This is the ugly truth: most HVAC failures occur because someone skipped a step. Didn't calculate the load accurately. Used undersized equipment. Got wrong the insulation needs. We have fixed hundreds of these messes. And each time, we file away another learning. Like in 2017, when we decided on adding smart thermostats to every system. Why? Because Sarah, our master tech, got frustrated of watching homeowners waste money on bad temperature control. Now clients save hundreds yearly.
