Here's the harsh truth: the majority of HVAC failures happen because someone skipped a step. Did not calculate the load properly. Used cheap equipment. Got wrong the insulation needs. We've personally fixed dozens of these messes. And every time, we file away another lesson. Like in 2017, when we decided on adding smart thermostats to each installation. Why? Because Sarah, our master tech, got frustrated of watching homeowners waste money on bad temperature settings. Now clients save hundreds yearly. https://us.enrollbusiness.com/BusinessProfile/7668666/Product%20Air%20Heating,%20Cooling,%20and%20Electric
