View Full Version : split or dual pack? Which is more efficent?
08-09-2006, 02:53 PM
Building a new single story 2200 sf house. Area is typically low humidity and sees maybe 40' in winter, up to over 100' in summer. Is a split system better than a dual-pack? I was thinking it would be better to keep the condensor on the ground where it is cooler, and keep the furnace/evap in the attic out of the weather. Does the long run of piping hurt cooling efficency? Any ideas? Thanks.

no package unit i know of can reach the efficiencies of a high end split system.

we run freon lines up to attic everyday. no matter what the loss is, and it shouldn't much,the gains far exceed spend your light fixture money on hvac and upgrade to a good system.you can,t see it,but you know when you're comfy and you know that power bill comes every month.

with your hot temps you may want to consider the split, as high efficiency will benefit you in the long run.
as far as i know a package system will at best be 12 seer (could be wrong)
contact a couple of local pro's, for their pros
and cons, or if you give an area, someone here may be able to help.

15.2- 16.05 seer. should be elegible for part of the federal tax credit.
i stand corrected, again.

If possible, design the house so that the equipment and the ducts are located inside the conditioned area. This will save you lots of money in the long run since there are no ducts in a 140* attic picking up heat.
If you do locate the equipment in the attic, just make sure that the duct system is insulated and sealed really well. You don't want to be sucking 140* air into your system, or blowing cold air into the attic.
You should (or have someone else) inspect the duct system regularly to make sure that it is in good shape.
