Campbell Heating and Air | Best HVAC Repair in Portsmouth, OH

This is often due to a clogged air filter, which restricts airflow and makes your system work harder, reducing efficiency and cooling power. We recommend checking and replacing your filter monthly during peak seasons. If the problem persists, it could indicate deeper ductwork issues or a failing blower motor, which our technicians can quickly diagnose and repair.

A frozen evaporator coil is typically caused by restricted airflow (from a dirty filter or blocked vents) or low refrigerant levels. Both prevent the coil from absorbing heat properly, causing moisture to freeze. To prevent this, ensure regular filter changes and keep vents unobstructed. If you see ice, turn the system off and call us. We'll safely thaw the unit, locate the root cause—like a refrigerant leak—and fix it to prevent future issues.

We recommend biannual professional tune-ups—once in spring for your cooling system and once in fall for heating. These visits include cleaning coils, checking refrigerant levels, inspecting electrical components, and ensuring proper airflow. This proactive care directly addresses the most frequent local issues, like frozen coils and airflow restrictions, improving efficiency, preventing breakdowns, and extending your system's lifespan.
