Discovering that your heat pump is not blowing hot air can be frustrating, especially during colder months. A functioning heat pump is important in maintaining indoor comfort, especially in seasons of extreme conditions. Here are some possible reasons why your heat pump may not be blowing hot air.

Thermostat Settings

Ensure your heat pump settings are set to the correct heating mode and the desired temperature. Sometimes, a simple adjustment to the thermostat settings can resolve the issue.

Air Filter

Dirty or clogged air filters can restrict airflow and hinder the performance of your heat pump. Check the air filter and replace it if it appears dirty or blocked. Regular air filter maintenance is essential for maintaining function and preventing airflow issues.

Refrigerant Levels

Low refrigerant levels can impair the heat pump’s ability to transfer heat. If your heat pump is low on refrigerant, it may struggle to produce hot air. Contact a professional HVAC technician at A/C King Inc. to inspect and recharge the refrigerant levels if necessary.

Outdoor Unit Issues

Problems with the outdoor unit, such as a malfunctioning compressor or fan motor, can prevent the heat pump from generating hot air. Inspect the outdoor unit for any signs of damage or unusual noises. If you notice any issues, schedule a service appointment with A/C King Inc. for professional diagnosis and repair.

Defrost Cycle

During colder weather, heat pumps may enter defrost mode to remove frost or ice buildup on the outdoor coil. While in defrost mode, the heat pump may temporarily stop blowing hot air. If you suspect that your heat pump is in defrost mode, wait for a few minutes to see if hot air resumes once the cycle is complete.

If you’re unable to resolve the issue on your own, don’t hesitate to contact A/C King Inc. for professional assistance. Our experienced technicians will diagnose the problem and provide prompt, reliable solutions to restore your heat pump’s functionality and efficiency.
