The price depends on the configuration and installation conditions – an EKO2 specialist prepares a quotation covering equipment, works and commissioning.
Heat pump / air conditioner SEZ-M-DA
SEZ-M series air-to-air heat pumps are almost invisible, as the indoor units are installed in ducts above the ceiling.
What we check before quoting
Check duct lengths and resistance, noise at the grilles and whether the access hatch will be conveniently placed.

FAQ
Why choose an air-to-air heat pump?
An air-to-air heat pump combines three functions in one system: heating in winter, cooling in summer and air filtration. It can be fitted in an occupied home or a new build, and both the outdoor and indoor units take up little space.
It works well alongside existing heating – electric heaters, a fireplace, a stove or a gas boiler – and takes over much of the heating load in spring and autumn. Some series, such as MSZ-LN, have a more advanced filter system; see the product page for the exact features. We will match the right model to your rooms through the system finder.
Does a heat pump work below −25 °C, and does it harm the unit?
A heat pump keeps working at very low temperatures, but its heat output and efficiency fall. The exact operating limits of each model, per manufacturer data, are on the product page – e.g. MSZ-LN-VGHZ with Hyper Heating or the ZUBADAN PUHZ-SHW series. Operating limit and guaranteed capacity are not the same thing – we explain this in Heat pumps for the Lithuanian climate.
Do not switch the heat pump off during hard frosts: starting a cold system at −25 °C or below is not ideal, while continuous operation is easier on the compressor.
