This is the brutal truth: the majority of HVAC failures take place because someone missed a step. Failed to calculate the load accurately. Used incorrect equipment. Miscalculated the insulation needs. We have fixed dozens of these messes. And every time, we remember another learning. Like in 2017, when we began adding smart thermostats to every installation. Why? Because Sarah, our lead tech, got tired of watching homeowners lose money on bad temperature control. Now clients save 20-30% yearly. https://www.tumblr.com/productairheatin ... urce=share
