Learn How to Diagnose and Resolve Issues with Your Heat Pump System
Though the heat pump offers cost effective temperature regulation, even the most well-maintained machines might experience errors or malfunctions. So, if you start to have problems cooling your home during the summer, try some simple and cost effective troubleshooting techniques to get your heat pump functioning properly.
The best place to start is ensuring your thermostat is set to cooling mode and set to automatic. This should be located on the side or bottom of the machine. If this doesn’t restore proper operation, try setting your heat pump to the “fan only” mode to ensure that your fan is working. Make sure to keep the thermostat at a comfortable temperature setting, as the heat pump won’t kick on if the setting is too high.
It is also important to keep the filters clean for proper operation of the pump. While it is generally advisable to change the filters around monthly, you should definitely do it if your system is experiencing difficulty cooling. To ensure that debris isn’t blocking the compressor, use a low pressure hose to wash away any dirt when cleaning the filters.
If your heat pump is running but is not cooling, check to make sure that the battery in your electronic thermostat isn’t low. Replacing a battery is a simple fix, and could be all your system needs to restore its functions. Ice buildup on the unit can be a common cause of malfunctions, and the energy efficiency settings might not provide the machine with the necessary time to clear the unit. To melt the ice, simply run the “fan only” setting for an hour or two. Alternatively, you can try to move the outdoor sensor to a more ideal location, like closer to the coil’s outtake.
If all else fails, it might be time to call in a qualified electrician to take a look at your heat pump. They will be able to determine if the issue is connected to the compressor or if your wiring needs to be updated. Keep in mind that, according to the EPA, only licensed professionals should be allowed to handle refrigerants. As refrigerant uses synthetic materials that are hazardous to both humans and wildlife, they are strictly regulated.
In conclusion, troubleshooting a malfunctioning heat pump often requires a process of elimination. By testing the fan, regularly changing filters and checking the battery on your thermostat, you can often identify malfunctions and take steps to correct them. If the issue is more serious, it is important to keep safety in mind and contact a professional for assistance.
