Koch Heatng & Air Conditioning - Parkston's Certified HVAC Services

In Parkston's climate, condenser coils can accumulate dirt, pollen, and debris quickly, reducing system efficiency. We recommend scheduling professional coil cleaning at least once a year, typically in spring before heavy cooling season. Our technicians use specialized tools to safely remove buildup without damaging the coils, and we can also advise on proper outdoor unit placement and vegetation management to minimize future issues.

Heat pumps in our region often freeze due to low refrigerant levels, dirty air filters, or malfunctioning defrost cycles. At Koch Heating & Air Conditioning, we first diagnose the root cause—checking refrigerant charges, inspecting filters and coils, and testing defrost controls. Repairs may involve refrigerant recharge, component replacement, or system adjustments. Regular maintenance visits help prevent freezing by ensuring all components function properly before extreme cold sets in.

We recommend bi-annual maintenance—spring tune-ups for cooling systems and fall checkups for heating systems. Our comprehensive service includes condenser coil cleaning, refrigerant level checks, heat pump defrost system testing, airflow verification, and thermostat calibration. This proactive approach specifically targets the dirty coils and freezing components common in our area, extending equipment life and improving energy efficiency by 10-15%.
