What sizes do they come in – what if I need more than 25′?
Single Zone systems come with a standard 25′ length – this is not exchangeable as it comes pre-packaged – these can be extended by purchasing additional 16′ | 25′ | 35′ | 50′ sections & coupler kits.
Note: The coupler kit – includes an additional length of communication wire to extend the line between the air handler to the condenser’s electrical panel.
Multi-Zone systems are flexible and come with a choice of 16′ | 25′ | 35′ | 50′ line set lengths – so using a combination of these you’ll be able to get close to the total length you’ll need.
