Tech Tips:
Windows might seem like the builder's problem, but they play a big role in what we do every day. Poorly designed windows can spike heat gain in summer or loss in winter, messing with load calculations and forcing HVAC systems to work overtime. That leads to uneven comfort, higher bills, and more service calls. Getting […]

First, let's state the obvious and clear the air a bit. The photo above is SUPER CHEESY! But this story is about three bad techs who don't know it, so a photo of three models clearly posing in clean clothes makes as good a proxy for a bad tech as anything else. First off, I'm not […]
