    Why 410As a Fricken Joke....

    Well it's one of the reasons.




    There used to be a 15 ton Carrier on that curb. It's so funny it's sad.

    I hear you. I just got 2 new 25 ton carriers and they are big enough for occupancy permits!

    What's 410 got to do with it? Big units are more due to getting efficiency.

    at least the center of gravity is on the curb
    It`s better to be silent and thought the fool; than speak and remove all doubt.

    A 410a unit could actually be made smaller if it weren't for efficiency requirements.

    R410a is a more effective refrigerant than r-22 is.

    It may due to getting efficiency out of 410 because my new units are 11seer and the old r22 unit was 10.6 and they are about 3 times the size and same capacity.

    Having to split coils can be a p.i.t.a .. Are they designed these ways to gain efficiency while trying to keep unit size down? .... I recently ran a call to a store with brand new units & upon first glance they looked relatively small. When i popped off a panel & seen 3 coils sandwiched together this thought crossed my mind. Hope the guys cleaning these know to split them all lol

    Those inside coils will eventually pop out and rub the top tube enough to cause a leak.

    Happens all the time.

    I have metal clips that I use to replace the silly tie wraps that dry rot and break.

    You think that unit is more efficient than the carrier that used to be there ? We usually have to up size the breaker when going from 22 to 410a while maintaining the same seer. ( of course checking line wire for correct gauge )

    Although that's not our change out I remember the unit that used to be there.

    There is no difference in SEER.

    So explain why the manufacturer had to use twice the amount of material to build this monstrosity ?

    I remember a couple of years ago, I was trying to bid replacing a resi 3 ton unit, and the current draw of an R22 unit compared to an R410 unit. The 410 unit RLA was higher than the R22 unit for the same SEER.
    That raised a few eyebrows and even more questions.
