Housing assembly for an HVAC system

An HVAC system, comprising a housing assembly including:

• a casing with an air inlet and an air outlet, forming a first portion of an air conduit between the air inlet and the air outlet, the air conduit being configured to guide airflow between the air inlet and the air outlet;
• a removable cover, attached to the casing at a removable cover location and forming a second portion of the air conduit;
• wherein the casing and the removable cover form a filter slot with a cuboid filter volume,
• configured to receive a generally cuboid filter of complementary shape for filtrating the air traversing the air conduit, the filter slot including four sidewalls for constraining the filter, an inlet aperture and an outlet aperture for allowing the airflow between the air inlet and the air outlet,
• wherein the air conduit includes a guidance wall neighboring at least one of the filter slot sidewalls, the second portion of the air conduit including a part of the guidance wall;
• a heat exchanger removable from the HVAC system;
• wherein part of the guidance wall forms a side section terminating in a sidewall of the filter slot;
• and
• wherein the housing assembly is configured to enable movement of the heat exchanger towards the removable cover location during the heat exchanger removal.
