Heat pumps transfer heat rather than create it, making them highly efficient. However, several issues can prevent them from heating properly.Dirty Air Filter
A clogged filter restricts airflow, reducing heating performance and causing the system to work harder than necessary. Replacing the filter every one to three months helps maintain efficiency.Incorrect Thermostat Settings
Verify that the thermostat is set to HEAT rather than COOL or FAN mode. Also check the temperature setting and replace weak batteries if necessary. If the problem continues, call +1 (844) 611-2488 for professional troubleshooting.Outdoor Unit Problems
Leaves, dirt, grass clippings, or debris around the outdoor unit can block airflow. Keeping at least two feet of clearance around the unit improves performance and efficiency.Common Heat Pump Problems in San Antonio

During cold or humid weather, frost naturally develops on the outdoor coil. The heat pump periodically enters a defrost cycle to melt accumulated ice. If the unit stays frozen or repeatedly enters defrost mode, it requires professional inspection.Faulty Reversing Valve
The reversing valve switches the system between heating and cooling modes. When it fails, the heat pump may remain stuck in cooling mode even when heat is requested.How to Troubleshoot a Heat Pump That Isn't Heating
