Can I Mix Brand Units Together? - Ask The Expert Episode 297
Today's question comes from Steve H.
"Hey Dan. Can I use a MRCOOL air handler with an LG Multi F Max inverter heat pump? I will have 5 LG air handlers. Plus, would also like to integrate this MRCOOL air handler."
You can if you want, but there is a chance that mixing units will void any warranty you have. Plus if they cause issues, it will be much harder to solve the problem.
So for best results, don't do it.
