No, you need to order the correct kit from the get-go e.g. the right amount of air handlers and line sets – if you wish to order additional line sets, couplers or accessories we can supply those locally.
We do not recommend ordering partial kits as full kits are discounted. These items are drop shipped from our warehouse, so it is more cost-effective to send everything together on one or two pallets. You don’t have to install the additional air handlers immediately as long as you fit 50% or more of the condenser’s capacity e.g. 36K condenser = air handlers 9K + 9K.
