The present invention, in various aspects, provides for a HVAC unit having at least one door and at least one part of an HVAC housing, such that the housing and door can approach one another and form a seal. Preferred embodiments of the present invention use a magnetically assisted (or resistant) door sealing mechanism to form a seal, or preferably, a tight seal, upon closure at a sealing area having a door sealing surface and a corresponding HVAC housing or other such surface, which blocks or restricts air flow in that area of the HVAC unit. By using a magnetically assisted door sealing mechanism, and, especially a mechanism at a sealing surface and a corresponding surface, a seal, and even an almost air tight seal that is resistant to opening inappropriately when air flow or pressure increases or when influenced by gravity, and can be formed while still allowing for the door to be opened, with a minimum of effort, when necessary.
