Did not calculate the load accurately. Used incorrect equipment. Got wrong the insulation needs. We've fixed hundreds of these failures. And every time, we record another learning. Like in 2017, when we began adding smart thermostats to each system. Why? Because Sarah, our master tech, got frustrated of watching homeowners burn money on inefficient temperature settings. Now clients save hundreds yearly. https://www.b2bco.com/productairheating</blockquote><br> Annuler
