illustrates that a coil can sometimes look OK at first glance but may still need to […]
