What to do if my Ecoer Heat Pump system cannot cool well?

  If your Ecoer Heat Pump system isn't cooling well, several factors could be the cause. It could be due to high or low outside temperatures, which activate a normal protection control to limit RPS. Other potential causes include a dirty air filter or a blocked outlet of the indoor unit (in which case you should replace the air filter and remove any obstacles), too little refrigerant in the system (check the refrigerant amount or for any leaks), or a blocked refrigerant in the condenser coil (counterclockwise the TXV, ensuring the refrigerant coefficient is 0.6).

  If your Ecoer Heat Pump system isn't heating well, several factors could be the cause. If the outside temperature is too low and there's no third-party heat inside, install auxiliary heat for backup (dual-heating is recommended). Other potential causes include a dirty outdoor coil (clean the outdoor coil), a dirty air filter (replace the air filter), lack of refrigerant (check refrigerant amount or any leaks), or using micro channel coil in heating (no micro channel coils shall be used for heat pump).

Why does my Ecoer Heat Pump system not start-up but the digital tube shows normally?

  Charlotte DavisAug 21, 2025
  There are a couple of reasons why your Ecoer Heat Pump system might not be starting up even though the digital display appears normal. First, check that the Y/O/C wirings are correctly connected and that the cooling/heating setting temperature from the thermostat is properly set. Second, the thermostat might be incompatible; try using other traditional 24Vac thermostats.

Why does my Ecoer Heat Pump system operate mode reversely?

  If your Ecoer Heat Pump system is operating in reverse mode, it is probably due to an incorrect O/B signal selection. Choose 'O' for cooling from the thermostat.

  If your Ecoer Heat Pump isn't cooling effectively, several factors could be the cause. The outside temperature might be too high, triggering normal protection controls. Alternatively, the outside temperature could be too low, so you should ensure the cooling loads. A dirty air filter or blocked duct can also restrict airflow; replace the air filter and clear any obstructions. Low refrigerant levels or a refrigerant blockage in the condenser coil could also be the reason. In the latter case, counterclockwise the TXV, ensuring the refrigerant coefficient is 0.6. Finally, check for refrigerant leaks and replenish if needed.

  If your Ecoer Heat Pump is struggling to heat, it could be due to several reasons. If the outside temperature is too low and there's no third-party heat source, consider installing auxiliary heat for backup. A dirty outdoor coil or one covered in heavy snow can also reduce heating efficiency; clean the outdoor coil in this case. Also, replace the air filter if it is dirty. Ensure that micro channel coils have not been used for the heat pump, as they are incompatible. Finally, check for refrigerant leaks and replenish if necessary.

  If your Ecoer Heat Pump's digital display appears normal but the system won't start, there are a couple of potential causes. First, check that the Y/O/C wirings are correctly connected and that the cooling/heating setting temperature on your thermostat is properly set, ensuring there is 24 VAC for the Y signal from the thermostat. Second, your thermostat might be incompatible; try using another traditional 24VAC thermostat.

  If your Ecoer Heat Pump is operating in reverse mode, the issue is likely due to an incorrect O/B signal selection. To resolve this, choose 'O' for cooling at the thermostat.
