Let me share the ugly truth: nearly all HVAC failures happen because someone skipped a step. Failed to calculate the load properly. Used cheap equipment. Misjudged the insulation needs. We have fixed countless of these messes. And each time, we remember another insight. Like in 2017, when we decided on adding smart thermostats to all install. Why? Because Sarah, our master tech, got frustrated of watching homeowners waste money on bad temperature control. Now clients save 20-30% yearly.
