A heat pump that’s stuck in its cooling mode can be quite frustrating to deal with. Understanding the reasons why this happens is crucial in determining the best course of action to fix the problem. Local HVAC contractor AC & Refrigeration Works highlights the possible reasons your heat pump isn’t switching to the right mode.
Thermostat Issues
You might have already set the heat pump to heating mode, only to find out that it reverted back to cooling. It’s likely that a family member tinkered on the thermostat, which is not unusual since everyone has their own idea of comfort. If this is the case for you, just switch it back to heating mode and you’ll soon notice a change in indoor temperatures.
Sometimes, the thermostat isn’t doing its intended function. All you need to do is reset it; this way, you can get it working properly again. If you think it needs recalibration or has faulty wiring, get in touch with your air conditioning repair technician as soon as possible.
Low Refrigerant Levels
One possible reason your heat pump isn’t switching to heating mode is due to low refrigerant levels. If not addressed right away, the unit won’t run efficiently, resulting in you paying more in heating costs. It is most likely caused by a leak, and must be remedied by a professional HVAC technician to prevent further damage to the system.
Dirty Filters
Your heat pump’s air filter must be changed regularly every time you use it. If it’s been a long time since you’ve done this, expect it to be clogged with debris. Excess dust and dirt on your air filter prevents most of the air from entering the system, leading to lukewarm air from the vents. Replace the filter and check if this will solve the problem. Make it a habit to do this task after every three months.
Broken Reversing Valve
The reversing valve is an important part of the heat pump because it is responsible for switching in between heating and cooling modes. It can become stuck, in which case you can free it by tapping either side of the valve body. If nothing happens, call your technician right away — it may have been broken already and must be replaced.
