Performed ac diagnostic granite bay. To figure out what going on with none functioning system. Previous company’s tech left system torn apart. Will need to replace some parts and then try system. We need new squirrel cage, new motor, new motor bracket. Then need to re attach everything since it’s disassembled... and it’s a down flow. Flue needs to be reattached. Unit then needs to be re wired up. Once all that is done we can fully test to see if anything else is going on. Won’t know until then, could be something else going on as well. Recommend looking at replacement options due to age and shape of equipment. And that Parts will have to be shipped in, takes time.
