Mitsubishi vs. Fujitsu

[pingable]

When looking at various ductless HVAC system/ We are primarily looking at the Fujitsu and Mitsubisi Mr. Slim series.

How does the Mr. Slims compare to the Fujitsu lineup.

We are also planning to look at Sanyo and Daikin as well.

[skippedover]

I'd recommend you spend more time on the company you'll be using for the installation and less time on the brand of equipment. We install Mr. Slim but that's our preference. Several of the mini-splits on the market are good but it's the company that installs and services the equipment that makes the difference. If you get a super cheap install price, it's worthless if you should have a problem and have no one to fix it. Many companies today will not service equipment if they bid the job and lost it to a lower bid. I'm not saying your searching for the lowest price but find the right contractor and you'll be happy, regardless the brand name.

sofar, the 3 shops I've talked to that are scheduled to look at the house seems trusting...but sometimes you never know until the 1 time you need them for customer service..

Shop A says Fujitsu is better the Mr.Slim
Shop B says Mr. Slim is like *mercedes* and Fujitsu is a Honda
Shop C is pushing Daikin. They rep Fujitsu and Mitsubishi as well, and rate both as more expensive, less reliable and cost more solutions...

Less reliable? We've put in at least 100 of the Mr. Slims and so far have had ONE, that's right ONE service call. That was in a very windy area where the outdoor unit fan stopped, presumably due to high wind. The tech reset the disconnect and the unit has run prefectly now for 2-years. Sounds to me like Shop C is afraid to sell features and benefits and wins their jobs on price alone. Not good. Here's a little test. As each shop goes through your home, tell them you're shopping all 3 manufacturers. Ask them to tell you about the features and benefits of the system they're recommending. Discard any company that spend more time bad mouthing the competition rather than focusing on the F&B of their recommended equipment. Shucks, our problem is we train the techs and they never get to use the knowledge on the Mr. Slims. That's a great benefit from where I sit! I just collect on the installation of 2 Mr. Slims, will be signing an agreement tomorrow for 2 more systems. Would we be selling something that's unreliable? Not with our customer base! We'd be out of business in no time. Warranty work is not what we want. Do the test though. I'll bet you can eliminate at least one or probably 2 of them just by listening.

Ain't that the truth.

Every system is different but for EACH run, is the general rule 2 3/4 hole - 3" required.

I'm just looking at the interior walls, looking at how I would want lines run versus not the easiest path for the installer, can I run *drag lines* from the condenser location to each...for the installer to use

3" hole seems awfully large though...I don't think running these inside along the joist is even a option if standard 2x4 framing is used.

I don't mind opening up the walls, running drags and patching up behind the installer but 3" is definitely is more like eating up the whole stud then fishing inside them...

[sjones]

Depending on the size of the unit you should have 2 lines running in the wall usually one line is 1/4" and the other is between 3/8"-5/8". Both with 1/2" insulation around the line. so no problem running up a wall. Just a matter of getting all that out of the wall.

They also make a Line Hide you can run up the outside of the wall and just put a hole strait through.

Got it. 2" bore on a 3 1/2 stud....

Hmmmm, gotta look that up. It's non load bearing studs but that sure is alot of meat to take out to fish and keep the lines in

Largest I've done is 3/4 and that was just running good ole BX cable.

I saw the Line Hides - SlimDucts

BTW, HOW FLUSH or low off the ceiling can these things be mounted.
Does it need to be at least X inches off the ceiling or can the wall units be close to almost flush...

I have been using a mitsubishi for some time now with trouble free operation.

How important is PLACEMENT of the unit as well. For example, while it would probably be best to put 2 small units spread out on the main floor, IF I put it the unit in a corner of the house, facing the ~shorter~ side of the house, as long as the vanes and positioned to blow towards the length, should I trust the COOL air will find it's way

For what it's worth, I've installed probably 15 Fujitsu systems and two of them eventually lost the control board. One lasted less than an hour and the other about 3 months.

Started installing surge protectors with the Fujitsu. So far so good.

Pretty easy to tell that he is doing this himself. Probably just had contractors over for information.

[pingable]

Just trying to be a informed consumer and walk into a situation with as much knowledge as possible....

I've googled and seen some pics of how the multi splits are done.
The least thing I would want is for the house to look like Cyclops with branches of runs all throughout the exterior of the house.

I like to do my own due diligence

Hi,
I hope if you have experience with Amcoraire slip are system as well.
Last year in May I purchased 6 units of Amcoraire with 4 of 9000 BTU are still running perfectly but 2 of 12000 BTU AWS121HX are having 2 differences.
Last week, one of them has the F1 code flashing on the oinside unit and anytime I started the fan of the inside unit running for about 30 seconds and the code F1 shows up.
The other one's problem just started today. last night i still used it and was good. This morning, when I started it up and the fan of the inside unit was running and after awhile I realized that what I got was only heat and heat.
It is still in the middle of summer. Amcoraire company is out of business. I don't where else asking for help. I searched on Google and I found you guys want to help people who are in problems.
I'm waiting for good news.
Thanks for your time.

Call a technician to take a look at it. They will have access to books that will have your error code listed and what is wrong.
