Ductless mini split systems

Brian_48

I've been trying to gather ideas on how to overhaul the horrific forced air system my house has now. I asked for ideas on another website and heard everything from baseboard heat, to nat. gas wall unit, to the ductless mini split systems.

I did some internet exploring on the DMSS and they don't seem overly expensive or difficult to install. Most seem to be for A/C, but some have a combination "heat pump". How does the heating side of these work? Do I need a well? Can anyone give me feedback on the pros and cons of using them? My hope is to use these for both heating and cooling, but I don't know how effective or efficient they are. My house is only 800sf on the first floor and 350sf on the second.

Depends

Depends on where you live..The new heat pumps are very efficant since they just move heat..But only work well if the outdoor temperatures don't drop lower then say the mid 40's...

They use electricity ,so electric rates should be compaired to other fuel options and prices in your area....

P.S. I found mini splits are like bath room exhurst fans.. The higher price ones are quieter........

I live outside Detroit, and it definitely gets well below freezing Dec -> Feb.

Ductless would be questionable

The temperature range on the better ones I've seen only go down to about 15 above zero then you have to rely on your backup heat(DTE is going to love you:) If you are outside of town and can get away with it, a two stage ground source heat pump may be your best bet (if you can get the air distribution). Either way, do your homework and know your contractor.
