Mini-split unit on roof

Hi Joe @HomeAirInc, per ashton13’s recommendation I have been trying to get a quote or a site visit from you guys but you have been very slow to respond to my emails. Hope Sam comes down off that ladder soon to reply : )

Hi ashton13,

Great to hear the minisplit worked out for you.
If you don’t mind me asking, what exact line of products from Mitsubishi did you use? We are doing our renovation and had ‘SEZ’ units spec’d initially, but where told to go with ‘city multy’ as our planned duct runs are presumably too long for SEZ to handle. However, we suspect the ‘city multi’ might be much more expensive. We would be very grateful for any info on this.

Hey. The steel beams should be big enough to carry the weight of the condenser on their own, without the help of the wood beams. The “mini beams” sound like they were put there to distribute the weight of the condenser over several joists, or just to lift the unit off of the roof. Both are good ideas, but neither is acceptable if you have wood joists holding up those steel beams.

Sorry for the delay – was out of town for a few days. We have two of the M-series wall-mounted units on one floor (https://innovations.mitsubishi-les.com/en/m-series/msz-ef) and one in-ceiling unit on the other (https://innovations.mitsubishi-les.com/en/m-serie/sez-kd). The ducts for the ceiling unit don’t have to go far – we were able to locate it right in the middle of the floor plan above a new bathroom, and from there it branches into three adjacent rooms. The longest run is maybe 10-12 feet. We are extremely happy with all of it – we wish we could have done ceiling units on both floors, but we have low ceilings and exposed joists, so that was a no-go. They are all silent (the in-ceiling – literally) or nearly, and do a great job. The outdoor units are super quiet as well – we put them in the front on the ground bc we didn’t want to have to see them in the back yard (frame house – Sam said if we wall mounted them there would be vibration, and roof mounted, obv per this thread, is complicated, plus they would have had to pipe through our rental unit, and the runs may have been too long, etc) and I was concerned that they’d be noisy, but they barely make any sound at all. I have to underscore my recommendation for Sam at Home Air – we were getting an error code on the remote panel for the ceiling unit, so I emailed him last night at about 9pm. He called me back within a half hour and talked me through a few things to check (power cycling the breaker reset the system and got it going again). Had that not fixed it, he would have come by tonight to check it out in person.

Ashton, once again, thank you for the compliments.

If there is any questions regarding mini-splits, installations, or HVAC related topics, please feel free to email us at INFO@homeairinc.com, with “Brownstoner,” in the subject line, and we will respond quickly – sometimes emailing or calling Sam directly is a little complicated, as he maybe in the middle of an installation or service call, and on a ladder.

I will be more then happy to answer any questions I can or get you pointed in the right direction.
