With Milton, FL’s summer heat continuing for a few months still, few things can be more frustrating than to see your heat pump release warm air while it’s in cooling mode. Unfortunately, this is not only annoying but also indicative of deeper trouble. Here are a few reasons why your heat pump might be blowing warm air while it’s in cooling mode.
Reversing Valve Issues
If your heat pump is pushing out warm air when it should be expelling cold air, the most natural place to look is its reversing valve. To make both their heating mode and cooling mode functions work, heat pumps need the ability to make refrigerant flow in opposite directions at different times. The reversing valve is the component that makes this possible.
Sometimes, however, the reversing valve may freeze in place, stuck in its heating mode position. An HVAC technician can repair the valve, replace it, clean debris out of it or do whatever else is necessary to return it to normal.
Debris Causing Obstructions
Air must flow smoothly if your heat pump is to cool your home effectively. However, dust and debris often finds its way into the system and clogs the passages through which air passes. Most frequently, dirt and dust simply accumulates on your heat pump’s filters and restricts airflow.
To prevent this, you need to clean or replace the filters every one to three months, depending on conditions in your household. An HVAC technician can clean out debris from other areas during preventive maintenance.
Refrigerant Leaks
Your heat pump uses refrigerant to extract heat from the surrounding air and cool your indoor environment. If enough of that refrigerant leaks out, though, the system will no longer be able to generate cold air. During the summer, this might mean that nothing but warm air will come out.
Never to attempt to replace refrigerant on your own. Always leave this work to the professionals.
