About Magic-Pak HVAC Systems
Owned by Lennox International
Magic-Pak has built through-the-wall, all-in-one heating and cooling units for decades and is now part of Allied Air Enterprises, a Lennox International division. Instead of a separate indoor furnace and outdoor condenser, a Magic-Pak puts the whole system in one slim cabinet that slides into a sleeve through an exterior wall. There is no rooftop equipment and no ground-level condenser, which is why the units are so common in apartments, condos, senior living, and light commercial buildings.
Because Magic-Pak is an Allied Air brand, the equipment is built in Orangeburg, South Carolina alongside other Lennox International lines and uses the same serial number system. The first two digits are a plant code, the next two are the year of manufacture, and the fifth character is a letter for the month.

Known Magic-Pak Issues to Watch For
A short list of patterns reported on Magic-Pak equipment. Most have been addressed with revised designs or service bulletins, but they're useful context if you're diagnosing an older system.
- •Because heating and cooling share one cabinet, a single failed component can knock out both at once, unlike a split system where the parts are separate.
- •The wall sleeve and exterior grille can let in air and water once the gaskets age, so reseal them during service to avoid drafts and leaks.
- •A replacement unit has to match the existing wall sleeve size, so confirm the sleeve dimensions before ordering a like-for-like swap.
