    During the warmer months it works as an air conditioner; when it is cold, it reverses the action and uses the inside coil to release heat. So, 1 unit is both a heater and cooler.

    How does the inside produce heat?

    By using the outside coil to absorb heat (refrigerant in condensor coil is colder than ambient when in heating mode making it act like an evaporator coil), then that refrigerant is put under higher pressure which raises the temp, and it gives up heat though the inside coil (which acts like a condensor coil during heating).

    Heat pumps do NOT produce heat.
    As the name implies. They pump, move heat from one area to another.

    Even when its 20°F below 0, there is still heat in the air.
    The refrigerant gas absorbs some of this heat, and then combines it with the heat of compression (from the compressor) and PUMPS it into the indoor coil.
    Where the blower (of an air to air heat pump) blows cooler house air across the now warmer inside coil.
    The cooler air absorbs this heat, and it is distributed to your home via your duct system (yes some mini splits don‘t use duct work).

    It works the same in cooling mode. It just pumps/moves the heat of the indoor air to the outdoor air, instead of into the home.

    Modern conventional heat pumps can maintain a high efficiency at much lower outdoor temperatures then heat pumps of just 10 or 15 years ago.

    How many times must one fix something before it is fixed?

    Much better than my simplified explanation. I'm not always that great at condensing a complicated subject to a short, easy to understand Readers Digest version.

    I think it took me longer to think how to say that, then to type it.

    Do a search on YouTube for heat pump operation. Some good informational videos on there!
