We will tell you why your split system may not work for heat and how to fix it. You will learn about the features of the heating of different types of air conditioners.

Optimal temperature conditions

If you think that the air conditioner works like any heating device, you are mistaken. A split system does not produce heat but transfers it from one environment to another. In the case of work for heating – from the street to the house or apartment.

The efficiency of the air conditioner depends on the temperature difference between the room and the outside. The larger it is, the worse the efficiency of the air conditioner and its performance. Each air conditioner has a minimum temperature at which it can produce heat.

Inverter air conditioners can work for heating when outside up to -20…-30 degrees (depending on the model). Normal – at a temperature of -5…+5 °C, not less. And even then, at the minimum temperature, the air conditioner will not be able to warm up the air to more than +18…+21 degrees.

How to turn on heating on the air conditioner without a remote control

Many models of split systems have an active control panel on the indoor unit. It can be touch-sensitive or ordinary, in the form of buttons. Sometimes it is hidden under a plastic cover.

If the buttons or control sensors are not visible, you need to open the front cover of the air conditioner. To do this, find grooves or protrusions under your fingers in its lower part on the right and left and pull it towards you and up (see photo).

Once the control panel is visible, it may not have an ON/OFF button. To turn on the air conditioner without remote control, you need to use a hidden button. It is located on the panel to the right of the air filter. It can be marked as “ON/OFF” or “AUTO”.

To turn it on, you need a regular pen. Depending on the diameter of the hole, reach for the button with either the stylus or the back. To turn off the air conditioner – follow the same procedure.

How to turn on the air conditioner using your smartphone

To control the air conditioner from a smartphone, it must either have a built-in Wi-Fi module or be connected to the controller. You also need to download the appropriate application for your air conditioner or controller model.

To turn on the split system to heat from your smartphone, follow these steps:

  1. Turn on Wi-Fi on your smartphone;
  2. Search the network for a controller or air conditioner;
  3. Run the application;
  4. Wait for the connection to the split system or controller;
  5. Set the operating mode “HEAT” or “HEAT”.

After that, you just have to set the desired temperature, blowing force, and adjust the blinds. If the connection with the controller or air conditioner is lost, it will continue to work in the specified mode. But to change the settings, you will need to re-establish the connection.

Why does the air conditioner not blow warm air?

If the air conditioner does not work for heating, two options are possible: incorrect setting or breakdown of the split system. Let’s take a look at them.

Some models switch to heating mode as soon as you set a high temperature, for example, +28 °C. But for most, you first need to go into the “HEAT” mode.

Each air conditioner needs 3-5 minutes to switch from cold to heating mode. New models turn off the fan and stop blowing. In older ones, the fan can continue to blow cold air around the room for some time. You just need to wait for a little.

If the outside temperature is too low, the split system will not be able to heat the air. Check in the manual or manual if your air conditioner can run on heating in such frost. If not, nothing can be done; you will have to use heaters or heat the fireplace.

If you performed the switch correctly, waited and the air conditioner did not start working on heat, several reasons are possible:

  • Not enough freon in the line;
  • The temperature sensor is out of order;
  • The outdoor unit is clogged with garbage;
  • Indoor unit dirty;
  • The fan is not working well;
  • The compressor is out of order.
