The hottest day of the summer is not the time for your heat pump to stop working. You inspect your heat pump and notice that it is frozen.

Unfortunately, this is a common problem that can occur even in the summer. There are a number of things that can create frost on your heat pump, specifically on the outdoor unit (compressor).

Here are some explanations that may help you better understand this phenomenon:

• Reversible valve malfunction
• Leak or lack of refrigerant gas
• Malfunction of the fan in the ventilation cabinet
• Defrost card defective
• Defrost sensor defective
• Dirty or clogged filters
• Outdoor coil clogged with debris

What to do if your heat pump is frozen:

• When you notice that your heat pump compressor is frozen, turn it off and let it thaw completely.

• When your heat pump compressor is completely thawed, check the airflow and clean and/or replace the filters. This may partially solve your icing problem.

• If freezing problems continue, even after cleaning and replacing your filters, call a professional right away. Freon leaks, larger air leaks or other problems require professional attention. Do not attempt to do the repair yourself. A certified technician will find the problem and fix it quickly.
