    High Efficiency Heat Pump Condensing Unit Height

    It seems like most 4 ton 18SEER heat pump condensing units are 44" tall or even taller, which presents a problem when you are installing below a window, although Amana, Goodman and Rheem are 38" tall or less. I know the new units are pretty quiet, but who wants to look out at a condensing unit?

    Rheem's top unit is 33" tall in a 4 ton. If in a cold climate, add for pump ups. But if you want efficiency you get size!

    after paying good money for it I would it does create a problem some times although most times you can move it a couple of feet one way or the other, I have also completely relocated them

    In my case, relocating or moving a meter L or R may not work out. I guess Goodman's 5mm SmartCoil technology makes for a shorter condensing unit.

    Those units are the same size as before smart coil. It's not in 4 ton 18 seer. Anything in the 18 seer goodman/amana line is freaking fat. especially 4-5 tons.

    Fix the house, put in a 2 ton. It'll be a lot smaller, quieter, more comfortable and smaller energy bills.

    Post pics of air handler, you may be surprised to find you don't really have 4 tons of airflow.
    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    DO THE NUMBERS! Step on a HOMESCALE.
    What is comfort? Well, it AIN'T just TEMPERATURE!

    Energy Obese? An audit is the next step - go to BPI.org, or RESNET, and find an auditor near you.

    I thought the whole Amana/Goodman 18 SEER 3, 4 & 5 ton line are 35" W x 35" D, which is pretty standard amongst all mfrs, except for maybe Rheem?

    Yeah, their 35x35. Which is freakin huge. I dunno if thats standard across mfgs.

    Their not smart coils though.

    Just from a casual and not a scientific observation, but the Amana/Goodman footprint and skyprint is one of the smallest. Does size matter when it comes to HVAC units?

    Bigger is always better!

    Actually there are several ways to improve efficiency. A bigger coil is one of them. Or you can make a 2 row outdoor coil, with one coil inside another coil. That makes the outdoor unit smaller again. But the space between the coils can collect dirt, which can be hard to clean out.
    Remember, Air Conditioning begins with AIR.

    At what point does aesthetics factor into the equation or does size trump appearance?

    At what point does initial cost outweight efficiency? It all depends on manufacturer.

    I'll give you one further. At what point does the cost of manufacturering the equitment outweight the size of the unit?

    Imagine cell phones. Condensing all that technology into a smaller phone usually costs more than the big ones.

    They could probably make a small 18 seer 5 ton unit, but the cost of making the unit would greatly outweigh what a customer would be will to pay, just for aesthetics.

    So, in reality, the driving force to the size, is YOU! Goodman's study groups have probably shown that given their current price structure, a person would accept a unit X by X, at X efficiency, at X tonage.

    That was a logical post... just look at the mini splits
