It is a frustrating winter morning when you expect warmth, but your vents are blowing chilly air instead. Before you panic about a total system failure, it is important to understand how your heat pump operates. At Total Air Systems, we want to help you identify whether you face a simple fix or a serious repair.
Check Your Thermostat Fan Settings
The most common culprit is often the simplest. If your thermostat fan is set to "ON" rather than "AUTO," the blower will run continuously even when the heating cycle has ended. This moves unheated air through your home. Ensure your settings are on "AUTO" to guarantee air only moves when it is being heated.
Inspect for Clogged Air Filters
Restricted airflow is a major enemy of home heat pumps. A dirty air filter blocks the air your system needs to transfer heat effectively. When airflow is choked, the system can overheat and trigger a safety shutdown of the heating elements while the fan keeps running. We recommend changing your filters every one to three months.
The Defrost Cycle is Running In Volusia County
Humidity can cause frost to build up on your outdoor unit. Your heat pump is designed to automatically enter a "defrost mode" to melt this ice. During this brief cycle, the unit temporarily reverses and may blow cooler air inside. This is a normal part of operation and usually resolves within minutes.
Potential Refrigerant Leaks or Component Failure
If the air remains cold, you may be dealing with a refrigerant leak or a faulty reversing valve. These components are vital for moving heat from the outdoor air into your home. Low refrigerant levels prevent the system from reaching the necessary temperatures, requiring professional heat pump repair or a potential heat pump replacement to restore your comfort.
