Gas and Oil Home Heating Furnaces - New HVAC installation

I am building a new home and I visited the site today. I noticed the copper tubing (that runs from the air cooling unit inside the home to the condenser unit outside) seems to be connected in a round about way. The inside air cooling unit is on the second floor near an outside wall. The copper tubing that joins the air cooling unit inside is run through the attic to the opposite side of the house, down the outside wall to the condenser unit outside. This run of tubing is about 70 feet long. Should the tubing be run to the condenser unit on the outside next to the exterior wall where the inside air cooling inut is located? This would make the tubing that connects the inside air cooling unit to the outside condenser unit about a 10 to 15 foot run instead of 70 feet.
Also is it true that for every foot that tubing is run from a condenser to a cooling unit, some BTU's are lost?
Any information would be greatly appreciated1
Thanks a million.

The condenser location is probably the same location as the rest of the homes built in your style on the site. If the copper is sized correctly it's not a problem. Your btu info seems incompleat. Installed correctly you will not lose any system capacity(btu's).
