Then it will be backwards, then you will also have to install the condenser backwards
to match the evaporator coil being backwards.

But will the fan be turning the right way then?


Or Not.

Have you had good luck with the condenser facing backwards?

15 posts, no problem. I have a feeling I'm going to be a regular here. has anyone had problems with the coil in this configuration? Seems it would be fine, but since there is a large audience; the more info I get the more I know and the better I can do. Thanks again all.

There's no problem with facing the coil opposite of the furnace. As long as there is good access should a problem arise with the coil it's not a problem at all.

That is what I was trying to say. We stress the envelope and in apartment basements, we put 'em in backwards, so we don't have to undo the metal flues and can easily lift up the skirt and check for evap blockage.

Thank you! We may turn it around anyway just so we can establish exactly 15 feet of line set. Since I am getting such good feedback, whats the chances of a condenser that is charged for 15 feet of line set, to have enough for 17 feet?

Zero chance but it'd be a very minimal amount to add, about as much as you'd lose out of your high side hose when disconnecting it from the system. Read the install manual it will tell how many oz./ft over 15ft to add, somewhere around .67oz/ft over 15. It may tell you to add for oversized coil or txv vs fixed orifice etc etc. always read the install manual if you aren't familiar, lots of good info in there.

I'm thinking, half an ounce?

You'll have to buy a new condenser rated for 17' of line set

Really. Yank another chain!

1.3ish oz.

1.3ish oz.

I was thinking one foot. Seventeen minus fifteen equal two. There's my error.

Just easier to put the condenser two feet closer. But, yeah thanks for the tip; I have the manual online in PDF and have been reading it on lunch. That's how I came to my original concern of having the coil facing the back of the furnace, because it actually specifies in the manual to put the coil facing to the front of the furnace, so naturally I went looking for information.

Thank you all for you help! Have a good night.

Some things to pay attention to when doing this

There shouldn't be a problem doing this....... airflow is airflow.

Get a level, a lot of contractors slope the furnace from back to front .....if this is a 90% for example.

Make sure your coil will drain properly and not spill off of the back of the drain pan.

Follow the instructions and use a trap in the condensate line, some guys don't.
