Ill give you a number when i get home mate to contact them. They did a good job on my house which involved installing ducts and talking with builder during construction becuase it was two 2 story and needed penertrations into the slab etc.
all came out great. And price was good I got quoted 16k got them down to 13k and then at the end i gave them cash and got it for 11k. so i was stoked.
