    Condensor air flow direction

    I have a 20+ year old Chrysler AC condensing unit, model 1204-02, probably 36,000 Btu/hr.

    This has a rectangular housing, sits directly on a slab, no space beneath. The fan blade is at the top of the unit, above the coils. The fan/motor shaft is vertical, so the fan rotates in a horizontal plane.

    The two coils are below the plane of the fan, each coil assembly is parallel to and against one side of the unit, with the unit's side being made of expanded metal to allow air flow.

    Which way should the air flow through the condensing unit? In at the top, through the fan, and out horizontally through the coils and grills on the sides? Or vice versa?

    Thanks in advance.....Michael

    Well you've already paid the purchase price of a new system two times over milking that old 6-SEER unit for 20+ years. I wouldn't be proud of that fact, I'd be darned emabarrassed to tell anyone I had been so stupid. Now if you've got a 20-year old wife, well that's a different story.
    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    Holy Jesus you you should try and sell that on ebay you might find a buyer that will give you enough to replace your whole system, has that got the 440 cu in compressor or the 383 cu in. it make a difference on the fan motor you will need.

    If it is the hemi unit you will need to use this special dual capacitor setup.

    Angry Condensor air flow direction

    First, thanks to Billva for a prompt and specific response. I anticipated this.

    But what about the other 9 replies that I count so far? What did they contribute to the thread?

    I may be a newbie on this board, but….

    Is this a professional reply, Skippedover?
    “I wouldn't be proud of that fact, I'd be darned emabarrassed to tell anyone I had been so stupid.”

    And is this reply worthy of a moderator?

    Nobody asked where in the country I live, how many days per season do I use my AC, what’s my budget, what’s my cooling load, and what are my electric rates. I agree I have an inefficient system, but just saying “buy a new one” is the typical response from an AC serviceman looking to land new work – which includes the guy who connected my fan backwards.

    Air pulls through a coil a whole lot better than it pushes through. Therefore, the air should ( and will) be pulling through the coils and pushing out the top of the unit. If you put your hand over the fan, the air should be about 10 degrees warmer than the ambient temperature, depending on your unit and how it is charged and the load on the unit. I have only seen 1 model that tried to push air through the condensor coil and they went out of business years ago. I hope this helps.
