There can be three reasons for this that are normal functioning:
However, if you rule out these possibilities, then a service call may be needed.
The outdoor unit fan will only run when the indoor unit is actively heating or cooling. When it’s in standby, the outdoor unit fan will stop turning.
Heat pumps sometimes make crackling, popping, clicking, gurgling, and swooshing noises. These sounds are expected for two reasons:
No, the heat pump only sends heating or cooling energy, via refrigerant, to the indoor unit through a copper tube. The indoor unit simply circulates the air in the room, filtering and cooling or heating the air while circulating it.
This has to do with the continuous operation of the fan after it has reached the temperature set on the remote control or thermostat. This occurs for two reasons:
No, there is no water in the system. However, condensation can collect, particularly when it’s in cooling mode. Some drains carry any collected water outside.
Yes, they do not use any fossil fuels or propane, only electricity.
Each situation is unique; however, the energy savings are roughly 40−60% when converting from other electric furnaces or propane.
When your system has been turned off, it can take several minutes to gather enough heat energy from the outdoor air to begin sending enough heat energy to the indoor unit and begin heating. In very cold weather, this can take as long as 20 minutes.
When in standby, the vanes will point straight out. When your system comes out of standby, the vanes will move to the position you have set on your remote control.
Usually, this means your indoor unit is in standby.
The temperature sensor for the indoor unit is located on the side of the unit itself, so it senses the temperature immediately around the unit itself. It is important to have the fan speed set high enough, and the vanes angled in a way to push the heat out into the room and away from the unit itself, given that heat rises.
No, the remote control does not have a temperature sensor in it.
The indoor unit will go into standby when the temperature sensor indicates it has reached the temperature you have set the controller to.
The answer to this question is NO if you own a multi-head system. All mini-split systems are equipped with different modes. However, when you have more than one indoor unit on the same outdoor unit/compressor, they must all operate in the same mode for the whole system to work. This also means you can’t set a multi-head system to automatic mode.
