Dodson Heating & Cooling - Plattsburg's Licensed HVAC Services

In our area, a frozen evaporator coil is often caused by restricted airflow from a dirty air filter or low refrigerant levels. Both issues force the system to work harder, leading to ice buildup that blocks cooling. Dodson's technicians will diagnose the root cause—whether it's a simple filter change or a refrigerant leak repair—to prevent future freeze-ups and restore efficient cooling to your Plattsburg home.

For most Plattsburg homes, we recommend checking your filter monthly and replacing it every 1-3 months, especially during peak heating and cooling seasons. A clogged filter is a common culprit for reduced airflow, frozen coils, and system strain. Regular changes are a simple, cost-effective way to improve air quality, lower energy bills, and prevent major repairs.

First, check your thermostat settings and circuit breaker. If those are fine, a sudden stop often points to a safety lockout due to an issue like a frozen coil or clogged filter. To avoid further damage, turn the system off and call Dodson Heating & Cooling. Our local Plattsburg team offers prompt emergency service to safely diagnose and fix the problem, getting your comfort back on track quickly.
