As the warmer weather starts up along with the coming of spring, heat pumps are going to switch over from heating mode to cooling mode, probably for the first time in many months. When you first make the switch on the thermostat that will change the heat pump back into a cooling system, make sure that you check on the air flow coming from the vents. Is the air cool\u2014or does it still feel warm to lukewarm? If you\u2019re still receiving warm air from the ventilation system, it\u2019s possible that the heat pump has malfunctioned. Check again on the thermostat to make sure that you\u2019ve set it correctly. If airflow feels off or your system struggles to cool, it’s worth asking whether your<\/span> heat pump might be freezing up<\/span><\/a>\u2014a common issue during seasonal transitions.<\/span><\/p>\n

If you can\u2019t find a simple explanation for the problem, then you need to call our offices. We\u2019ll send a technician out to help you get your heat pump back in shape.<\/p>\n

It might be the thermostat after all<\/h3>\n

One common reason for this trouble with a heat pump is a thermostat that has lost its connection to the reversing valve, which is the component that is responsible for changing the system from one mode to the other. An electric signal from the thermostat causes the slide in the pump to move so it directs refrigerant a different way. If the thermostat loses that connection because of a broken wire or another malfunction, it will need to be repaired before it will work. The thermostat may even need to be replaced. Don\u2019t forget that<\/span> fall tune-ups are essential<\/span><\/a> for catching these types of connection issues before they affect performance.<\/span><\/p>\n

Or the reversing valve is busted<\/h3>\n

This is the other most common reason for a heat pump trapped in heating mode (or in cooling mode). The mechanical reversing valve can break, and the slide that alters the direction the refrigerant moves will become stuck in place. In such situations, the best approach is to have professionals remove and replace the valve. (Don\u2019t try this on your own!).
