While researching the topic, I realized that there isn’t as much information available on condenser motors as there is on their counterpart—the indoor blower motor. I had never really given it much thought, as I assumed that the condenser motor […]

The original tools of the trade were all analog: electrical meters, gauges, and even manometers (Magnehelic, anyone?). However, digital tools have also become a staple of the skilled trades—where would most of us be without digital multimeters? And then probes also joined the fray with the rapid improvements to smartphone technology over the last 15–20 […]
