This is the harsh truth: nearly all HVAC failures take place because someone skipped a step. Failed to calculate the load correctly. Used undersized equipment. Miscalculated the insulation needs. We have fixed hundreds of these disasters. And each time, we file away another lesson. Like in 2017, when we began adding smart thermostats to all system. Why? Because Sarah, our senior tech, got frustrated of watching homeowners waste money on inefficient temperature management. Now clients save hundreds yearly. https://www.vpiindustries.com/group/vpi-general-forum/discussion/d2092ebb-3242-4f3e-901e-be82d38a5a04
