The definition of a transformer is a device that changes the voltages in an alternating current circuit. You may have heard of an autotransformer or a buck-boost transformer, and these terms are usually used for the same type of device; they just highlight different aspects. A transformer does not need to be a buck-boost to […]

Before we get into the parts that will ruffle some feathers, let's talk a bit about what a “Start” capacitor is and what it does. First, let's review that both start and run capacitors connect between the leg of power opposite of compressor common and the start winding. Even though it seems like a run capacitor […]

Old-timers always used to say that running plumbing and condensate drains wasn't rocket science because “water flows downhill.” While that may be true, water also floats in the air, goes uphill, and forces its way through concrete. Here is a look at some of the ways that water moves that impact building comfort and integrity. […]
