Moving a heat pump


I have a Comfort Maker Softsound 1200+ heat pump and it is about 10 ft from the furnace. I am putting an addition onto my house and need to move the unit another 18ft. Is that ok or is that two far away for the copper line. All together it will be approx 30ft. Any help is appreciated.

I would say probably but I'll defer to the HP guys here

No problem that sounds well within the limatations. Assuming this is a normal basement to yard setup and not having a larg lift for example ground to a 3rd floor airhandler or something.

I am in the Chicago area with 26 years exp. I don't do a lot of heat pumps but enough to know the basics. I run a dual fuel in my own home.

No problem with the extension. 50 ft is not uncommon. Your installer will of course have to add additional refrigerant charge to cover the added length in order to attain correct pressures.

btw...Dual Fuels are a great idea

Good Luck

Depending on the actual size of the unit and air handler, the manufacture may recommend to increase the size of the lineset from the air handler and heat pump.

On my system, the break point was 25' from the air-handler.

No problem with going from a 18 to 30' line set.
With possible exception that it may need a larger vapor line.

Also. Have the contractor run a new line, instead of just extending the current one.
This eliminates a possible joint leak in a crawlspace, or hard to get to area, later down the road.
