Let me share the harsh truth: most HVAC failures occur because someone skipped a step. Failed to calculate the load correctly. Used cheap equipment. Got wrong the insulation needs. We have fixed dozens of these disasters. And each and every time, we remember another lesson. Like in 2017, when we decided on adding smart thermostats to each installation. Why? Because Sarah, our senior tech, got frustrated of watching homeowners waste money on bad temperature management. Now clients save hundreds yearly. https://fliphtml5.com/homepage/lweref/product-air-heating,-cooling,-and-electric/
