Here's the brutal truth: the majority of HVAC failures happen because someone ignored a step. Failed to calculate the load properly. Used cheap equipment. Misjudged the insulation needs. We've fixed hundreds of these messes. And each and every time, we file away another lesson. Like in 2017, when we started adding smart thermostats to every installation. Why? Because Sarah, our master tech, got sick of watching homeowners waste money on bad temperature management. Now clients save 20-30% yearly. https://www.vpiindustries.com/group/vpi-general-forum/discussion/d2092ebb-3242-4f3e-901e-be82d38a5a04
