A couple questions:
1. Can a standard heat pump accommodate MERV 13 filters without modification? (Can it handle the pressure drop?) What do you think about older heat pumps - will they be able to handle this additional pressure drop without issue generally or did older heat pumps generally have smaller fans?
2. Do bipolar manufacturer's have any response to why Ashrae has not yet recommended them?
As an equipment vendor - how do you think DX will handle this recommended oversizing? (+50% OA)
So if you have a two stage system, can you handle this amount of oversizing without humidity issues or do you essentially need to go fully modulating on the DX side?
