HVAC TIP OF THE DAY
“Airflow Before Refrigerant — Always.”
Before you ever touch gauges or add refrigerant, verify airflow:
Clean filter
Clean evap coil
Proper blower speed
Correct static pressure
Low airflow will fake low refrigerant symptoms, leading to:
Overcharging
Compressor overheating
Premature system failure
Voidable warranty issues
✅ Diagnosis Rule:
If airflow isn’t proven first, the refrigerant diagnosis is invalid.
