Ductless Mini Split


Any of you guys have any experience with a mini split providing heat & A/C in your own home?

Rep says I need a 2 zone system and it will heat & cool my house with only 2 heads.

I'm skeptical.....

I have installed several mini splits but they are in computer server rooms and only have to cool.

Re: Ductless Mini Split


2 would work with one in the bedroom, one in the living room but if one has more rooms one wants more heads; Depends on how big the house is, I like the 'more is better' technique.

Re: Ductless Mini Split


Efficient, comfortable, quiet, steady heat or cool for a climate like yours. But 2 heads might be pushing it unless it's a VERY open floor plan or VERY well insulated.

Little Brother has a home in historic area with baseboard heat. Been talking to him about going from window units to something esle.

We are aging out - few more years and he won't be able to heft those window units.

Re: Ductless Mini Split


Depends on how many walls in the home. Great for open space heating and cooling. But if rooms are going to be closed off for privacy, or whatever reason, not so great.


The other reservation I would have is parts, should something fail. Finally, those cassettes aren't all that attractive, and take up a bit of wall space for decorating.



They have their advantages, especially if ducting isn't all that feasible. But, for the part, ducting is the best way to go if one needs both heating and cooling.

Re: Ductless Mini Split


I'm surprised some people are stating mini splits aren't good for closed space homes. I have customers that want cooling and heating in two focused areas such as a family room and a hot upstairs bedroom, and a 2 zone mini split worked wonderful for them and was much more cost effective than a whole home HVAC split system.

Why the hell would you replace that with a mini split?

Re: Ductless Mini Split


I'very got a 1000 Sq foot log cabin that is a bit drafty. It's got a 36000 BTU Mitsubishi mini split with 3 indoor units. It does an ok job of cooling, but struggles to heat it when it under 45 degrees.

Re: Ductless Mini Split


I just finished installing a DIY 12k BTU mini split last week. We choose to try a mini split after knocking down a couple of walls and throwing up a couple beams. The cost to install it was thousands less than installing dedicated ducts on exterior walls from the basement in a balloon framed house build in late 1890.

The brand was MRCOOL from Amazon. $1261.60 delivered. The install took me about 6 hours. The hardest part being running the 25' copper lines thru a knee wall, out the soffit, thru 3x4 downspout and connecting them without leaks or kinks.

The outdoor portion is pre-charged somehow and once connected via the copper lines you open two hex screws and it releases the refrigerant. The old window unit blew 66 while the new mini split blew 51. Tested with the same thermometer about 20 minutes apart. It was easily 90 degrees outside.

It works much better than the 18k BTU window unit it replaced. Its also whisper quiet. A local HVAC contractor that I have had good pricing from in the past quoted me $4450 for a Fujitsu 18k.
