Why Is My Heat Pump Heating When I Want It to Cool?
When summertime temperatures start soaring, you rely on your heat pump to keep your home cool and comfortable. If warm air comes out of your vents when you put your heat pump in cooling mode, something is wrong. Here are possible reasons why your heat pump in Miramar, FL may be heating when you want it to cool and what you can do to resolve the issue.
1. Reversed Valve
Heat pumps reverse the refrigerant flow to provide heating and cooling. A malfunctioning reversing valve is a common cause for your heat pump to blow warm air when you want it to cool.
This valve controls the direction of the refrigerant flow. If it becomes stuck or fails, the system may continue to operate in heating mode even when you select cooling.
2. Thermostat Settings
Your thermostat is the brain of your HVAC system. It communicates your desired temperature to HVAC system. You might be sending the wrong signals if you’ve set it incorrectly.
Ensure the settings of your system is on “cool,” not “heat.” An incorrect mode could trigger the HVAC system to release warm air instead.
3. Dirty or Blocked Filters
Air filters play a significant role in the operation of your heat pump. They keep dust and debris at bay, maintaining the efficiency of your system.
If filters become blocked or overly dirty, airflow gets restricted. Your heat pump can’t cool your home effectively. Clean or replace your air filters regularly, especially during the cooling season.
Discovering that your HVAC system is heating when you want it to cool can be frustrating, especially during the heat of summer. However, armed with a basic understanding of the potential causes, you can take proactive steps to troubleshoot and resolve the issue.
