- View as the Ductless Plus Team installs a Mitsubishi Mini Split Heat Pump System in a Garage Office and two bedrooms in a beautiful home in Parker Colorado. Several Contractors had given our customer estimates and NOT recommended ceiling cassettes for this solution! Ceiling Cassettes Cosmetically make more sense in most situations because of the advantages that Jared covers in this install. Be sure and watch the Customer Testimonial at the end.

I agree with you as I plan to do all ceiling cassettes, like that you care about the way it will look when it’s finished, great work done by people who know what they are doing…….I give five ⭐️⭐️⭐️⭐️⭐️
Thank you!
Wow incredible work! No one is offering to install ceiling cassette in my area ..
Thank you for watching! I appreciate your kind words. Please give us a subscription!

I have 5 ceiling cassettes, they look great. I absolutely didn’t want holes drilled into the sides of my home with lines run along it to the condenser. My 5 lines all come from 2 holes in the attic. I have one wall mounted separate unit in the basement.. All Mitsubishi. Love the system over conventional whole house HVAC..
@@tjinytjiny6615 thank you
Great Job... Important for clients to see the mess it is to run piping (or work) in an attic with blown in insulation. When they say "how much to install?" Now they no why. Only concern was in the intake to the condensor (air) in in front of a dryer vent. Guess that makes for a customer that will always need the coil cleaned
That's a combustion Air vent not a dryer vent. Thanks for watching.
You can see the other Combustion vent down a little from this one. They want 2 combustion air ducts to the furnace.
I’ve watched many of your videos and a couple of months ago they convinced me to get the ceiling to sit in a multi zone Mitsubishi system. I went to the only diamond dealer in my area and they recommended and installed a system with two 9K ceiling cassettes in my roughly 860 square-foot basement because those are the smallest ones they could get. They said they couldn’t get the 6K ceiling cassettes.
And a 24K Wall mount unit for my garage. The garage is only about 560 square-foot, but I want it to be able to bring the temperature down even if I pulled a hot car in and the company and myself thought that the 24 would do a lot better than 18,000 that was there before. All of this is run to a NTXMMX36A142AA 36k 4 port outdoor unit.
The issue I’m having is that I cannot get maximum cooling from my 24K garage unit without turning off one of the basement units. I can only get about 56 to 58° air to come out of the garage unit with both basement units on if I turn one or both of the basement unit off the air coming out will get down to 46°.
If all three units are on and set to 65°, the air coming out of all units are around 56° at the coldest.
The company is saying that there should be no issues with that 36K outside unit even though the inside heads equals 42K.
My question is, are you of that same opinion or do you think they should have installed a 42K outside unit?
I’m just trying to get my stuff operating properly. Thanks for any advice you can give.
We never over size the indoor units. I match the totals from inside to outside.
@@ductlessplushvac great. I’m not sure how to handle this because I’ve spent $26,000 getting the system installed. And I know they’re not going to want to replace that 36 with a 42 and not charge me more. If they want to do it at all and admit it was a mistake.
Just talk with them.
@@ductlessplushvac I am talking back and forth with them. Hopefully they make it right being a diamond installer. They seem like great people but you never know
@@KnightsGarage Mitsubishi will give them a new unit (1) time a year for emergencies like yours just ask them to see if they can do that.
This is th ebest option for the people who don't want to mount wall unit. Great job. Here's a question in regards to installation. Is there any mold issue in the attic after installation? Any condensed water can be created around the ceiling unit in the attic?
Nope you will not have that problem
awesome. Thanks for the reply. @@ductlessplushvac
This is really great information since I was looking for ceiling cassette installation not the mount wall heat pump. How can we fix when the pump is failed?
Everything is serviced from below
Hi, my house has no attic space, it's a flat roof, will this system still work? Your video is super helpful. Thank you!!!
You can but sometimes you have to do framing and drywall work.
Some of my rooms don’t have deep enough ceiling joists for these units and the HVAC contractor is suggesting to just box them out 2-3 inches under the ceiling - thoughts on if this will look okay or am I just better off going with a regular wall mounted unit? I think as long as one side is flush to the wall it’ll still look better?
That's definitely (1) option. I don't think it would look bad.
How small or should I ask how large of a room was the 6k unit installed. Including ceiling height
Looks good.
Thanks Otto! Your the best!
Could you have run a branch box in the attic to avoid running 3 line set runs down the garage wall and out of the house?
We could have but a branch box system is very expensive and the outdoor unit has to be a 36k or 3ton unit for that. So it would be a bit overkill they only needed the 30k or 2.5 ton system saved them several thousands of dollars $
Ever retrofit one on the first floor of a two story home (not in the attic)?
Yes many times
That’d be a good vid next time around.
Horizontal discharge. You don't have 10 ft clearance to that fence.
What? You don’t need 10 feet bro hahaha!
Have you guys ever run the lines through a 4” or 6” pvc pipe, as opposed to running them side by side?
We have under gound. Why would you use that when you can use line-hide? That customer is going to build the wall out and box them lines in. 4” & 6” PVC IS HUGE.
@@ductlessplushvac 🤔wait..
…Let me clarify…
… when running the lines through an inaccessible ( for a person ) crawl space
One could access an entrance to the inaccessible crawl space and connect & push the pvc pipe over the joists to an ‘accessible area’ to make it possible for the lines to pass through the inaccessible area.
I was curious as to the diameter of the pvc that would be required to allow the lines to easily pass through to the accessible side.
Once the lines reach the accessible side, then one could pull the lines to the air handler. It would be a ‘real fun job’…
… well, maybe not 😄
Did you guys ever have a situation like that?
@@stepside2839 nope. And sorry just seen this text.
I thought ceiling cassettes needed to have access from above and condensate lines need to be insulated if ran through the attic. They are by far better looking.
We have them blown out
@@ductlessplushvac sorry, i don't know what you mean "blown out"
@@jerryjason8091 like a sprinkler system
These ceiling cassettes look amazing. I’ve been told by everyone in the area to run a gravity fed drain line and not the pump fed lines. Because pumps clog up and flood your ceiling/wall and floor. Is that an option on a ceiling cassette? To have a gravity condensation line? And have you ever had any problems with the pumps failing and making a problem? Thanks
I’ve installed hundreds of units and I haven’t had 1 pump break.
That’s good to know. On the ceiling cassettes can you access the pump from under the drywall and ceiling? I don’t have an addict so I won’t have any access after I finish the ceiling.
@@briandunn9700 yes all service is done from below you don’t need to get above the unit ever.
How can you install one of these units in a lived in home on the first floor with a second floor?? Have you done it? Do you need to repair the sheet rock after?? Thank you & your job looks great.
@@paulconnolly2969 yes we have and sometimes no drywall repair.
Love your channel and videos!
For this customer, Why not an MXZ-SM42 with a branch box?
Do you install surge suppressors or icm493 voltage watch guards?
They didn't need a MXZ-SM42 the 30 is sized just right. We use a DSB PROGRAM and sized it with that.
How would you heat and cool a restroom space?
@@timgroh8616 not with a ductless unit unless the room was very large. You can use in-floor heating. You typically don't require conditioning in a bathroom. If you take a shower you will heat it. And if you have a bath exhausted it will bring in air from the living space and totally keep the room comfortable.
I'm looking to build a quonsent home with an upstairs loft, so would it be possible to use the ceilingmount units under the upstairs floor? Installation would be prior to completing the floor upstairs.
Also, a crawlspace on either side of the loft would be an option.
You can install them in any flat ceiling
Do you know if they offer some sort of better filter for those ceil units?
I haven't seen one
Did you have to cut any joist to fit those ceiling cassettes in?
You shouldn’t have to cut any.
Is there a wireless adapter or programmable remote to use with a 40MBCQ (Bryant) cassette?
No
Can you install these on an angled ceiling.
No must be a flat ceiling
You don’t need a branch box for this unit?
Nope only on 36k units and up that are hyper-heating get BB
Nice work. Where does the drain line terminate?
Outside with the piping you can see it in the video.
@@ductlessplushvac Thanks for the reply. I have seen awful drain terminations that terminate near the foundation creating an always wet situation and it eventually damages the foundation and walls (leaching water) up into the framing. It would be nice if you explained in a future video, the right way to pipe the condensate drains. Thanks in advance and I enjoy your videos 🙂
@@terrylewis5786 thanks Terry!
How will you hook up all 3 drains?
We run them from the indoor heads drain line with 3/4” PVC and run the pipes outside side with the main refrigerant lines.
On a 4 zone system do I need touse a branch box
If it's a hyper heat
Hi there. Where can I get 6k btu compressor and indoor unit please.
I can get you one just call 720-355-0488
Love your guy's work and channel! I am looking at cooling my office with a 6000 btu unit. What heat pump would you recommend? I only need cooling, no heat.
For the price difference just get a heat pump it's minimal
What size hole did you drill in the siding for the line sets?
2”
Are the units pre charged?
All outdoor units are pre charged (Not the indoor units) that’s why you need to do a DSB
Do you only install or do you sell the equipment also? 😊
We only sell and install.
