hello, im interested in this hvac system, my hvac i have now is a downflow system. I see that this a multi position air handler, and I just want to be 100% sure i can use this for down flow aplication. and also, this is a 410a refrigerant?

Yes, it will work for your downflow application as ACiQ-30-AHB air handler is approved for upflow, downflow, or horizontal applications, so it can be used in a downflow setup as long as it is installed/configured correctly, and this particular model uses R-410A refrigerant.

If you have any further questions, please call us and we will be happy to assist you.
