Mini Split Heat Pumps

[Beth Cannon]

Considering installing a mini split heat pump in one of my SFR. The house is 900 sq ft. Currently a 2 bedroom but will be converted to a 3 bedroom at next tenant turnover. Anyone have any experience with this type of system? Pros and Cons?

They make multizone units.   an HVAC contractor bid and tried to price two single units (at twice the installation cost of one)    

The way I am going to set up mine with a single outside unit with two interior units (dual zone).  

- One interior unit will be 12,000 BTU for a large living room/kitchen space, and a smaller 9,000 BTU for the bedroom.

the total system capacity has to be able to cool both inside units at the same time so 21,000 BTU or larger for the outside unit.

The beauty of these is that they can be installed DIY (provided you get your 608 certification card), as long as the line sets don't need to be shortened or lengthened, as there is no brazing/welding involved, just connect the lines and purge air, etc.

my dual zone costs comes in at around 2.6k to 2.8k for my 800sqft structure.
