Why Is My Heat Pump Blowing Cold Air? Decoding Defrost Mode

Have you ever wondered why your heat pump seems to be blowing cold air on those exceptionally chilly days? Before you fret, let’s unravel the mystery—it’s likely your trusty heat pump is simply flexing its frost-fighting muscles!

Decoding Defrost Mode:

On frosty mornings and freezing days, your heat pump works diligently to extract warmth from the outdoor air and transfer it indoors. However, as frost accumulates on the outdoor coils, it can hinder the efficiency of this process. Fear not! Heat pumps, including those from Alien Air Conditioning, are equipped with a defrost mode to tackle this situation.

During defrost mode, your heat pump temporarily switches to an air conditioning-like mode. It redirects the warm indoor air to the outdoor coils, melting any frost buildup. This process might make it seem like your heat pump is blowing cold air for a brief period.

Should You Worry?

In most cases, there’s no need to panic if your heat pump, including; TRANE, Goodman, Rheem, Lennox, Carrier, American Standard, Amana and others, blows cold air for a short time. Defrost cycles typically last around 5-10 minutes and happen intermittently. However, if you notice prolonged periods, 15 minutes or more, of cold air or a decline in heating efficiency, Alien Air Conditioning is just a call away for a professional inspection.

Tips for a Smooth Operation:

Regular Maintenance: Ensure your heat pump receives routine maintenance to keep it operating efficiently. Remember heating can only be checked when the temperature is cold enough usually around 60 degrees which is why we recommend checkups 2x per year.

Clear Surroundings: Keep the area around your outdoor unit clear of debris and other items to facilitate proper airflow.

Contact Alien Air Conditioning: If you have concerns about your heat pump’s performance, don’t hesitate to contact Alien Air Conditioning for expert assistance.

Remember, a brief episode of cold air is often a sign that your heat pump, serviced by Alien Air Conditioning, is maintaining its efficiency, ensuring your home stays warm even in the coldest weather. Embrace the warmth and comfort provided by your reliable heating system!
