HVAC Services Saint Louis MO | Call Action Heating & Cooling STL

Yes, that's a classic symptom of a blower motor failure, a frequent issue we see in Saint Louis homes due to system strain from our seasonal extremes. The motor that circulates air through your ducts can fail due to age, dirt buildup, or electrical problems. Our technicians can quickly diagnose if it's the motor, capacitor, or another related component and provide a lasting repair to restore your heating or cooling airflow.

Absolutely. When a heat pump blows cold air in heating mode, a faulty reversing valve is a common culprit, especially given how hard our local units work switching between seasons. This valve is responsible for changing the flow of refrigerant to provide heat or cooling. If it's stuck or malfunctioning, your system can't properly heat your home. We can test the valve and related controls to pinpoint the issue and get your system back to warming your home efficiently.

Preventative maintenance is key. Our local, bi-annual tune-up service is designed specifically for the demands of the Saint Louis climate. We thoroughly clean critical components like the blower assembly to prevent motor strain, check refrigerant levels and valve operation on heat pumps, and identify minor issues before they lead to a breakdown. This proactive care extends your system's life, improves efficiency, and helps you avoid inconvenient and costly emergency repairs.
