When winter hits, you should have the right information to fix all your HVAC concerns. A frozen heat pump would cause major concerns to your home and health. This is especially true during the worst of the winter season. Here are ways you can prevent it from happening and protect your loved ones. Know the common causes The best way to take on a frozen heat pump problem is to deal with it before it even happens. There are three reasons behind it, the most common of which is very cold weather. Temperatures are too low when ice starts to appear on the coils or the refrigerant lines. Another could be a lack in refrigerant. Heat pumps are more vulnerable to cold and ice when there isn’t enough refrigerant. Have an HVAC professional check it before winter comes rolling in. The third cause for a frozen heat pump is improper installation. This blocks airflow, resulting in freezing. Trust only licensed and experienced professionals to work on your HVAC system. Activate the defrosting How this works depends on your HVAC model. Older models run on mechanical timers while others might not have any at all. You can set your HVAC to begin defrosting at a certain temperature for newer units. If you want easier and better control, consider upgrading your HVAC unit.
