Ducted vs. Cassette Heat Pump Minisplit
In the early stages of a gut remodel and addition on a 2 family home with identical units and trying to get a general idea of placement and types of units to recommend to the GC.
Before the remodel the units were heated with a 30K LG system, LMU300HHV and 3 wall mounted indoor units. I had these systems refrigerant recovered and stored for possible re-use.
The new construction increases the size quite a bit, but I have had a manual J done and because of the new spray foam, windows , etc, the requirements stay the same at under 30K per unit.
If I try to re-use the LG units, I would have space to add one more head, as there is a max of 4 heads, but I am not sure how I can get one head to cover the remaining areas which are titled “new living room, new dining room and kitchen” in the attached plans.
Would a cassette unit in the ceiling possibly cover these areas or should I go with a ducted unit? Rooms are approx 13.5×13.5 and 15×26
I’m also considering trying to hire a HVAC designer to do this, but it seems most consultants are used to working with traditional ducted design as opposed to mini splits.
