Let me share the brutal truth: most HVAC failures occur because someone ignored a step. Didn't calculate the load correctly. Used incorrect equipment. Miscalculated the insulation needs. We have fixed countless of these messes. And each and every time, we remember another lesson. Like in 2017, when we decided on adding smart thermostats to all installation. Why? Because Sarah, our master tech, got frustrated of watching homeowners burn money on inefficient temperature control. Now clients save $500+ yearly. https://www.houzz.com/hznb/professionals/home-automation-and-home-media/product-air-heating-cooling-and-electric-pfvwus-pf~1742073236
