This is the ugly truth: the majority of HVAC failures happen because someone skipped a step. Failed to calculate the load accurately. Used undersized equipment. Miscalculated the insulation needs. We have fixed dozens of these failures. And each time, we file away another lesson. Like in 2017, when we decided on adding smart thermostats to each system. Why? Because Sarah, our master tech, got tired of watching homeowners lose money on poor temperature management. Now clients save 20-30% yearly. https://forum.prestashop.com/profile/1995385-productairseattle/?tab=field_core_pfield_19
