Ductless Mini Split That Can HEAT and COOL Together!

In this video, Joshua Griffin discusses a concern many homeowners have when they have a multi-zone mini-split system. Most of these systems can not heat and cool at the same time having two different indoor units in a different modes. These units must be in the same mode if installed on the same outdoor unit for the system to operate. Joshua gives a solution to this issue that many systems that are used more in commercial atmospheres with heat recovery technology. Installing one of these systems in a home may give a homeowner added capability and comfort.

Wow that was my question in the live stream. Great to see you made a video about it. I’m very interested to see this technology come to more residential products in the future and see all the brands compete to make it better for customers overall. Having more choice is good. I know LG has LGRed that is available for residential. Most other brands have it available also but in light commercial systems that can still be used for residential. For example, Samsung has a system that is light commercial.

Josh, I have always liked your honesty in describing pros and cons with HVAC gear. May I add. Commenting before and receiving a reply from you in the comment section let me say a bit of something I found with my Mitsu system. I have 3 handlers on a 30K btu ODU. I learned last year (my first year with the new setup), not only the well known fact about what you state here about heat or cooling only at a time

I found out, at least with this brand, you CAN NOT even run it in FAN mode in any one air handler unless they are ALL in FAN mode ! I wanted to leave AC on in the main part of the home, but just circulate air in the master bedroom while sleeping. Simply put, could NOT do it. I am not sure if other brands have this same scheme or not. What can you add?

Thanks, and I do catch your Tuesday night 'shows' 🙂

Ive started my research into heat pumps as my existing setup is starting to show its age.

Considering just doing my upstairs zone first and have been debating between doing individual dedicated mini splits for each room or a multi split.

Contrary to what I expected, for some reason individual mini splits seem like they wouldn’t actually cost more money, and come with a benefit of actually being far more efficient, especially since 2 of my bedrooms are a fair bit larger than the other 2 smaller bedrooms.

Didn’t even hear about heat recovery units, but the concept makes sense. Though individual mini splits also prevent this issue as well.

I guess it depends on install complexity for cost of individual vs multi split, but the more I research, the less a multi split seems to make sense…

Heat recovery multi splits seem like the only thing that could change this, as it could take advantage of excess heat in certain areas for use in other areas.

I’m actually surprised that no one has come out with a whole home solution yet, connecting heating or cooling sources within the house. Such as refrigerators, washing machines or dryers, dishwashers, hvac, etc.

Hi Josh! Thanks so much for all of your info on the ins and outs of mini splits. I had lived in Tokyo for 6 years back in the early 2000s and I had LOVED both my Daikin and National (the parent company of Panasonic) units. They were so awesome to have since the humidity in most of Japan is just awful in the summer. Do you happen to know of any Daikin or Mitsubishi installers here in my home state of Colorado/Denver area that are reputable (or perhaps your Daikin sales rep may know)? If you don't that's OK. I'm just trying to find someone locally like yourselves that do a great job as an HVAC tech and know how to install/repair these units. Thanks again! Christine in sunny CO

i have been doing heating and air for like 8 years now. im in Pennsylvania and any mini split system i had a service call on is a nightmare. tech support for hours--2 week wait for parts. --control boards that cost 400 dollars. i would just tell customers to stick to the old school stuff. parts easy to find . i work on alot of boilers up here--mainly steam but some reg boilers, but also probably around the 50, s and 60, s. reg central air i think is better and just shut your heat vent if your too cold.

It’s important to mention that those brands only offer heat recovery in 3 phase systems.

Samsung and I believe LG have heat recovery in single phase, which is a game changer.

I would appreciate your insight . I have a 875 sqft 2 bedroom 2 floor home . I would like to use mini split multi zone unit to provide heat and a/c through the home any suggestions ?

Thanks for the info, very helpful. Have you done a video on a ducted minisplit system? Looking to replace my central system with apparently a heat recovery unit!

I want one that actually makes snow in my house
