When we install systems, we should have three main goals in mind: maximizing longevity, efficiency, and capacity. We want our units to work as long as possible, use the lowest amount of energy, and move the greatest amount of BTUs possible with a proper mix of sensible and latent heat transfer. Unfortunately, some installation practices […]

In our line of work, it's all too easy to let your bad experiences inform your present and future experiences. That is especially true if you have a high emotional range.

I wanted to circulate the air and keep air moving through the high-efficiency air filter that most of our houses had. Later, I […]

Ohm’s law is pretty straightforward; you multiply ohms by amps to get the voltage. Using variable E to represent voltage, variable I for amps, and variable R for ohms, the equation for Ohm’s law looks like this:  E = I × R  You can figure out the number of amps in a system using basic […]
