AC in Back Yard
All,
Unfortunately we hired a junior/inexperienced architect and they placed the ac in the rear yard, approximately 10 feet from the sliding door opening. When speaking with the GC he said i wouldnt be able to move it to the end of the rear yard b/c it would create more load for the hvac due to the increased line. Any one have a suggestion or ideas on this?

we ran our LGs to the absolute limit for supported ft line (and maybe a little above). We have seen no notable problems in doing this in 2 years of use. We unfortunately didn’t go the branch route, which I would have preferred due to the reduced number of lines in the garden which are an eyesore.

We do them in the back corner quite often, like Eman says, with the branch box, when the distance is too great, and have not had any problems with them this way.

Steve sheets talking about the distance from the line set length from the out door unit to the indoor heads… hopefully the equipment has not been purchased and the specs can be changed. Switch to a Mitsubishi unit going to an indoor branch box. From there you should be able to reach all the indoor heads while keeping within specs.

when you say more load for the HVAC, i assume you are referring to electric? did the GC consult an (or his or her) electrician about this or is the GC saying this on his own? Yes, there is voltage drop when wire is run for longer distances (this can be overcome by using a heavier gauge wire). i would run this by someone who works with mechanical/hvac systems or a licensed electrician. I am sure there are GC’s who can run these calculations (you or i could figure it out with a book in front of us; there are even tables to help calculate wire size vs run) but it is really in the electrician’s wheelhouse.
