Your unit is a Magic Pak built by Armstrong (aka Allied Air). Your unit is completely self contained. The Compressor and Coil are located in the bottom portion of your unit and should be serviceable by sliding the lower chassis out.

Thanks for that info,
In order to service it,do I have to remove gas pipe line?
The chassis won't slide because the gas pipe attached to the whole furnace,
The only thing I can see it by removing sliding door then you will see the air filter and behind it is the coil .So you said compressor is beside it ?
Where is the filler for freon ?
Where is the blower located?
Do I remove the front panel to see that blower? Or the side panel?

LOL... Have fun.

Its classified as a small appliance containing less then 5 pounds of normal operating charge. So the factory doesn't put any access fittings on it, for checking the charge.

The compressor is behind and to the right of the coil you see. Should be a small plate above teh coil, with several screws in it. You need to remove them. And to pull the molex plugs open. Then the heavey A/C chassi pulls out. Be very very carefull. they ain't light. As a matter of fact. that is 70% of the weight of the unit.

PS: Don't forget to disconnect the drain line before pulling the chassi. Or you'll damage teh drain stub of the unit.

Beenthere is absolutely right. The Magic-Pak is not for the faint of heart or ability :no:. The company I currently manage is the wholesale distributor for the Allied Air line and I have seen very capable contractors struggle with these things.

This is not like a split where you have something sitting outside and sitting inside. This is a unit that is designed with the architecture of the building, so you stand a great chance of multiple issues if not properly serviced or handled.

I am a huge proponent of DIY, but I would leave this one to the pros.

Good Luck.

I'll bet this guy could help...

Still can't see that blower from the picture .they said to able to service that blower ,must pull out the whole chassis .will this cooling box slide out and leave the heating unit intact.?,I just want to know if that's the procedure to remove it.
Why they made this thing so hard ?
How do you clean the blower if you can't see it?
Any video would help or time for pros

The chassie pulls out. they made it that hard. because architects and builders wanted a unit they could stuff in a super small tight area. So they could charge people more for the extra 3 sq ft of living space they get with those units.

So true. The Skymarks are a lot easier to work on but have only been around for 10 yrs or so. Armstrong has the same unit from 20 yrs ago. The rest went kaput Ie:Fedders.
