During the summer, it’s never normal to see ice built up on a heat-pump or central air conditioner, including indoor units, outdoor units, and interconnecting line sets. There is most likely a problem with your air conditioning system, and you should turn it off immediately. The ice could be caused by many factors, ranging from a broken fan belt to a faulty thermostat.
There are a number of factors that could cause your air conditioner to ice up. Depending on the issue, you may be able to fix the problem yourself. For more advanced problems, it’s vital to call an experienced technician.
You need to call a technician if your air conditioner experiences any of the following problems:
- Broken or malfunctioning indoor fan motor
- Loose, worn, or broken fan belt
- Extremely dirty blower wheel
- Low refrigerant charge
- Restricted air ducts, tubes, cables, etc.
- Blocked capillary tubes
- Blocked orifices
- Faulty expansion valve
- Stuck compressor contactor
- Faulty thermostat
- Extremely dirty or damaged indoor coil
You are able to solve the following issues on your own with proper guidance and safety precautions:
- Clogged or blocked air filter
- Blocked or closed supply and/or return vents
- Running air conditioner with windows open
- Setting the thermostat too low
It’s possible that you may see ice on an indoor coil if your air conditioner is running during very cold weather or the thermostat is turned extremely low. In these cases, the fix may be as simple as turning off your air conditioner.
Can I run my air conditioner in winter if the building gets hot while it’s still cold outside? For instance, if I have a restaurant or factory?
We recommend never turning your thermostat lower than 70 degrees Fahrenheit. If you need to turn on your air conditioner during the winter, however, we suggest installing a low ambient kit that can monitor and maintain your HVAC system’s pressure levels. This helps you avoid the complications that would arise from running a normal HVAC system.
We don’t recommend running a central or whole-home humidifier in the summer. In the State of Tennessee, running your humidifier during muggy weather wastes money and energy. Be sure that the humidifier remains shut off for the humid summer days. If your humidifier has a dampener, you should also be sure to close it while the system is off to reduce the chance of mildew and mold growth.
