Hi , I am new to the forum ,,, and this is my Very first post ....
i have a pre installation piping ruining through the floor and walls for a 18000BTU 2.25HP Sharp Ac , 2 month later i had a contract with other company to bay the machines to instal it ... there technician told me that the space is large for the 18000 and i had to use the 24000BTU , 3HP unit ,, and i told him that the piping was made 1/2inch ,,,, he told me no problem we can use a 5/8inch adapter and weld it with the original 1/2 pips ...My question now .. is this setup is OK ? or will it effect the compressor or the cooling efficiency ? cos iam using a smaller diameter long pips 8 to 11 meter ? ...Thanks
