Why Proper Airflow Matters for Your Blower Motor
Your blower motor is the heart of your HVAC system — and it’s expensive to replace.
Modern ECM (Electronically Commutated Motors) can cost $600–$1,200 installed.
The #1 killer of these motors? Improper airflow caused by high static pressure or poor duct design.
Power draw spikes as static pressure rises, which means more heat, more wear, shorter blower life, and higher energy bills.
