Before we convert temperature scales, let's take a step back and think about what temperature is in the first place. Temperature is proportional to the average kinetic energy of the random microscopic motions of the constituent microscopic particles, such as electrons, atoms, and molecules. Translation: Temperature is the average “movement energy” of the molecules in […]

Many techs may not all know what SEER exactly means or how it’s calculated, but we know that it exists, is regulated by the government, and has something to do with efficiency. SEER is the standard efficiency rating of central air conditioning systems, and its values are determined from a controlled set of testing conditions. […]

First off, I would like to say that Manual J is only as good as the information you give it, but we often run […]
