HVAC Services Maryville TN | Call Airco Heating & Air Conditioning

Yes, a clogged air filter is one of the most common causes of poor cooling performance in our area. A dirty filter restricts airflow, forcing your system to work harder, reducing efficiency, and potentially causing the evaporator coil to freeze. We recommend checking and replacing your filter monthly during peak seasons. If a new filter doesn't solve the issue, it's time to call Airco for a professional diagnosis to check for other problems like refrigerant levels or a failing component.

This is often a sign of a faulty reversing valve, a critical component that switches your heat pump between heating and cooling modes. When it gets stuck or fails, the system can't change modes properly. This is a common repair need for heat pumps in our climate. Our technicians at Airco are experts at diagnosing and replacing reversing valves to restore your home's warmth efficiently and correctly.

We recommend professional maintenance twice a year—once in the spring before cooling season and once in the fall before heating season. This proactive service is crucial for our local climate. It includes cleaning critical components, checking refrigerant levels, testing the reversing valve operation, and ensuring all electrical connections are secure. This routine care by Airco can prevent common breakdowns, improve efficiency, and extend the life of your system.
